Abstract: A method of hanging a cable within a coiled tubing string includes the steps of determining a length of coiled tubing required within a well having a wellhead; determining a length of a cable required within the coiled tubing, the cable having a structural component along the length of the cable sufficient to support the weight of the cable; cutting the tubing string and installing a hanger sub in the coiled tubing string toward, the wellhead attachment section relative to the downhole end, the hanger sub comprising an inner shoulder that extends radially into the hanger sub and defines an opening; and attaching an outer shoulder to the cable and inserting the cable into the coiled tubing string until the outer shoulder of the cable engages the inner shoulder of the hanger sub such that the inner shoulder positions the cable below the outer shoulder.

Abstract: A fluid delivery system for an inverted electric submersible pump (ESP), where the ESP has a motor section positioned above a pump section in a production path of a hydrocarbon well. The system has a supply of fluid connected to the motor section of the ESP by a supply line and a positive displacement pump that pumps fluid through the supply line to the ESP. A valve is connected between the positive displacement pump and the ESP. The valve is in an open state when the positive displacement pump is pumping fluid. A bypass line is connected in parallel to the positive displacement pump and connected between the normally closed valve and the supply of fluid, the bypass line having a check valve that permits the flow of fluid from the supply of fluid to the ESP.
