Swartz Ester #1
Liberty County · Cottonwood (Frio 2ND) field · Vertical
Swartz Ester #1 (API 42-291-05375) is a former disposal or injection well in Liberty County, last operated by Ashland Oil Inc.; its UIC permit is no longer active.
The RRC has issued one drilling permit, issued December 22, 2014, permitted to 8,114 ft.
It was permitted by Rim Operating, Inc. and has since transferred to Ashland Oil Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Miocene (undifferentiated), Het Lime, Frio.
Its 2 leases have reported 487K barrels of oil and 32.6K mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Rim Operating, Inc.; the EWA schedule now lists a different operator.
