Geochemical techniques can be used to quantitatively determine the contribution of each of several zones to a commingled oil (or gas) stream. This technique costs less than 2-5% of the cost of production logging. Oil and gas producers can use this technique to:
- Quantify Zone Contributions for Royalty Calculations or Regulatory Requirements.
- Monitor Effects of MBE’s.
- Test if IsoSleeves are Set.
- Control Water Production.
- Monitor Effects of Water or Steam Injectors.
- Optimize Production From Multilaterals.
– Identify Sanded Out Intervals for FCO
– Identify Competition Between Laterals
- Monitor Effect of Initiation of Gas Lift.
Presenter: Dr. Mark McCaffrey
Dr. McCaffrey received his B.A. (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 spent 10 years at Chevron and Arco as a petroleum geochemist, then founded OilTracers LLC. After 10 years, OilTracers was acquired by Weatherford. Mark is a California Registered Geologist (Lic. #5903), a Texas Professional Geoscientist (Geology Lic. #350), a Louisiana Professional Geoscientist (Lic. #264), and an AAPG Certified Petroleum Geologist (Certificate #5339). He is author of numerous articles on the application of geochemistry to petroleum exploration, reservoir management, oil biodegradation, and paleoenvironmental reconstruction.
As an Expert Witness in gas fingerprinting, he has testified (i) in Mississippi State Court, (ii) in Ohio Federal Court, (iii) before the Oklahoma Corporation Commission, and (iv) before the Railroad Commission of Texas. Mark is a PetroSkills Instructor in Oil and Gas Geochemistry, and has taught classes in: Bahrain, Brazil, Colombia, Egypt, England, India, Indonesia, Japan, Jordan, Kuwait, Mozambique, the Netherlands, Saudi Arabia, Tunisia, United Arab Emirates, and the USA. Mark received the 1995 Pieter Schenck Award from the European Assoc. of Org. Geochemists for “outstanding work on biomarkers in relation to paleoenvironmental studies and petroleum exploration.” In 1998, with project team members, Mark received 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 was: 2001-2002 Distinguished Lecturer for the Soc. of Petroleum Engineers; Chairman of the 2002 Org. Geochem. Gordon Conf.; and 2006-2007 Chairman of the Org. Geochem. Div. of the Geochemical Society.
