Anadarko Basin maturity modeling study

This multiclient study has reconstructed the depositional, tectonic, erosional, and thermal history of the Anadarko Basin. It includes models for 80 wells distributed evenly across the basin. Particular attention was paid to creating fully integrated geologic models from the Cambrian to present day. Models were calibrated using log porosities, corrected wireline log temperatures, and thermal indicators, mainly Mean Ea and Ro. Hydrocarbon-generation history was calculated for eight different source rocks, and the potential for preserving hydrocarbons against cracking was examined in reservoirs of all ages.

This study, which has been completed and delivered, provides important new insights that will lead to reassessment of the thermal history and maturity levels for all source rocks in the basin. It will thus become an essential source of information for any company that wants to explore conventional or unconventional plays in the Anadarko Basin using the most-modern ideas and technologies.
