Patent ID: 7588080

Claim:
A method of installing downhole completion equipment in a well, comprising: (a) connecting an electrical line to the completion equipment; (b) lowering the completion equipment into the well and deploying the electrical line while the completion equipment is in a non operational state; (c) while the completion equipment is moving downward in the well and without causing the completion equipment to enter an operational state, at least periodically supplying test voltage to the electrical line and displaying a response to the application of test voltage at the surface to monitor the integrity of the completion equipment and the electrical line by measuring a resistance to ground of the electrical line; then (d) when at a desired depth, securing the completion equipment in the well and placing the completion equipment in an operational state; wherein step (b) comprises unwinding the electrical line from a reel; mounting a battery-powered test unit to the reel for rotation therewith and connecting a lead of the unit to the electrical line; and wherein step (c) comprises applying test voltage from and receiving the response with the unit.
