Borehole Image Analysis

Image Data interpretation

Image Data Processing

Borehole image data is technically complex and a proper quality control step to identify any data issue prior to image data processing is very important. BRG uses industry-standard software to fix data issues where possible or to flag zones where data problems are unfixable to avoid misleading applications.

Image Data interpretation

Image Data interpretation

Our image data interpretation covers from structural analysis, sedimentary analysis, reservoir heterogeneity analysis to fracture characterization;
Our expertise ranges from alluvial, fluvial, deltaic, shallow marine to deep-water clastic reservoirs, carbonates as well as unconventional shales gained from both domestic and internationally.

Structural dip analysis

Natural fractures & faults

Image Data interpretation

Structural domain analysis
Structural dip determination
Sub-seismic fault interpretation based on images and/or observation of bedding drag plus damage zones, i.e. breccia and fractures, etc.
Near-wellbore structural cross-section generation
Structural uncertainty can significantly be reduced using near-wellbore high-resolution structural dips and fault data to calibrate the seismic structural interpretation.

Sediemntary analysis

Natural fractures & faults

Natural fractures & faults

Sedimentary structures and rock texture interpretation using borehole images
Facies analysis integrating lithology data from open-hole logs, sedimentary features, and textural info extracted from image logs;
Paleo-current analysis (structural dip removal is often needed)
Core and outcrop data, if available, can be very useful to be integrated with the borehole image-based sedimentological interpretation with more accurate results.
