Tycoon D #770H (API 42-389-37194) is a horizontal well in Reeves County operated by U.S. Energy Development Corp, completed December 22, 2018 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 25, 2018, permitted to 11,500 ft.
It was permitted by Cog Operating LLC and has since transferred to U.S. Energy Development Corp on the wellbore schedule.
Completion filings report 8 formation tops, including Delaware, Castile, Bell Canyon, Cherry Canyon.
Its lease has reported 3.79M barrels of oil and 11.9M mcf of gas since September 2014, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
