Rockfield have been provided with funding through the WEFO (Welsh European Funding Office) programme in order to enhance the level of capability held within the Elfen software framework to undertake Geothermal applications. A number of key developments are required for this capability and a feasibility study funded by WEFO has enabled Rockfield to fund this internal research activity.
A number of modelling features and enhancements are required to suitably represent a typical geothermal application.
Therefore, the major factors to consider in order to predict the fluid fluctuation of temperature through this geothermal system will be:
Furthermore, since convection is a key heat transfer mechanism, the following properties/parameters of the fluid flow are also important:
Based upon the above tasks required, Rockfield have completed a feasibility study to see what the effects of these developments will have on the existing framework contained within the Elfen software and also to check that all of these above recognised developments are actually critical in providing a fit-for-purpose solution.
Key project deliverables:
The key project deliverables from this feasibility study will be a report that encapsulates all of the required tasks that are needed to enable the Elfen software to simulate a typical geothermal application.
There is a need within the industry for companies to better understand the geothermal conditions in order to increase efficiently and economically produce clean energy. Due to the recent pressures on the Oil & Gas operators there is a more urgent need to reduce carbon and improve renewable operations.
Many of the software’s available on the market today do not provide enough physics in their models and rely on assumptions in a variety of different areas within the geothermal process. All of these assumptions provide uncertainty of the inter-dependant process in the subsurface region. There is a need for a full-physics approach to enable accurate assessments of the effects of continuous geothermal energy.
