PROCESS FOR PREPARING A WELL FOR A HYDROCARBON RECOVERY OPERATION

Abstract:

A process for preparing a well for use in recovery of hydrocarbons from a hydrocarbon-bearing formation is provided. The process includes injecting mobilizing fluid through the well and into the hydrocarbon-bearing formation, producing fluids from the hydrocarbon-bearing formation to a surface and directing the fluids into a produced emulsion line coupled to a facility for separation, discontinuing mobilizing fluid injection into the well for preparing the well for well kill, discontinuing directing produced fluids to the produced emulsion line and directing further produced fluids to an additional line as pressure in the well decreases, and pumping the further produced fluids from the additional line into the produced emulsion line for separation at the facility.
