Abstract
A process for preparing a well for use in subsequent recovery of hydrocarbons from a hydrocarbon-bearing formation wherein (i) mobilizing fluid is injected into the formation and emulsion fluids are produced to surface and directed to a high-pressure produced emulsion line, reducing pressure in the well, (ii) mobilizing fluid injection is terminated while emulsion production continues at reduced pressure, (iii) redirecting a portion of the reduced-pressure emulsion fluids to an additional low-pressure line instead of the produced emulsion line, and (iv) pumping the portion of the emulsion fluids at an elevated pressure from the additional line into the produced emulsion line.
