Simulation Model Building
To get the most out of your flow simulator, you need a high-quality
model as input. RMSSimgrid offers a user-friendly platform for
building, maintaining, and post-processing simulation models. This
includes robust grid generation for complex geometries, advanced
upscaling algorithms, and methods for defining well data for
simulations. The integrated environment promotes close
cooperation between geoscientists and engineers.
IN SUMMARY
• Build 3D simulation grids consistent with the structural
framework
• Handle simple and complex geometries equally easy
• Choose optimum gridding solution for fault representation
and zone handling
• Edit grid geometry in 3D
• Represent heterogeneities through industry-leading
upscaling techniques
• Create well data for flow simulation
• Quality control your simulation model through a rich suite
of tools
Local Grid Refinements
Local grid refinements may be required in well regions, for increased
accuracy. RMSSimgrid offers a large toolkit for generating local
grids, where local grids can be defined interactively or automatically
from well and parameter data.
Segmentation
Grid segments may be used to define regions in the 3D grid, for
instance as a fault block in the reservoir. Modeling and analysis of
individual regions can then be easily performed, where the amount
of data compared to the total model is reduced. Results for a
selected set of grid segments can be exported to the flow model,
making generation of sector models an easy task.
• Exchange data with external flow simulators in a
user-friendly way
Simulation Grid Design
3D grids can be constructed with any desired grid control and with
full user control over important parameters. Grid regularisation can
be used to achieve close to orthogonal cells, ideal for flow
simulations. Within each zone, advanced layering options are
available for accurate representation of reservoir features. Complex
geometries associated with normal and reverse faults are easily
handled, using pillar representation or staircase representation. Two
alternative fault representations are shown in the cross sections to
the right.
Control lines can be used to ensure that the grid reflects important
model features, such as reservoir boundaries, major faults, or well
geometries. Non-uniform grids with an optimum grid resolution are
also easily achieved through use of control lines.

Upscaling Grid Properties
Export to Flow Simulators
Upscaling algorithms in RMSsimgrid offers a rigorous approach to
handle the complex cell geometries associated with corner-point
grids. Direct sampling offers a fast and robust method for
identifying the cells in the geo grid contributing to each flow
simulation cell, minimizing an important general source of error in
upscaling. Tools describing the result of the sampling process are
available, allowing for detailed quality control.
Export of simulation models to leading flow simulators is easy and
user-friendly. Exported data can be renamed, to fit requirements in
the simulator of choice. Data for local grids can be exported
together with the global grid or separately.
RMSSimgrid offers a complete suite of upscaling techniques,
including static and flow-based methods. For flow-based methods,
alternative boundary conditions are offered, and a skin or buffer
region can be used to reduce artifacts of the selected boundary
conditions. Novel transmissibility upscaling methods can be used to
achieve a accurate representation of heterogeneities in the flow
model. A special method is available for upscaling permeability to be
used as input to well index calculations.
The reservoir modelling process is not complete until the
impact of heterogeneities on fluid dynamics is fully understood
and the predicted results match production history.
RMSSimgrid supports import of simulation results from
commercial simulators for further analysis and visualization
inside RMS. A rich toolkit for data analysis and for conversion
between data types makes RMS the ideal platform for
combined analysis of production data, geological data, and
seismic data.

Well Data for Flow Simulation
Based on well trajectories, data for perforation intervals, and the 3D
grid, RMSSimgrid can construct well data for flow simulations. Also
zone log data can be used as input, to secure that perforations will be
located in the correct zones in the 3D grid. The picture below shows
comparison between the perforated real trajectory and the grid
representation in a flow model.
