Patent ID: 7255175

Claim:
A fluid recovery system for collecting formation fluid at the surface of a well, the well including an outer tubular, a production tubular positioned within the outer tubular, and an annulus between the outer tubular and the production tubular, the system comprising: a downhole jet pump including a fluid nozzle to convert pressure of the power fluid to velocity, an intake directing the formation fluid into a jet, a mixing tube for mixing the power fluid and the formation fluid, and a diffuser for converting the velocity of the mixed fluid to pressure; a diaphragm pump at the surface for powering the downhole jet pump, the diaphragm pump including a plurality of diaphragms for pressurizing the power fluid; a flow meter for measuring the quantity of power fluid from the diaphragm pump to the jet pump; and a pressure sensor for monitoring the pressure of the power fluid from the diaphragm pump to the jet pump.
