West Ranch "A" #174 (API 42-239-02529) is a well in Jackson County operated by Mobil Oil Corporation, completed June 1, 1964.

The RRC has issued 5 drilling permits between 1979 and 1996, permitted to 6,176 ft.

It was permitted by Meridian Oil Inc. and has since transferred to Mobil Oil Corporation on the wellbore schedule.

Completion filings report 5 formation tops, including Catahoula, Frio, Greta, Gretta.

Its 6 leases have reported 8M barrels of oil and 8.35M mcf of gas since January 1993, last reporting in July 2026. The leases carry 357 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
