White & Baker -S- #4 (API 42-371-35139) is a well in Pecos County operated by Acorn Oil & Gas LLC, completed October 9, 1984 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 14, 1984, permitted to 2,000 ft.
It was permitted by Helmerich & Payne, Inc. and has since transferred to Acorn Oil & Gas LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Queen, Grayburg.
Its lease has reported 23.5K barrels of oil and 6.86K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
