Abstract
Process with 1D inverse modeling method was used to make resistivity
structure model for Jailolo geothermal field from magnetotelluric data which the
data (standard file *.EDI) consist of pseudo resistivity, phase and period. Data
converted by macroexcel software to use in 1D inverse modeling with IP2Win MT
software. Using data MT 5, the line cut Caldera Idamdehe as the expected center of
Jailolo Geothermal system and supported by manifestation at the peak and surround
Mount Jailolo.
As the subsurface imaging, this 1D resistivity structure model can identify the
lithology in geothermal system (caprock, reservoir and heatsource). The caprock in
Jailolo geothermal field has resistivity value < 10 Ωm, reservoir has range of
resistivity between 10 - 30 Ωm, and the heatsource has resistivity > 60 Ωm. From the
resitivity value identified the border between caprock and reservoir called BOC
(Base of Conductor) with the various depth and thickness for each measurement
points. The depth are interpolated to be the depth of BOC dispersion map and
isopach map then the updoming pattern that centered in the caldera Idamdehe can
be seen and then the upflow direction from the Jailolo geothermal field can be
interpreted. The updoming has shallow BOC depth caused by igneous rock intrusion
and the thin thickness is caused by boiling process.
