Kyselica F. #1 (API 42-255-31173) is a plugged well in Karnes County, plugged October 19, 2006, last operated by Ampak Oil Company.
The RRC has issued one drilling permit (amended once), issued April 30, 1987, permitted to 4,100 ft.
It was permitted by Sinclair Minerals, Inc. and has since transferred to Ampak Oil Company on the wellbore schedule.
Its lease has reported 17.2K barrels of oil and 47 mcf of gas since January 1993, last reporting in March 2008. The lease carries 2 wells, so these are lease totals, not this well alone.
