Enhanced Oil Recovery in Canada using CO2 Injection
Increased oil recovery and benefited from regulatory incentivesUsing CO2 injection as an enhanced oil recovery technique not only improves oil production, but also provides a storage area for the CO2. A variety of government regulations and incentives exist in regards to CO2 capture and storage. For example, in 2009, the Alberta government, awarded $2 billion for carbon capture and sequestration (CCS) projects, including CO2 enhanced oil recovery, CO2 enhanced gas recovery (EGR), and CO2 sequestration projects. When we focus on Alberta in particular, there are a variety of sources and sinks which could be potential candidates for such projects.
A successful CO2 EOR project requires a pairing of a CO2 source with a sink. In order for this to be achieved, expertise and experience in the form of a suitable screen, needs to be applied. Gaffney, Cline & Associates has a unique workflow which has been used in various CCS studies. The workflow focuses on three specific parts: static, dynamic, and economic parameters. Specific criteria, such as Original Oil in Place (OOIP), depth, pressure, API, previous waterflood performance, recovery factor (RF), and others are carefully examined and ranked.
