Mahaffey -B- #210 (API 42-431-31137) is a well in Sterling County operated by Eqt Production Texas LLC, completed June 15, 1982.
The RRC has issued one drilling permit, issued April 12, 1982, 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, Queen, Dean, Cisco.
Its 2 leases have reported 22.1K barrels of oil and 905K 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.
