Martin County · Spraberry (Trend Area) field · Shut IN  · Horizontal

George Washington Wolcott (AJ) #3LL (API 42-317-42442) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed August 19, 2020 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued July 22, 2019, permitted to 10,000 ft.

It was permitted by Guidon Energy Mgmt Services LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Santa Rosa, Yates, Queen, Grayburg.

Its lease has reported 2.52M barrels of oil and 4.7M mcf of gas since November 2019, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
