Key improvements in 18.2

Integration of modules Simulator, Network Designer, VFP Designer to build integrated models of reservoir-surface network.

Simulator: speed up in compositional model calculation by using vector instructions of CPU+GPU processors.

Simulator: different set of LGRs for restart models can now be added.

Geology Designer: an experiment for Geology Designer tables may be created without building a complete hydrodynamic model. This allows to perform a complete uncertainty analysis for geological parameters.

Geology Designer is now able to operate multiple grids for one project.

PVT Designer: gas hydrates curve is calculated and shown on Phase Envelope.

Model Designer: Cases Manager lets you to organize and manage model cases, assign them different options in RUNSPEC, GRID, PROPS, SOLUTION sections, add development strategies.

Module: Geology Designer Geology Designer

Multigrids

Several grids can be created in the same project

Module: Geology Designer

The created grids are available for hydrodynamic model creation

Fault lines

Correspond to the intersection between the faults and the objects used to build the grid (i.e. the horizons or the point sets)

Can only be calculated during the grid creation

Module: Geology Designer

Display of the top and bottom fault lines for

the top of the grid and the bottom

Fault lines Can be edited and then taken into account to rebuild the grid

Module: Geology Designer

Faults by polygons Module: Geology Designer

Faults can be created by polygons Create polygons in 2D and assign a depth

Create the fault: the polygons have to be ordered from the top to the base of the fault

Number of vertical sticks: number of polygons Number of horizontal sticks: points on the polygon

Import Raster Images (images without coordinates) Covering the whole data by default

Module: Geology Designer Raster Images

The well trajectories are imported first, then the raster image is loaded: the raster image covers the well data

Reference: infoterre.brgm.fr

Wells on the raster image: no coordinates are set

Point Set: coordinates of the wells

Can be edited: 3 vectors have to be set

Module: Geology Designer Raster Images

3 vectors are set

For this example, the objective is to superimpose the point set and the wells locations on the geological map
