Well EC-1 was drilled to a total depth of 4,829 feet (1,472 meters) and encountered a bottomhole temperature of 491°F (255°C), with the temperature gradient at the bottom of the hole rising at a rate of 7.1°F/100 Feet (129.1°C/km).

High temperatures in excess of 392°F (>200°C) were encountered in the well beginning at a depth of 2,625 feet (800 meters), which represents a potential high temperature reservoir interval in excess of 2,204 feet (672 meters).
Permeability was encountered and a slotted liner capable of supporting production was placed in the well. A preliminary cleanout flow from the well looked favorable and warrants formal testing. Flow test equipment is currently being fabricated for a planned test, which is expected to be performed within the next 4 to 6 weeks.
