Granbury C. B. #4
Polk County · Copeland Creek East field · NO Production · Vertical
Granbury C. B. #4 (API 42-373-30830) is a well in Polk County operated by Texas Operating Partners LLC, completed October 4, 1995 and listed as no production on the RRC schedule.
The RRC has issued one drilling permit, issued August 16, 1995, permitted to 4,000 ft.
It was permitted by Geo Engineering, Inc. and has since transferred to Texas Operating Partners LLC on the wellbore schedule.
Completion filings report one formation top, including Jackson.
Its lease has reported 223K barrels of oil and 120 mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Geo Engineering, Inc.; the EWA schedule now lists a different operator.
