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.

• Data Driven Reservoir Management
• Development of a Fully Compositional Model for Timber Creek
• Impact of Primary Strata on Recovery Factors in Aeolian
• Systems
• Wertz Tensleep

This study will seek a methodology to improve (a) accuracy in estimates of oil recovery factors and (b) planning field development including well spacing and arrangement. Further, we will create and apply laboratory measurements to understand movement of petroleum fluids at small scales in order to better evaluate upscaling techniques and verify the underlying assumptions of previous works. The proposed study has the potential to impact reserves estimates and production in Wyoming, because it addresses phenomena that constitute bulk properties of all eolian reservoirs in Wyoming and their remaining reserves along with new fields that may be discovered in eolian system rocks such as the Tensleep, Minnelusa, Leo, and Navajo Sandstones.
