Andrews County · Parker (Wolfcamp Consolidated) field · Producing · Vertical
Parker Unit #18 (API 42-003-36219) is a well in Andrews County operated by Morningstar Operating LLC, completed June 7, 1991 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1988 and 1991, permitted to 9,840 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 7 formation tops, including Rustler, Yates, Wolfcamp, Pennsylvanian.
Its 4 leases have reported 5.48M barrels of oil and 8.96M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 210 wells, so these are lease totals, not this well alone.
