SIM Reservoir
SIM Reservoir helps reservoir engineers make better decisions.
SIM Reservoir provides you with the tools to define optimal well trajectories. Through very fast comparison of simulation runs, history matching and clever cell filtering mechanisms you can identify the optimal target cells for new wells faster and with more confidence than before. Identify water cut distribution in seconds. With the 3D trajectory editor you can then create new well trajectories directly in the same 3D environment and export them.
SIM Reservoir enables you to interactively visualize, combine and manipulate multiple sources of data to help better understand reservoir behavior. SIM Reservoir is a high performance visualization tool that is designed from the ground up to be fully interactive and responsive at all times, regardless of how much data you load and combine into a single 3D view.
Understand the behavior of fluid flow through streamlines, vector fields and time animation. Work efficiently and focused through the extended use of intuitive interaction in the 3D workspace. Through intelligent color mapping of your properties hidden features in your simulation are revealed, enabling an improved understanding of pressure waves and fluid front movement.

Making a comparison analysis in 3D between two simulation runs is made very simple in SIM Reservoir. Open the simulation run and select the comparison run. The analysis is done in a second and all properties are available and displayed in easy to understand red-white-blue colorgradient. The first figure shows a 3D comparison analysis between two runs (A and B) with the pressure differences appearing as blue when positive and red when negative. The second figure illustrates how multiple properties can be shown in views with 3-Phase (Oil-gas-water) cross sections on model A and B and well production pie charts in the difference analysis. |

SIM Reservoir allows you to import and visualize RFT data into the simulation. The RFT cells with associated observed and simulated values are displayed in a clever difference colormap allowing you to quickly identify areas where there is a good match (white), overestimated simulation values (blue) or underestimated simulation values (red). This way of displaying differences between observed (measured) and simulated values of pressure and saturations may reveal geometric problems within the model not necessarily identifiable through standard 2D graph plotting. If for instance an area of the reservoir (upper left corner) or a particular layer is constantly overestimated, it is immediately identified in the 3D view. Import and visualization of any logs (LAS format) can give similar visual information. Figure Y illustrates 3 wells with associated RFT analysis cells and 2 wells with las logs along the trajectory. Clicking on either objects will give the user information on the observed and simulated values, the log value at the clicked depth etc. |

Through simple filtering mechanisms SIM Reservoir enables the user to interactively and quickly identify targets. Filtering cells based on multiple grid properties as well as geometric properties like “do not show cells that are completed” and “do not show cells that are being intersected by existing well trajectories” allows the engineer to quickly identify the best spot for a new well. The user can then select to export the particular cells by picking them interactively in the 3D work space, or create a proposed well trajectory simply by clicking on the cells and building a trajectory on-the-fly. The trajectory can later be exported in ASCII format to be used as input for any well planner tool. The figure illustrates how a well trajectory can be created through “hot spot” cells based on multiple selection criteria (high porosity, oil saturation, permeability and non completed cells). The remaining “pockets” of cells are colored by pressure with a red-white scale (high-low). |

Increasing the model size of your simulation will increase the accuracy of the simulation but also increase the time spent to run and analyze the simulation. In the past, two main obstacles were present; increased simulation run-time and inadequate solutions to properly and interactively visualize and post-process these large simulation runs. SIM Reservoir solves the second obstacle, through the use of level of detail algorithms and optimized caching, ensuring you that working on large datasets does not decrease the performance. Since analyzing and post-processing large datasets is no longer an issue, it may be worthwhile to increase the size of the model and get a more accurate picture of your reservoirs physics and dynamics. Once a simulation has been performed intelligent color mapping will help you identify areas with large activity and good candidates for local grid refinement (LGR). Filtering out homogenous areas will enable you to upscale the simulation grid based on reservoir characteristics instead of arbitrary field-wide geometric upscaling. Once the LGRs and nested LGRs have been defined, subsequent simulations will run faster and provide more accurate results. |

SIM Reservoir allows you to visualize multiple aspects of your reservoir in one view. You can add as many ISO-surfaces as you like, include vector fields and streamlines, add and interactively drag cross sections across your model to identify fluid behavior. The figure shows how a single view can include multiple sources of information. Pressure fronts arising from the two production wells are shown as ISO surfaces surrounding the wells. Vector field visualization of the permeability eigenvectors will emphasize the principal direction and magnitude of flow. Production pies show how gas is produced in high quantities in the closest well. A clipping plane which is showing the 3-Phase property, Oil, Water and Gas (green, blue and red) highlights a water breakthrough taking place in the top right corner. The cross field layer is showing the pore volume and is slightly transparent to allow the user to clearly see the pressure fronts. If streamline simulations were performed, these too could have been added to the scene allowing the user to see connectivity of the cells and the simulated reach of the producing wells. |

SIM Reservoir allows you to fully interact with your data in the 3D workspace. Most applications will only allow you to maneuver and navigate in the 3D workspace making it a static “view only” environment. SIM Reservoir allows you to interact with the various objects in the 3D space keeping you focused on the actual data. One example of this is shown in the figure to the right. It illustrates how a J-Cross section with 3-phase data (Gas, Oil and Water) can be dragged across the model using the mouse pointer in the 3D view instead of forcing the user to modify draggers or clicking on buttons in dialogs or interface items that are completely detached from the visualization. Cross sections, layers, free sections, vector fields and clippers are examples of objects that can be manipulated in the 3D workspace. Creation of 2D views and changing parameters to the various objects can also be done within the 3D environment. The figure also illustrates how completion cells can be visualized with 3-phase property showing you which completions have water and/or gas breakthrough. |

Load all your data, interact with it and compare simulation runs without delay. Through optimized data formats, SIM Reservoir efficiently handles large datasets, multiple datasets and multiple sources of information while keeping the application interactive and without any loss in performance. Even large models with hundreds of millions of cells are loaded into the application in a matter of seconds. If you are in the business of comparing multiple simulation runs you know the process can be tedious. With SIM Reservoir you can save a lot of time and effort by performing a visual comparison that quickly shows you the differences between two simulation runs in full 3D. Loading a second model is just as quick as loading the first one. The comparison case, which is a complete 3D model where each cell contains the difference between the two cases, is computed and visualized in seconds and can be interactively examined with all the same tools as any other model. Work fully interactively with all three models visible and examine the details in multiple windows or on multiple screens. Thee optimized data formats in SIM Reservoir are created with an import engine that is either accessed through the SIM Reservoir graphical interface or run in standalone mode using command lines. Simulation output files from Eclipse or CMG simulators can be imported in addition to associated trajectory files or streamline simulation output from Frontsim. Since the engine is standalone and can be run through a command line interface, it can easily be scripted and appended to the simulation processing step on the server so that it is invisible in your normal workflow. The import engine can be run in parallel which means that your most demanding simulation results will still be imported quickly and efficiently making SIM Reservoir the only scalable solution that will handle both your present and future requirements. |
