Présentation en anglais
Fluids produced from hydrocarbon fields are composed of a mixture of oil,
gas and water, often with corrosive components, sometimes laden with solid
particles, and are a potential source of many flow instabilities. Frequently, they
are now directly exported long distances, in multiphase conditions, towards an
existing processing facility or a new processing centre created to serve simultaneously
several new fields. This production scheme, which is especially applied
offshore, in mature basins such as in the North Sea or in the Gulf of Mexico
where infrastructure exists over large areas, can also improve the economics
of small or deepwater fields.
This book presents the fundamentals of multiphase production with regard to
flow simulations in multiphase pipelines, multiphase pumping and multiphase
metering. It gives first a description of the multiphase flow patterns that may
appear in a pipe and explains how they are managed by the models. It also
offers a good introduction to modelling of hydrodynamic effects, thermodynamics
and thermal exchanges.
Multiphase pumps are now deployed in fields, whether onshore, offshore or
subsea, all over the world, where natural reservoir pressure is insufficient. The
book presents the various multiphase pump concepts and explains their operating
principles and how they can be introduced into a production system.
An adequate instrumentation system is needed to monitor and control the
performance of such systems and multiphase meters are increasingly used in
place of conventional test separators, both offshore and onshore. This book
provides the basic principles of multiphase metering, which relies on a combination
of elementary measurements, and particularly the means to meter the
oil, gas and produced water flowrates in multiphase conditions.
The successful application of long-distance multiphase transportation, multiphase
pumps and meters has paved the way for the development of subsea
processing, presented and discussed in the last chapter which deals with new
areas such as subsea separation, subsea gas compression, energy recovery
with a multiphase turbine, etc.
This book gives a large range of information on approaches and technologies
which can be used today. It is designed for engineers involved in field development,
but also for petroleum engineering students.
