Society of Independent Earth Scientists (SIPES) – Fort Worth Chapter
Petroleum Club of Forth Worth
777 Main Street
Fort Worth, TX 76102
Peter Wang, Geophysical Technical Advisor at Emerson E&P Software, will be the guest speaker at the monthly luncheon of the Society of Independent Earth Scientists (SIPES) – Fort Worth Chapter, with special co-presenter Monte Meers, Independent Geologist and Vice-Chair of SIPES Ft. Worth.   

Peter and Monte will present a case study, Exploring for Wolfcamp Reservoirs, Eastern Shelf of the Permian Basin, Texas, Using a Machine Learning Approach, co-authored by Bruno de Ribet (Emerson E&P Software), Howard “Pete” Renick (Independent Geologist), Russ Creath (Reservoir Geophysicist, Hardin International), and Ryan McKee (Geophysical Technician, RAM Imaging Technology).

One of the leading challenges in hydrocarbon exploration and production is predicting rock types and fluid content distribution throughout the reservoir away from the boreholes.  In this presentation, we will demonstrate the application of a neural network-based machine learning methodology called Democratic Neural Network Association (DNNA) to the problem of finding oil-filled packstones in the Middle Wolfcamp, Eastern Shelf of the Permian Basin, Texas.

The DNNA algorithm searched through fifteen 3D seismic volumes simultaneously, and was able to build a model which reconstructed the nine lithofacies. No evidence was seen of false positive or false negative predictions at the wells for the oil-filled packstone facies.

The neural network learnings were applied through the 3D survey, and results were delivered with up to a 0.5 ms two-way time vertical resolution, or about 5 ft, a significant uplift from conventional seismic resolution. Lateral resolution was also improved. Additional drilling opportunities can be identified from the seismic facies thickness map or the facies probability voxel clouds.
