Data Import

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, use the optional LIS/DLIS add-on module.

Data Processing

Before any form of analysis is performed, the data needs to be processed.

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 time
Corrections of the actual measurements

A number of processing options are available for enhancing the quality of the data. These include

Bad trace interpolation
Amplitude normalization
Despiking filters
Correction of decentralisation
Image orientation

Data Presentation

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 visualized as 3D images using 3D borehole view (ideal to visualize breakouts, well deformation, pipe corrosion).

Data Interpretation

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 rose diagram
