The Sedimentology unit's expertise extends to both clastic and carbonate facies, and includes the full spectrum of depositional environments, with core examination and fieldwork regularly forming the basis of modelling studies.

  • Core and outcrop description
  • High resolution sequence stratigraphy
  • Reservoir quality (clastic and carbonate including chalky facies)
  • High resolution facies architecture (clastic and carbonate)
  • Petrographic and diagenetic studies
  • Specialist diagenetic studies (SEM, CL, XRD, fluid inclusions
  • Quantitative pore size distribution (image analysis)
  • SGR correlation (GAMMASTRAT™ and GAMMAFACIES™)
  • High resolution core petrophysics — Core-PET™
  • High resolution FMI interpretation and upscaling into seismic
  • Full field correlation input for reservoir modelling
  • Drainage network analysis and hinterland

Well Log Analysis

Robertson offers a comprehensive range of core-related services. Specialist analyses expand the data derived from core, to produce additional information of reservoir heterogeneity and architecture.

We specialise in client-driven problem solving where core description is undertaken with a view to solving specific problems, such as calibrating cores with log analyses and petrophysics. These data are routinely produced as fully digital core description packages.

The detailed visual description of core can be undertaken at any scale requested by the client, normally 1:20, 1:50 or 1:200 scales.

Both clastic and carbonate cores are graphically logged on pre-prepared logging sheets, typically recording lithology (and accessories), grains size and sedimentary structures, macrodiagenetic features, bioturbation index, quantitative ichnofabric analysis, facies analysis/coding, palaeoenvironmental interpretation, hydrocarbon shows, colours, dip data, fracture logging, etc.

Our team of experienced sedimentologists also offer specialist description of horizontal and highly deviated wells as well as integration with FMI/Borehole image logs and conventional wireline logs.
