Koch T.K. #4
Jefferson County · Winnie S.E. (Hutcheson) field · Vertical
Koch T.K. #4 (API 42-245-31987) is a plugged well in Jefferson County, plugged June 15, 2000, last operated by Texcal Energy (GP) LLC.
The RRC has issued one drilling permit, issued December 5, 1989, permitted to 2,100 ft.
It was permitted by Solatex Resources, Ltd and has since transferred to Texcal Energy (GP) LLC on the wellbore schedule.
Completion filings report one formation top, including Miocene (undifferentiated).
Its lease has reported 407K barrels of oil and 328K 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.
