Abstract:
A method for accelerating start-up for steam assisted gravity drainage operations comprising the steps of: forming a steam-assisted gravity drainage production well pair comprising an injection well and a production well within a formation; beginning a pre-soaking stage by soaking one or both of the wellbores of the well pair with a solvent; beginning a pre-heating stage by heating the wellbores of the well pair; beginning a squeezing stage by injecting steam into the wellbores of the well pair; and beginning steam-assisted gravity drainage production.
