    DR. MARK MCCAFFREY received his BA (1985) from Harvard University, magna cum laude with highest honors in geological sciences, and his PhD (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, a firm specializing in applications of petroleum geochemistry. After 10 years, OilTracers was acquired by Weatherford. Mark is a California Registered Geologist (License #5903), a Texas Professional Geoscientist (Geology, License #350), 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 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, Saudi Arabia, Tunisia, United Arab Emirates, and the USA. 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, 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 lectured in 17 countries as the 2001-2002 Distinguished Lecturer for the Society of Petroleum Engineers; he was Chairman of the 2002 Organic Geochemistry Gordon Conference, and 2006-2007 Chairman of the Organic Geochemistry Division of the Geochemical Society. He was the 2014 recipient (as coauthor) of the AAPG Energy Minerals Division President's Certificate for Excellence in Oral Presentation, and was the 2015 recipient (as coauthor) of the AAPG Bernold M. "Bruno" Hanson DEG Excellence of Presentation award.

  • Course Content
During field development and production, numerous problems can be solved through integration of geochemical, geological, and engineering data. Geochemistry and geochemical approaches for solving these problems are appealing for several reasons.

1) They provide an independent line of evidence that can help resolve ambiguous geological or engineering data. Example: geochemical data can reveal whether small differences in reservoir pressure reflect the presence of a barrier between the sampling points.

2) They are far less expensive than engineering alternatives. Example: geochemical allocation of commingled production costs only 1-5% as much as production logging.

3) They have applicability where other approaches do not. Example: geochemical allocation of commingled production can be performed on highly-deviated or horizontal wells and on wells with electrical submersible pumps - well types not amenable to production logging.

This course explains how geochemistry complements other reservoir management tools. Case studies and exercises illustrate key points. Computer-based exercises illustrate the utility of certain key software packages. Sampling pitfalls and sources of contamination are discussed. The course will NOT cover PVT (Pressure-Volume-Temperature) relationships or equation of state calculation. One personal computer is provided, at additional cost, for each two participants.
Development geologists, petroleum engineers, managers, and technical personnel.
How To:
  • Use mud gas isotopes to identify and characterize pay zones
  • Use the geochemistry of produced fluids (oil, gas, water) and/or core material to: identify missed pay, assess reservoir compartmentalization, allocate commingled production, identify completion problems (tubing leaks, poor cement jobs, etc.), characterize induced fractures (e.g., fracture height), monitor the progression of floods (water, gas, or steam), predict vertical and lateral variations in fluid viscosity and gravity, and identify the geological processes which control fluid properties in a given field
  • Use certain key software packages (including, PeakView, ReserView, OilUnmixer, Excess Pressure calculations, etc.)
  • Using fluid compositions as natural tracers for tracking fluid movement and compartmentalization
  • Understanding processes that cause compositional differences between fluids (e.g., differences in source facies, source maturity, biodegradation, water washing, evaporative fractionation, etc.)
  • Integrating geochemical, geological, and engineering data to identify missed pay, characterize reservoir compartmentalization, allocate commingled production, identify well completion problems, predict fluid viscosity/gravity, and monitor floods
  • Basics of oil, water, gas, and mud gas compositional analyses
