Gilliam C. J. #4 (API 42-197-30312) is a plugged well in Hardeman County, plugged October 11, 2011, last operated by Assent Energy Partners LLC.
The RRC has issued one drilling permit, issued August 21, 1979, permitted to 9,000 ft.
It was permitted by Enserch Exploration, Inc and has since transferred to Assent Energy Partners LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Noble Lm, Canyon, Palo Pinto, Chester.
Its lease has reported 345K barrels of oil and 195K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
