..., causing it to sink, therefore, indefinitely containing the injected CO 2 and isolating it from potential interference with shallow aquifers or ultimately the atmosphere. Limitations (Economides and Xie, 2009): Injectivity loss. As CO 2 injection proceeds, the reservoir becomes more...

... of the technique resulted in the increase of the average measured net pressure from 14 to 27 bars at the end of the main treatment, indicating fracture containment within the pay zone. The contained fractures manifest a 4 times liquid and 3.2 times higher average oil production compared to the production before...
