Basin Temperature Models TGS has developed a new methodology for generating accurate Basin Temperature Models to support the exploration for shale gas. The workflow to develop the model consists of:
� Over 10,000 logs are indexed for bottom-hole temperature (BHT) values for a basin � A lithostratigraphic framework is generated for the basin � BHT values are spatially distributed within each litho-stratigraphic interval � A line is drawn tangent to the maximum offset BHT values for each interval � A function is applied to adjust the slope of the interval geothermal gradient based on depth and lithology � The temperature volume is constructed by stacking the interval geothermal gradient layers for the basin
Models have been built for the Delaware Basin, Midland Basin, Central Platform, Eagle Ford area, Powder River Basin, Las Animas Arch area, Mississippi Lime Play, Anadarko Basin, Utica area, Michigan Basin and Tuscaloosa Marine Shale. TGS will continue to develop models for several other areas, trends and basins (onshore US and Canada) in the next couple of years.
Deliverables A new temperature model can be built in approximately 12 weeks and includes the following:
� Indexed BHT, mud weight and elevation data for approximately 10,000 logs � A consistent set of litho-stratigraphic picks for approximately 2,000 wells � Depth temperature grids for each litho-stratigraphic surface � Temperature volumes for the basin � Reports
Models can be licensed under an addendum to clients via the LOG-LINE Plus!® Well Log Data Operating Agreement.
