Retired petroleum geologist and executive

After taking a degree and a PhD at Oxford, he joined the oil industry as a field geologist, working in Trinidad, Colombia, and Papua before moving into a more executive role in New York, Chicago, Ecuador, London, Dublin, and Norway, working for both major and independent companies.
