| Summary: | Study use gravity method has been conducted in the \"WILL\" geothermal field
to model the subsurface conditions of the study area. The model then used to
determine the geothermal system in the area.
Result of preliminary processing of gravity data is Complete Bouguer
Anomaly data which then filltering by upward continuation to separate regional and
residual anomaly. Residual anomalies data are then processed with derivative
analysis such as First Horizontal Derivative (FHD) and Second Vertical Derivative
(SVD) to identify rock structure and other possibilities. Seven 2D model was made
from residual anomalies data and correlated with FHD, SVD, and geological data.
There is 4 rock formation identified from the models, each with unique density
value, which is Waringin Formation (2,55 gr/cm3) such as reservoir, Pangalengan
Formation (2,30 gr/cm3) such as cap rock, Malabar Formation (2,50 gr/cm3),
Wayang-Windhu Formation (2,50 gr/cm3), and Alluvium (1,80 gr/cm3). |
