Optical Petrography

At Blackbourn Geoconsulting we are continuously undertaking optical petrography projects, and have an excellent reputation for such work.

We can have thin sections prepared from your rock chips, plugs, or cuttings. We can select suitable samples if required.

We can provide full thin section descriptions, including texture, mineralogy, diagenesis and inferred reservoir characteristics. Brief outline descriptions can be provided as an infill between samples with a full description, or where rapid lithological identification is required.

Modal analysis of detrital grains, authigenic phases and porosity by point counting is available. Long-axis measurement of 100 framework grains can be undertaken to determine mean grain size and sorting parameters. An in-house image anaylsis system allows more complex calculations on grain size, orientation and separation etc.

Please contact Dr Graham Blackbourn to discuss work requirements, without obligation, and to tender for projects.
