Presentations from University of Wyoming Enhanced Oil Recovery Institute’s “Recovering Stranded Oil through Improved and Enhanced Oil Recovery Technologies” conference, Sep. 13-14, 2010, Jackson WY. A sampling of the topics follows:
Biello, D., “What Does Carbon Capture and Storage Look Like? “ Scientific American, April 7, 2009 http://www.scientificamerican.com/slideshow.cfm?id=what-does-carbon-capture-and-storage-look-like A field trip showing the process diagrams and physical layout of all aspects of several full scale CCS projects. Ferguson, R., Van Leeuwen, T., Kuuskraa, V.: “Storing CO2 with Enhanced Oil Recovery”, presented at the Seventh Annual Conference on Carbon Capture & Sequestration, Pittsburgh, PA, May 5-8, 2008. A recap, update and summary of the 12 Basin Studies performed by ARI for the DOE to assess the CO2 EOR potential of the U.S. Snitkin, C., “CO2 Transportation”, presented at the 2009 CO2 Flooding Conference, Midland, Texas, December, 2009. An overview of the engineering aspects, design and requirements for CO2 pipelines worldwide, both onshore and offshore, plus discussion of marine transport of CO2. Merchant, D.H., “Comparisons of Conventional CO2 WAG Injection Techniques used in the Permian Basin”, presented at the 2009 CO2 Flooding Conference, Midland, Texas, December, 2009. http://www.co2conference.net/presentations/2009CO2FloodingConference_MerchantConsulting.pdf The results of an economic and engineering analysis of the different methods of CO2 injection (Continuous CO2, Constant Water and Gas (WAG) with fixed CO2 slug size and water to gas ratio, Simultaneous WAG with hourly changes, and Tapered WAG with a gradually increasing water to gas ratio in each progressive slug). Trentham, R., “Residual Oil Zones – Phantom Discoveries and Completions”, presented at the 2009 CO2 Flooding Conference, Midland, Texas, December, 2009. http://www.co2conference.net/presentations/2009CO2FloodingConference_UTPB_Trentham.pdf The origin and distribution of Residual Oil Zones (ROZ) is discussed. ROZs occur when a change in the structure over geologic time allows formation water to displace oil, sweeping it much in the fashion of a waterflood. The remaining oil is producible with CO2 enhanced technology. Of the three ROZ types, it is believed that the Permian basin ROZ is the result of a hydrodynamic tilt, which is evidenced by a tilted oil-water contact. The ROZ is presently being developed in a number of Permian CO2 floods and as discussed by ARI in the reference section, the potential recovery is very significant. |
