Abstract
An electro-hydraulic well tool actuator is provided to control fluid-actuated well tools. The actuator may include a cylindrical housing at least one hydraulic fluid flowpath within the housing, a communication link sealably connected to the housing on one end and a control panel located at the earth's surface on the other, at least one solenoid valve mounted in the housing for directing the flow of hydraulic fluid, and at least one discharge port in the housing for delivering pressurized hydraulic fluid to a hydraulically actuated downhole device. Alternate embodiments include an onboard hydraulic system, and different methods of interfacing with downhole fluid actuated devices.
