DYNAMIC UNSTRUCTURED MESH ADAPTIVITY FOR IMPROVED SIMULATION OF GEOTHERMALWATER EXTRACTION IN RESERVOIR-SCALE MODELS
要約
A novel method to simulate near-wellbore flow in geothermal reservoirs by using dynamic unstructured mesh
optimisation and the Double Control Volume Finite Element method (DCVFEM) is presented. The mesh
resolution is dynamically adapted to a field of interest, allowing to focus the mesh resolution only when and
where it is required. Geology is represented by bounded surfaces whose petrophysical properties are constant
within each of this surfaces. We demonstrate that the method has wide application in reservoir-scale models
of geothermal fields, and regional models of groundwater resources.
