Using Petroleum Geochemistry to Solve Field Development and
Production Problems
Dr. Mark A. McCaffrey
ABSTRACT: During field development and production, a variety of
common problems can be solved through integration of geochemical,
geological, and engineering data. For example, such studies can
identify reservoir compartmentalization, allocate commingled
production, identify completion problems (such as tubing string
leaks, or poor cement jobs), predict fluid properties (viscosity,
gravity) prior to production tests, characterize induced fracture
geometries, monitor the progression of floods, or explain the
causes of produced sludges. For each of these applications,
geochemical approaches are appealing for three reasons:
- Geochemistry provides an independent line of evidence that can
help resolve ambiguous geological or engineering data. For example,
geochemical data can reveal whether small differences in reservoir
pressure reflect the presence of a no-flow barrier between the
sampling points.
- Geochemical approaches are commonly far cheaper than
engineering alternatives. For example, geochemical allocation of
commingled production can be achieved typically for only 1-5% of
the cost of production logging.
- Geochemical approaches have applicability where other
approaches do not. For example, geochemical allocation of
commingled production can be performed even on highly-deviated or
horizontal wells, and even on wells with electrical submersible
pumps - well types not amenable to production logging.
This presentation will discuss these applications of
geochemistry, and will highlight how geochemistry complements other
reservoir management tools. A variety of case studies will
illustrate key points. In addition, sampling pitfalls and potential
sources of contamination will be addressed.
Biography of instructor:
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 geochemistry from the Massachusetts Institute of
Technology. Mark is a California Registered Geologist (License
#5903) and an AAPG Certified Petroleum Geologist (#5339). Author of
26 articles, Dr. McCaffrey 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." After 10
years at Chevron and Arco, Mark co-founded OilTracers, L.L.C.
(www.oiltracers.com), a firm specializing in the integration of
geochemistry, geology and engineering data to solve a variety of
oil exploration and production problems.
About OilTracers
OilTracers is a petroleum consulting company that specializes in
integration of geochemical, geological, and engineering data to
solve various petroleum exploration, development, and production
problems. In addition, OilTracers owns and operates the two premier
petroleum geochemistry web sites (www.oiltracers.com and
www.gaschem.com) The databases on these web sites, such as OilRef
(a database of >14,000 petroleum geochemistry citations), the
Oil Sample Library (a listing of >33,500 oil geological samples
owned by various laboratories), and the Petroleum Geochemistry
Dictionary provide answers to more than 5,000 inquiries a month.
OilTracers is organized very much like a law firm, with our various
scientists having complementary areas of expertise. OilTracers is
not a laboratory. We do no analyses. We only interpret data. All
oil analyses are contracted to one of several laboratories we use
around the world. These laboratories then transfer the data
electronically to OilTracers for interpretation.
