Image Analysis, Porosity and CL Studies

Ties Geology to Petrophysics and Assists Reservoir Modelling

Petrological Microscope

Image Analysis (IA)

  • Acquisition, pre-processing and supervised porosity classification
  • Percentage porosity over a range of scales (SEM, optical microscopy, whole t-section, core, outcrop etc).
  • Calibrated images generate real measurements for Pore Size Distributions (PSDs)
  • Can be amalgamated yielding a Combined Pore Size Distribution
  • 3D presentation of data for ease of sample comparison
  • Pore Geometries for further comparison of reservoir samples
  • Proportions of Matrix, Vug and Fracture porosity
Cathodoluminescence (CL) Equipment

  • Technosyn 8200 Mk 5-1 automatic CL combined with Integrating Colour Camera (Low Light Sensitive).
  • Nikon Eclipse LV100 petrological microscope for CL, PPL, XPL and Reflected Light microscopy
  • Set-up suitable for a range of carbonates (limestone/dolomite) clastics (e.g. sandstones/arkoses)

Cathodoluminescence (CL) Analysis

  • CL cement stratigraphy of reservoir formations
  • Cross-cutting relationships of fracture fills allow relative fracture timing
  • Combined with Fluid Inclusion data enables temperature of emplacement/reservoir fluid evolution
  • Coupled with Microprobe element mapping enables identification of critical diagenetic changes
  • Easy identification of stylolites and stylo-fractures
