Stage Table Groups
Geometry
Stage: Stage Number
Toe MD (ft or m): MD depth defining the toe-ward most extent of the Stage: Usually the MD depth of the bounding Toe-Plug
Heel MD (ft or m): MD depth defining the heel-ward most extent of the Stage: Usually the MD depth of the bounding Heel-Plug
Mid MD (ft or m): Calculated mid-Stage MD depth
Length (ft or m): Calculated distance between the Toe MD and Heel MD inputs
TVD (ft or m): Calculated true vertical depth of the wellbore at the mid-Stage MD depth
Lithology Info
Defined by the associated geosteering interpretation
Percent in Zone (%): The percent in Target Zone of each stage based on the assigned geosteering interpretation.
Formations: The list of formations each stage touches in based on the assigned geosteering interpretation.
Lithology (text, %): The weighted percent lithology each stage based on the assigned geosteering interpretation. The 'Lithology Type' needs to be set in the associated 'Stratigraphic Column' for this to calculate.
Faults (Num, (ft or m)): Calculated number of faults per stage and the total throw on those faults. Ex: 2 (15), would mean two faults with a combined 15 feet of throw.
Avg TVD to Target Top (ft or m): Calculated average distance from the average TVD point along the stage to the top of the target zone.
Max TVD to Target Base (ft or m): Calculated maximum distance from any TVD point along the stage to the top of the target zone.
Avg TVD to Target Top (ft or m): Calculated average distance from the average TVD point along the stage to the base of the target zone.
Max TVD to Target Base (ft or m): Calculated maximum distance from any TVD point along the stage to the base of the target zone.
Drilling Info
GR gAPI: Calculated average gamma ray
ROP (ft/h or m/hour): Calculated average rate of penetration
WOB (lbft or N): Calucated average weight on bit
GAS (%): Calculated average gas
MSE (MPa): Calculated average mechanical specific energy
Avg Dogleg Severity (dega/ft(100) or dega/m(30)): Calculated average dogleg severity
Max Dogleg Severity (dega/ft(100) or dega/m(30)): Calculated maximum dogleg severity
Selection of logs for average Drilling Info per stage: ZoneVu selects curves from the Target Wellbore’s logs, not from the Type Wellbore. When more than one Target wellbore log file contains a matching curve, the system gives priority to splice composites, then curves from the same LWD file used for steering, then Target Well RigStream Log and finally Target Well LAS Logs.
Petrophysical Info
Phi (%): Average Porosity
Sw (%): Average Water Saturation
Vsh (%): Average Volume of Share
SoPhiH (%): Average of the value representing the Oil saturation x Porosity x Thickness
Adding average petrophysical data: Average petrophysical data can be imported using the Frac Import spreadsheet. ZoneVu can also do a weighted calculation if there is has been petrophysical information including in the Tops data for the Type Well used in the associated geosteering interpretation. See How to Import Well Tops.
User Curves
The per stage average of any log curve available in scene control can be added to the Frac Stage Table. The units for the User Curves are taken the curve header. See User Curves: Sampling log data to the Frac Table

User-Defined columns
ZoneVu Frac allows for the import of up to five User-Defined Columns populated with integer data (Numbers with decimals). ZoneVu Frac will update the Column Names in the Stage Table with any text added after the bar "|" in the header. For example, if User Defined Column #1 has a header of "User1| Acid Volumes", after import, User-Defined Column #1 in the Stage Table will be renamed "Acid Volumes"
See User-Defined Columns in ZoneVu Frac
Notes
Every stage in a frac has a 'Notes' column at the end of the Stage Table. This column can contain any information.
Export Frac Stage Table
ZoneVu 'Frac Stage Tables' can be exported as Excel Workbooks from the 'Frac Stage Table', as well as from the 'Frac Plans and Jobs' list.
Importing Frac Stage Table
See How to Import Frac Data and Appending New Data to an Existing Frac
Stage Table Units
Units for standardized data columns: Units the columns of the stage table can be imported. Each import spreadsheet should contain either all metric or all US units.
Use the 'Display Settings' button in the 'Main Button Tree' of the Viewer to change the 'Display Units' to US or Metric. This option is located on the 'General' tab of the 'Display Settings' dialog.
Units for Users Curves: The units for 'User Curves' will come from the log curve header information.
Units for User-Defined Columns: the units for 'User-Defined Columns' can be selected by the user for each column via the User-Defined Columns Manager. See User-Defined Column Manger
