METHOD FOR PRODUCING VISCOUS WELL FLUID FROM A FORMATION IN A HIGH TEMPERATURE ENVIRONMENT

摘要

A method utilizes artificial lift techniques to produce viscous well fluid from a formation in a high temperature environment. Diluents mix with the well fluid to power the artificial lift and may cool the well fluid for recovery to surface. The diluents provide viscosity reduction for the well fluid even though cooled, which thereby limits thermal cycling and integrity problems.
