Borehole Image Analysis

Image Data QC

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 Processing

Image Data interpretation

Image Data Processing

  • BRG provides standard image data processing, including speed correction, button and image equalization, static and dynamic normalization, and depth matching for any available tool on the market.  
  • We are neutral to data acquisition vendors.

Image Data interpretation

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.​
