Hi, I'm John, and I manage technical services at SaltWork Consultancy. My interest in evaporitic systems drives me to write these articles. With over 30 years of experience in saline systems, I focus on the applied aspects of carbonate-evaporite interactions. Additionally, I compile the SaltWork GIS database and have authored several books and scientific papers on evaporites and saline geosystems.

In my previous career as a full-time academic, I often encountered the pettiness and inefficiencies that come with overpaid, underworked educational bureaucracies in Western universities. The pervasive herd mentality became a significant time drain, leading me to resign from academia.

Now, I prefer to live and consult by the coast in Adelaide, Australia. I also work part-time as an academic in Southeast Asia each year, where I appreciate the people's "can-do” attitude. Throughout the years, I have consulted on various issues related to saline rock and carbonate reservoir characterisation in hydrocarbon and base metals exploration.

I also conduct training programs linked to my consultancy. My past clients include INPEX, MMG, Chevron International, Exxon International, BHP Billiton Resources, BHP Billiton Petroleum, Homestake, Pasminco, Shell International, Statoil, PTTEP, ADNOC, Saudi Aramco, Nexen, NIOC, VPI, and others.
