Abstract
A shallow temperature measurement at steaming ground of Gedongsongo manifestation, Ungaran Geothermal Prospect, shows that high thermal gradient occurs at 5 – 30 cm. This shows that a conductive heat transfer zone and low thermal gradient occur deeper (30 – 80 m), which implies a convective heat transfer zone. Some physical rock parameters such us bulk (wet) density, porosity, and saturation of liquid were also measured. These parameters would be an input to a heat loss assessment of the field.
