Reagan County · Spraberry (Trend Area) field · Shut In · Vertical
Weatherby 1228 #4 (API 42-383-35278) is a well in Reagan County operated by De Central Operating LLC, completed April 4, 2003 and listed as shut in on the RRC schedule, shut in April 1, 2020.
The RRC has issued one drilling permit, issued January 2, 2003, permitted to 8,500 ft.
It was permitted by Tamarack Petroleum Company, Inc. and has since transferred to De Central Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.
Its 2 leases have reported 139K barrels of oil and 670K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
