Abstract
A process for workover of a hydrocarbon recovery well, wherein hydrocarbons are mobilized and well pressure increased by steam injection, the hydrocarbons produced to surface in emulsion fluids. The emulsion fluids are directed into a produced emulsion line at surface at a first pressure, steam injection is then discontinued into the well while continuing emulsion production at reduced pressure, at least some of the emulsion fluids are redirected to an additional line at a second pressure lower than the first pressure as pressure in the well decreases, the emulsion fluids are pumped from the additional line into the produced emulsion line at a third pressure higher than the second pressure, and a well kill fluid is injected into the well to allow the workover after the well pressure decreases.
