What’s New New Flow Assurance Book 

£138UK Pounds

 Flow Assurance is becoming one of the most critical elements in the design and operation of oil and   gas field developments. This is because the flow assurance issues such as hydrates, wax and slugging  etc. have greater potential to occur in deepwater and long distance tie- backs  backs with the necessity to avoid flow path blockages, ensure the integrity of the production system and avoid unstable operating conditions. This requires consideration of these issues in greater levels of detail to enable proper control and management strategies to be developed.  Numerous flow assurance mitigation technologies are being developed by oil operating, as well as contracting companies. The intension of this book is many fold but with the prime objective of providing a reference to

the subject of Flow Assurance associated with the exploitation of oil and gas fields. It is hoped  that the book also provides an understanding  of thefundamentals as well as the state of the current art in Flow Assurance analyses associated with the design and operations of  oil and gas fields in 2011. Where it has not  been possible to provide detailed solution techniques due to the complexity of the mathematics that require require iterative computational techniques, simplified equations have been identified to enable a first order  estimate solutions. This book can be used by  both graduate and post graduate students,  practicing process engineers and engineers in other disciplines that require an understanding of Flow Assurance, associated with reservoir  oil and gas production, as well as lecturers in advanced study courses associated with academic training.

The book is structured to provide: Flow Assurance for transporting reservoir production fluids between the reservoir and the host  processing facility as well as providing providing the basics of oil and gas reservoirs and host processing facilities. Flow Assurance is defined, Reservoir production fluids discussed, Economics considered and host processing facilities options presented. Flow Assurance issues that are confronted in the development of oil and gas reservoirs/fields are evaluated in detail as well as methods presented to assist in the design and operations of  systems such as: o Production wells, manifolds, flow lines, pipelines and risers for subsea fields as well as onshore field development and operation for the life of these fields. A practical case study in the development of o f flow assurance methods for an oil field is also included in this book. It is hoped that this case study illustrates the application of flow assurance solution methods as guidance for practicing engineers, project managers and investment institutions or individuals that are involved directly or indirectly in the exploitation of oil and gas fields either onshore or offshore.

The complexities of multiphase flow have been discussed along with the evaluation of each of  the main flow assurance issues that are required for the design and operation of the transportation systems. Subsea technologies that provide the economic value for offshore reservoir exploitation have  been summarised. A chapter dedicated to reducing the environmental impact of releasing hydrocarbons into the atmosphere.

 It is hoped that the readers of this book enjoy the scientific scientific and engineering methodologies presented  in the required flow assurance philosophies for the safe and e conomic exploitation of oil and gas  fields and the associated environmental pollution reductions. Further Further that, young engineers can take  some of the ideas presented and develop new innovations to take the energy sector well into the 21 st  century.  Dr. The Au thor. Dr.
