Structural Restoration and Petroleum Systems Modeling of the Wyoming-Utah Thrust Belt

摘要

The resulting model provides detailed insight into the history of the petroleum systems in the area, with a special focus on the La Barge and Tip Top gas fields near the eastern margin of the Wyoming-Utah thrust belt. Several petroleum systems, and a source of CO2, occur stacked in this area. Detailed migration simulations with source rock tracking revealed that the occurrence of gas and condensate can only be explained with the presence of very effective sealing lithologies.
