About Me
Professional Profile
I am a Reservoir Geologist with over 25 years of research and industry experience. My primary role and interests are characterisation of clastic depositional systems, with a particular focus on reservoir diagenesis and understanding the relationship between porosity/permeability and sediment burial/fluid flow. Emphasis has been placed on the use of multiple datasets to address the issue of reservoir sedimentology and quality, integrating the work of sedimentologists with biostratigraphers, geochemists, petrophysical/reservoir engineers, basin modellers and structural geologists.
Career Summary
April 2006 - Present: Independent Contractor, Bryn-y-Maen, Conwy
​
Outline
As an independent contractor I have provided consultancy services, primarily for the energy sector in New Zealand, but also for local companies in North Wales. I was a researcher for CO2CRC (2004-2015), and have contributed to the development of research programmes for CCS. Over the last 14 years I have additionally led research on the petrographic and inorganic geochemical characterisation of New Zealand reservoirs.
