Jean H. Laherrere
Jean H. Laherrère is a petroleum consultant.
Consulting for "Big Oil"
"Support for a remedial program of oil exploration and development versus switching to research and development of alternative energy sources tends to be found among oil experts who are consultants to the industry. While accepting some of the values of the New Age, they largely remain loyal to their calling as oil geologists and wildcatters. The leading trio of Jean H. Laherrere, Colin J. Campbell, and L.F. (Buz) Ivanhoe have worked for, or with, the leading firm modeling oil fields, Petroconsultants of Geneva. Since the 1950s, they have been fed data on oil exploration and production by just about all the major oil companies, as well as by a network of about 2000 oil industry consultants around the world. They use this data to produce reports on various matters pertinent to the oil industry, which they sell back to the industry." 
"Laherrere's early work on seismic refraction surveys contributed to the discovery of Africa's largest oil field. He retired in 1992 after 37 years with Total CFI and its subsidiaries in exploration activities in the Sahara, Australia, Canada and Paris. Since retiring from TOTAL, Laherrere has consulted worldwide on oil and gas potential and production as a Petroconsultants Associate, and he serves on the boards of the Society of Petroleum Engineers/World Petroleum Congress."
