ABSTRACT:
Disclosed is a process whereby heavy, viscous crude oil may be produced from a hydrocarbon-bearing formation utilizing a jet pump without the problems associated with cavitation damage of the jet pump found in the prior art. The jet pump is operated with a power fluid comprising water and surfactant, the power fluid forming an emulsion with the heavy, viscous crude oil in the jet stream of the jet pump.
