"The Cinnamon Geothermal prospect is located in the northeastern of
Mayonnaise Island, Indonesia. It is located in quaternary volcanic terrain
about 750 m asl. The various types of surface manifestations e.g. solfatara,
fumarole, steaming ground, mud pools and hotsprings are concentrated near
Cinnamon village. Few reconnaissance surveys had been conducted since
year 1977. To model the Geothermal Prospect of Cinnamon, one can use
Magnetotelluric and Gravity method.
Magnetotelluric method uses telluric current as natural source to
identify the resistivity properties of subsurface rocks. This resistivity section
can be used to identify the occurrence of clay cap. Gravity method can be
used to map the density response from the subsurface to detect a massive
density contrast that match the geological condition.
The integrated model of Cinnamon combining geophysical,
geochemical and geological data can be used to locate the reservoir, outflow,
and upflow for further drilling purpose and exploitation."
