Geothermal Energy

In a society with increasing energy consumption, geothermal energy plays a fundamental role among renewable alternatives, harnessing the Earth’s internal heat to generate continuous electrical energy. Geophysical methodologies are one of the best tools for identifying and assessing the availability of these geothermal resources in great detail.

At GGI, we develop and apply unique methodologies that transform your MT, TEM, SEVS, magnetic, gravity and seismic data into high-resolution three- and two-dimensional models to provide greater certainty in identifying geothermally relevant features of the geological environment, including:

Three-dimensional delimitation of geothermal basins and reservoirs.

Geophysical characterization of the reservoir and host rocks.

Location of areas with geothermal potential.

Identification of structural lineaments.

Discrimination of different reservoirs and geological units.

All of this provides comprehensive support for establishing both conceptual geothermal models in the exploratory stages and reservoir models in operating geothermal fields.

Solutions

3D inversion of AMT/MT data

  • Three-dimensional inversion of MT data (apparent resistivity, phase and tipper) based on the finite element method.
  • Interpretation of 3D models for the identification of structural lineaments as well as shallow and deep reservoirs.

Two-dimensional cross-gradient joint inversion in geothermal applications

  • Two-dimensional cross-gradient joint inversion of MT, DC, gravity, magnetic, seismic and well log data.
  • Identification of geological units and their associated characteristics, both in the mineral and fluid phases, using images of multiple physical properties (geospectral images).
