Application of Geostatistical Inversion in the Permian Basin
This Webinar will cover CGG Reservoir America's Geostatistical Inversion technology applied to a study aimed at characterizing the complex Wolfcamp geological transition between the Eastern Midland Basin platform (Glasscock Nose area) and the Midland basin to identify and target higher porosity reservoirs. The study area is located beneath the town of Big Spring in Howard County and utilized multiple data types ranging from cuttings to seismic. The combination of this data was used to obtain a reliable volume estimation of Carbonate and Shale variation in the Wolfcamp A and B. CGG’s geostatistical inversion approach was applied to generate Lithotypes probability, pseudo Vcalcite and Porosity at a finer scale (c. 8/10 ft), compared to traditional inversion techniques. The results were validated against lateral well data (data validation away from vertical well constraint) with a positive correlation observed and geobodies corresponding to the regional depositional architecture. The resulting volumes can be used to produce P10, P50 and P90 maps (porosity and calcite) to quickly identify lateral well targets at any level within the Wolfcamp Formation. Furthermore, the volume can be utilized in drill and completion plans to optimally place, space and complete current and future lateral wells.
