A METHOD FOR ACCELERATING START-UP FOR STEAM ASSISTED GRAVITY DRAINAGE OPERATIONS

摘要

The present embodiment discloses a method for decreasing the time required for a start--up phase in a steam assisted gravity drainage production. The present method describes forming a steam assisted gravity drainage production well pair within a formation comprising an injection well and a production well, beginning a preheating stop by introducing heat between the injection well and the production well, beginning a steam squeeze stage by injection steam into the formation and beginning the steam assisted gravity drainage production.
