Penn State Lab Testing Fluid-Rock Interaction in Geothermal Reservoirs

Description

This project focused on assessment and discovery of fluid-rock interaction in geothermal reservoirs. We accomplished work in four main areas: 1) fracture formation and the relationship between fluid flow and shear failure, 2) assessment of fracture geometry and fluid permeability using novel acoustic measurements, 3) an improved understanding of how drilling, injection and geothermal production influence local seismicity, and 4) development of process based models for using induced seismicity to assess the critical stress-state in Earth's crust. This submission contains relevant true triaxial granite and shale experiments and associated run sheets accompanied with links to final technical report and presentation project slides.
