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).
