Introduction
The decision on whether or not to use multiphase will affect both the economic viability of an asset and its sustainability (i.e. safe and environmentally acceptable design, operation and control). Judging the benefits and risks of a multiphase solution as all or part of a field development scenario needs to balance the technical case with hard evidence of the performance and track-record of systems under field conditions.

Since 1983 the multiphase production conference has followed the development and industrial uptake of multiphase technology, and is in the enviable position of attracting technical experts and innovators together with leaders in application and operation of multiphase production systems. This fusion of leading-edge research and hard-earned practical experience places the conference as a "must" in the calendar for those engaged in the development or application of this technology.
