State-Marshall #56 (API 42-047-32165) is a well in Brooks County operated by Hilcorp Energy Company, completed October 28, 2011 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits between 2004 and 2006, permitted to 7,700 ft.

It was permitted by Exxon Mobil Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 2 formation tops, including Frio, Vicksburg.

Its 4 leases have reported 226K barrels of oil and 2.28M mcf of gas since July 2002, last reporting in July 2026. The leases carry 17 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.
