Abstract: | Laboratory based experimentation is a cost effect method for exploring and testing developments in enhanced geothermal systems. Flow-through experiments are a powerful tool in such investigations. A wide range of concepts are presently being investigated using flow-through systems. These vary from the testing of new flow fluids, water-rock interactions at critical and super-critical temperature of water, and the development of new de-scaling methods. At the University of Adelaide and the division of mineralogy of the South Australian Museum, a wide range of water rock interactions are under study. Fundamental studies include coupled dissolution-re-precipitation and mineral replacement, with a focus on changes in porosity. Important applied studies are in progress on materials from exploratory wells at potential EGS sites. A flow-through system is used to investigate water-rock interactions at temperatures and pressures found at the site being explored. |
