Vann D. M. #B8
Caldwell County · Buchanan field · Vertical
Vann D. M. #B8 (API 42-055-31355) is a well in Caldwell County operated by Cardozo Technologies Inc., completed July 14, 1987.
The RRC has issued one drilling permit, issued February 29, 1980, permitted to 2,800 ft.
It was permitted by International Western Oil Corp. and has since transferred to Cardozo Technologies Inc. on the wellbore schedule.
Its 2 leases have reported 5.2K barrels of oil and 486 mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by International Western Oil Corp.; the EWA schedule now lists a different operator.
