     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    This invention is directed to systems and methods on wellbore operations rigs for identifying items; and, in certain aspects to identifying items on drilling rigs such as tubulars and drill pipe, using mat(s) with energizing apparatus and with wave-energizable apparatuses, e.g., radio frequency identification tags and surface acoustic wave tags. 
         [0004]    2. Description of Related Art 
         [0005]    The prior art discloses a variety of systems and methods for using surface acoustic wave tags or radio frequency identification tags in identifying items, including items used in the oil and gas industry such as drill pipe. (See e.g. U.S. Pat. Nos. 4,698,631; 5,142,128; 5,202,680; 5,360,967; 6,333,699; 6,333,700; 6,347,292; 6,480,811; and U.S. patent application Ser. Nos. 10/323,536 filed Dec. 18, 2002; 09/843,998 filed Apr. 27, 2001; 10/047,436 filed Jan. 14, 2002; 10/261,551 filed Sep. 30, 2002; 10/032,114 filed Dec. 21, 2001; and 10/013,255 filed Nov. 5, 2001; all incorporated fully herein for all purposes.) In many of these systems a radio frequency identification tag or “RFIDT” is used on pipe at such a location either interiorly or exteriorly of a pipe, that the RFIDT is exposed to extreme temperatures and conditions downhole in a wellbore. Often an RFIDT so positioned fails and is of no further use. Also, in many instances, an RFIDT so positioned is subjected to damage above ground due to the rigors of handling and manipulation. 
         [0006]    The present inventors have realized that, in certain embodiments, substantial usefulness for a tubular identification system can be achieved by divorcing the desire for effective above-ground identification and operation from the goal of downhole accessibility. 
       SUMMARY OF THE PRESENT INVENTION 
       [0007]    The present invention, in certain aspects, discloses and teaches a rig for wellbore operations, e.g., but not limited to, a drilling rig, with a rig floor over which is located a mat or mats containing apparatus for energizing and communicating with wave-energizable devices in or on items, such as pipe and/or equipment, which are moved with respect to, above and/or through the rig floor. In certain particular aspects, one mat or multiple mats are provided on a rig floor, each with energizing apparatus, so that a desired operational energizing pattern is created above the rig floor into which and through which an item, such as drill pipe, is moved. In certain particular aspects, the energizing apparatuses are such that, and are operated in such a way, that an energizing pattern above a rig floor has a predetermined height, shape, and extent to correspond to specific items and their movement, e.g., but not limited to, tubulars, pipe, top drives, elevators, pipe handlers, and tongs. 
         [0008]    The present invention, in certain aspects, discloses and teaches a rig with one or multiple, interlocked floor mats, each with one or more apparatuses for energizing wave-energizable devices in or on items. 
         [0009]    The present invention, in certain aspects, discloses and teaches a rig with a mat or mats according to the present invention which are used with an iron roughneck, a mousehole, a rathole, a flush mounted rotary table, or with a raised rotary table. 
         [0010]    The present invention discloses, in certain aspects, a rig for wellbore operations having: a rig floor; at least one mat on the rig floor; and energizing apparatus associated with the mat or mats for energizing wave-energizable apparatus (e.g. an RFID tag or a SAW tag) on an item, pipe, and/or equipment movable with respect to the mat or mats. 
         [0011]    The present invention discloses, in certain aspects, a mat for use in rig wellbore operations, the mat including: a mat body; energizing apparatus associated with (e.g. in or on) the mat body for energizing wave-energizable apparatus on an item, e.g., usable in a rig operation movable with respect to the mat, the item usable in a rig operation. 
         [0012]    The present invention discloses, in certain aspects, a method for energizing wave-energizable apparatus adjacent a rig floor of a rig, the method including: moving an item, etc., with wave-energizable apparatus adjacent a rig floor of a rig, the rig for wellbore operations, the item usable in a rig operation, and the rig having a rig floor, a mat or mats on the rig floor, and energizing apparatus associated with the mat or mats for energizing the wave-energizable apparatus; and with the energizing apparatus, energizing the wave-energizable apparatus. 
         [0013]    The present invention, in certain aspects, provides an item, an apparatus, or a tubular, e.g. a piece of drill pipe, with a radio frequency identification tag either affixed exteriorly to the item, apparatus or tubular or in a recess in an end thereof so that the RFIDT is protected from shocks (pressure, impacts, thermal) that may be encountered in a wellbore or during drilling operations. In one particular aspect one or more RFIDT&#39;s are covered with heat and/or impact resistant materials on the exterior of an item. In one particular aspect, the present invention discloses systems and methods in which a piece of drill pipe with threaded pin and box ends has one or more circumferential recesses formed in the pin end into which is emplaced one or more radio frequency identification tags each with an integrated circuit and with an antenna encircling the pin end within A recess. The RFIDT (OR RFIDT&#39;S) in a recess is protected by a layer of filler, glue or adhesive, e.g. epoxy material, and/or by a cap ring corresponding to and closing off the recess. Such a cap ring may be made of metal (magnetic; or nonmagnetic, e.g. aluminum, stainless steel, silver, gold, platinum and titanium), plastic, composite, polytetrafluoroethylene, fiberglass, ceramic, and/or cermet. The RFIDT can be, in certain aspects, any known commercially-available read-only or read-write radio frequency identification tag and any suitable known reader system, manual, fixed, and/or automatic may be used to read the RFIDT. 
         [0014]    The present invention, in certain aspects, provides an item, apparatus, or tubular, e.g. a piece of drill pipe, with one or more radio frequency identification tags wrapped in heat and impact resistant materials; in one aspect, located in an area 2-3″ in length beginning ½ from the 18 degree taper of the pin and drill pipe tool joint so that the RFIDT (or RFIDT&#39;s) is protected from shocks (pressure, impacts, thermal) that may be encountered on a rig, in a wellbore, or during wellbore (e.g. drilling or casing) operations. In one particular aspect, the present invention discloses systems and methods in which a piece of drill pie with threaded pin and box ends has one or more radio frequency identification tags each with an integrated circuit and with an antenna encircling the pin end upset area located exteriorly on the pipe, e.g. in an area ½″-2½″ from a pin end  18  degree taper. The RFIDT (or RFIDT&#39;s) is protected by wrapping the entire RFIDT and antenna in a heat resistant material wrapped around the circumference of the tube body and held in place by heat resistant glue or adhesive, e.g. epoxy material which encases the RFIDT. This material is covered with a layer of impact resistant material and wrapped with multiple layers of wrapping material such as epoxy bonded wrap material. Preferably this wrapping does not exceed the tool joint OD. The RFIDT can be (as can be any disclosed herein), in certain aspects, any known commercially-available read-only or read-write radio frequency identification tag and any suitable know reader system, manual, fixed, and/or automatic may be used to read the RFIDT. Such installation of RFIDT&#39;s can be carried out in the field, in a factory, on a rig, with no machining necessary. Optionally, a metal tag designating a unique serial number of each item, apparatus, or length of drill pipe located under the wrap with the RFIDT(s) insures “Traceability” is never lost due to failure of the RFIDT(s). Replacement of failed RFIDT&#39;s can be carried out without leaving a location, eliminating expensive transportation or trucking costs. Optionally the wrap is applied in a distinctive and/or a bright color for easy identification. Determining whether an item, apparatus, or a tubular or a length of drill pipe or a drill pipe string is RFID-tagged or not is visibly noticeable, e.g. from a distance once the RFIDT&#39;s are in place. 
         [0015]    In certain particular aspects an RFIDT is encased in a ring of protective material whose shape and configuration corresponds to the shape of the pin end&#39;s recess and the ring is either permanently or removably positioned in the recess. Such a ring may be used without or in conjunction with an amount of protective material covering the ring or with a cap ring that protectively covers the RFIDT. Two or more RFIDT&#39;s may be used in one recess and/or there may be multiple recesses at different levels. In other aspects a ring is provided which is emplaceable around a member, either a generally cylindrical circular member or a member with some other shape. 
         [0016]    With an RFIDT located in a pipe&#39;s pin end as described herein, upon makeup of a joint including two such pieces of pipe, an RFIDT in one pipe&#39;s pin end is completely surrounded by pipe material—including that of a corresponding pipe&#39;s box end—and the RFIDT is sealingly protected from access by materials flowing through the pipe and from materials exterior to the pipe. The mass of pipe material surrounding the enclosed RFIDT also protects it from the temperature extremes of materials within and outside of the pipe. 
         [0017]    In other aspects [with or without an RFIDT in a recess] sensible material and/or indicia are located within a recess and, in one aspect, transparent material is placed above the material and/or indicia for visual inspection or monitoring; and, in one aspect, such sensible material and/or indicia are in or on a cap ring. 
         [0018]    A pipe with a pin end recess as described herein can be a piece of typical pipe in which the recess is formed, e.g. by machining or with laser apparatus or by drilling; or the pipe can be manufactured with the recess formed integrally thereof. In certain particular aspects, in cross-section a recess has a shape that is square, rectangular, triangular, semi-triangular, circular, semi-circular, trapezoid, dovetail, or rhomboid. 
         [0019]    It has also been discovered that the location of an RFIDT or RFIDT&#39;s according to the present invention can be accomplished in other items, apparatuses, tubulars and generally tubular apparatuses in addition to drill pipe, or in a member, device, or apparatus that has a cross-section area that permits exterior wrapping of RFIDT(s) or circumferential installation of antenna apparatus including, but not limited to, in or on casing, drill collars, (magnetic or nonmagnetic) pipe, thread protectors, centralizers, stabilizers, control line protectors, mills, plugs (including but not limited to cementing plugs), and risers; and in or on other apparatuses, including, but not limited to, whipstocks, tubular handlers, tubular manipulators, tubular rotators, top drives, tongs, spinners, downhole motors, elevators, spiders, powered mouse holes, and pipe handlers, sucker rods, and drill bits (all which can be made of or have portions of magnetizable metal or nonmagnetizable metal). 
         [0020]    In certain aspects the present invention discloses a rig with a rig floor having thereon or embedded therein or positioned therebelow a tag reader system which reads RFIDT&#39;s in pipe or other apparatus placed on the rig floor above the tag reader system. All of such rig-floor-based reader systems, manually-operated reader systems, and other fixed reader systems useful in methods and systems according to the present invention may be, in certain aspects, in communication with one or more control systems, e.g. computers, computerized systems, consoles, and/or control system located on the rig, on site, and/or remotely from the rig, either via lines and/or cables or wirelessly. Such system can provide identification, inventory, and quality control functions and, in one aspect, are useful to insure that desired tubulars, and only desired tubulars, go downhole and/or that desired apparatus, and only desired apparatus, is used on the rig. In certain aspects one or more RFIDT&#39;s is affixed exteriorly of or positioned in a recess an item, apparatus, or tubular, e.g., in one aspect, in a box end of a tubular. In certain aspects antennas of RFIDT&#39;s according to the present invention have a diameter between one quarter inch to ten inches and in particular aspects this range is between two inches and four inches. Such systems can also be used with certain RFIDT&#39;s to record on a read-write apparatus therein historical information related to current use of an item, apparatus or of a tubular member; e.g., but not limited to, that this particular item, apparatus, or tubular member is being used at this time in this particular location or string, and/or with particular torque applied thereto by this particular apparatus. 
         [0021]    In other aspects, a pipe with a pin end recess described therein has emplaced therein or thereon a member or ring with or without an RFIDT and with sensible indicia, e.g., one or a series of signature cuts, etchings, holes, notches, indentations, alpha and/or numeric characters, raised portion(s) and/or voids, filled in or not with filler material (e.g. but not limited to, epoxy material and/or nonmagnetic or magnetic metal, composite, fiberglass, plastic, ceramic and/or cermet), which indicia are visually identifiable and/or can be sensed by sensing systems (including, but not limited to, systems using ultrasonic sensing, eddy current sensing, optical/laser sensing, and/or microwave sensing). Similarly it is within the scope of the present invention to provide a cap ring (or a ring to be emplaced in a recess) as described herein (either for closing off a recess or for attachment to a pin end which has no such recess) with such indicia which can be sensed visually or with sensing equipment. 
         [0022]    It is within the scope of this invention to provide an item, apparatus, or tubular member as described herein exteriorly affixed (RFIDT(s) and/or with a circular recess as described above with energizable identification apparatus other than or in addition to one or more RFIDT&#39;s; including, for example one or more surface acoustic wave tags (“SAW tags”) with its antenna apparatus in the circular apparatus.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0130]      FIGS. 1A-1C  show a pin end  10  of a drill pipe according to the present invention which has a sealing shoulder  12  and a threaded end portion  14 . A typical flow channel  18  extends through the drill pipe from one end to the other. A recess  20  in the top  16  (as viewed in  FIG. 1C ) of the pin end  10  extends around the entire circumference of the top  16 . This recess  20  is shown with a generally rectangular shape, but it is within the scope of this invention to provide a recess with any desired cross-sectional shape, including, but not limited to, the shapes shown in  FIG. 1D . In one aspect an entire drill pipe piece with a pin end  10  is like the tubular shown in  FIG. 3A  or the drill pipe of  FIG. 12B . The recess  20  (as is true for any recess of any embodiment disclosed herein) may be at any depth (as viewed in  FIG. 1C ) from the end of the pin end and, as shown in  FIGS. 1A-1C  may, according to the present invention, be located so that no thread is adjacent the recess. 
         [0131]    It is within the scope of the present invention to form the recess  20  in a standard piece of drill pipe with a typical machine tool, drill, with a laser apparatus such as a laser cutting apparatus, or with etching apparatus. Alternatively, it is within the scope of the present invention to manufacture a piece of drill pipe (or other tubular) with the recess formed integrally in the pin end (and/or in a box end). The recess as shown in  FIG. 1C  is about 5 mm wide and 5 mm deep; but it is within the scope of certain embodiments of the present invention to have such a recess that is between 1 mm and 10 mm wide and between 2 mm and 20 mm deep. 
         [0132]    A cap ring  22  is installed over the recess  20  which seals the space within the recess  20 . This cap ring  22  (as may be any cap ring of any embodiment herein) may be made of any suitable material, including, but not limited to: metal, aluminum, zinc, brass, bronze, steel, stainless steel, iron, silver, gold, platinum, titanium, aluminum alloys, zinc alloys, or carbon steel; composite; plastic, fiberglass, fiber material such as ARAMID™ fiber material; KEVLAR™ or other similar material; ceramic; or cermet. The cap ring  22  may be sealingly installed using glue, adhesive, and/or welding (e.g., but not limited to Tig, Mig, and resistance welding and laser welding processes). 
         [0133]    Disposed within the recess  20  beneath the cap ring  22 , as shown in  FIG. 1C , is an RFIDT device  28  which includes a tag  24  and an antenna  26 . The antenna  26  encircles the recess  20  around the pin end&#39;s circumference and has two ends, each connected to the tag  24 . The RFIDT tag device may be any suitable known device, including, but not limited to the RFID devices commercially available, as in  FIG. 2 , e.g. from MBBS Company of Switzerland, e.g. its E-Units™ (TAGs) devices e.g., as in  FIG. 2 . The RFIDT device  28  may be a read-only or a read-write device. It is within the scope of this invention to provide one, two, three or more such devices in a recess  20  (or in any recess of any embodiment herein). Optionally, the RFIDT device (or devices) is eliminated and a recess  20  with a particular varied bottom and/or varied side wall(s) and/or a cap ring with a nonuniform, varied, and/or structured surface or part(s) is used which variation(s) can be sensed and which provide a unique signature for a particular piece of drill pipe (as may be the case for any other embodiment of the present invention). These variations, etc. may be provided by different heights in a recess or different dimensions of projections or protrusions from a recess lower surface or recess side wall surface, by etchings thereon or on a cap ring, by cuts thereon or therein, and/or by a series of notches and/or voids in a recess and/or in a cap ring and/or by sensible indicia. Optionally, instead of the RFIDT device  28  (and for any embodiment herein any RFIDT) a SAW tag may be used and corresponding suitable apparatuses and systems for energizing the SAW tag(s) and reading them. 
         [0134]    In certain aspects of the present invention with a recess like the recess  20  as described above, a ring or torus is releasably or permanently installed within the recess with or without a cap ring thereover (like the cap ring  22 ). Such a ring or torus may have one, two, or more (or no) RFIDT&#39;s therein.  FIGS. 2A and 2B  show a torus  30  installable within a recess, like the recess  20  or any recess as in  FIG. 1C , which includes a body  31  with a central opening  31   a . An RFIDT  32  is encased on the body  31 . The RFIDT  32  has an integrated circuit  33  and an antenna  34  which encircles the body  31 . In certain aspects the body  31  (as may be any body of any torus or ring according to the present invention) is made of metal, plastic, polytetrafluorethylene, fiberglass, composite, ceramic, or of a nonmagnetizable metal. The opening  31   a  (as may be any opening of any torus or ring herein) may be any desired diameter. Optionally, or in addition to the RFIDT device  28 , and RFIDT device  28   a  (or devices  28   a ) is affixed exteriorly to the pin end  10  with a multi-layer wrap as described below (see  FIGS. 28 ,  26 ) [any RFIDT(s) or SAW tag(s) may be used for the RFIDT  28   a].    
         [0135]      FIGS. 2C and 2D  show a torus  35  which has a central opening  35   a , a body  36  and an RFIDT  37  therein with an antenna  38  that encircles the body  36  and an integrated circuit  39 . In one aspect a recess  20   a  in a body for receiving a torus  35  has an upper lip  20   b  (or inwardly inclined edge or edges as shown in  FIG. 2D ) and the body  36  is made of resilient material which is sufficiently flexible that the torus  35  may be pushed into the recess  20   a  and releasably held therein without adhesives and without a cap ring, although it is within the scope of the present invention to use adhesive and/or a cap ring with a torus  35 . 
         [0136]      FIG. 2E  shows a torus  40  according to the present invention with a body  40   a  which is insertable into a recess (like the recess  20 , the recess  20   a , or any recess disclosed herein) which has one or more elements  41  therein which serve as strengthening members and/or as members which provide a unique sensible signature for the torus  40  and, therefore, for any pipe or other item employing a torus  40 . The torus  40  has a central opening  40   b  and may, according to the present invention, also include one, two or more RFIDT&#39;s (not shown). 
         [0137]      FIGS. 2F and 2G  show a torus  44  according to the present invention insertable into any recess disclosed herein which has a body  45 , a central opening  44   a , and a series of voids  46   a ,  46   b , and  46   c . With such a torus  44  made of metal, the voids  46   a - 46   c  can be sensed by any sensing apparatus or method disclosed herein and provide a unique sensible signature for the torus  44  and for any item employing such a torus  44 . Any torus described herein may have such a series of voids and any such series of voids may, according to the present invention, contain any desired number (one or more) of voids of any desired dimensions. In one particular aspect, a series of voids provides a barcode which is readable by suitable known barcode reading devices. A torus  44  can be used with or without a cap ring. As desired, as is true of any torus according to the present invention, one, two, or more RFIDT&#39;s may be used within or on the torus body. Voids may be made by machining, by drilling, by etching, by laser etching, by hardfacing or using a photovoltaic process. 
         [0138]      FIG. 2H  shows a torus  47  according to the present invention useful in any recess of any embodiment herein which has a series of sensible ridges  48   a - 48   f  which can be made by adding material to a torus body  49  [such a torus may have visually readable indicia, e.g. alpha (letter) and/or numeric characters]. Any torus, ring, or cap ring herein may have one or more such ridges and the ridges can have different cross-sections (e.g. as in  FIG. 2H ) or similar cross-sections and they can be any suitable material, including, but not limited to metal, plastic, epoxy, carbides, and hardfacing. Also, according to the present invention, a cap ring with one or more RFIDT&#39;s and/or any other sensible material and/or indicia disclosed herein may be placed around and secured to a tubular&#39;s pin end or box end without using a recess. 
         [0139]      FIG. 2M  shows a cap ring  22   a , like the cap ring  22 , but with sensible indicia  22   b - 22   f  made therein or thereon for sensing by an optical sensing system, an ultrasonic sensing system, an eddy current sensing system, a barcode sensing system, or a microwave sensing system. A cap ring  22   a  may be releasably or permanently installed in or over a recess like any recess disclosed herein. The indicia  22   b - 22   f  may be like any of the indicia or sensible structures disclosed herein. 
         [0140]      FIGS. 2I and 2J  show a specific cap ring  50  according to the present invention for use with drill pipe having a pin end. The ring  50  has a body with an outer diameter  50   a  of 98 mm, a thickness  50   b  of 5 mm, and a wall thickness  50   c  of 5 mm.  FIGS. 2K and 2L  show a specific cap ring  51  according to the present invention for use with a drill pipe pin end having an end portion diameter of about four inches. The ring  51  has an outer diameter  51   a  of 98 mm, a thickness  51   b  of 8 to 10 mm, and a wall thickness  51   c  of 3 mm. 
         [0141]    It is within the scope of the present invention to provide a tubular having a box end and a pin end (each threaded or not) (e.g. casing, riser, pipe, drill pipe, drill collar, tubing), each end with an RFIDT in a recess therein (as any recess described herein) with or without a cap ring (as any described herein).  FIGS. 3A-3C  show a generally cylindrical hollow tubular member  480  according to the present invention with a flow channel  480   a  therethrough from top to bottom and which has a threaded pin end  481  and a threaded box end  482 . The threaded box end  482  has a circumferential recess  483  with an RFIDT  484  therein. The RFIDT has an IC  485  and an antenna  486  which encircles the box end. Optionally, filler material  487  in the recess  483  encases and protects the IC  485  and the antenna  486 ; and an optional circular cap ring  488  closes off the recess. The RFIDT and its parts and the cap ring may be as any disclosed or referred to herein. Optionally, the tubular member  480  may have a shoulder recess  483   a  with an RFIDT  484   a  with an IC  485   a  and an antenna  486   a . Filler material  487   a  (optional) encases the RFIDT  484   a  and, optionally, a cap ring  488   a  closes off the recess. 
         [0142]    The pin end  481  has a circumferential recess  491  in which is disposed an RFIDT  492  with an IC  493  and an antenna  494  around the pin end. As with the box end, filler material and/or a cap ring may be used with the recess  491 . Antenna size is related to how easy it is to energize an IC and, therefore, the larger the antenna, the easier [less power needed and/or able to energize at a greater distance] to energize: and, due to the relatively large circumference of some tubulars, energizing end antennas is facilitated. 
         [0143]      FIG. 4A  shows a system  70  according to the present invention with a rig  60  according to the present invention which has in a rig floor  61  a reading system  65  (shown schematically) for reading one or more RFIDT&#39;s in a drill pipe  66  which is to be used in drilling a wellbore. The reading system  65  incorporates one or more known reading apparatuses for reading RFIDT&#39;s, including, but not limited to suitable readers as disclosed in the prior art and readers as commercially available from MBBS Co. of Switzerland. The present invention provides improvements of the apparatuses and systems disclosed in U.S. patent application Ser. No. 09/906,957 filed Jul. 16, 2001 and published on Feb. 7, 2002 as Publication No. 2002/0014966. In an improved system  70  according to the present invention a drill pipe  66  ( FIG. 4B ) is like the drill pipes 16 in U.S. patent application Ser. No. 09/906,957, but the drill pipe  66  has a recess  67  with a torus  68  therein having at least one RFIDT  69  (shown schematically in  FIG. 4B ) and a cap ring  68   a  over the torus  68 . The drill pipe  66  may be connected with a tool joint  76  to other similar pieces of drill pipe in a drill string  77  (see  FIG. 4A ) as in U.S. patent application Ser. No. 09/906,957 (incorporated fully herein) and the systems and apparatuses associated with the system  70  ( FIG. 4A  and  FIG. 4C ) operate in a manner similar to that of the systems  10  and the system of  FIG. 1B  of said patent application. Drill string  77  includes a plurality of drill pipes  66  coupled by a plurality of tool joints  76  and extends through a rotary table  78 , and into a wellbore through a bell nipple  73  mounted on top of a blowout preventer stack  72 . An identification tag (e.g. an RFIDT)  71  is provided on one or more drilling components, such as illustrated in  FIG. 4A , associated with the system  70 , or the drill pipe  66 . An electromagnetic signal generator system  74  that includes an antenna and a signal generator is positioned proximate to an identification tag, for example just below rotary table  78  as illustrated in  FIG. 4A . Electromagnetic signal generator system  74  establishes a communications link with an identification tag  71  to energize the antenna, interrogate it, and to convey information relating to the equipment or drill pipe. 
         [0144]    The drilling system  70  includes the rig  60  with supports  83 , a swivel  91 , which supports the drill string  77 , a kelly joint  92 , a kelly drive bushing  93 , and a spider  79  with an RFIDT sensor and/or reader  79   a . A tool joint  76  is illustrated in  FIG. 4A  as connecting two drilling components such as drill pipes  66 . The identification tag  71  (or the RFIDT  69  read by the system  65 ) is operated to communicate a response to an incoming electromagnetic signal generated by electromagnetic signal generator system  74  (or by the system  65 ) that includes information related to the drilling component with the identification tag. The information may be used, for example, to inform an operator of system  70  of a drilling component&#39;s identity, age, weaknesses, previous usage or adaptability. According to the teachings of the present invention, this information may be communicated while drill system  70  is in operation. Some or all of the information provided in an identification tag may assist an operator in making a determination of when drilling components need to be replaced, or which drilling components may be used under certain conditions. The electromagnetic signal communicated by an identification tag or RFIDT may provide general inventory management data (such as informing an operator of the drilling components availability on the drilling site, or the drilling component&#39;s size, weight, etc.), or any other relevant drilling information associated with the system. 
         [0145]    Additional drill string components  84 , which are illustrated in  FIG. 4A  in a racked position, may be coupled to drill pipe  66  and inserted into the well bore, forming a portion of the drill string. One or more of drill string components may also include identification tags or RFIDT&#39;s. 
         [0146]      FIG. 4C  shows typical information that may be included within an identification tag&#39;s or RFIDT&#39;s, antenna as the antenna cooperates with electromagnetic signal generator  74  and/or the system  65  to transmit an electromagnetic energizing signal  85  to an identification tag  71  (or  69 ). The electromagnetic signal generators use an antenna to interrogate the RFIDT&#39;s for desired information associated with a corresponding pipe or drilling component. 
         [0147]    The electromagnetic signal  85  is communicated to an RFIDT that responds to the transmitted electromagnetic signal by returning data or information  86  in an electromagnetic signal form that is received by one of the antennas, and subsequently communicated to a reader  87  which may subsequently process or simply store electromagnetic signal  86 . The reader  87  may be handheld, i.e. mobile, or fixed according to particular needs. 
         [0148]    The RFIDT&#39;s  69  and  71  may be passive (e.g. requiring minimal incident power, for example power density in the approximate range of 15-25 mW/cm 2 ) in order to establish a communications link between an antenna and the RFIDT. “Passive” refers to an identification tag not requiring a battery or any other power source in order to function and to deriving requisite power to transmit an electromagnetic signal from an incoming electromagnetic signal it receives via an antenna. Alternatively, an RFIDT (as may any in any embodiment herein) may include a battery or other suitable power source that would enable an RFIDT to communicate an electromagnetic signal response  86 . 
         [0149]    Antennas are coupled to reader  87  by any suitable wiring configuration, or alternatively, the two elements may communicate using any other appropriate wireless apparatus and protocol. The reader  87  is coupled to a control system which in one aspect is a computer (or computers)  88  which may include a monitor display and/or printing capabilities for the user. Computer  88  may be optionally coupled to a handheld reader  89  to be used on the rig or remote therefrom. Computer  88  may also be connected to a manual keyboard  89   a  or similar input device permitting user entry into computer  88  of items such as drill pipe identity, drill string serial numbers, physical information (such as size, drilling component lengths, weight, age, etc.) well bore inclination, depth intervals, number of drill pipes in the drill string, and suspended loads or weights, for example. 
         [0150]    The computer  88  may be coupled to a series of interfaces  90  that may include one or more sensors capable of indicating any number of elements associated with drill rig derrick  83 , such as: a block travel characteristic  90   a , a rotation counter characteristic  90   b , a drill string weight  90   c , a heave compensator  90   d , and a blowout preventer (BOP) distance sensor  90   e . A micro-controller may include one or more of these sensors or any other additional information as described in U.S. application Ser. No. 09/906,957. The control system may be or may include a microprocessor based system and/or one or more programmable logic controllers. 
         [0151]    A drill pipe  66  with an RFIDT  69  and an RFIDT  71  provides a redundancy feature for identification of the drill pipe  66  so that, in the event one of the RFIDT&#39;s fails, the other one which has not failed can still be used to identify the particular drill pipe. This is useful, e.g. when the RFIDT  71 , which has relatively more exposure to down hole conditions, fails. Then the RFIDT  69  can still be used to identify the particular piece of drill pipe. It is within the scope of the present invention for any item according to the present invention to have two (or more RFIDT&#39;s like the RFIDT  69  and the RFIDT  71 . Optionally, or in addition to the RFIDT  69 , an RFIDT  69   a  (or RFIDT&#39;s  69   a ) may be affixed exteriorly of the pipe  66  with wrap material  69   b  (as described below, e.g. as in  FIGS. 25-32 ). 
         [0152]      FIGS. 5A-5D  present improvements according to the present invention of prior art systems and apparatuses in U.S. Pat. No. 6,480,811 B2 issued Nov. 12, 2002 (incorporated fully herein for all purposes).  FIG. 5B  shows schematically and partially a drill pipe  91  with an RFIDT  92  (like the identifier assemblies 12, U.S. Pat. No. 6,604,063 B2 or like any RFIDT disclosed herein and with an RFIDT  99 , (as any RFIDT disclosed herein in a drill pipe&#39;s pin end). It is within the scope of the present invention to provide any oilfield equipment disclosed in U.S. Pat. No. 6,604,063 B2 with two (or more) RFIDT&#39;s (e.g., one in an end and one in a side, e.g. like those shown in  FIG. 5B ). 
         [0153]      FIGS. 5A ,  5 C and  5 D show an oilfield equipment identifying apparatus  100  according to the present invention for use with pipe or equipment as in  FIG. 5B  with two (or more) RFIDT&#39;s on respective pieces  114  of oilfield equipment. The RFIDT&#39;s may be any disclosed or referred to herein and those not mounted in a recess according to the present invention may be as disclosed in U.S. Pat. No. 6,480,811 B2 indicated by the reference numerals  112   a  and  112   b  on pieces of equipment  114   a  and  114   b  with RFIDT&#39;s in recesses according to the present invention shown schematically and indicated by reference numerals  109   a ,  109   b ; and/or one or more RFIDT&#39;s may be affixed exteriorly (see e.g.,  FIGS. 25 ,  26 ) to either piece  114  of oilfield equipment. Each of the identifier assemblies  112  and RFIDT&#39;s like  109   a ,  109   b  are capable of transmitting a unique identification code for each piece of pipe or oilfield equipment. 
         [0154]    The oilfield equipment identifying apparatus  100  with a reader  118  is capable of reading each of the identifier assemblies and RFIDT&#39;s. The reader  118  includes a hand-held wand  120 , which communicates with a portable computer  122  via a signal path  124 . In one embodiment, each identifier assembly  112  includes a passive circuit as described in detail in U.S. Pat. No. 5,142,128 (fully incorporated herein for all purposes) and the reader  118  can be constructed and operated in a manner as set forth in said patent or may be any other reader or reader system disclosed or referred to herein. 
         [0155]    In use, the wand  120  of the reader  118  is positioned near a particular one of the identifier assemblies  112  or RFIDT&#39;s. A unique identification code is transmitted from the identifier assembly or RFIDT to the wand  120  via a signal path  126  which can be an airwave communication system. Upon receipt of the unique identification code, the wand  120  transmits the unique identification code to the portable computer  122  via the signal path  124 . The portable computer  122  receives the unique identification code transmitted by the wand  120  and then decodes the unique identification code, identifying a particular one of the identifier assemblies  112  or RFIDT&#39;s and then transmitting (optionally in real time or in batch mode) the code to a central computer (or computers)  132  via a signal path  134 . The signal path  134  can be a cable or airwave transmission system. 
         [0156]      FIG. 5C  shows an embodiment of an oilfield equipment identifying apparatus  100   a  according to the present invention which includes a plurality of the identifier assemblies  112  and/or RFIDT&#39;s  109  which are mounted on respective pieces  114  of pipe or oilfield equipment as described above. The oilfield equipment identifying apparatus includes a reader  152 , which communicates with the central computer  132 . The central computer  132  contains an oilfield equipment database (which in certain aspects, can function as the oilfield equipment database set forth in U.S. Pat. No. 5,142,128). In one aspect the oilfield equipment database in the central computer  132  may function as described in U.S. Pat. No. 5,142,128. In one aspect the oilfield equipment identifying apparatus  100   a  is utilized in reading the identifier assemblies  112  (and/or RFIDT&#39;s  109 ) on various pieces  114  of pipe or oilfield equipment located on a rig floor  151  of an oil drilling rig. 
         [0157]    The reader  152  includes a hand-held wand  156  (but a fixed reader apparatus may be used). The hand-held wand  156  is constructed in a similar manner as the hand-held wand  120  described above. The wand  156  may be manually operable and individually mobile. The hand-held wand  156  is attached to a storage box  158  via a signal path  160 , which may be a cable having a desired length. Storage box  158  is positioned on the rig floor  151  and serves as a receptacle to receive the hand-held wand  156  and the signal path  160  when the hand-held wand  156  is not in use. 
         [0158]    An electronic conversion package  162  communicates with a connector on the storage box  158  via signal path  164 , which may be an airway or a cable communication system so that the electronic conversion package  162  receives the signals indicative of the identification code stored in the identifier assemblies  112  and/or RFIDT&#39;s, which are read by the hand-held wand  156 . In response to receiving such signal, the electronic conversion package  162  converts the signal into a format which can be communicated an appreciable distance therefrom. The converted signal is then output by the electronic conversion package  162  to a buss  166  via a signal path  168 . The buss  166 , which is connected to a drilling rig local area network and/or a programmable logic controller (not shown) in a well-known manner, receives the converted signal output by the electronic conversion package  162 . 
         [0159]    The central computer  132  includes an interface unit  170 . The interface  170  communicates with the central computer  132  via a signal path  172  or other serial device, or a parallel port. The interface unit  170  may also communicates with the buss  166  via a signal path  173 . The interface unit  170  receives the signal, which is indicative of the unique identification codes and/or information read by the hand-held wand  156 , from the buss  166 , and a signal from a drilling monitoring device  174  via a signal path  176 . The drilling monitoring device  174  communicates with at least a portion of a drilling device  178  ( FIG. 5D ) via a signal path  179 . The drilling device  178  can be supported by the rig floor  151 , or by the drilling rig. The drilling device  178  can be any drilling device which is utilized to turn pieces  114  of oilfield equipment, such as drill pipe, casing (in casing drilling operations) or a drill bit to drill a well bore. For example, but not by way of limitation, the drilling device  178  can be a rotary table supported by the rig floor  151 , or a top mounted drive (“top drive”) supported by the drilling rig, or a downhole mud motor suspended by the drill string and supported by the drilling rig. Optionally, the drilling device  178  has at least one RFIDT  178   a  therein or thereon and an RFIDT reader  178   b  therein or thereon. The RFIDT reader  178   a  is interconnected with the other systems as is the reader  152 , e.g. via the signal path  173  as indicated by the dotted line  173   a.    
         [0160]    The drilling monitoring device  174  monitors the drilling device  178  so as to determine when the piece  114  or pieces  114  of oilfield equipment in the drill string are in a rotating condition or a non-rotating condition. The drilling monitoring device  174  outputs a signal to the interface unit  170  via the signal path  176 , the signal being indicative of whether the piece(s)  114  of oilfield equipment are in the rotating or the non-rotating condition. The central computer  132  may be loaded with a pipe and identification program in its oilfield equipment database which receives and automatically utilizes the signal received by the interface unit  170  from the signal path  176  to monitor, on an individualized basis, the rotating and non-rotating hours of each piece  114  of oilfield equipment in the drill string. 
         [0161]    For example, when the drilling device  178  is a downhole mud motor (which selectively rotates the drill string&#39;s drill bit while the drill string&#39;s pipe remains stationary), the central computer  132  logs the non-rotating usage of each piece  114  of the drill string&#39;s pipe. In the case where the drilling device  178  is the downhole mud motor, the central computer  132  has stored therein a reference indicating that the drilling device  178  is the downhole mud motor so that the central computer  132  accurately logs the non-rotating usage of each piece  114  of oilfield equipment included in the drill string that suspends the drilling device  178 . 
         [0162]      FIG. 5D  shows a system  250  according to the present invention for rotating pieces of drill pipe  114  which have at least one identifier assembly  112  and/or one RFIDT in a pin end (or box end, or both) recess according to the present invention to connect a pin connection  252  of the piece  114  to a box connection  254  of an adjacently disposed piece  114  in a well known manner. Each piece  114  may have an RFIDT in its pin end and/or box end. The system  250  includes a reader system  250   a  (shown schematically) for reading the RFIDT in the pin end recess prior to makeup of a joint.

Nos. 4,603,464; 4,348,920; and 4,765,401. The reader system  250   a  may be located at any appropriate location on or in the apparatus  250 . 
         [0163]    The apparatus  250  is supported on wheels  256  which engage tracks (not shown) positioned on the rig floor  151  for moving the apparatus  250  towards and away from the well bore. Formed on an upper end of the apparatus  250  is a pipe spinner assembly  258  (or tong or rotating device) for selectively engaging and turning the piece  114  to connect the pin connection  252  to the box connection  254 . Optionally the assembly  258  has an RFIDT reader  258   a . An optional funnel-shaped mudguard  260  can be disposed below the pipe spinner assembly  258 . The mudguard  260  defines a mudguard bore  262 , which is sized and adapted so as to receive the piece  114  of oilfield equipment therethrough. The apparatus  250  also may include a tong or a torque assembly or torque wrench  263  disposed below the pipe spinner assembly  258 . An opening  264  is formed through the mudguard  260  and communicates with a mudguard bore  262 . Optionally an oilfield equipment identifying apparatus  110  includes a fixed mount reader  266  for automating the reading of the RFIDT&#39;s and of the identifier assemblies  112 , rather than the hand-held wand  156 . In one embodiment a flange  268  is located substantially adjacent to the opening  264  so as to position the fixed mount reader  266  through the opening  264  whereby the fixed mount reader  266  is located adjacent to the piece  114  of oilfield equipment when the piece  114  of oilfield equipment is moved and is being spun by the pipe spinner assembly  258 . The reader(s) of the apparatus  250  are interconnected with an in communication with suitable control apparatus, e.g. as any disclosed herein. In certain aspects, the fixed mount reader  266  can be located on the apparatus  250  below the pipe spinner assembly  258  and above the torque assembly or torque wrench  263 , or within or on the spinner assembly  258 ; or within or on the torque wrench  263 .

Hook  428  is used to attach kelly  432  to traveling block  422  during drilling operations, and elevators  430  are used to attach drill string  434  to traveling block  422  during tripping operations. Shown schematically the elevator  430  has an RFIDT reader  431  (which may be any reader disclosed or referred to herein and which is interconnected with and in communication with suitable control apparatus, e.g. as any disclosed herein, as is the case for reader  439  and a reader  444 . Drill string  434  is made up of a plurality of individual drill pipe pieces, a grouping of which are typically stored within mast  412  as joints  435  (singles, doubles, or triples) in a pipe rack. Drill string  434  extends down into wellbore  436  and terminates at its lower end with bottom hole assembly (BHA)  437  that typically includes a drill bit, several heavy drilling collars, and instrumentation devices commonly referred to as measurement-while-drilling (MWD) or logging-while-drilling (LWD) tools. A mouse hole  438 , which may have a spring at the bottom thereof, extends through and below rig floor  416  and serves the purpose of storing next pipe  440  to be attached to the drill string  434 . With drill pipe according to the present invention having an RFIDT  448  in a pin end  442 , an RFIDT reader apparatus  439  at the bottom of the mouse hole  438  can energize an antenna of the RFIDT  448  and identify the drill pipe  440 . Optionally, if the drill pipe  440  has an RFIDT in a box end  443 , an RFIDT reader apparatus can energize an antenna in the RFIDT  446  and identify the drill pipe  440 . Optionally, the drill bit  437  has at least one RFIDT  437   a  (any disclosed herein) (shown schematically). Optionally, or in addition to the RFIDT  448 , the drill pipe  440  has one or more RFIDT&#39;s  448   a  affixed exteriorly to the drill pipe  440  (see, e.g.,  FIGS. 25 ,  26 ) under wrap layers  448   b.    
         [0175]    During a drilling operation, power rotating means (not shown) rotates a rotary table (not shown) having rotary bushing  442  releasably attached thereto located on rig floor  416 . Kelly  432 , which passes through rotary bushing  442  and is free to move vertically therein, is rotated by the rotary table and rotates drill string  434  and BHA  437  attached thereto. During the drilling operation, after kelly  432  has reached its lowest point commonly referred to as the “kelly down” position, the new drill pipe  440  in the mouse hole  438  is added to the drill string  434  by reeling in drill line  418  onto rotating drum  426  until traveling block  422  raises kelly  432  and the top portion of drill string  434  above rig floor  416 . Slips  445 , which may be manual or hydraulic, are placed around the top portion of drill string  434  and into the rotary table such that a slight lowering of traveling block  422  causes slips  444  to be firmly wedged between drill string  434  and the rotary table. At this time, drill string  434  is “in-slips” since its weight is supported thereby as opposed to when the weight is supported by traveling block  422 , or “out-of-slips”. Once drill string  434  is in-slips, kelly  432  is disconnected from string  434  and moved over to and secured to new pipe  440  in mouse hole  438 . New pipe  440  is then hoisted out of mouse hole  438  by raising traveling block  422 , and attached to drill string  434 . Traveling block  422  is then slightly raised which allows slips  445  to be removed from the rotary table. Traveling block  422  is then lowered and drilling resumed. “Tripping-out” is the process where some or all of drill string  434  is removed from wellbore  436 . In a trip-out, kelly  432  is disconnected from drill string  434 , set aside, and detached from hook  428 . Elevators  430  are then lowered and used to grasp the uppermost pipe of drill string  434  extending above rig floor  416 . Drawworks  424  reel in drill line  418  which hoists drill string  434  until the section of drill string  434  (usually a “triple”) to be removed is suspended above rig floor  416 . String  434  is then placed in-slips, and the section removed and stored in the pipe rack. “Tripping-in” is the process where some or all of drill string  434  is replaced in wellbore  436  and is basically the opposite of tripping out. In some drilling rigs, rotating the drill string is accomplished by a device commonly referred to as a “top drive” (not shown). This device is fixed to hook  428  and replaces kelly  432 , rotary bushing  442 , and the rotary table. Pipe added to drill string  434  is connected to the bottom of the top drive. As with rotary table drives, additional pipe may either come from mouse hole  438  in singles, or from the pipe racks as singles, doubles, or triples. Optionally, drilling is accomplished with a downhole motor system  434   a  which has at least one RFIDT  434   b  (shown schematically in  FIG. 12A ). 
         [0176]    As shown in  FIG. 12B , the reader apparatus  439  is in communication with a control apparatus  449  (e.g. any computerized or PLC system referred to or disclosed herein) which selectively controls the reader apparatus  439 , receives signals from it and, in certain aspects, processes those signals and transmits them to other computing and/or control apparatus. Similarly when the optional reader apparatus  444  is used, it also is in communication with the control apparatus  449  and is controlled thereby. With a reader at the pin end and a reader at the box end, the length of the piece of drill pipe be determined and/or its passage beyond a certain point. In one aspect the reader apparatus  439  is deleted and the reader apparatus  444  reads the RFIDT (or RFIDT&#39;s) in and/or on the drill pipe  440  as the drill pipe  440  passes by the reader apparatus  444  as the drill pipe  440  is either lowered into the mouse hole  438  or raised out of it. The reader apparatus  444  may be located on or underneath the rig floor  416 . It is within the scope of the present invention to use a reader apparatus  439  and/or a reader apparatus  444  in association with any system&#39;s mouse hole or rat hole (e.g., but not limited to, systems as disclosed in U.S. Pat. Nos. 5,107,705; 4,610,315; and in the prior art cited therein), and with so-called “mouse hole sleeves” and mouse hole scabbards” as disclosed in, e.g. U.S. Pat. Nos. 5,351,767; 4,834,604; and in the prior art references cited in these two patents. With respect to the drilling operation depicted in  FIG. 12A  (and, any drilling operation referred to herein according to the present invention) the drilling may be “casing drilling” and the drill pipe can be casing.

It is within the scope of the present invention to provide, optionally, reader apparatuses (E.G. other than adjacent the pipe or adjacent a mouse hole, or tubular preparation hole)  453  and/or  459  on the rig  452 . Optionally, one or more antenna energizers are provided on a rig and reader apparatuses are located elsewhere. According to the present invention a scabbard can be made of nonmagnetic metal, plastic, polytetrafluoroethylene, fiberglass or composite to facilitate energizing of an RFIDT&#39;s antenna of an RFIDT located within the scabbard. Optionally a scabbard may be tapered to prevent a pipe end from contacting or damaging the reader apparatus  456  and/or, as shown in  FIG. 13B , stops  454   a  may be provided to achieve this. 
         [0178]    Various prior art systems employ apparatuses known as “powered mouse holes” or “rotating mouse hole tools”.
