Title: Gas injection to inhibit migration during an in situ heat treatment process

Patent ·
OSTI ID:1014726

Methods of treating a subsurface formation are described herein. Methods for treating a subsurface treatment area in a formation may include introducing a fluid into the formation from a plurality of wells offset from a treatment area of an in situ heat treatment process to inhibit outward migration of formation fluid from the in situ heat treatment process.
