Pecos County · Tunis Creek(devonian) field · Injection · Vertical
Tunis Creek Univ. Lands Unit #107 (API 42-371-35838) is a well in Pecos County operated by Basin Oil & Gas Operating LLC, completed March 27, 2002 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued April 25, 1986, permitted to 7,400 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yates, Queen, Grayburg, Wichita-Albany.
Its lease has reported 2.55M barrels of oil and 2.15M mcf of gas since January 1993, last reporting in July 2026. The lease carries 19 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 44.1K barrels injected in the 12 months reported through May 2025.
