9th International Conference
Multiphase Technology
Frontier Technology Comes of Age

Cannes, France: Banff, 16-18 June 1999

The proceedings of this Conference can be purchased from Mrs. Marian Rolfe at BHR Group Limited. For more information on future events in this series, please see our events list, or contact Mrs. Catriona Rolfe.

The oil and gas industry continues to increase its practical applications for multiphase technology as the concepts becomes more accepted. In particular, the economic benefits for developing marginal and deep water oil fields using multiphase techniques are now established. Current oil price levels and the need to develop these fields should drive the application of multiphase technology even further forward.

The potential advantages of multiphase over conventional techniques, in terms of capital benefits and cost savings, are dramatic. One major oil company recently claimed to have saved $10s of millions simply through the introduction of multiphase metering, recouping their R&D investment in metering on one development alone.

Significant research into the complexities of multiphase technology has led to more effective design of facilities for long distance multiphase transportation and the equipment used for pumping, metering and processing.

Despite the dramatic progress that has been made, challenges remain. For example, deep water, riser motion and low temperature environments are a few which present particular problems and for which new solutions are needed.

Filling the Knowledge Gap

Lack of information and understanding help fuel resistance to progress. This will only be overcome when multiphase is seen as a viable solution to requirements in the field.

Multiphase '99 was designed to provide oil and gas industry managers with the information they need to decide how and when multiphase technology can be best employed. The conference aims to lead the industry through these first steps by promoting greater understanding of the potential advantages and risks involved. The business, economic and technical rewards are there for those organisations who continue to extend the boundaries of the technology.
