Seismoelectric effects for geothermal resource assesment and monitoring

Geothermal systems involve the injection of large amounts of fluid into the subsurface. Identifying fracture networks will significantly help

  1. to assess geothermal resources by mapping pre-existing fracture networks,  
  2. to inform on stimulation successes and risk mitigation by mapping newly activated fracture networks. Traditional seismic imaging techniques fail to resolve fluid-phase properties, while purely electromagnetic (EM) approaches provide limited, low-resolution constraints on the rock structure. 
Seismoelectric effects (SEE) arise from the seismic-to-electromagnetic conversion is naturally charged porous media with a certain degree of fluid saturation. With SEE, we leverage seismic and EM technique sensitivities. In this project, we offer an integrated SEE assessment for geothermal systems relying on numerical modelling, laboratory experiments and field surveys.
