Marolyn #1A (API 42-105-35367) is a well in Crockett County operated by Stuart Operating LLC, completed July 2, 1987 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued May 21, 1987, permitted to 1,500 ft.
It was permitted by Wynco Energy, Inc. and has since transferred to Stuart Operating LLC on the wellbore schedule.
Completion filings report 2 formation tops, including San Andres, Grayburg.
Its lease has reported 108K barrels of oil and 72 mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
