Geowatt: Engineering and simulations

Geowatt Engineering

Your partner for simulations of geothermal plants

The subsurface is an ideal heat source - and at the same time an ideal storage (geothermal storage) for heat and cold. For a geothermal project, simulations and measurement data on the subsurface are key tools for correct planning.

Complex simulations with the online platform GEOWATTCORE

For more complex plants, we can create adapted, project-specific simulation models.

Simulation models of standard plants can be created directly on the online platform GEOWATTCORE using a model wizard. In addition, GEOWATTCORE also offers the possibility to simulate arbitrarily complex plant concepts. Such complex simulation models are created by GEOWATT AG in cooperation with the customer. Optionally, the calculations can be carried out by GEOWATT AG or the special models can be delivered to the customer's account. The customer can then carry out the calculations independently. Support is ensured via the support chat.

Our expertise is the evaluation of measurement data

Evaluating and analysing measurement data requires experience and broad knowledge.

The local ground temperature and the thermal conductivity of the underground are the important variables for the correct dimensioning of a borehole heat exchanger system.

Borehole heat exchangers must be completely backfilled. The completeness, suspension density and quantity of the backfilling material introduced is best recorded and analysed continuously using fully automatic measuring equipment.

For quality assurance according to SIA 384/6, borehole heat exchangers must be flushed and tested for flow and tightness by the drilling company after backfilling. The flow and tightness test must be recorded electronically.

GEOWATTCORE enables efficient and precise design of simple to complex borehole heat exchanger and energy pile systems.

Special numerical software in the service of geothermal energy

Software with developer licences:
GEOWATT AG developes numerous special numerical software for many years.

HEX-B2	GUI software for borehole simulations, prognosis of the dynamic temperature and pressure in deep boreholes as a result from injection or production processes
HEX-S	Software for the simulation of dynamic fracture mechanic in a 3D-reservoir, dynamic hydraulic-mechanical coupling
FRACTure	3D-finite-element-solver, for dynamic hydraulic-thermal coupled calculations, can use mixed element types (hexahedrons, prisms, pyramids, tetrahedrons, quadrilaterals, triangle, lines)
ORION	3D-finite-element mesh-refiner, for the creation of highly efficient 3D-FE-meshs with strongly varying element sizes, uses mixed element types (hexahedrons, prisms, pyramids, tetrahedrons, quadrilaterals, tringles, lines)
GDT	Software package for the automatic evaluation of the risk of water bearing zones ahead during tunnelling, using measured temperature date from the tunnel as a selection criteria of probable scenarios by comparing the data with the results from a huge set of automatically generated numerical models of water bearing zones

Consultation and expertise

Geothermal systems are special structures with interfaces to energy planning, building services, civil engineering and the geology of the site.

The measurement of the ground parameters by our partners, the system simulations for the design by us or on GEOWATTCORE, the drilling of borehole heat exchangers and the construction of all connection lines and the distributors allow little qualitative leeway with regard to an overall plant that functions in the long term.
