William D. "Bill" McCain Jr, Texas A&M: "The Five Reservoir
Fluid Types and their Associated Phase Behavior Patterns"
At the very core of fluids analysis is the determination of the phase
behavior of the fluid, that is, the determination of how the different
or physically distinct parts of the system change and interact with changes
in pressure and temperature. The behavior of a reservoir fluid during
production is determined by the 'type' of fluid and the shape of its associated
phase diagram. Fluid types and behavior should be determined early in
the life of the reservoir, as it is the deciding factor in many of the
decisions which must be made regarding the reservoir. The method of sampling,
the types and sizes of surface equipment, reserve calculations, plan of
depletion and selection of EOR methods are all dependant on the type of
reservoir fluid present. This presentation will cover the 5 reservoir
fluid types and their associated patterns of phase behavior.
Dr. Dave Bergman,
BP: "Investigating the Effects of Oil-Based Drilling Mud on Fluid
of fluid samples from Formation Test Tools by oil-based drilling mud is
a fact of life in today's deepwater sampling environment. Hydrocarbon-based
mud filtrates become dissolved in the naturally occurring hydrocarbons
and thus affect the chemical and physical properties normally analyzed
in typical PVT and fluid testing. An understanding in the chemical and
physical makeup of the pure filtrate base is the first step in correcting
contaminated oil properties to more meaningful, uncontaminated properties.
This presentation will investigate both the chemical and physical nature
of oil-based drilling fluids and provide insights on how they affect the
phase behavior of reservoir fluids.
Brown, ConocoPhillips: "Flow Assurance - A Pi Cubed Discipline"
Flow assurance is production operation that generates a reliable, manageable,
and profitable flow of fluids from the reservoir to the sales point. Flow
assurance is critical for economical production in deep water. The significant
access limits to seafloor infrastructure in deep water (>1,200-ft.
water depth) transform operational problems in shallow-water production
into economic and life-limiting events for deepwater assets. Integration
of discipline interfaces is a key success factor to the diverse and comprehensive
responsibilities of the flow-assurance discipline. It requires the inclusion
of all people involved in the value chain of an asset from operations
support, to contractor, to the scientist. The flow-assurance discipline
drives a new perspective in the approach to reliable production operations.
Its vision goes from reservoir to sales and from concept design to operations.
This presentation introduces a multi-faceted approach to the task of solving
flow assurance issues.
Dr. John Zumberge
and Dr Kevin Ferworn GeoMark Research: "Integration of Geochemistry
and Reservoir Fluid Properties including PVT and Flow Assurance"
The relative quality of newly discovered petroleum is an important
variable with regard to the ultimate quantity produced from a reservoir,
the type and maintenance of production and transport facilities, the net
price obtained for the oil, and environmental costs associated with petroleum
production. The quality of petroleum hydrocarbons are governed by different
geochemical / geological processes including source rock type, thermal
maturity and post-emplacement issues such as biodegradation or mixing.
Recent studies have shown that integrating geochemical groupings and parameters
in traditional engineering correlations significantly improve predictive

William D. "Bill" McCain, Jr.
D. (Bill) McCain, Jr. has been a Visiting Professor in the Harold Vance
Department of Petroleum Engineering at Texas A&M University since
started his engineering career with Esso (now Exxon) Research Laboratories
in 1956, where he assisted in research on surface processing of petroleum
fluids. He was
Professor and Head of the Petroleum Engineering Department at
Mississippi State University fro 1965 to 1976 and taught at Texas A&M
University from 1984 through 1987.
McCain was a consulting
petroleum engineer with Cawley, Gillespie & Associates from 1987 until
1991. He was with S. A. Holditch & Associates from 1991 until 2000,
retiring as Executive Vice President and Chief Engineer. He currently
has his own consulting firm, McCain Engineering. He
wrote two editions of the widely-used textbook, The Properties of Petroleum
Fluids, holds U. S Patents, and has numerous publications in the field
of petroleum engineering. He holds a B.S. degree from Mississippi State
University, and M.S. and Ph.D. degrees from the Georgia Institute of Technology,
all in Chemical Engineering.
Dr. John E. Zumberge
Dr. John E. Zumberge
obtained a B.S. degree in chemistry from the University of Michigan and
a Ph.D. in organic geochemistry from the University of Arizona. He was manager
of geochemistry and geology at Cities Service and Occidental's research
lab in Tulsa prior to joining Ruska Laboratories in Houston. He is presently
vice president and co-founder of GeoMark Research, a Houston geochemical
laboratory and consulting firm since 1991, specializing in crude oil analyses
for determining petroleum systems and oil quality.
Dr. Kevin Ferworn
is a petroleum engineer with GeoMark Research in Houston. He graduated
with BSc., MSc. and PhD. degrees in Chemical and Petroleum Engineering
from the University of Calgary in Canada. Kevin previously worked for
DB Robinson Research and PENCOR, specializing in PVT and Flow Assurance
studies. With GeoMark, Kevin manages the online Reservoir Fluid Database
program and also oversees a new service (PVTMod) that integrates PVT and
geochemistry analyses to conduct real-time fluid property modeling.
Dr. Dave Bergman
Dr Bergman is
a 30 year veteran of the oil industry. He received a BS in Chemical Engineering
from Michigan Technological University and his MS and PhD degrees from
The University of Michigan. He began his career in 1973 as the primary
researcher for the American Gas Association Project, U. of Michigan. In
1976, he joined Amoco Research in Tulsa. During his tenure with Amoco,
he was involved in research into improved viscosity correlations, low-temperature
equilibrium ratios, design of PVT and lab equipment, QA of internal and
external fluid studies and became the Instructor for internal EOS and
PVT courses. Dr Bergman is also the co-author of several published correlations,
including the development of chromatographic methods for C7+ characterization.
In 1999, upon the merger of Amoco with BP, his studies focused on the
development of EOS descriptions for reservoir modeling and QA for outside
testing laboratories. Professionally, he is a member of SPE and the Gas
Dr. Lloyd D. Brown
Dr. Brown's present
emphasis is executing integrated, flow assurance management from concept
to operations and reservoir through sales. Lloyd works in Multi-Discipline
Teams to assist with development and execution of flow assurance solutions.
His work experience includes the North Slope, the North Sea, Indonesia,
and the Gulf of Mexico. Lloyd is presently the Flow Assurance Lead for the
ConocoPhillips' Magnolia project in DW GOM. His experience includes technology,
project and operations functions: Belanak (Indonesia), Britannia (UK), the
West Natuna Gas Pipeline (Indonesia), the InterConnector pipeline (UK),
Heidrun (Norway), Prudhoe Bay (Alaska), Integrated Dynamic Simulator execution,
and Subsea Separation development. Lloyd manages internal and international
resources for project execution and technology development in support of
ConocoPhillips' present and strategic needs for flow assurance execution.
His present technology focus is on execution of integrated dynamic transport-process
control simulation; four-phase transport (i.e. gas, liquid, aqueous, and
solids), and production chemistry management. Lloyd's expertise and networks
include dynamic multiphase transport & process simulation, production
chemistry, chemical treatments, multiphase corrosion/erosion control, and
Dr. Brown has worked
