Walling, J B

An improved system for lifting formation fluid from a well bore to a surface facility is disclosed. Rigid production tubing and sucker rods are replaced by flexible, composite production tubing in which a production conduit, power conductors, signal conductors, hydraulic/pneumatic conduits and a load-bearing tension member are enclosed by a flexible, tubular covering. The load-bearing member of the flexible production tubing is mechanically coupled to a submersible pump. The pump includes driving means such as an electrical motor, hydraulic motor or pneumatic motor which is driven downhole by electrical or hydraulic/pneumatic power transmitted through auxiliary conduits in the flexible production tubing. The flexible production tubing is wound about a truck-mounted reel for convenient transport to and from a well site. A submersible pump is attached to the end of the flexible tubing and is played out from the reel through the well casing to the producing formation. Withdrawal of the pump from the well is accomplished by taking up the flexible production tubing around the truck-mounted reel.
