2nd SEG Geophysics in Geothermal Workshop


1–2 November 2023
Jakarta, Indonesia

Workshop Overview

Following the well-attended, inaugural SEG Geophysics in Geothermal workshop in October 2021 (online), this event provides an in-person forum for experts to meet and discuss updates on the relevant geophysical aspects of low, medium, and high enthalpy geothermal resource exploration and development and production monitoring.

This workshop will cover multi-disciplinary methods (ground, airborne, and downhole surveys), data processing, modeling, and interpretation phases, including aspects such as integration and machine learning. We encourage informative and innovative submissions addressing the themes below, highlighting both where and why an application was successful, or not, and sharing the lessons learned.
