Abstract:
Selectively automating the powering of downhole equipment during run-in-hole (RIH) operations provides a means of safely installing and monitoring downhole equipment. Selective automation comprises monitoring lowering of a pump assembly into a borehole as part of an installation process. In response to determining that the lowering of the pump assembly into the borehole has stopped, an output of power from a power source to a cable coupled to the pump assembly is allowed. A data transmission is communicated from a downhole gauge in the pump assembly to a communication device at a surface of the borehole via the cable. In response to not receiving a valid data transmission at the communication device, it is determined that the cable may be damaged, and that further cable testing should occur.
