THE THE CHARACTERISTICS OF BASE OF CONDUCTOR IN X GEOTHERMAL FIELD BASED ON THE MAGNETOTELLURIC AND WELL DATA

The X Geothermal Field in Flores, East Nusa Tenggara, has surface thermal manifestations such as hot springs, fumaroles, and alteration rocks, which indicate potential geothermal resources. This research aims to model characterize the base of conductor field a supporting data for exploration studies. modeling was performed using 3D magnetotelluric inversion analysis that correlated with well data, i.e, drill cuttings, methylene blue, Pressure Temperature Test. According results, subsurface condition study area consists an argillic zone around 400-300 masl, transition 300 0 propylitic below masl. At elevation marks boundary between reservoir clay cap. BOC distribution map reveals average is 550 meters above sea level. northern part prospect 3,4 km2 research.
