To edit anomalous curve values
using the cross section view When the Z value that appears on the map for an anomalous well is too low or too high something is initially wrong in the data tracking routine or the wrong curve is selected for calculations. You can edit anomalous data points for abnormally low or high engineering values.
To edit anomalous curve values
using the cross section view
1. Find anomalous wells on your cross section and double-click the log.
The Single Well Properties: Shale tab
dialog box appears.
2. Click the tab that corresponds with the active map layer. For example, if your map is NON_SHALE or VSHALE or you think something is wrong with the calculation of Vshale, select the Shale tab.
The Global
Petrophysical Settings dialog box sets a constant shale
line for each well. However, for Cardium, Belly River, and some other
formations an automatic floating shale line may be more effective. To
set an automatic floating shale line, select the float
shale and auto shale
checkboxes and select protected
for both.
Note: If you do not protect individual settings
for a well, the Global
Petrophysical Settings
dialog box overwrites them.
If your current active map is a porosity
map, select the Single Well Properties: Porosity tab
and change the curve or method used to calculate effective porosity.
If your current active map is a saturation
or resistivity map, select the Single Well Properties: Saturation
tab
to find the resistivity log used to calculate saturation. In the use resistivity curve drop–down
box, select other resistivity.
3. Click OK and either press F5, or from the Map menu, select recalculate.
