A New Geothermal Flow Assurance Simulation Software - GEOPRO

Webinars 28 February 2023

Geothermal energy is the only renewable energy source that is available 24/7, all year around, and in principle anywhere on the planet. It is a baseload supply, it has lower life cycle CO2 emissions than biomass and even Solar PV, and geothermal power stations have small footprints. Despite all these advantages, geothermal has only 0.4% of the electric energy market. The main problem is high cost, which comes from high CAPEX, high drilling costs, and aggressive geothermal brine causing corrosion, erosion, and scaling.

To help reducing costs, a new geothermal flow assurance software that leverages results and innovations from several large EU-funded geothermal research projects is under development. It features dynamic two-phase multi-component flows in pipe networks, heat transfer, thermodynamics, novel geofluid models and reaction kinetics, non-Newtonian fluids, structural dynamics, fluid-structure interaction, 3D multi-physics (especially fluids, structures, heat transfer), 1D-3D coupling, and more.

The software includes key innovations and findings from these research projects, for example guidance on applying coatings to reduce erosion/corrosion/scaling (H2020 Geo-Coat), a scaling reduction system (H2020 GeoSmart), drilling operations and fluids (H2020 Geo-Drill), and extended modeling capability of geofluids (H2020 GeoPro). Significant cost reductions are possible through improved designs and operations based on flow assurance simulations and optimizations.

FlowPhys AS, Norway

Per Kjellgren is the founder of the company FlowPhys AS, Norway, and has 30 years of experience with developing algorithms and scientific software in many different areas (CFD, flow assurance/process simulation, thermodynamics, structural dynamics, heat transfer, thermo-mechanical stresses, computational welding mechanics, fluid-structure interaction, aeroelasticity, fluid-acoustic interaction, multi-phase flows, turbulence modelling, numerical shape optimisation, active flow control, high-performance computing) with applications to oil and gas, geothermal, maritime, aeronautics, automobile, electronics, nuclear power, and medical devices. Per has authored/co-authored 24 scientific journal and conference papers, as well as many technical reports for companies.

He has supervised one PhD student and three MSc students. Per won a scholarship to perform research at the University of Tokyo, Japan, 1991-1995, which is awarded to only one student/year at the Royal Institute of Technology (KTH), Sweden. He also set a record, being the fastest student ever to finish BSc and MSc at the Dept. of Aeronautics, KTH, Sweden. He received an MSc from KTH in 1991, and a Ph. Lic. (“Tekn. Lic.”) from KTH in 1998. He held academic research positions at the University of Tokyo, Japan (1991-1995), Royal Institute of Technology (KTH), Sweden (1996-1998), and the University of Arizona, USA (1998-2003). Per has three patents in the areas of medical inhalers, seismic exploration, and vehicle aerodynamics. Per is the project manager for Flowphys AS in European geothermal research projects, such as GeoCoat, GeoDrill, GeoSmart, GeoPro, and GeoHex.
