Assessment of Archie Parameters in Shale: An Experimental Approach

Abstract

Understanding the rock electrical-controlling factors is critical for well-log interpretation in shale formations. However, formation electrical models applying on the well-log interpretation for conventional reservoirs have proven not accurately transferable for shale formations due to the inaccurate selection of Archie’s parameters. This study provides recommended experimental procedures for the acquisition of Archie’s m, leading to improved accuracy for water saturation calculation from well-logs for shale reservoirs.
