Migri, developed by Migris AS in Trondheim, Norway, is a comprehensive software solution for simulating, animating, and visualizing the complex processes involved in the generation and migration of hydrocarbons within interactive 3D models. The tool combines probabilistic Monte Carlo techniques with innovative migration modelling process description to reduce geological uncertainties and assess the petroleum systems and charge risks in exploration.
The core simulation techniques within Migri originate from concepts developed during and after the PhD of Øyvind Sylta in 2004. For further details on this, you can refer to the associated publications available on the Migris website (www.migris.no/technology/publications). Some of the key features that set Migri apart include:
Flexible Meshes: Migri allows the use of non-regular meshes, which are vital for accurately modelling faulted flows.
Sub-Layer Elements: Each layer can be subdivided into numerous sub-layers, enhancing the modelling capabilities.
Dynamic Flow-Grid Elements: These elements automatically adjust themselves based on carrier dip changes during burial.
Variable Hydrocarbon Saturations: The software accommodates non-uniform hydrocarbon saturations within each modelled element, leading to more precise simulations.
Capillary Leakage Model: Migri incorporates dynamic capillary leakage with a model that considers cap-rock hysteresis effects.
Fault Migration: The software supports the migration into, along, and out of non-vertical fault surfaces.
Monte Carlo Integration: Integrated Monte Carlo simulation and analysis functionality is a significant aspect of Migri.
