Dawson County · Adcock (Spraberry) field · Vertical
Adcock #2 (API 42-115-31899) is a well in Dawson County operated by Brown Tom Inc., completed January 7, 1984.
The RRC has issued one drilling permit, issued November 8, 1983, permitted to 7,850 ft.
It was permitted by Cotton Petroleum Corp. and has since transferred to Brown Tom Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Spraberry, U. Spraberry, V. Spraberry (Vandivere Sd), L. Spraberry.
Its 2 leases have reported 357K barrels of oil and 13.5K mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
