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.

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.

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.
