Mahoney H. O. #88 (API 42-501-34618) is a well in Yoakum County operated by Hilcorp Energy Company, completed November 13, 2009 and listed as shut in on the RRC schedule, shut in September 1, 2023.

The RRC has issued one drilling permit (amended once), issued August 9, 2001, permitted to 5,583 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 9 formation tops, including Rustler, Salado, Yates, Seven Rivers.

Its lease has reported 16.9M barrels of oil and 32.4M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 122 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

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