Today’s increasing demand for energy calls for a number of different measures to be taken in oil and gas production. The past has seen a considerable number of wells having been shut-in due to poor delivery, if any at all, or failing a commercial scenario. However, these assets gain more and more adherence, but an attractive commercial solution is sought, nevertheless catering for the specific needs and challenges arising from the fields in question.

Mature (or brown) fields often suffer from low wellhead pressures, making them unable to flow to the required first stage separation plant. Moreover, as intermediate gathering stations may have been closed in and dismantled due to an overall decreased production, even longer flowlines will lead to a higher pressure demand. Increased water content renders additional challenges because of higher pressure losses. In addition manpower in the fields has been reduced, giving a high rank on availability for new equipment to be installed. Furthermore regional legal frameworks call for stringent environmentally friendly handling of hydrocarbons. Thus, where gas flaring was state-of-the art in the past it is no longer allowed today. Subsequently the past common production scenarios require adjustments to a considerable extent.

Multiphase pumps are particularly suited, to help overcoming the above-mentioned issues. Their ability to add energy to the untreated wellstream, while reducing the wellhead pressure creates an entirely different pressure regime in the production system. While downhole inflow performance is enhanced, differential pressure across downhole pumps is decreased and at the very system end the gas delivery pressure is increased.
