3D Geological and Isothermal Model of Geothermal Field Based on the Integration of Geoscience and Well Data

Abstract

The Conceptual Model in The Geothermal Field can illustrate subsurface conditions. A conceptual model is usually made in 2D however, the 2D model is generally limited to providing subsurface images, overcoming these limitations it is very important to use a 3D approach to improve understanding of subsurface conditions. 3D modeling needs to incorporate the integration of Geology, Geochemistry, Geophysics and Well Data studies. Visualization of the 3D model in this study was made using Leapfrog Geothermal software. The data used is data from the literature that has been previously published. The 3D model can provide a clearer picture of structural geometry and is effective in understanding geological features in Geothermal fields. 3D modeling can reduce uncertainty in drawing subsurface conditions, especially the geometry of Geothermal system components. The 3D model is also useful as a guide for determining make-up well in the future. More data is obtained, better models can be made. This model can be used as a guide in developing Geothermal fields in the future.
