Brown M. M. #1601
Martin County · Breedlove (Spraberry) field · Vertical
Brown M. M. #1601 (API 42-317-33957) is a well in Martin County operated by Roff Operating Company LLC, completed February 6, 1994.
The RRC has issued one drilling permit, issued December 15, 1993, permitted to 8,600 ft.
It was permitted by Socorro Exploration, Inc. and has since transferred to Roff Operating Company LLC on the wellbore schedule.
Completion filings report one formation top, including Spraberry.
Its 2 leases have reported 635K barrels of oil and 428K mcf of gas since February 1994, last reporting in July 2026. The leases carry 12 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 30.7K barrels injected in the 12 months reported through February 2026.
