Mittasch Carol L. et AL #4
Lee County · Serbin (Taylor Sand) field · Producing · Vertical
Mittasch Carol L. ET AL #4 (API 42-287-32046) is a well in Lee County operated by Trivista Operating LLC, completed July 1, 1988 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued September 14, 1987, permitted to 5,700 ft.
It was permitted by Coates Energy Trust and has since transferred to Trivista Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Taylor.
Its lease has reported 56.7K barrels of oil and 222K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
