Detailed logs of the imager data can be produced at any vertical scale. The image of the borehole wall is presented in an unwrapped form with a horizontal scale marked 0°, 90°, 180°, 270° and back to 0°.
Structural features and discontinuities are picked from the images in the form of colour coded sinusoidal projections: blue – fractures; red – bedding/ fabric features; green -veins). This structural log is presented as ‘Discontinuities’ with a horizontal scale as the image data.
Using the borehole diameter, dip and azimuth along with the geometric parameters of the sinusoids, the true azimuth and dip of the discontinuities are calculated and presented as a “tadpole” plot. The true dip data can then be used.
Additionally, rose diagrams and stereo-nets of the discontinuities can be produced.The plots can then be transferred into various electronic formats.
