Stanfield A. V. #4 (API 42-115-32157) is a well in Dawson County operated by Legacy Reserves Operating LP, completed January 31, 1985.
The RRC has issued one drilling permit, issued December 19, 1984, permitted to 8,100 ft.
It was permitted by Conoco Inc. and has since transferred to Legacy Reserves Operating LP on the wellbore schedule.
Completion filings report one formation top, including Spraberry.
Its 2 leases have reported 2.11M barrels of oil and 358K mcf of gas since January 1993, last reporting in July 2026. The leases carry 36 wells, so these are lease totals, not this well alone.
