8th International Conference
Multiphase '97
How deep? How far? How Soon?

Cannes, France: 18-20 June 1997

Multiphase exploitation of marginal and deepwater oil reserves had long been needed. Significant research is leading to improved understanding of this beneficial technology and for 14 years this Conference has followed the development of multiphase technology reporting how industry's needs have influenced it. From research to products, it brought together people who shape the way the technology is developed or who want to understand what it offers, by providing a unique forum for exchanging ideas and information.


The Conference Proceedings can be purchased from: Mrs Marian Rolfe. For more information on future events in this series, please see our Events List or contact Mrs. Catriona Rolfe. The proceedings containing the following papers.
