Parker Unit #21 (API 42-003-33965) is a plugged well in Andrews County, plugged October 28, 2009, last operated by Chevron Midcontinent L.P..

The RRC has issued 2 drilling permits between 1984 and 1990, 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 4 formation tops, including San Andres, Wolfcamp, Pennsylvanian, Canyon.

Its 3 leases have reported 4.42M barrels of oil and 7.58M mcf of gas since January 1993, last reporting in February 2012. The leases carry 139 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.
