Dr. McCaffrey received his B. A. degree (1985) from Harvard University, magna cum laude with highest honors in geological sciences, and his Ph.D. (1990) in chemical oceanography in the area of organic geochemistry from the Massachusetts Institute of Technology/ Woods Hole Oceanographic Institution Joint Program.  Mark is a California Registered Geologist (License #5903), a Texas Professional Geoscientist (License #350), and an AAPG Certified Petroleum Geologist (Certificate #5339).  He is a senior or co-author of numerous articles on the application of geochemistry to petroleum exploration, petroleum reservoir management, oil biodegradation, hazardous waste remediation, paleoenvironmental reconstruction, and marine chemistry.   Mark was the 1995 recipient of the Pieter Schenck Award from the European Association of Organic Geochemists for “outstanding work on biomarkers in relation to paleoenvironmental studies and petroleum exploration.”  In 1998, Mark received (with project co-workers) the Arco Award of Excellence “for developing a new charge and migration model for the Brookian petroleum system, allowing improved charge risk assessment for prospects on the Central North Slope of Alaska”.  Mark spent 10 years at Chevron and Arco integrating geochemistry, geology and engineering data to solve a variety of oil and gas exploration and production problems.  In 1999, Mark then co-founded OilTracers LLC (www.oiltracers.com), a firm specializing in this type of work.  In 2010, OilTracers was acquired by Weatherford Laboratories. Mark was a 2001-2002 distinguished Lecturer for the Society of Petroleum Engineers in 17 countries, and was the Chairman of the 2002 Organic Geochemistry Gordon Conference.  Mark was Chairman (2006-2007) of the Geochemical Society Organic Geochemistry Division, and is a PetroSkills Instructor in the area of Oil and Gas Geochemistry (and has taught classes in: Bahrain, Brazil, Colombia, Egypt, England, India, Indonesia, Japan, Jordan, Kuwait, The Netherlands, Mozambique, Tunisia, United Arab Emirates, and The United States).  For litigation projects, Dr. McCaffrey has been has testified in Federal and State court as an Expert witness in gas Fingerprinting.
