A hydraulic setting tool is shown of the type used to set a downhole device in a well bore. The setting tool includes an elongated tubular body adapted to be supported from a wireline within the well bore. The body has an outer sleeve portion and an inner piston portion slidably received within the sleeve portion. The inner piston portion and the outer sleeve portion are engagable with a device to be set whereby opposite relative movement of the piston portion and the sleeve portion acts to set the device. An electric motor is carried within the tubular body and is connected through the wireline with a source of electric power at the well surface. A hydraulic pump is carried within the tubular body having a fluid intake and a fluid output and is coupled to the electric motor to be driven thereby. A fluid passage communicates the hydraulic pump fluid output with the body inner piston portion for supplying pressurized hydraulic fluid to the inner piston portion to move the inner piston portion relative to the outer sleeve portion and thereby set the downhole device.
