'Constrain the mechanics and permeability of the rocks at Krafla and seek ways to increase the permeability of the reservoir to enhance productivity of the exploited geothermic wells'
Institute of Risk and Uncertainty and Landsvirkjun Energy Research Fund
Supervisors: Yan Lavallée and Andreas Rietbrock
Description: The goal of my project is to constrain the mechanics of the reservoir rocks in the Krafla geothermal system. The experimental work will describe the response of the lithologies at Krafla to different conditions of stress and temperature, and will constrain the permeability of the reservoir rocks (intact & broken) at natural conditions. This constraint will seek to solve the knowledge gap on “hot rock permeability” for more efficient exploitation of the Krafla reservoir. The study further aims to describe how fluid flow efficiency of the reservoir rock increases with thermal stimulation by water injection as well as during tectonic rifting events. - Email Guðjón
