Cobra #1 #3 (API 42-401-33627) is a well in Rusk County operated by Sabine Oil & Gas Corporation, completed November 30, 2012.
The RRC has issued 2 drilling permits between 2005 and 2012, permitted to 10,950 ft.
It was permitted by Nfr Energy, LLC and has since transferred to Sabine Oil & Gas Corporation on the wellbore schedule.
Completion filings report 11 formation tops, including Nacatoch, Woodbine, Paluxy, Tma.
Its 2 leases have reported 12.6K barrels of oil and 887K mcf of gas since September 2005, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
