Koehler Otillie #4 (API 42-029-35354) is a plugged well in Bexar County, plugged October 2, 2003, last operated by Aminex USA Inc..

The RRC has issued one drilling permit, issued April 26, 1984, permitted to 2,000 ft.

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

Completion filings report 2 formation tops, including Wilcox, Escondido.

Its lease has reported 151 barrels of oil and 14 mcf of gas since January 1993, last reporting in November 2003. The lease carries 3 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.
