Callahan County · Quest (Ellenburger) field · Vertical
Windham Carol #1C (API 42-059-36030) is a well in Callahan County operated by Encon Services Inc., completed December 6, 1989.
The RRC has issued 2 drilling permits (amended once) between 1989 and 1990, permitted to 4,700 ft.
It was permitted by Heart Land Petroleum Corporation and has since transferred to Encon Services Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Gardener, Gardner, Gray, Gray Sand.
Its 3 leases have reported 137K barrels of oil and 278K mcf of gas since January 1993, last reporting in July 2026. The leases carry 16 wells, so these are lease totals, not this well alone.
Operator of record
