1.3.1.19 Breakout Log
Description:
BOOK 1 - WELLCAD BASICS - 31
The Breakout log can be used to pick vertical features such as borehole wall
breakouts and tensile fractures interactively from an image. The recorded data is
depth (determined from the center of the picked feature), azimuth (position on the
borehole wall in deg), tilt (inclination of the breakout axis from the borehole axis),
length, opening angle in degree and one or multiple attributes. You can also import
the data from ASCII files.
Data Format:
Depth, Azimuth, Tilt, Length, Opening, Class1, Class2,
Class3…
E.g.
Display Styles:
The data stored in the Breakout Log can be displayed as
Projection Style: A line tracing or polygon framing the breakout as in the oriented
and unrolled image of the borehole wall. The horizontal scale is from 0 to 360 deg.
Symbol Style: The picked breakout is displayed as tadpole. The body of the tadpole
with respect to the horizontal log scale shows the azimuth position. If the tadpole
has been created with a vector line (in ToadCAD) it will indicate the tilt component.
It is optional to display the opening angle as a horizontal bar. Different tadpole
colors and shapes can be used to differentiate between breakout classes.
