Noelke 20 #1 (API 42-105-37685) is a well in Crockett County operated by Aspen Operating Company L.L.C., completed July 14, 1997 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued April 29, 1997, permitted to 2,800 ft.

It was permitted by Marathon Oil Company and has since transferred to Aspen Operating Company L.L.C. on the wellbore schedule.

Completion filings report 4 formation tops, including Yates, Seven Rivers, Queen, San Andres.

Its lease has reported 506K barrels of oil and 1.1K mcf of gas since July 1997, last reporting in July 2026. The lease carries 5 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.
