Parker Unit #4218E (API 42-003-37707) is a well in Andrews County operated by Morningstar Operating LLC, completed January 29, 1996 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 21, 1995, permitted to 9,877 ft.

It was permitted by Union Oil Company Of California and has since transferred to Morningstar Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Yates, Wolfcamp, Pennsylvanian, Atoka.

Its 2 leases have reported 5.45M barrels of oil and 8.93M mcf of gas since September 1994, last reporting volume in April 2026. The leases carry 204 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.
