Geothermal Development in Colombia, South America

Exploring resources and conducting feasibility studies to improve geothermal development.

RESPEC has completed resource-exploration and feasibility studies under the Dewhurst Group at the Nevado Del Ruíz geothermal development project in Colombia, South America. This project was completed for Empresas Públicas de Medellín E.S.P. (EPM). Phase 1 included evaluating the legacy data, performing magnetotelluric surveys, and conducting preliminary three-dimensional (3D) conceptual modeling. A cutting-edge physical model of the exploration area was generated by using 3D printing technology.

Phase 2, which was funded by the United States Trade and Development Association for Nereidas Valley, was completed in 2015 and included targeted magnetic and gravity surveys, structural geology mapping, infrastructure evaluation, and detailed 3D reservoir conceptual modeling for exploration well targeting. RESPEC performed 3D conceptual modeling, exploration well targeting, resource assessment, and data collection services. Additionally, RESPEC set up multiple meteorological stations and a stream gauge station to characterize site hydrology. RESPEC also conducted a fiber-optic, distributed temperature survey to characterize the interaction between surface water and groundwater across the exploration site. Analysis of the meteorological data, stream flow, and temperature showed a strong reservoir pressure response to precipitation.
