Jeffreys #7 (API 42-399-33171) is a well in Runnels County operated by Tcs Petroleum CO. LLC, completed June 22, 1984 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 19, 1984, permitted to 4,000 ft.
It was permitted by Nordic Petroleums, Inc. and has since transferred to Tcs Petroleum CO. LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Dog Bend, U/Capps, L/Capps, Caddo.
Its lease has reported 19.8K barrels of oil and 196K mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
