Advanced Mud Gas Evaluation in a Complex Clastic Reservoir While Drilling in the Usano Field of PNG
February 2020, Papua New Guinea Geosciences Conference and Exhibition
This case study describes how the analysis of a range of hydrocarbon components enabled accurate reservoir zonation in an area of very complex geology. Specific proxies from the gas data were used to confirm fluid types and identify gas/oil/water contacts (GOC/OWC) in an environment where downhole tools failed to deliver definitive results.
