Koehler #4 (API 42-029-33717) is a plugged well in Bexar County, plugged October 1, 2003, last operated by Virtex Petroleum Company.

The RRC has issued one drilling permit, issued August 10, 1983, permitted to 1,800 ft.

It was permitted by El Dorado Oil & Gas Inc. and has since transferred to Virtex Petroleum Company on the wellbore schedule.

Completion filings report 3 formation tops, including Wilcox, Lit, Olmos.

Its lease has reported 199 barrels of oil and 6 mcf of gas since January 1993, last reporting in November 2003. The lease carries 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
