Abstract
A fluid recovery system 10 for collecting formation fluid at the surface of a well 12 includes a downhole jet pump 20 and a surface diaphragm pump 40 having a plurality of diaphragms 42. The jet pump includes a fluid nozzle 22, an intake 24 directing the formation fluid into a jet 26, a mixing tube 28 for mixing the power fluid and the formation fluid, and a diffuser 30 for converting the velocity of the mixed fluid to pressure. A flow meter 50 and a pressure sensor 52 monitor the quantity and pressure of the power fluid to the jet pump.
