Mcelroy Ranch CO. M #30 (API 42-461-33175) is a well in Upton County operated by Xto Energy Inc., completed December 8, 1991 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued September 27, 1991, permitted to 10,235 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Xto Energy Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Rustler, Yates, Clear Fork, Wolfcamp.
Its lease has reported 1.7M barrels of oil and 5.76M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
