Santorini Unit #1H (API 42-115-33810) is a horizontal well in Dawson County operated by Laguna Texas Resources LLC, completed May 20, 2020 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued February 27, 2020, permitted to 12,000 ft.

It was permitted by Cgs Operating, LLC and has since transferred to Laguna Texas Resources LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Yates, San Andres, Spraberry, Dean.

Its lease has reported 642K barrels of oil and 1.06M mcf of gas since May 2020, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
