Ward County · Phantom (Wolfcamp) field · Horizontal
UL Sugarloaf 20-48 #5202H (API 42-475-37355) is a horizontal well in Ward County operated by Apache Corporation, completed May 2, 2018.
The RRC has issued one drilling permit (amended once), issued October 26, 2017, permitted to 12,500 ft.
It was permitted by Oasis Petroleum Permian LLC and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 14 formation tops, including Rustler, Salado, Castile, Lamar.
Its 2 leases have reported 697K barrels of oil and 860K mcf of gas since October 2017, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
