My name is John & I'm the evaporite expert in the SaltWorks Consultancy Adelaide.  In terms of a home address, I split my time between downtown Bangkok and the coastal region of Adelaide. I have spent more than 30 years consulting to  petroleum and minerals industries, as well as training some of the people who now work in these industries. I hold a doctorate from Flinders University of South Australia and am also a graduate of the University of Adelaide,

2012-Present: Technical studies

I am a senior executive in the SaltWork Consultancy, where my focus is on training and mentoring across various but inter-related technical aspects of saline  geosystems. I also work as an on-site consultant, dealing directly with various problems in evaporite and reservoir geology.

Petroleum Geoscience, Chulalongkorn University

2008-Present: |  Professor

Most of my time at the University is spent in postgraduate teaching or research in rock-based analysis  of  well-logs and seismic, in rock property geology and in applied aspects of modern and ancient carbonate and evaporite geosystems.

Earlier in my career


Before 2006, I was a contract Professor at Universiti Brunei Darussalam. In a former life as a fulltime bureaucrat, I was Professor of Petroleum Geology and Director of the Key Centre for Resource Exploration in the School of Applied Geology at Curtin University in Perth, Western Australia. In the 1980s and early 90s, I was a faculty member of the University of Texas at Austin and the National Centre of Petroleum Geology and Geophysics in Adelaide.

Courses and Training

Evaporite Systems

All the course modules are designed to give the participants an understanding of how various subsurface salts, carbonates and brines are useful predictive tools that, when correctly applied, give a better focus  to exploration and development efforts

Carbonate Reservoir Systems

The course focuses on reservoir quality and its subsurface prediction. To understand the unique nature of wireline indicators in carbonates, the participant must first gain a rock-based understanding of  depositional and diagenetic evolution, within a tectonic and climatic framework.
