Ncoc Fee Unit #1 (API 42-505-34320) is a well in Zapata County operated by Merit Energy Company, completed December 10, 2001 and listed as swr-10-well on the RRC schedule, shut in July 1, 2007.
The RRC has issued 3 drilling permits between 1999 and 2001, permitted to 10,750 ft.
It was permitted by North Central Oil Corp. and has since transferred to Merit Energy Company on the wellbore schedule.
Completion filings report 2 formation tops, including Top Of Lobo 1, Top Of Lobo 6.
Its 2 leases have reported 337K mcf of gas since October 2001, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
