Fluid contact data from a region attribute table cannot be used in Volumetrics if defined with a template based on standard contacts.
False
Variables used as input to volume calculations can only be specified through constant values.
False
Users cannot specify variables by selecting a variable class, specific variable, and subsets for which different variable values are given.
False
Variable types include oil, gas, and formation variables, each with specific variables and unit measures, defined through the Unit Set Selector in the Tools menu.
True
In the Report file tab, users can only specify the output as a Report file, and not a Report table data object.
False
Associated gas and liquid units in the Report file and table are linked to the units set for STOIIP and GIIP respectively, which are not specified in the Unit Set Selector dialog box accessed from the RMS menu bar under Tools.
False
Maps cannot be output to specific folders in the Data tree including Model QC, General 2D data, Clipboard, and Zones.
False
Input variables for select volumes are entered in the Variables tab, depending on the options selected in the Calculations tab.
True
The Variables tab lists the formulas to be used for selected calculations, with options independent of the input and calculations chosen in previous tabs.
False
Users cannot specify variables by selecting a variable class, specific variable, and subsets for which different variable values are given.
False
Variables used as input to volume calculations can only be specified through constant values, and not through surface or parameter selection.
False
The volumetric units used are in the Reservoir engineering category.
False
In volumetrics calculations, GOR is dimensionless.
True
The Report file can only be specified as a Document list.
False
Document list output is a text file with a separate file for each realization.
True
Tabular output is presented as an Excel, CSV, or text file with a separate file for each realization.
True
Options such as including realization number in file name cannot be toggled.
False
The order of volume calculations in the Report file cannot be set based on the subsets specified.
False
The Report table option creates a table within RMS with results for all realizations.
True
The Volumetric Table Viewer dialog box consists of four tabs: Data selection, Statistics, Raw data, and Visualization.
False
P10 and P90 values in the Statistics tab reflect high and low side estimates, respectively.
True
Raw data tab presents the calculated volumetric data in a table, accounting for potential undefined values if the job is run for fewer realizations than set for the project.
True
Before running the job, ensure the required Import/Export unit set has been selected for the report output.
True
The main types for volumetrics calculations include Oil/Condensate, Gas, and Water.
False
The formulas used for volumetrics calculations involve variables like porosity, water saturation, and recovery factors.
True
Three outputs can be selected for each volumetrics calculation: Parameter, Zone map, and Total map.
True
Pre-calculated bulk volume cannot be used to speed up later calculations.
False
Area and average thickness can be generated per license boundary only, not per zone.
False
Negative cell volumes can be set to zero but not allowed, providing a choice to check the results.
False
Map layout can be defined by dragging a surface into the Map Layout drop site.
True
To use license boundaries, an open, collapsed polygon must be present.
False
Discrete fluid parameter can be created to describe fluid contact in the grid model.
True
Output location for all the maps selected in the Subtypes section cannot be specified.
False
Subtypes for volume calculations include Bulk, Net, Pore, HCPV, STOIIP, GIIP, and Recoverable.
True
Selecting a grid parameter defining facies is not necessary for Volumetrics Calculation in RMS Software.
False
