A reprint of Formation Water Resistivities originally compiled by Don Cardinal (1984) is now available on the EORI website. This publication is a valuable resource for establishing Rw values necessary for calculating oil and water saturations from wireline logs. Data are compiled by basin and include: well name and location, formation, depth, source of the water, Shut-in-Pressure, and measured water resistivity.

Topics covered in this briefing:

• Ongoing Operator & Vendor Support
• WY Energy & Policy Insights
• Wyoming CO2-EOR Potential & Impact
• Impact of Electricity Costs on Oil/Gas Development
• Proposed Benchmarking

After several decades of decline Wyoming’s oil production is now turning higher thanks to higher oil prices, the development of condensates, and investments in tertiary methods such as CO2 Enhanced Oil Recovery (CO2-EOR). The present work brings together two prior pieces of research by integrating the economic impact model of Cook (2013a) with the scoping estimates of Wyoming’s CO2-EOR potential found in Cook (2013b). The hope is that discussing the potential economic contribution of CO2-EOR will help inform industry participants and policy makers for the further development of CO2 infrastructure in the state.

There are two main themes of this poster. The first theme is to provide an update on the stratigraphy and sedimentology of the Tensleep/Casper Formation of Southeast Wyoming (and parts of Northern Colorado), and oil production from these rocks. We incorporate new measured sections, stratigraphic analysis and petrographic work undertaken by the authors. To this end we created a new database in ArcGis (geographic information software) of tops and other information that updates the historical well database of the Wyoming Oil and Gas Commission archived in Casper. This new database has been used to create Common Risk Segment (CRS) maps of the Upper Tensleep oil play in Southeast Wyoming. These CRS maps indicate trends in Tensleep reservoir, charge and trap that are useful in planning further exploration. It is possible that use of advanced seismic techniques applied over the complex structural terrains in the identified high potential areas of SE Wyoming will produce new leads and ultimately, new discoveries.
