Vychopen A #4 (API 42-051-30375) is a plugged well in Burleson County, plugged August 21, 2000, last operated by Mag Exploration LLC.
The RRC has issued one drilling permit (amended once), issued March 5, 1979, permitted to 8,932 ft.
It was permitted by Bridge Oil Company, L. P. and has since transferred to Mag Exploration LLC on the wellbore schedule.
Its 3 leases have reported 176K barrels of oil and 1.07M mcf of gas since January 1993, last reporting in July 2026. The leases carry 10 wells, so these are lease totals, not this well alone.
