Newberry #4HR (API 42-041-31377) is a horizontal well in Brazos County operated by Wildfire Energy Operating LLC, completed August 18, 1995.
The RRC has issued 4 drilling permits (amended twice) between 1986 and 2010, permitted to 11,000 ft.
It was permitted by Anadarko E&P Company LP and has since transferred to Wildfire Energy Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Austin Chalk, Top Of Chalk, A Marker, Base Of Chalk.
Its 3 leases have reported 357K barrels of oil and 573K mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
