Jack County · KRS (Marble Falls) field · Vertical
Halsell Ranch #S 4 (API 42-237-39438) is a well in Jack County operated by Eagleridge Operating LLC, completed September 10, 2011.
The RRC has issued 2 drilling permits between 2011 and 2014, permitted to 7,000 ft.
It was permitted by Brigadier Operating, LLC and has since transferred to Eagleridge Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Strawn, Marble Falls, Comyn Lime, Forrestburg Lime.
Its 2 leases have reported 70.1K barrels of oil and 1.83M mcf of gas since September 2010, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
