Jackson County · West Ranch (Greta) field · Observation · Vertical
West Ranch -A- #231 (API 42-239-02586) is a well in Jackson County operated by Hilcorp Energy Company, completed August 1, 2017 and listed as observation on the RRC schedule, shut in February 1, 2026.
The RRC has issued one drilling permit, issued January 30, 1979, permitted to 5,750 ft.
It was permitted by Mobil Oil Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Catahoula, Frio, Gretta.
Its lease has reported 6M barrels of oil and 5.64M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 287 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.
Wells nearby
Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
