Integration and licensing
Licensing of VFP Designer.
Module is included in Geology Designer, Model Designer, and Network Designer. When starting the VFP Designer from these modules, a separate license is not required.
When starting the VFP Designer as a standalone program, it searches for available license in this order: Model Designer, Network Designer, Geology Designer

Assisted History Matching
AHM Module Overview
Main goals: Assisted History Matching, Uncertainty analysis, Production optimization
Variables setting Run typical scenarios from GUI or set keywords Match RFT\MDT\PLT measurement, do NPV optimization
Algorithms: Tornado, Latin hypercube, Grid search, Plackett-Burman Proxy models, Differential evolution, Simplex method, Particle swan optimization (PSO)
Integration: Integrated with Geology Designer, Model Designer, PVT Designer, VFP Designer simulation engine Variables in workflows, workflows are written automatically as python scripts
Visualize results: Graphs, tables, histograms, Tornado charts, Pearson correlation, multidimensional scaling (MDS), clusterization
New features in 17.3
The possibility to create user’s custom vectors (vector
calculator) is available.
The possibility to use the user’s vectors as objective function is
available (the graph must be named objf).
The possibility to create forecast variants with user’s
SCHEDULE section is available. Variables can be set in user
SCHEDULE.

Visualization at current time step
Transmissibility multipliers Transmissibility multipliers:
Grid Properties ->Initial -> Trans. Mult. along X (also Y, Z, X-, Y-, Z-). The
product of the transmissibility multiplier along X (MULTX), additional
transmissibility multiplier (HMMULTX, HMMLTXY) and fault transmissibility
multiplier (MULTFLT)
Grid Properties ->Calculated ->Trans. Mult. along X (also Y, Z, X, Y-, Z-). The
product of the transmissibility multiplier along X (MULTX) and fault
transmissibility multiplier (MULTFLT) from the start till the current time step
Load well data settings
Replace missing values with zero. If this option is used, the parameters for the well that
are missing in the file on the specific date will be replaced with zeros. In the example
above for the date 01.07.2014 water rate (column WWPRH) of the WELL15 is
considered as zero. If this option is not used then water rate at this date is equal to the
value from previous time step (01.06.2014).
Assign zero values to model dates missing in historical data. In the example above
there is no historical data for the date 01.08.2014. If this date exists in the model and this
option is used then oil, water rate and water injection rate will be equal to zero at this
date. If this option is not used then the rates at the date 01.08.2014 will be equal to their
values at the previous time step (01.07.2014).
