in one embodiment , the invention may be a method for recovering oil from a gas - lifted oil well penetrating a subterranean oil - bearing formation . for the purposes of this disclosure , the term gas lift means a method of recovering oil from an oil well wherein crude oil is converted into a foam and conveyed to the surface in form of foam . the gas for this method may be introduced by the well operator or may be already present naturally . examples of such naturally present gases are carbon dioxide and / or natural gas . the method of the disclosure may be used with any gas lift method known to be useful to those of ordinary skill in the art of producing oil . for example the method of the disclosure can be used with the gas lift method disclosed in u . s . pat . no . 5 , 871 , 048 to tokar , et al , which is fully incorporated herein by reference . in tokar , a method for automatically determining an optimum gas injection rate for a gas - lifted oil well is disclosed . the optimum gas - lift slope for the oil well is initially provided and stored in the memory of a programmable logic controller . a lift gas is injected into the well at an initial gas injection rate to displace a liquid at an initial liquid production rate from the well . the initial liquid production rate and initial gas injection rate are stored in the memory . thereafter , the lift gas is injected into the well at a first incremental gas injection rate differing from the initial gas injection rate by a first incremental value . additional liquid is displaced from the well at a first incremental liquid production rate and the first incremental liquid production rate and first incremental gas injection rate are stored in the memory . the first incremental slope is determined from the stored data points and compared to the optimum gas - lift slope . the procedure is repeated for a second incremental gas injection rate , wherein the second incremental value is selected as either positive or negative in response to the comparison of the first incremental slope and the optimum gas - lift slope . the second incremental slope is determined from the stored data points and compared to the optimum gas - lift slope . in response to this comparison , the first incremental gas injection rate is determined to be the optimum gas injection rate or the above - recited procedure is repeated for a third incremental gas injection rate and additional incremental gas injection rates , if necessary , until an incremental gas injection rate is determined to be the optimum gas injection rate . the method of the disclosure can also be used with less complex gas lift methods . the method of the disclosure may be used with any gas lift method as long as the gas lift method serves the functions of lifting formation fluids to the surface which then results in a lower pressure at the producing strata which in turn results in an increased inflow of formation fluids into the well bore . in all of these methods , the gas injection is done at a depth sufficient to lift formation fluid to the surface and allow for the inflow of additional formation fluid into the well bore . any combination equipment and methods can be used with the method of the disclosure as long as it meets these two basic criteria . in another embodiment , the method for recovering oil from a gas - lifted oil may include a step of injecting a lift gas into the oil well . any lift gas known to be useful to those of ordinary skill in the art of using gas lift recovery methods can be used with the method of the disclosure . one gas commonly used as a lift gas with the method of the disclosure is natural gas , preferably that recovered from the same formation as the well subject to the gas lift method . other gases can also be used including those selected from the group consisting of carbon dioxide , methane , ethane , propane , nitrogen , and mixtures thereof . any gas that is not detrimental to the formation , such as oxygen , can be used with the method of the disclosure . in yet another embodiment , the method of the disclosure is a method for recovering oil from a gas - lifted oil well including the step of injecting a surfactant into the oil well . the surfactants useful with the method of the disclosure function to reduce the surface tension between the lift gas and the formation fluid being lifted to the surface and / or create a foam of the lift gas and the formation fluid . this decreased surface tension and / or foam formation allows for a decrease in the density of the formation fluid which results in an increase in lift efficiency . the method of the disclosure is directed towards the unloading of crude oil from an oil well . this is distinguished from unloading brine and / or condensate from gas wells . the crude oil that is unloaded using the method of the disclosure may have an api gravity of less than or equal to 45 . the surfactants useful with the invention of the disclosure include a silicone resin . silicone resins are highly crosslinked polymeric siloxane systems . the crosslinking is introduced through the incorporation of trifunctional and tetrafunctional silanes with monofunctional or difunctional , or both , monomer units during manufacture of the silicone resin . as is well understood in the art , the degree of crosslinking that is required in order to result in a silicone resin will vary according to the specific silane units incorporated into the silicone resin . in general , silicone materials which have a sufficient level of trifunctional and tetrafunctional siloxane monomer units ( and hence , a sufficient level of crosslinking ) such that they dry down to a rigid , or hard , film are considered to be silicone resins . the ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a particular silicone material . silicone materials which have at least about 1 . 1 oxygen atoms per silicon atom will generally be silicone resins as used herein . in some embodiments , the ratio of oxygen : silicon atoms is at least about 1 . 2 : 1 . 0 . silanes used in the manufacture of silicone resins include monomethyl -, dimethyl -, monophenyl -, diphenyl -, methylphenyl -, monovinyl -, and methylvinyl - chlorosilanes , and tetra - chlorosilane , with the methyl - substituted silanes being most commonly utilized . one silicone resin useful with the method of the disclosure is marketed under the trade designation dow corning 1250 . this resin has a molecular weight of about 5770 and mn of about 3160 . such commercially available silicone resins will generally be supplied in an unhardened form in a low viscosity volatile or nonvolatile silicone fluid . the surfactant may be introduced downhole in combination with a diluent . the diluents may function to decrease the concentration of the silicone resin for easier dispersion within the wellbore . more importantly , the diluents also functions to vaporize slowly in the wellbore to facilitate greater foam production . the diluents are selected to be compatible with silicone resin and any other components present with the resin at the time of injection downhole . exemplary diluents include , but are not limited to , diesel oil , xylenes , toluene , kerosene , gasoline and the like and combinations thereof . the method of the disclosure may reduce the cost of recovery of oil from a gas - lift oil well in at least two ways . a first way that the costs can be reduced in recovering oil from a well wherein the rate of recovery is limited by the amount of gas that can be injected , is by increasing the amount of formation fluids being recovered per unit of gas used . with the method of the disclosure , oil may be recovered more quickly reducing the duration of the maintaining the well with its incumbent costs . a second way that the method of the disclosure can reduce production costs is , in a well wherein the rate of recovery in not limited by the amount of gas which can be injected , is by reducing the amount of gas which must be injected . since the lift gas lifts more efficiently , less gas is needed to lift the same amount of formation fluids as compared to a conventional gas lift well operation . particularly in applications wherein there is not sufficient gas available from the formation being produced and other gasses such as nitrogen or carbon dioxide is being purchased , this can result in a substantial savings as compared to conventional gas lift technology . for purposes of the present application , the term formation fluids means those fluids produced from a oil bearing subterranean formation including but not limited to oil , natural gas , water and the like . crude oil means formation fluids that include oil , condensate , and the like . in addition to decreasing the surface tension between the formation fluid and lift gas , the surfactants useful with the method of the disclosure are desirably non - corrosive . the surfactant formulations useful with the method of the application may include solvents . if used , it may be desirable to use solvents that do not strip off at the formation temperature or well operating temperature . failure to use such surfactants may leave residue on the gas lift system possibly choking the system . in applications of the method of the disclosure , the surfactant may be formulated using solvents which will not leave residue on the gas lift system . one advantage of using a solvent is that it can be used to mitigate premature vaporization of the diluents . a lower boiling diluent , such as toluene , can be injected with a higher boiling solvent , such as naphtha , resulting in a admixture that can be injected into an oilwell that would be to hot for the use of toluene diluents alone . in addition to silicone resins , other surfactants may be used in combination with the silicone resins . preferably , such surfactants used with the method of the disclosure are thermally stable at the formation temperature or well operating temperature of the well being treated . failure to use such surfactants can lead to the loss of efficiency of the gas lift system as the surfactants break down . surfactant break down products can also cause problem downstream . as such temperatures can exceed 250 ° f . ( 121 ° c .) and even reach 300 ° f . ( 149 ° c .) and above , it is desirable that for very high temperature environments , the surfactant be a sultaine or a hydroxy sultaine or salt there of . when the surfactant is a sultaine salt , it preferably has the general formula : rconh ( ch 2 ) m n + ( ch 3 ) 2 ch 2 ch ( oh ) so 3 − wherein r is a hydrocarbon side chain , and m varies from 1 - 100 . the counter ion may be any including na +, k + and the like . when the surfactant is a hydroxy sultaine salt thereof , it preferably has the general formula : rconh ( ch 2 ) m n + ( ch 3 ) 2 ch 2 ch ( oh ) ch 2 so 3 − where r is as previously defined . the counter ion may be any including na +, k + and the like . the hydrocarbon side chains designated as r in the above general formulae are , in some embodiments , aliphatic linear or branched chains having from 2 to 20 carbons . in some embodiments , the side chains are linear alkanes have from 10 to 16 carbons . in one embodiment , the side chain is a lauryl ( c 12 ) group . the surfactants useful with the invention may also include , but are not limited to betaines , organic phosphonates , alkyl sulfonates , and the like . any surfactant that is compatible with a system including a silicone resin , a diluent , and optionally a solvent may be used with the method of the disclosure . such surfactants as may have a synergistic effect with the silicone resins may be especially desirable . those of ordinary skill in art of performing gas lift operations on oil wells know how to determine the desired level of surfactants to be used with embodiments of the invention . for example , in one embodiment , the operator may elect to start feeding a fixed amount of surfactant and then , by trial and error , make adjustments to optimized feed levels in view of changes to production rates . in other embodiment , the operator of the well may choose to perform a test modeling his well in order to predict an optimum feed rate . variables associated with an oil well that may affect dosing levels of the additives may include the type of hydrocarbon being produced , the quantity of hydrocarbon being produced , the quantity of brine present in the production fluid , the presence of inorganic materials in the brine , the pressure of the reservoir , the amount of gas that can be injected down hole , and the like . where , in the practice of the method of the disclosure , the surfactants function to create a foam , it is sometimes desirable to break the foam after it is recovered from the well . the term “ breaking a foam ”, for the purposes of the disclosure , means to separate the gaseous component of the foam from the liquid component . any method known to be useful to those of ordinary skill in the art of breaking foams may be used with the method of the disclosure , including both chemical and mechanical methods . the following example is provided to illustrate certain embodiments of the disclosure . the example is not intended to limit the scope of the method of the disclosure and should not be so interpreted . amounts are in weight parts or weight percentages unless otherwise indicated . the foaming tests were conducted using a sample of 25 gravity raw crude oil . the general procedure used to conduct these foaming tests was as follows : 2 ) add 20 μm of crude , then specified foamer , followed by diluent . 3 ) reweigh tube to get initial wt . and measure height with a ruler in cm . 4 ) place tubes vertically individually in 38 ° c . water bath with a 70 rpm orbital shake for at least 15 minutes . 5 ) remove tubes individually and sparge with methane at 3100 ml / min for 3 minutes with tubes placed vertically into a beaker to capture any foam - over . 6 ) measure total height ; if foam has risen above the top of the tube ( foam - over ), record as 25 cm height and record time to foam - over . 7 ) for tubes with foam - over , carefully remove sparger scraping off as much foam as possible from sparger into tube . 8 ) for tubes with foam - over , wipe off outside to remove any foam sticking to tubes and reweigh ; record this as the final weight . the silicone resin used is dow corning 1250 . this material is characterized as a polytrimethylhydrosilylsiloxane . the diluent is xylenes . the data for this example is shown below in the table .
