Gilliam C. J. #3 (API 42-197-30278) is a well in Hardeman County operated by EP Operating Company, completed August 4, 1978.
The RRC has issued 3 drilling permits between 1978 and 2010, permitted to 8,981 ft.
It was permitted by Cimarex Energy CO. and has since transferred to EP Operating Company on the wellbore schedule.
Completion filings report 4 formation tops, including Canyon, Chester, Meramec, Ellenburger.
Its 4 leases have reported 349K barrels of oil and 222K mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
