3DViz Dipmeter

This tool displays dipmeter data on the 3D Module.  This tool displays dip and azimuth as tilted disks along the wellbore.

To display dipmeter data:
  • Click button on the on the Layer Toolbar
  • Select 3DVIZ: Wells > Dipmeter

Dip Log

Selects the dip log in the project.  Petra reads 0 as flat, and 90 as vertical.

Azimuth Log

Selects the azimuth log in the project.

Use Aliases

Enables log aliases for the dip and azimuth log.

Display Depths that are Multiple of

Restricts the discs to only a set depth interval.   Setting this interval to to 50, for example, will only display dipmeter discs every 50'.

No. Of Dip/Azm Samples to Average

Calculates and displays an average of both dip and azimuth around every displayed disc.  This can be useful for displaying data that represents a larger chunk of lithology.  As an example, setting this entry to 10 will average 5 data points on either side of the displayed disc.  This setting will generally depend on the data sample rate and the desired smoothing.  

Size Factor

Sets the size of the dipmeter discs.  The diameter is a multiple of the wellbore diameter.  Setting this entry to 4, for example, will draw dipmeter discs that are 4 times bigger than the wellbores.

Coloring

The 3DViz Module can display dipmeter discs with either a single set color or with a Color bar set by another digital log.

Single Color

Displays dipmeter discs with a single set color.  To change the color, select the button.  

Use Color Curve

Colors dipmeter discs based on another digital log curve value.  Select the desired log curve from the dropdown - note that it can be any digital log curve, not just a dipmeter curve.  

To set a Color bar, select the button. This tool can use either the Normal Colors or Enhanced Colors.
