Winsauer #1 (API 42-409-32402) is a plugged well in San Patricio County, plugged August 30, 2003, last operated by Dml Exploration Inc..
The RRC has issued 4 drilling permits (amended once) between 1992 and 1994, permitted to 4,212 ft.
It was permitted by Mortimer Exploration Company and has since transferred to Dml Exploration Inc. on the wellbore schedule.
Completion filings report one formation top, including Frio.
Its 4 leases have reported 383 barrels of oil and 270K mcf of gas since January 1993, last reporting in August 2003. The leases carry 4 wells, so these are lease totals, not this well alone.
