Project Title Imaging, Characterizing, and Modeling of Fracture Networks and Fluid Flow in Enhanced Geothermal Systems (EGS) Reservoirs
Project Type / Topic 1 Laboratory Call for Submission of Applications for Research, Development and Analysis of Geothermal Technologies
Project Type / Topic 2 Fluid Imaging

Project Description Field tests (Fenton Hill, USA; Hijiori, Japan) strongly suggest that our ability to image fluid flow and temperature distribution in enhanced (engineered) geothermal reservoirs (EGS) needs to be dramatically improved for optimizing the operation of injection and production wells and the placement of new wells. The proposed high-resolution mapping will provide additional information about fracture network geometry and induced deformation. Combining this information with the active seismic images will enable a more complete conceptual model of the fracture networks and fluid flow/temperature distribution in the EGS, which is vitally needed for successful EGS operations.
State New Mexico
