43 Questions
True or false: The Volumetrics dialog box has three tabs: General Tab, Calculations Tab, and Variables Tab.
False
True or false: A job can only be specified to perform volume calculations and report on the entire grid model.
False
True or false: The Region Index in the General tab allows the selection of discrete parameter defining a region partition.
True
True or false: The use of region models in RMS is not explained in the Working with Regions page.
False
True or false: If you click Save in the Volumetrics dialog box, it will immediately run the job for the current project realization.
False
True or false: If you requested a report file and the specified volumetrics report file already exists, a warning message will be displayed asking if you want to overwrite the previous report file.
True
True or false: RMS calculates the volumes and displays a progress indicator pop up box when you run the Volumetrics.
True
Map increment option allows users to adjust grid resolution for output maps, with a larger value providing more accurate maps but slower calculations.
False
Fluid contact data from a region attribute table can be used in Volumetrics if defined with a template based on standard contacts.
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 can specify variables by selecting a variable class, specific variable, and subsets for which different variable values are given.
True
Variable types include oil, gas, and water variables, each with specific variables and unit measures, defined through the Unit Set Selector in the Tools menu.
False
Variables used as input to volume calculations can only be specified through constant values, not surface or parameter selection.
False
In the Report file tab, users can only specify the output as a Report file, 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 specified in the Unit Set Selector dialog box accessed from the RMS menu bar under Tools.
True
Maps can be output to specific folders in the Data tree including Model QC, General 2D data, Clipboard, and Zones, with the latter requiring a network structural framework for grid model based output.
True
Input variables for select volumes are entered in the Variables tab, depending on the options selected in the Calculations tab.
True
Variables can be defined for each zone, region, or as a single value for all zones and regions through three alternative input sources: Panel, Table, and Region model.
True
Variables used as input to volume calculations can be specified through constant values, surface or parameter selection, or by using a table with the same format as specified in the Table Link section of the Volumetrics dialog box.
True
Is it necessary to have a closed, non-collapsed polygon for using license boundaries in volumetrics calculation?
True
Can negative cell volumes be set to zero or allowed in volumetrics calculation?
True
Are there four main types for volumetrics calculations?
False
Can pre-calculated bulk volume be used to speed up later calculations without any constraints?
False
Can area and average thickness be generated per license boundary or per zone?
True
Is a discrete fluid parameter used to describe fluid contact in the grid model?
True
Can the map layout be defined by dragging a surface into the Map Layout drop site?
True
Is it possible to select only one output for each volumetrics calculation?
False
Are recovery factors not used in the formulas for volumetrics options?
False
Are there six subtypes for volume calculations?
True
Can the output location for all the maps selected in the Subtypes section be specified?
True
Is it necessary to use a specific formula for volumetrics calculations involving variables like porosity, water saturation, and recovery factors?
True
In volumetrics calculations, GOR is dimensionless.
True
The Report file can be specified as Document list or Tabular layout.
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 and exporting parameter units to file can be toggled.
True
The order of volume calculations in the Report file can be set based on the subsets specified.
True
The Report table option creates a table within RMS with results for all realizations, useful for investigating uncertainty.
True
The Volumetric Table Viewer dialog box consists of three tabs: Data selection, Statistics, and Raw data.
True
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 volumetric units used are in the Volumetrics category, not the Reservoir engineering category.
True
Document list output is a text file with a separate file for each realization.
True
