Dean (Spraberry) Unit #1 (API 42-115-00853) is a well in Dawson County operated by Petx Operating LLC, completed September 9, 2002 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued September 12, 2000, permitted to 11,000 ft.
It was permitted by Trinity Operating & Prod., Inc. and has since transferred to Petx Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including San Andres, Clear Fork, Spraberry.
Its lease has reported 56.4K barrels of oil and 70 mcf of gas since October 2000, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 25.3K barrels injected in the 12 months reported through August 2025.
