UL 20-44 Catalina #321H (API 42-475-37944) is a horizontal well in Ward County operated by Apache Corporation, completed September 17, 2019.
The RRC has issued one drilling permit (amended once), issued June 27, 2019, permitted to 11,595 ft.
It was permitted by Titus Oil & Gas Production, LLC and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 10 formation tops, including Rustler, Delaware, Clear Fork, Glorieta.
Its 2 leases have reported 202K barrels of oil and 493K mcf of gas since September 2019, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
