Petrash-Harris A #1 (API 42-021-31101) is a well in Bastrop County operated by Texas Vanguard Oil Company, completed June 25, 1988.
The RRC has issued one drilling permit, issued September 29, 1987, permitted to 5,500 ft.
It was permitted by Maxwell Production CO., Inc. and has since transferred to Texas Vanguard Oil Company on the wellbore schedule.
Completion filings report one formation top, including Taylor.
Its 2 leases have reported 1.53K barrels of oil and 109K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
