Optimization of Solvent – Based Enhancements of Steam Assisted Gravity Drainage

Modern Steam Assisted Gravity Drainage (SAGD) technology has proven its efficiency throughout the<br>world. However, sometimes steam generation by natural gas combustion can render the process<br>uneconomic. Moreover, ever-increasing environmental concerns and green house gases emission s<br>restrictions require further improvement of the existing technology. In addition to overcoming<br>environmental issues, operators are also interested in improving SAGD s performance in terms of daily<br>rates and recovery factors.
