28 Well construction Casing, tubing, perforation, squeeze, packer Visualization of construction along well trajectory Manual drag-and-drop addition and editing of properties of well construction objects Creation and import of custom object catalogs Selection of parameters of well construction objects as variables for matching experimental data (pressure drop measurements)

29 Create VFP table Creation of VFP tables by correlations (BeggsBrill, HagedornBrown, Orkiszewwski, Gray, etc.) Different correlations for vertical, deviated and horizontal parts of the wellbore Friction multiplier and Hydrostatic component of the correlation Specification of points to calculate correlations in the table form Normalization of VFP tables

30 Experimental data Entering the experimental data (pressure drop measurements) Matching of tables by selected measured parameters and variables (construction elements settings, Friction and Hydrostatic components) Application of the construction elements settings found by matching

31 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 Geology Designer Model Designer Network Designer VFP Designer

32 Assisted History Matching

33 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

34 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.

35 Graphical User Interface (Simulator)

36 Rock compaction transmissibility multipliers Calculated. Rock compaction Trans. Mult. According to ROCKTAB keyword Visualization at current time step

37 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

38 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 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 ( ). Assign zero values to model dates missing in historical data. In the example above there is no historical data for the date 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 will be equal to their values at the previous time step ( ).
