Image Analysis, Porosity and CL Studies

Ties Geology to Petrophysics and Assists Reservoir Modelling

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

• 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
