Parker Unit #1 (API 42-003-34178) is a well in Andrews County operated by Chevron Midcontinent L.P., completed March 14, 1995.

The RRC has issued 2 drilling permits between 1984 and 1991, permitted to 9,950 ft.

It was permitted by Union Oil Company Of California and has since transferred to Chevron Midcontinent L.P. on the wellbore schedule.

Completion filings report 5 formation tops, including San Andres, Wolfcamp, Pennsylvanian, Canyon.

Its 4 leases have reported 5.53M barrels of oil and 9M mcf of gas since January 1993, last reporting in July 2026. The leases carry 230 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

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