Mahoney H. O. #64W (API 42-501-32860) is a well in Yoakum County operated by Hilcorp Energy Company, completed August 13, 2014 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits (amended once) between 1985 and 2014, permitted to 8,200 ft.

It was permitted by Xto Energy Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 10 formation tops, including Dewey Lake, Rustler, Salado, Yates.

Its 2 leases have reported 22.8M barrels of oil and 33.5M mcf of gas since January 1993, last reporting in July 2026. The leases carry 186 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.
