Unconventional Najmah Reservoir Formation Evaluation in West Kuwait Using an Innovative-Integrated Approach for Productivity and Potential

Abstract

Abstract Abduliyah field is one of the major fields in the West Kuwait asset where the Najmah shale (Kerogen unit) is present. The Najmah shale is a high Kerogen content, calcareous mudstone and is considered the main source rock for shallower depth oil reservoirs in Kuwait, due to the shortage of data especially core data at reservoir condition there is enormous uncertainty in the determination of the unconditional reservoir properties that need to be evaluated to confirm both economic and operational success. An integrated logging approach was implemented using pressurized sidewall rotary coring, magnetic resonance, borehole image logs, conventional logs, and core analysis to assess the Najmah storage volume, and quantify the potential hydrocarbon fluids in place and provide a time and cost-efficient method of reservoir evaluation.
