Abstract
An apparatus, method, and system for use in operating an electric downhole tool on a non-conductive support line (slickline) by converting a battery voltage to an output voltage suitable for operating the tool. In response to receiving a trigger signal, the output voltage signal is applied to the tool. The tool is controlled by varying the output voltage signal according to a power control sequence. Accordingly, electric tools typically requiring surface intervention by an operator via an electric cable (wireline) may be operated on slickline.
