Volumetrics Calculator: Start Page
The Volumetrics Calculator calculates the volume of recoverable hydrocarbons. The application behaves similar to a spreadsheet, allowing inputs to be entered at each step of the calculation, and providing output for intermediate results, as well as the final result.
How
do I perform a volumetrics calculation?
-
Choose the method you will use to calculate the gross pay rock volume, and the units of measure to be used for inputs and outputs in the calculation.
-
Select structural components of the volume, or a thickness grid and/or enter numbers to calculate the gross pay rock volume.
-
Adjust the ratios in the calculation, or override the intermediate volumes.
-
Save calculation results or inputs so that they may be used in the project, reloaded at a later time, or imported into a spreadsheet.
General Information
Question: How do you want to specify the Gross Pay Rock Volume?
Choose
one of the three options to determine how
Each choice
will cause a difference form to display for the second stage of the
calculation, on the Structure page of the wizard.
By selecting top and base grids, oil/gas contact and hydrocarbon/water contact in subsea values: All structural details may be entered, including inclusion and exclusion polygons, top and base grids, and contact values on this structure page.
By selecting a thickness grid: A thickness grid may be selected, along with optional inclusion and exclusion polygons on this structure page.
By entering the volume directly: The Gross Pay Rock Volume may be entered as a number, or calculated from the Gross Pay Area and Average Thickness fields on this structure page. In addition, for this option only, ratios on the Parameters wizard page will only be entered as numbers, not as grids.
Units of Measure
Input
Specify
the units for the input
grids.
Grid Surface Units: Shows the surface unit of measure applied to grids, as determined from the project coordinate system.
Grid
Depth Units:
Shows the depth unit of
measure for grid and
contact values, as
determined from the project setup.
Output
Specify
the units
for
the results.
Gross Pay Area Units: Select the unit of measure for entering and viewing Gross Pay Area values.
Average Thickness Units: Select the unit of measure for entering and viewing Average Thickness values.
Rock Volume Units: Select the unit of measure for entering and viewing Gross Pay Rock Volume and Net Pay Rock Volume values.
Hydrocarbon Volume Units: Select the unit of measure for entering and viewing hydrocarbon volume values.
