Abstract
A pump-through electrical conductor line includes an electrically conductive wire, an insulative coating disposed over the electrically conductive wire, and a tubing having the electrically conductive wire with the insulative coating disposed thereover loosely positioned therein so as to form a non-obstructed annulus between the insulative coating and an inner surface of the tubing. An arrangement for downhole casing collar location includes a length of the pump-through electrical conductor line, a slickline running unit configured to deliver the pump-through electrical conductor line to a downhole environment, a plugging device disposed on a downhole end of the pump-through electrical conductor line, and a casing collar locator disposed on the pump-through electrical conductor line adjacent the plugging device. The location of a casing collar involves running the casing collar locator on the pump-through electrical conductor line into the downhole environment and communicating with the casing collar locator through the electrically conductive wire of the pump-through electrical conductor line.
