Post Well Analysis (PWA)

Helping to Define Prospectivity and Understand Exploration Risk

TGS’ PWA provides an understanding of hydrocarbon potential and risks through the provision of historic analogs.

Exploration successes occur only when all critical factors, reservoir, seal, source and charge, are present.

TGS conducts a post drill analysis of exploration and appraisal wells. For each prospective level, irrespective of what was the primary target of the well, the analysis considers reservoir presence and quality, whether top seal and fault/side seal was effective, whether there was a valid trap and finally if the trap could have been charged.

All TGS PWA studies use all available data sources including composite logs, seismic data and TGS’ internal detailed geological, petrophysical and geophysical analysis collated in a geodatabase and delivered as a plug-in to TGS Facies Map Browser (FMB) or as a stand-alone product in ESRI ArcGIS.
