Cahill T. G. -B- #1 (API 42-135-08065) is a well in Ector County operated by Formentera Operations LLC, completed July 22, 1982 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 28, 1982, permitted to 9,360 ft.

It was permitted by Amoco Production CO.-Andrews and has since transferred to Formentera Operations LLC on the wellbore schedule.

Its lease has reported 198K barrels of oil and 390K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
