The West Edmond Field is located in central Oklahoma and is one of the largest accumulations of Hunton Group oil in the Anadarko Basin. Oil and gas are stratigraphically trapped to the east against the Nemaha Ridge and to the north by a regional wedge-out of the group. Hunton Group reservoirs are the Bois d’Arc and Frisco Formations with some minor production from the Chimneyhill Limestone and Haragan and Henryhouse Formations. Field production exceeds 170 million barrels of oil (MMBO) and 390 billion cubic feet of gas (BCFG). Production from the Hunton Group in West Edmond Field exceeds 47 MMBO and 52 BCFG.

The reservoir characterization study of the Hunton Group in West Edmond Field is being carried out in conjunction with the petroleum systems-based assessment of oil and gas resources for the Anadarko Basin province. The Streeter 1 well, which is located in a West Edmond lease, is currently undergoing dewatering prior to gas production. We have examined and sampled core of this well in detail. Petrographic analyses of core samples will enable diagenetic relationships in the Hunton and associated controls on oil and gas to be determined, including potential hydrothermal alteration due to well proximity to the Nehama Ridge. This research will also be tied to timing of oil and gas generation and migration pathways.
