Executive Summary
Several issues may arise during the wind down process that would require attention, which are analyzed as part of this project to generate reservoir engineering information and solutions that will allow SAGD operators to propose process options to the Alberta Energy Regulator (AER) after the economic life of SAGD operations. Left unattended, depleted SAGD reservoirs could
become thief zones for adjacent producing reservoirs, negatively affecting their performance and increasing associated greenhouse gas emissions.
This project looks at the Steam Assisted Gravity Drainage (SAGD) Wind Down process and identifies data gaps, through review of available and usable data, and summarizes newly generated laboratory data to fill the gaps initially identified.
