Walker Unit 16-20 #1MS (API 42-317-43909) is a horizontal well in Martin County operated by High Noon Resources LLC, completed May 6, 2022 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued November 19, 2021, permitted to 9,200 ft.

It was permitted by Element Petroleum OP Iii, LLC and has since transferred to High Noon Resources LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Santa Rosa, Yates, Queen, Grayburg.

Its lease has reported 552K barrels of oil and 498K mcf of gas since September 2021, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
