Mahoney H. O. #55 (API 42-501-31744) is a well in Yoakum County operated by Hilcorp Energy Company, completed August 8, 1990 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 13, 1979, permitted to 5,250 ft.
It was permitted by Mobil Oil Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its lease has reported 16.9M barrels of oil and 32.1M mcf of gas since January 1993, last reporting in July 2026. The lease carries 122 wells, so these are lease totals, not this well alone.
