Abstract
A process for reducing pressure in a well for well kill, during and after recovery of hydrocarbons from a formation. A mobilizing fluid is injected through the well and into the formation to mobilize the hydrocarbons and increase the well pressure, followed by emulsion fluids production to surface while mobilizing fluid injection is discontinued, which decreases the well pressure in preparation for well kill. The emulsion fluids are directed to a produced emulsion line at a first pressure, with at least some of the emulsion fluids instead redirected to an additional line at a lower second pressure as well pressure decreases, and these fluids from the additional line are then pumped at a third pressure higher than the second pressure into the produced emulsion line.
