Improving Fold and Thrust Belt Imaging, Wyoming Thrust Belt, Wyoming—A Case Study

The LaBarge area of the Wyoming Range is located along the western edge of the Green River Basin in westcentral<br>Wyoming. ExxonMobil’s predominantly gas and minor oil production from the LaBarge area began in<br>1953 from the Cretaceous Frontier Formation with additional production from the Mississippian Madison<br>Formation in the mid 1980’s. Methane gas production from these main producing intervals currently exceeds 200<br>Mcf/d from ExxonMobil leases. In 2004 ExxonMobil undertook a 4 year effort focused on improving seismic<br>imaging over the extensive LaBarge structure with the primary objective to improve understanding of the complex<br>structural framework and fault geometries that control productivity trends and to identify new opportunities on the<br>existing leases.
