5th North American Conference on
Multiphase Technology

Banff, Canada: 31 May - 2 June 2006

    Introduction

    In collaboration with Neotechnology Consultants of Calgary, Canada, and Tulsa University Fluid Flow Program, the Multiphase Conference brought together experts from across the American Continents and Worldwide. BHR Group has been running Multiphase conferences in Europe for almost 25 years and has seen the Technology develop from its theoretical beginnings to its current maturity where it now offers a practical technological solution for many transportation problems. The developments, which have taken place in the oil and gas industry using multiphase solutions, have enabled the industry to improve its production performance, extend its operations and address previously insoluble problems. The lessons learnt, the modelling techniques developed and the practical experiences of its users will be of value to engineers in a range of industries including oil and gas, process, chemicals, mining, water and power industries.

    BHR Group's Conference has been the premier international event providing delegates with the opportunities to discuss new research and developments, to consider innovative solutions and to explore technology transfer between industries. Its technical quality makes this event an essential diary date for all engineers concerned with any aspect of multiphase technology.

    Papers presented at this Conference, as outlined in the contents below, are available in a bound volume of proceedings from Mrs Marian Rolfe at BHR Group Limited.
