3 Versions March: tnavigator 17.1 June: tnavigator 17.2 September: tnavigator 17.3 December: tnavigator 17.4

4 Key modifications of 17.2 New module - Network Designer 3D Seismic (Geology Designer) Seismic interpretation: manual, guided autotracking, seeded 2D autotracking, seeded 3D autotracking, time to depth conversion AHM integration with Geology and Model Designer Variables can be added to the workflow Geosteering (Geology Designer) Horizontal display of logs for planned and drilled well, 2D view and calculation of synthetic log using reference well

5 Geology Designer

6 Floating tabs Place tabs in separate windows or next to each other via splitters Create multiple tabs with different settings in View. Windows

7 Workflows Record actions to user workflow Uncheck temporary selected actions in the workflow Test workflow before running Add variables to workflow to run AHM (variables can be added to Horizon Calculator, Property Calculator, Adjust Variogram parameters, Property Interpolation, Create RP Tables, Create Equil tables.)

8 Work with Seismic data Manual interpretation, Guided Autotracking, Seeded 2D autotracking, Seeded 3D autotracking 3D Correlation to create seismic 3D horizon according to picking Load time-depth law as a Log for wells Create horizon via seismic horizon and time-depth law

9 Well correlation Show distance between wells Load, visualize and edit Comment Log Set scale for each well and each log independently Hot keys for frequently used buttons on Well Section Possibility to edit discrete log

10 Geosteering Configure geosteering: reference well, planned well, drilled well Create synthetic log using reference well Simultaneous display of two correlation profiles (planned well and drilled well) and 2D view

11 Additional possibilities Visualize properties according to zones is available (Zones Filter) Load horizons from RESCUE files Object Settings (right mouse click on the object and choose Object Settings): Change object settings (property, horizon, log and other): name, color, template that specifies object s units and palette Use standard templates or set user s template is available Discrete palette can be set for object templates. For templates one can set for each value it s name and color

12 Model Designer

13 Common features available in Model Designer and Geology Designer Floating tabs & Multiple tabs Workflows Object settings Zones filter

14 Create model with Hysteresis Check Hysteresis in Definitions Add IMBNUM regions Add RP tables

15 IMEX, STARS, GEM format Add and Edit keywords in formats STARS, GEM, IMEX Export keywords in formats STARS, GEM, IMEX So model in STARS, GEM, IMEX can be loaded to Model Designer, edited and exported in its initial format

16 Wells Rules Set additional options in the rule Well Specification Parameters: reference depth, drainage radius, crossflow flag and other Load time in formats HH:MM:SS, HH,MM,SS, HH.MM.SS in event and history loading dialogues. Dates with hours can be created in Schedule section For thermal models historical data for steam injection can be loaded and used in WINJTEMP creation

17 PVT Designer

18 Phase envelope Optimization of graphical interface Vapour fraction is visualized via color and (or) contour lines and filling

19 Black Oil Variants Load from file (standard E100 format) or create from compositional variant Visualize and Edit PVT tables Analyze phase compressibility to check consistency of PVT tables

20 Network Designer

21 Development plan tnavigator Modeling of surface network of well production gathering. Integration with PVT Designer for setting fluid composition tnavigator VFP Designer Module. Integration of Network Designer with VFP Designer tnavigator Export of well regimes (BHP, WHP controls) from hydrodynamic to Network Designer tnavigator Integrated models: subsurface and surface parts See the detailed presentation Network Designer about this module

22 Assisted History Matching

23 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, Module Designer, PVT Designer, simulation engine Variables in workflows Visualize results: Graphs, tables, histograms, Tornado charts, Pearson correlation, multidimensional scaling (MDS), clusterization

24 R2 table to check HM quality For selected object and parameter a set of (P k (H); P k (C)), k = 1, N are distributed on the plane, where P k (H) - historical value of this parameter and P k (C) calculated value at k-th time step. Trend T k is calculated using the least square method. R2 are calculated as following:

25 Mismatches settings Define acceptable mismatches for each point independently

26 Graphical User Interface

27 Create a screenshot option Available in Simulation GUI and in all Designers Save screenshot to vector or raster format, copy to clipboard or print

28 tnavigator kernel

29 CPU+GPU Calculation of compositional models via CPU+GPU is available. (The only GPUs starting Pascal architecture are supported and latest CUDA drivers)

30 E100, E300 formats Wells closed due to priorities can be opened Assign for well drilling unit number, so all wells with the same number are drilled simultaneously. Use water molar fraction in VFP tables is available Set guide rate at the beginning of each time step equal to the value of group s production rate in reservoir conditions Injection of several passive tracers in one well WELOPEN POPN, param. 2 WDRILPRI parameter 3 VFPPROD WTF, param. 4 GCONINJE VOID, param. 10 WTRACER In dual porosity models set multiplier for matrixfracture transmissibility as one value for all grid or for each grid block MULTSIG, MULTSIGV
