Abstract
Kadidia-Sigi, Central Sulawesi's geothermal potential area has impermeable hoods with a high level of clay minerals (illite) in alteration regions around geothermal manifestations. Breccia rock samples were taken from one of the wells that had been analyzed to see the effect of temperature on 3D rock structure changes. Rock samples were given heat induction treatment with varying temperatures ranging from 24°C (room temperature), 100°C, 150°C, 200°C, to 250°C. Samples at room temperature that have been given treatment are scanned with a Micro- Computed Tomography Scan (µ-CT Scan) instrument. 300 images of the µ-CT Scan results were reconstructed and characterized by 3D changes in the fractures using digital image processing. The results are obtained in the form of the main parameters, namely aperture {e (T)}, density {Φ (T)}, and intensity {I (T)} which tends to increase polynomially.
