GREAT Cell Laboratory
GREAT: Geo Reservoir Experimental Analogue Technology. True triaxial experimental investigation of coupled thermo-hydro-mechanical-chemical processes in subsurface applications.
To investigate the coupled thermo-hydro-mechanical-chemical processes and their interactions relevant to industrial applications and geoenergy technologies, the GREAT Cell (Geo Reservoir Experimental Analogue Technology) has been designed and built in collaborations with Heriot-Watt and Gottingen Universities.
The GREAT cell (Geo-Reservoir Experimental Analogue Technology) is designed to recreate subsurface conditions in the laboratory to a depth of 3.5 km on 200 mm diameter rock samples containing fracture networks.
Secure and sustainable utilisation of the subsurface for low carbon energy applications such as CO2 storage, geothermal energy and energy storage requires the ability to understand, predict and monitor the physical response of the geo-reservoirs and the surrounding rock mass to changes in fluid pressure, stress, temperature, fluid composition and biological activity.
These physical responses are often described as combinations of thermal (T), mechanical (M), hydraulic (H), chemical (C), and micro-biological processes (B). All of these processes are interdependent to some degree, with feedbacks and degrees of coupling among themselves that depend on the particular situation and technology under consideration.
The GREAT cell (Geo-Reservoir Experimental Analogue Technology) represents an important new development in experimental technology, uniquely creating a truly polyaxial rotatable stress field, facilitating fluid flow through samples, and employing state of the art fibre optic strain sensing, capable of thousands of detailed measurements per hour.
Within the GREAT Cell laboratory the following facilities are available:
