Limestone County · Farrar SE (Pettit) field · SWR-10-Well · Vertical
Jeff Thomas Gas Unit NO. 1 #4 (API 42-293-31079) is a well in Limestone County operated by Hilcorp Energy Company, completed June 3, 2011 and listed as swr-10-well on the RRC schedule.
The RRC has issued 2 drilling permits between 1994 and 2011, permitted to 9,806 ft.
It was permitted by Xto Energy Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 5 formation tops, including Massive Anhy, Rodessa, James Lime, Pettit.
Its 2 leases have reported 16.4K barrels of oil and 3.56M mcf of gas since January 1995, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
