Jackson County · West Ranch (Marginulina 5000) field · Not Eligible for Allowable · Vertical
West Ranch -A- #528 (API 42-239-32583) is a well in Jackson County operated by Hilcorp Energy Company, completed April 15, 1996 and listed as not eligible for allowable on the RRC schedule, shut in January 1, 1998.
The RRC has issued 2 drilling permits between 1991 and 1995, permitted to 5,290 ft.
It was permitted by Meridian Oil Production Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 6 formation tops, including Discorbis Sand, Marginulina A, Marginulina B, Marginulina C.
Its 2 leases have reported 6M barrels of oil and 5.64M mcf of gas since January 1993, last reporting in July 2026. The leases carry 288 wells, so these are lease totals, not this well alone.
