Randall E. #42 (API 42-501-34023) is a well in Yoakum County operated by Hilcorp Energy Company, completed September 29, 1995.
The RRC has issued 2 drilling permits between 1995 and 2001, permitted to 9,700 ft.
It was permitted by Exxon Mobil Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 12 formation tops, including Rustler, Queen, San Andres, Glorieta.
Its 3 leases have reported 2.13M barrels of oil and 703K mcf of gas since January 1993, last reporting in July 2026. The leases carry 23 wells, so these are lease totals, not this well alone.
