Gutierrez Chevron R. #1 (API 42-505-33870) is a plugged well in Zapata County, plugged December 4, 2013, last operated by Unit Petroleum Company.

The RRC has issued 2 drilling permits (amended once) between 1998 and 1999, permitted to 11,200 ft.

It was permitted by Chevron U. S. A. Inc. and has since transferred to Unit Petroleum Company on the wellbore schedule.

Completion filings report 3 formation tops, including T/Queen City, B/Queen City, T/Wilcox.

Its 2 leases have reported 1.3K barrels of oil and 1.08M mcf of gas since February 1999, with no volume in the three years through April 2026. The leases carry 2 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.
