Core Samples

Sedimentology deals with the physical and chemical changes that occur when sediment is converted into sedimentary rock (a process called diagenesis). By understanding how these rocks were formed, we can work out whether they are likely to contain oil/gas, and if they do, how this is best extracted.

Our sedimentologists use their wide-ranging expertise in both exploration, identifying new opportunities and facilitating predictive modeling, and development & production, undertaking high-resolution reservoir characterization studies. Much of our work is based on close examination of rock material in core, in cuttings or in the field. We have the ability to extract value from these analyses, and integrate with other geosciences to solve even the most complex of problems.
