Over the years , DOE / NETL has been on the fore front of developing new technologies which improve drilling efficiency . The outlet from the dip tube shall be not larger than a No. 54 drill size orifice . This will then join with the drilled incision through the rim . Drill core recovered from Site 1270 represents a typical example of completely serpentinized harzburgite . LWD and MWD systems increase drilling efficiency through smarter drilling and the smart pipe will allow for even for efficient drilling . NETL will continue to be a leader in new technology development for improved drilling efficiency through programs such as Deep Trek , Microhole Drilling and Effective Environmental Protection . The IADC document service offers a list of publications of interest to the drilling community . The DEP-device can be designed with the length of the mesuring electrode ranged about 10 mm and , if the device is operating as drill core detector , the length of the protective electrode ranged about 300 mm or , if the device is operating as drill hole probe , the length of the protective electrode to be the sixfold to the tenfold of that . If congruity was found between a lesion in a histological section of a flight mouse and a drill core in the corresponding control histological section , and if the lesion was consistent with current concepts of what a cosmic ray-induced lesion should look like-that is linear , or columnar or even spherical-there would be a high probability that the lesion was produced by the cosmic ray particle .
