Borehole image analysis (PDF)
Borehole image data from a variety of tools including acoustic
televiewer, optical televiewer, corescanned images, FMI, FMS,
CAST, CBIL, UBI and STAR and Sondex MIT are supported.
For data available in LIS/DLIS format files, you will have to
use the LIS/DLIS add-on module.
Before any form of analysis is performed, the data needs to be
This involves the creation of a reliable high quality image from
raw tool measurements. It consists of a number of procedures.
• Log quality control
(check both image and orientation measurements)
• Reconstruction of
the data for variation in tool properties or at acquisition
of the actual measurements
A number of processing options are available for enhancing the
quality of the data.
• Bad trace interpolation
• Amplitude normalization
• Despiking filters
• Correction of decentralisation
• Image orientation
Data can be
displayed as an image (user definable image color palette),
as curves (shifted or stacked curves) or as 3D cylinder
display (mimic a virtual core)
Data can be visualised as 3D images using 3D borehole view
(ideal to visualise breakouts, well deformation, pipe corrosion)
Any number of sinus curves can be interactively picked recording
azimuth and dip values.
Each pick can be qualified into user definable categories (ToadCAD)
Picks can be displayed as sinus, tadpole or stick plot.
Fully interactive structure interpretation including polar and
