THE STUDY OF GAS MIGRATION IN CRYSTALLINE ROCK USING INJECTION TESTS
Journal Title: UNKNOWN - Year 2012, Vol 24, Issue 1
Abstract
The study of gas migration in crystalline rock using injection tests is being carried out in the frame of the FORGE (Fate of Repository Gases) project. The Czech Technical University in Prague (CTU), Centre of Experimental Geotechnics (CEG) is participating in WP4 which is focused on disturbed host rock formations with respect to radioactive waste deep repositories. A series of in-situ tests is being conducted at the Josef Underground Laboratory. The aim of the testing is to simulate and study phenomena that might lead to gas-driven radionuclide transport in fractured crystalline rock. The in-situ tests combine migration and large-scale gas injection measurements; gas injection tests are being employed for the study of gas transport. For the purposes of comparison of the behaviour of the rock mass with regard to air and water a series of water pressure tests are also being carried out. The quality of the rock mass is assessed using rock mass classification systems.
