From discovering oil and gas fields to helping solve major crimes, our Materials Analysis Team makes a significant impact across a range of industrial applications. They work with a variety of organisations in different sectors, conducting bespoke analytical work.
Developing a brand new specialty
We have worked closely with petroleum and oilfield clients for a number of years, and one of the specialties Dr Wray and his team developed is Chemostratigraphy. It is a study of the variation of chemistry within sedimentary sequences. And the method has been developed over a number of years using dissolution and multi-element analysis by either ICP-MS (Inductively Coupled Plasma Mass Spectroscopy) or ICP-OES (Inductively Coupled Plasma Optical Emission).
How it works
The process investigates a sample of rock, soil or other material from the ground, and provides a unique chemical fingerprint or identification. In oilfield applications, this enables Reservoir Engineers to classify and describe in detail the rock and sediment through which they are drilling.
Combining this information with data from other techniques, such as seismology and downhole logging, engineers can map reservoirs, establish flow characteristics and ascertain where to strategically place exploration and production wells.
This technique can also be applied to forensic work to help solve high profile crime cases by characterising samples such as soil and identifying the source of materials through unique chemical profiling.
