Borehole image processing

Preparation and processing of borehole micro-imager data — from individual pads to an oriented image suitable for structural and sedimentological interpretation.

Pad handling

• Pad image creation — combine electrodes into per-pad images.
• Speed correction — correct for uneven tool motion.

Harmonisation and equalisation

• Pad harmonisation — harmonise and correct electrodes across pads.
• Histogram equalisation — equalise data arrays for consistent contrast.

Image assembly

• Image assembly and orientation — build and orient the fullbore image.
• Gap filling — fill missing intervals of the image.

Interpretation

• Outputs support bedding, fracture and structural-feature picking from the processed image.
