Gregg County · Willow Springs (Rodessa) field · Vertical
Castleberry Gas Unit #4 (API 42-183-30724) is a plugged well in Gregg County, plugged March 25, 2016, last operated by Sabine Oil & Gas Corporation.
The RRC has issued 2 drilling permits between 1988 and 1998, permitted to 7,900 ft.
It was permitted by Mass Energy, Inc and has since transferred to Sabine Oil & Gas Corporation on the wellbore schedule.
Completion filings report 8 formation tops, including Woodbine, Massive Anhydrite (marker), Bass Mass. Anhydrite, Henderson.
Its 2 leases have reported 1.85K barrels of oil and 202K mcf of gas since January 1993, last reporting in April 2016. The leases carry 3 wells, so these are lease totals, not this well alone.
