M.A.K.(Spraberry)Unit Swd #4402 (API 42-317-32916) is a well in Martin County operated by Rattler Midstream Operating LLC, completed November 23, 2022.
The RRC has issued 2 drilling permits between 1984 and 2019, permitted to 9,100 ft.
It was permitted by Diamondback E&P LLC and has since transferred to Rattler Midstream Operating LLC on the wellbore schedule.
Completion filings report 7 formation tops, including B/Santa Rosa, San Andres, Clear Fork, Spraberry.
Its 5 leases have reported 1.54M barrels of oil and 923K mcf of gas since January 1993, last reporting in July 2026. The leases carry 44 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 430K barrels injected in the 12 months reported through January 2026; TexNet located 22 M2+ earthquakes within 10 km over the last two years.
