An integrated geoscience workflow to improve unconventional play assessment – an example from the SCOOP/STACK, Oklahoma

Back to Technical Content
This article highlights some important outcomes from an integrated study in the Anadarko Basin. Newly generated data is presented and discussed across the study area. The main aspects discussed here focus on 1) basin evolution, which has played an important role in source maturity and hydrocarbon generation. 2) Source rock characterization, including source rock properties and quantification of the hydrocarbon content performed with a newly developed pyrolysis method and 3) reservoir characterization based on the integration of regional information and data generated from seismic reservoir characterization. These aspects are discussed to assess their implications on hydrocarbon distribution within unconventional resources from Woodford and Mississippian section. In the last section of this article, we propose a play assessment workflow that could be applied to address uncertainties associated with these plays. This workflow comprises 1) a regional or basin-scale evaluation based on 3D petroleum system modelling (3D PSM) and 2) a more detailed evaluation based on the integration of seismic reservoir characterization into petroleum systems modeling on a local scale.
