Riverside Campus #1
Brazos County · Giddings (Austin Chalk-3) field · Horizontal
Riverside Campus #1 (API 42-041-31502) is a plugged horizontal well in Brazos County, plugged January 30, 2025, last operated by E2 Operating LLC.
The RRC has issued one drilling permit (amended once), issued May 3, 1991, permitted to 8,500 ft.
It was permitted by Ultramar Oil And Gas Limited and has since transferred to E2 Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Austin Chalk.
Its 2 leases have reported 467K barrels of oil and 2.28M mcf of gas since January 1993, last reporting in September 2025. The leases carry 7 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Ultramar Oil and Gas Limited; the EWA schedule now lists a different operator.
