Basin-wide modeling is utilized to improve confidence of source rock presence and quality estimation. A 4D basin model incorporates geological model, geochemical models, and resettlement model for a region. Utilizing the 4D basin model provides consistency of internal data, geology-constrained basin-wide calculations, capability to capture local controls to allow basin-specific interpretations, reduction of reliance on empirical relationships, and capability to investigate source rock development through time.
