HYDROCARBON CHARACTERISATION

Bulk composition, sulphur, wax content, pour point, asphaltene content, salt-in-crude

Wax charaterisation by high temperature GC

Monitoring the use an effectiveness of oil field chemicals (PPD, de-emulsifiers)

Refinery charcterisation by simulated distillation, calorific value

RESERVOIR CONTINUITY STUDIES

High resolution gas chromatography for ‘star’ diagrams of compound ratios and isotopes

Proving lateral fault block and sand body continuity

Proving vertical connectivity of fractures or lateral extent of shale/limestone breaks

Thermal vaporisation of hydrocarbons and GC in core samples where tested oils are no longer available

Using this expertise in field unitisation disputes as expert witnesses
