EarthModel FT
Build your geologic model in days...
And update it in hours!
EarthModel® FT is an innovative geologic modeling system built around the revolutionary UpdateAbility concept.
UpdateAbility
EarthModel FT automatically tracks everything you do in the course of building your 3D geologic model, and can rebuild the model in minutes when you change or add inputs, or change any parameter.
Underlying every geologic model is EarthModel FT’s software architecture based on the unique UpdateAbility concept. As the workflow is built, EarthModel FT automatically records and documents the steps so that a complete history of the workflow is available at every stage of the project. Every petrotechnical item in the project (e.g. surface, 3D mesh or porosity model) “knows” its place in the workflow. It knows what went into its creation and what other items later in the workflow depend on it.
With UpdateAbility, changes to parameters cause direct and indirect results to recalculate in response to the change. All descendants update when the parent item changes.
Need to add a new horizon to your model? Need to edit a fault and then reconstruct the entire model, re-sealing all faults and horizons? With EarthModel FT updating the entire geologic model is easier than ever.
As an example, let’s say you have built a geologic model encompassing eight wells as shown here.
Now you find you have access to data from three additional wells that are outside your original area of interest. For some modeling programs, this represents a substantial amount of work to update the model to include these new wells. But not for EarthModel FT! Simply define a new area of interest that includes the additional wells, as shown here.
And then use UpdateAbility to rebuild the model in one step. In this particular example, it took less than five minutes to define the new area of interest and rebuild the model.
UpdateAbility works like a spreadsheet. Once you have built the spreadsheet, any change to the value or formula in a cell instantly causes the entire worksheet to update and stay current. In EarthModel FT, the result is a dynamic, living workflow where anything, anywhere in the project may be revised at any time, causing the model to rebuild automatically.
TrackAbility
Since EarthModel FT records all the details of the model being built, it also has a history that is easy to view and understand. This history is called TrackAbility, and allows you to go back to a model that was constructed months or years ago and quickly see how it was built. This also makes is much easier to pass an existing model to a different person to take over its maintenance and updating.
Assistants
Assistants in EarthModel FT step you through the model building process, link commonly used functionality, bring together viewers and parameters, and facilitate rapid movement between different items in the workflow. They automatically create groups and folders to store your data for a more organized project.
Speed
The ability to quickly update a model with UpdateAbility certainly makes it faster to maintain a geologic model than has been possible previously, but how about the speed in making the initial model itself? EarthModel FT also helps you build the initial geomodel more quickly, with a more streamlined workflow and faster geostatistical algorithms for populating your model. Clients have reported that using EarthModel FT enables them to build their initial model five to ten times faster than with other programs. Automating the model building process via Assistants also helps you get to results in less time.
Low Frequency Modeling
EarthModel FT can also be used to build complex structural models for propagating well information using distance-based interpolation. These models can be transferred to a seismic grid and used as the low frequency stabilization for pre- and post stack deterministic inversion or geostatistical inversion projects.
Structural Modeling
EarthModel FT handles complex models with large numbers of faults. The Assistants make it easy to deal with many faults and horizons, while still retaining all the advantages of UpdateAbility.
EarthModel FT allows you to repair faults and automatically truncate against surfaces. In the example below, this fault was interpreted in another package and imported to EarthModel FT. Truncation against other surfaces was a problem. But UpdateAbility makes it possible and easy to fix—just adjust the fault nodes and the whole structural model updates as required.
Indicator and Reservoir Property Modeling
The reservoir properties, such as lithofacies, porosity and permeability, can be determined either using the geostatistical techniques within EarthModel FT, or in combination with Jason’s seismic-driven reservoir characterization methods. In combination with the RockScale module of EarthModel FT, 3D lithology and property models derived from seismic data can be properly imported and used as 3D trends to guide the geostatistical simulations. This method produces far superior models compared to importing 2D attribute maps to guide the simulation.
3D Seismic to Simulator
Jason is the only company to offer end-to-end capabilities to start with well logs, geology, and seismic and deliver static models to the simulator that history match with little or no intervention. Building models that can be defined in both geophysical and geological terms is a key element in this process.
EarthModel FT meets these requirements, building the complex model to support the advanced seismic reservoir characterization processes that deliver accurate rock property volumes from the seismic data. These model realizations are constrained to honor all the information known about the reservoir, and so have a very small standard deviation. These models are easily upscaled, ranked, and transferred to your reservoir simulation software for dynamic simulation.
See the An Integrated Case Study from Seismic to Simulation through Geostatistical Inversion paper for a case example of this workflow.
