Mahaffey -B- #110 (API 42-431-31067) is a well in Sterling County operated by Eqt Production Texas LLC, completed December 9, 1981.

The RRC has issued one drilling permit, issued November 6, 1981, permitted to 8,600 ft.

It was permitted by Wagner & Brown and has since transferred to Eqt Production Texas LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Yates, San Andres, Clear Fork, Cisco.

Its 2 leases have reported 22.1K barrels of oil and 799K mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
