What is Permedia software?

Permedia software (formerly MPath) is a modeling framework for creating, risking, querying and visualizing high resolution datasets related to petroleum systems modeling.

Complete with advanced querying and visualization tools, Permedia software is valuable to both the traditional basin modeler and reservoir characterization teams.

Permedia software is available in several different packages, and includes a suite of simulators linking regional, basin and reservoir modeling.

Permedia software's migration fluid-flow solvers are applicable to capillary-dominated flow operating under drainage conditions. Migration predicts petroleum migration trajectories and highly detailed petroleum emplacement patterns by rapidly simulating multi-phase flow behavior in porous and fractured media. Using Migration, you can model 3D, multi-scale, multi-million gridcell petroleum transport in a matter of minutes. Migration provides very high resolution model realizations of petroleum emplacement, at multiple lengthscales, but it cannot model petroleum recovery. Migration can tell you where petroleum is and how it got there, but not how it will behave under water flood.

Permedia software also includes pressure, continuity, and mixing simulators, developed as part of the Fluid Mixing Research Program. Not only can Permedia software predict where the petroleum is located, it can also provide information on its production properties.

Why use Permedia software?

It's fast. Migration executes a 100 million gridcell model in minutes on a modest workstation. And it can be run on distributed computing grids for fast execution of multiple realizations.

It works at high resolutions. With Permedia software, data doesn't have to be upscaled, averaged or simplified to use.

It honors uncertainty in input data. Permedia software can be used for risking the impact of a given input or input scenario. In fact, it is probably the best petroleum systems risking tool available since it can quickly evaluate so many realizations and scenarios, all at non-degraded spatial resolutions.

It's flexible. Using Permedia software, you can simulate single and multi-phase migration, identify rock bodies (e.g., pay zones), risk multiple realizations, and visualize the results in 3D. And Permedia software supports a variety of formats from other modeling packages while using open and well-described file formats for its own data.

It's easy to use. Permedia software uses straightforward graphical user interfaces for building models, entering simulation data, risking, and querying and visualizing the results.

How high a resolution can Permedia software handle?

Models with hundreds of millions of gridcells are possible due to the efficient way in which Permedia software handles memory resources. Essentially, data does not have to be "upscaled" to be used by Permedia software. If you have a basin model at seismic resolution, you can use it.

What makes Permedia Migration so fast?

Basin modeling packages typically use the same set of flow equations and solvers that are used in reservoir simulators. However, the balance of forces operating at production timescales is entirely different to those operating at geological (migration) timescales. The migration simulators honor the physics controlling petroleum migration and recognize that these fluids are moving at extremely low flow rates and are almost exclusively controlled by simple driving forces (i.e., buoyancy and external water pressures) and simple resistive forces (capillary pressure). The assumption of capillary equilibrium operating under drainage conditions allows Permedia software to avoid most of the numerical complexities of traditional migration solvers.

Are there any competing products for Permedia Migration?

No other product can model migration and reservoir filling at anywhere near the resolutions and speeds of Permedia software's migration simulator. Developed for more than 15 years, Migration includes a host of supporting technologies to enhance petroleum system modeling. Others are starting to copy our work, but we see this as an endorsement of our technologies. If you want to honor all of your input data at the highest resolution possible, honor the controlling physics of petroleum migration and have simulation results fast, Permedia software stands alone.

Is Permedia just about Migration?

No. Permedia software effectively bridges the worlds of basin and reservoir modeling, providing a rich set of tools for simulating processes that occur at regional, basin and reservoir scales.

Permedia software can be used to identify rock bodies (e.g., pay zones) in high resolution models. This type of analysis can be combined with migration results to answer queries such as: "Find all pay zones in a high-resolution input volume, charge the model with petroleum and tell me how much of my pay sees the charge." Or "find all high vertical coherency objects in the model, assume they're faults or fracture zones, and model them as such for migration purposes".

Permedia Petroleum Systems software includes a basin simulator for forward modeling pressures and temperatures in an evolving mesh, along with basin model building tools that allow you to build sophisticated 2D and 3D models.

In addition to all the features of Permedia Petroleum Systems software, Permedia Suite software includes a high-resolution reservoir fluid pressure, continuity, and mixing solver, reservoir filling simulator, and a black oil simulator.

Permedia Pore Pressure software is a flexible set of tools for conducting pore pressure studies.

Use Permedia Petroleum Systems 1D software to model sediment maturities, heat flow, compaction, source rock potential and any number of derived properties based on your own workflows.

All Permedia packages include Permedia Viewers software, a lightweight yet powerful suite of tools for visualizing, querying and ranking results; mapping tools for terrain, closure and category analysis; and tools for extracting data from volumes and performing transform operations on volumes and maps. One user described Viewers as "Gocad-lite with added simulators."

Can Permedia software be used for reservoir modeling?

Yes. Permedia Suite software includes mixing simulators specifically targetted to understand compositional resevoir filling, a Black Oil production simulator, and a reservoir filling simulator to simulate the emplacement of petroleum into high-resolution (e.g., seismic resolution) reservoir models. This is a new application of basin modeling and starts with the question: "given this high resolution petrophysical description of my reservoir, and assuming migration has taken place, where would I expect to see the petroleum? How much and what kind?"

What platforms does Permedia software support?

Permedia software runs on Linux (RHEL 4 and 5), and Windows (XP, Vista, 7), in 32- and 64-bit.

What data formats does Permedia software support?

Permedia software can use a large variety of file formats, including SEGY files, Irap, Eclipse, PetroMod, TemisPack, Zmap, CPS3, Petrel, and Gocad formats, and more.

Permedia software supports OpenWorks® data stores. Seamlessly read in GDI wells with traces, markers and trajectory, horizons, and GDI grids. Sub-select the data in the data store by district, project, interpreter and well lists.

Permedia software also has seamless links with PetroMod and TemisPack applications, allowing you to run dynamic simulations on PetroMod and Temis models and then co-render the results in 3D Viewer and query the results using Permedia software's post-processing tools, which are optimized for high resolution datasets.

Permedia Viewers software, the visualization and querying environment, supports dozens of industry formats, allowing you to co-render large, complex datasets from a variety of sources.

How does Permedia software interact with other basin modeling tools?

Permedia software supports PetroMod, Temis and Gocad meshes natively; you can run migration simulations directly on your basin models, without any conversion.

Why use coarse dynamic grids created in basin simulators in Permedia software?

Using conditioning fabrics, you can infill coarse basin or reservoir models with fabric information derived from seismic, geostatistical models, or other data, at its original resolution. Conditioning fabrics allow detail to be added to models at a resolution that is independent of the main modeling grid. In effect, using conditioning fabrics lets you "downscale" coarse basin models. One consequence of this is that petroleum migration calculations can be done at a much finer (e.g., seismic) resolution than the main input grid.
