Mullin W. W. #5 (API 42-345-30255) is a well in Motley County operated by Dry Fork Production CO. LLC, completed January 13, 1994 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued June 14, 1989, permitted to 9,500 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Dry Fork Production CO. LLC on the wellbore schedule.
Completion filings report 5 formation tops, including San Andres, Clear Fork, Abo Shale, Bursam Lime.
Its lease has reported 469K barrels of oil and 37.1K mcf of gas since January 1993, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
