12th International Conference on
Multiphase Production Technology '05

Barcelona, Spain: 25 - 27 May 2005

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.

Introduction

The Technical Committee of the 12th International Conference changed the way this prestigious event was structured for their 2005 Conference.

As corporate structures change, two distinct groups of specialists charged by their organisations to provide expertise on a wide range of technical problems associated with Multiphase Production Technology have emerged.

Some specialists have worked for many years in this field amassing considerable knowledge and experience. The industry looks to these people to keep the technology developing through the adoption of novel operational solutions and innovative techniques based upon sound knowledge and experience. Papers, presentations and networking from this conference over the years have built upon this reservoir of practical capabilities.

In recent years many young engineers have joined the industry, having been trained in the very latest techniques and are now eager to contribute to technology development. They need to understand quickly and effectively what is the current state of the art in key areas of the technology. Answers to the questions: What can be done now? Who are the leaders in each area? Where can I go to learn this knowledge? are just some of the questions which have been posed and which the Committee hope to answer at this Conference.

The themes for the Conference were:

  • Laboratory and Field Measurement and Analysis
  • Modelling and Simulation
  • Process, Measurement and Control Equipment
  • Production Chemistry
