Structure Geology is a crucial parameter in constructing productive permeability in a geothermal system. Surface and subsurface structure correlation must be studied in greater comprehensive detail using robust data and analysis. PTS well data will give additional information about the permeability appearances in the well. Integrated structure and PTS trend analysis data are critical for defining potential permeability zones and being used as a baseline for next well targeting. The intricate structure of the Dieng field, particularly the Sileri area, makes it challenging to learn about because of differences in surface and subsurface orientation, as well as deviations in in situ stress from borehole image data. The classification and characterization of structural elements, including fractures and faults, from surface mapping and borehole image data versus pressure-temperature spinner trend will be the primary objective of this paper. As a result of the correlation of structure characteristics and PTS trend, we will eventually be able to identify productive fracture zones that can produce optimal feed zones.
