“Volsung's integration of reservoir, wellbore, and surface network modelling has elevated our geothermal resource management. The speed and ease of wellbore modelling stood out, providing better predictions of reservoir and well performance.”Simon WebbisonVP, Exploration & Resource Management, Ormat Technologies Inc.
“"The remarkable speed of Volsung, along with its capability to run coupled reservoir-wellbore-surface network simulations, greatly improved our assessments of field performance. I can see that Volsung is truly an advancement for reservoir modelling in the geothermal industry."”Elisabeth EasleyGeothermal Resource Assessment Project Manager, PT Thermochem Indonesia
“Compared to TOUGH2, Volsung revolutionized our numerical modelling workflow by integrating everything in one software package. The drastic reduction in run times, from hours to minutes, paired with responsive technical support, has been commendable.”Fra-Olalem R. Cinco, Reservoir Engineering ManagerPhilippine Geothermal Production Company
Holistic simulation from subsurface reservoirs to surface systems
Volsung offers the integration of reservoir, wellbore, and surface network simulators with advanced features such as microgravity and subsidence forecasting, tracer modelling, Monte Carlo analysis, and cloud-based computing. Volsung helps you tell the story of your data with:
3D Reservoir Visualization and Control
Brynhild is a graphical interface used to develop and execute geothermal reservoir simulations and enhanced 3D visualizations to interpret model results.
Key features include clean visualizations that enable collaborative model development, simplified workflow from conceptual to numerical modelling, runtime control, grid-independent setup, TOUGH2 model import, and compatibility with Leapfrog Energy.
At Volsung’s core lies a highly efficient reservoir simulator that outperforms standard simulators in speed tests. Using heat and mass balance equations, Volsung replicates the flow of fluids through rock.
With its innovative use of GPU technology, it reduces model development time and offers faster simulations both locally and on cloud platforms.
Gudrun: Wellbore Modeling
Designed with visual features and built on sound physical principles, Gudrun provides detailed wellbore models in less time, enabling greater insight into well performance.
Automated Model Calibration Tools
These tools enable efficient automated calibration and uncertainty analysis. They effortlessly incorporate calibration field data and support autonomous modelling on cloud-based computing systems, simplifying the modelling process.
Built on foundational principles akin to the wellbore simulator, Volsung offers detailed modelling of pressure drop and heat loss in pipelines.
Numerical Pressure Transient Analysis
Volsung includes a numerical pressure transient analysis (PTA) tool based on the McLean (2020) framework. Using a radial model, it offers features such as standard pressure derivative plots, different boundary types, multi-rate tests, and more.
A compact yet powerful tool, the thermodynamic table assists users in querying thermo-physical properties of working fluids. Compatible with all steam tables implemented in Volsung, it aids in phase transition calculations and offers automation through Python modules.
We recommend you use Windows 10, with a reasonably fast processor, mid range graphics and 32GB of system memory.
