Perforation method and apparatus |
摘要 |
A signature element is attached to a downhole cable or other protected equipment and the signal from a signature position detector is used, at least in part, to control the orientation of a directed perforating device or other directional device. Signal emitting sources can include a radioactive material added to an encapsulating composition of a downhole cable.
