During late-life phases of steam-assisted gravity drainage (SAGD) projects, noncondensable gas (NCG) and water breakthrough from thief zones of aquifer connectivity can leave pockets of bitumen untouched. This study integrates laboratory testing with reservoir simulation to evaluate the effectiveness of autonomous inflow control valves (AICVs) in managing late-life SAGD production challenges. The results highlight the potential of AICVs to mitigate production issues, optimize fluid regulation, and extend the productive life of SAGD wells.
Working Principles of the AICV
In 2012, the AICV was introduced, featuring a self-adjusting flow area that responds to both viscosity and density. The AICV shuts off automatically in the presence of 100% water or gas, enabling efficient reservoir drainage.
