12:00		 Side Event Thermo-Hydro-Mechanical Modeling (THM) and Ground Truth I (in English)
Virtueller Veranstaltungsort: Raum 1.1

Modeling geothermal reservoirs needs a lot of experience and a lot of parameters to give reliable results. It is often seen by reality, that the models are not describing exactly the behavior of the reservoir. What are the reasons for these discrepancies between simulation and real operation?

Of utmost importance for a reliable THM modelling are parameters from borehole and surface measurements, such as:

‐          Geometrical input

‐          Geological input

‐          Initial temperatures

‐          Petrophysical parameters

‐          Fluids, dissolved solids, not condensable gases

‐          Fault estimates, size, parameters, orientation

‐          Initial stress field, stress field development

‐          Pore pressure

‐          Temperature development

‐          Borehole fault intersection

‐          Internal (reservoir) erosion

Further issue are:

‐          Machine learning

‐          Extraction and injection

‐          Modelling, Software,

‐          Mathematical issues, codes, commercial software, computer capacity/ time

‐          Reservoir scales

‐          Parameters, rock, fluids

‐          Validation by logging

‐          Validation by pumping tests

‐          History matching, case histories, lessons learned

‐          Induced seismicity, seismic catalogue, max. magnitudes

‐          Thermal breakthrough

‐          Reservoir sustainability (50y)

The workshop will be a cross-over event between the O&G and the geothermal community.
