Brazos County · Giddings (Austin Chalk Gas) field · Horizontal
Mccullough-Mccullough A #1RE (API 42-041-31672) is a horizontal well in Brazos County operated by Union Pacific Resources Company, completed December 21, 1992.
The RRC has issued 2 drilling permits (amended once) between 1992 and 2009, permitted to 14,100 ft.
It was permitted by Enervest Operating, L.L.C. and has since transferred to Union Pacific Resources Company on the wellbore schedule.
Completion filings report 3 formation tops, including Midway, Pecan Gap, Austin Chalk.
Its 3 leases have reported 69.3K barrels of oil and 2.69M mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
