ABSTRACT:
An apparatus for recovering fluid from a liquid formation includes a submersible pump for pumping fluid from the liquid formation. The submersible pump is coupled to an eductor defining a fluid member for receiving and transporting the fluid from the pump, and a fluid inlet in fluid communication with the fluid member for placement at a liquid-product layer in the formation. A probe assembly is coupled to the eductor for ensuring that the pump is inoperative when the fluid level in the formation is low. In operation, a motive force created by the upward flow of fluid pumped through the fluid member draws additional fluid into the fluid inlet from the liquid-product layer. The fluid entering the fluid inlet merges with the fluid flowing through the fluid member and is transported to a treatment facility. The recovery apparatus can further include an external fluid member coupled from the pump for receiving a portion of the fluid recovered by the pump and diverting it away from the eductor to the treatment facility.
