Dr. John M. Williams holds B.Sc. and Ph.D. degrees from the University of Exeter (1974, 1979) where his doctorate was awarded for phase equilibrium studies of high pressure systems. He subsequently gained more than 20 years of oil industry experience with Shell, the Schlumberger Group, Saudi Aramco, and in operating his own consulting company Science Support Services. Dr. Williams has led R&D projects involving sampling, PVT, and analytical techniques, and has written both patent and research publications. He has set up and managed commercial PVT operations and has gained field experience in many countries. Dr. Williams was largely responsible for the recent API RP-44 sampling procedures industry standard, and has written a chapter on the same subject for the SPE Petroleum Engineering Handbook. At the PI, Dr. Williams has created and taught numerous new engineering courses, started the PI SPE Student Chapter, chaired the PI’s HSE committee and assisted with PE program accreditation activities. His research interests involve the use of new sampling methodologies, the enhancement of laboratory data quality and applicability to field needs, and petroleum engineering pedagogy.
