Permedia - Basin Tools

Petroleum Migration

The first commercial solver to use modified invasion percolation algorithms to simulate migration and reservoir filling, Permedia's high-resolution petroleum migration simulator rapidly simulates multi-phase flow behavior in porous, faulted and fractured media to predict petroleum migration trajectories and highly detailed petroleum emplacement patterns.

Features

• Speed
  Permedia Migration runs in a fraction of the time of other simulators and works in both 2D and 3D. Simulations of the most complex models run in just minutes to a few hours.
• Native mesh support
  Run simulations on native PetroMod, Temis, Gocad and other meshes, without any conversion. Adding support for additional mesh types is straightforward.
• Multi-component
  Permedia Migration's transport algorithms are designed from the ground up to handle multi-components using a flexible reactants and reactions scheme.
• Tracers
  Permedia Migration's sophisticated tracer scheme allows you to track component origins based on facies, layer, category maps, or any property. With genetic tracers, visualize the 3D fetch for any accumulation in a system with point-and-click ease in 3D Viewer. Maturity tracers are also provided.
• Biodegradation
  Model the risk and effects of biodegradation. Added in collaboration with the Bacchus 2 Consortium at the University of Calgary, Permedia Migration incorporates the very latest technology and concepts for simulating the effects of biodegradation on petroleum properties.
• Petrofracturing
  Migration supports petrofracturing in the presence of large oil petroleum columns, where this failure criteria may be specified on a per-lithology basis.
• Quick-looks
  Data are not always available for ultra-high resolution hydrocarbon migration studies. Permedia provides a number of tools with which migration and volumetric analyses can be rapidly performed using a minimal amount of data.
• Mesh overrides
  Use any basin mesh as a “base case” and create multiple source and seal scenarios as input to Migration, without re-running the original basin model.
• Any lengthscale
  Permedia does not require you to learn different workflows for different scales of investigation. Use the same tools for reservoir filling simulations as well as classical basin-scale migration.
• Extensible
  Permedia Migration includes an open, accessible application programming interface (API) for adding custom code so that you can model proprietary reaction schemes.
• Multi-threaded
  Permedia Migration is designed to take advantage of multi-core processors.

Select a movie clip below: Any lengthscale Core, reservoir and basin migration. Permedia does not require you to learn a different workflow for different scales of investigation. This example shows a core image that was used to build a model for a single phase migration simulation. The colors represent time of petroleum invasion. The same workflow can be used to build basin-scale models. Conditioning fabrics Downscale coarse basin models. Use basin-scale hydrocarbon generation, expulsion and migration model results to "initialize" reservoir-scale assessments. In this example a time-varying petroleum charge was introduced into the margin of a high resolution reservoir model. Within the reservoir three separate gas-dominated accumulations ultimately form. Top seal leakage is occurring from the shallowest accumulation. Red is gas, green is oil. Regional scale Interactive fill-spill studies using any map. The accurate prediction of hydrocarbon migration trajectories requires that potential flow conduits, baffles and seals be described at as high a resolution as possible. With Permedia, coarse low resolution basin models can be downscaled using conditioning fabrics. This example shows a simple 2D basin model to which a conditioning fabric has been added from seismic data. The colors represent petroleum phase.
