Provide an integration of methods from visualization, computational

steering and reservoir simulation

Establish an integrated, modular decision-support system that allows the

user to steer and learn from simulations in an intuitive way

Design structures to create uniform interface layer between data set

structures used in reservoir simulation and the interactive visualization

program

Implement appropriate steering techniques specific to reservoir

simulation domain

Development of an interactive software environment that supports a

generic framework for visual steering

Integration with existing workflows and commercial and in-house reservoir

simulators for black oil, compositional, thermal, streamline simulation, and

also geoengineering workflows

Intuitive user interface that encourages natural collaboration of

interdisciplinary teams of geologists, engineers, and geophysicists

Handle multiple simulation models from at least one base case

Efficient exchange of control parameters and access to results as the

simulation progresses, without degrading the overall performance of the

simulator

Lack of options in available commercial packages to explore specific

simulation parameters on the fly, interrupt, etc.

Multiple run monitoring and the simulation results analysis and post

processing are all done through a single UI

Start, pause, restart simulation runs and configure multiple forecast

models are possible with very little effort

Static and dynamic reservoir properties in the model are easily viewed as2D/3D maps, graphs, histograms, scatterplots, etc.

Finding satisfactory solutions with few flow simulations

Refinements can be included to improve the results according to the

objectives of the study

Possibilities to treat parameters, combine them gradually, join different

parameters as simulation progress in time and use representative models

to integrate the effects of different uncertainties considering a production

strategy

Written in C# using WPF

The main design pattern is MVVM (Model-View-ViewModel)

The graphing is done using Windows Forms Charts with a WPF

wrapper

Two main UI threads along with a few other threads that handle

operations like processing data in the background

Simulations are run in the background using CMG's simulators, andthe SR2 reader is used to parse property data for the graph

visualization

The proposed approach derives multiple simulation models from at least one base

case, providing control parameters that can be changed at any time during the

simulation process.

The steering framework permits the visualization of the ongoing simulation

allowing the user to visualize 2D/3D maps, cross-sections, 3D volumes and graphs

that can be built on the fly and are updated as the simulation job progresses.

At any time during the simulation process, and even after the simulation comes to

an end, the user may build and animate all possible graphic images, controlling

different playback modes and ranges, forward and backward speed, thus providing

a framework for integrating dedicated tools for exploratory visual analysis.

The user has the flexibility to compare different alternatives, to correct an

unacceptable reservoir dynamic behavior or to seek an improved developmentalternative.

New jobs can be restarted from any intermediate step along the processing time of

a base case thus creating corresponding derived cases. As multiple derived cases

become available, they may be analyzed by comparing or operating on imagesfrom different derived cases and their respective base cases.

A derived case can lead to further derived cases as part of a derivation tree.

At user discretion, any derived case may be transformed into a new base case

where the sequence of controls includes the controls pertaining to the base case

and all the control modifications applied as part of any subsequent derivations.
