Brazos County · Giddings (Buda) field · Horizontal
Granberry #6 (API 42-041-31897) is a plugged horizontal well in Brazos County, plugged May 6, 2008, last operated by Chaparral Energy L.L.C..
The RRC has issued 2 drilling permits (amended twice) between 1997 and 2009, permitted to 9,000 ft.
It was permitted by Northfield Enterprises, Inc. and has since transferred to Chaparral Energy L.L.C. on the wellbore schedule.
Completion filings report 3 formation tops, including Austin Chalk, Buda, Georgetown.
Its 2 leases have reported 175K barrels of oil and 192K mcf of gas since April 1997, last reporting in March 2025. The leases carry 2 wells, so these are lease totals, not this well alone.
