Paper presented at the SEG/AAPG International Meeting for Applied Geoscience & Energy, August 26–29, 2024
Paper Number: SEG-2024-4100677
... The upstream oil and gas sector faces the dual challenge of rapidly simulating large ensembles for history matching, sensitivity analysis, and project optimization, while simultaneously requiring high-fidelity to capture complex processes like EOR and CCS. To address these challenges efficiently...
