An Integrated 3D Geological and Isothermal Modelling to Better Understand Geothermal Reservoir

Abstract

Conceptual models are usually made in 2D during the Exploration stage. 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. This study presents some techniques to construct an integrated 3D model of a geothermal field. The geological setting of the field is defined from surface geological data. Identification of the reservoir area using the first appearance of the epidote and integrated with the static temperature of the well. Visualization of the 3D model in this study was made using Leapfrog Geothermal software. This 3D model can be used to help better understand the evolution of geothermal system, support drilling strategies and management of the resource.
