Abstract
A power delivery system for a wireline tool includes two independent power transmission loops operating on a standard six-conductor cable. The two loops each connect directly to a respective terminals of a DC auxiliary power supply. Each loop also couples through a transformer to an AC instrument power supply. Another transformer for telemetry signals facilitates bidirectional communication between the downhole tool and an uphole computer.
