Multiphase pump

The principle has been developed to add energy to a fluid mixture of water, oil, and gas (i.e., an unprocessed wellstream). The pump is arranged as a multistage unit. A pump that can handle the complete production from a well (oil, natural gas, water and san for example) without needing to separate or process the production stream near or at the wellhead.

This reduces the cost associated with the surface facilities. Using multiphase pumps allows development of remote locations or previously uneconomical.

Our product portfolio includes pumps and systems of all kinds, in nearly all sizes and capacity ranges. Multiphase Boosting Wherever a pump is neede we can deliver it. In addition to the pump design, a variable-speed drive (VSD) is commonly used to provide additional operating flexibility. FASTsubsea is a joint venture between Aker Solutions and Fsubsea to develop the world’s first topside-less subsea multiphase boosting system called FASTsubsea X. What is multiphase fluid flow?

By multiphase pumps a dispersion with very fine bubbles is being achieved. Therefore the multiphase pumps are also suitable as dynamic mixer. Some main applications are biofuel plants, dissolved air flotation, neutralization, water treatment, bio-reactors, crude oil water separation on oil rigs and on oil fields as well as general process technology.

The subsea multiphase pump system is an ideal candidate for satellite field developments, eliminating the need for remote process facilities in marginal fields that otherwise would not justify such investments. By introducing a subsea pump station, production may be boosted to the central processing facility. PCM provides cost effective and reliable pumping solutions to pump the multiphase mixture instead of having to install separation facilities at each wellhead cluster. While reducing capital cost, PCM technology lowers the backpressure on wells and improves the global footprint of the equipment.

The MPis a double suction, twin screw pump designed for continuous service in high viscosity applications where multiple phases are expected. With its unique double case design, it acts inherently as a separator to run multiphase products up to 1 gas void fractions at a wide range of flow rates, pressures, and viscosities. In cases where pump systems will see frequent or consistent gas volume fractions above a multiphase system should be considered. Because of this dynamic‚ multiphase systems are used primarily in Production settings and have also been used in Terminals and Refineries. Unpredicted events in a producing formation can result in gas pockets or gas breakthrough can start to develop.

In addition, the economics of multiphase production is attractive to upstream operations as it leads to simpler, smaller in-field installations, reduced equipment costs and improved production rates. In essence, the multiphase pump can accommodate all fluid stream properties with one piece of equipment, which has a smaller footprint. Unlike standard ESP pump sections, our multiphase pump stages have no left or right zones in which high concentrations of undissolved gas can collect and stop flow. So fluid and gas keep moving though the system. When gas volumes at the pump intake exceed , the head created by the multiphase pump begins to decrease.

Specifically designed for casing gas applications, the technology is a true multiphase pump as it can operate with both gas and liquids in fluid contents. Sophisticated algorithms allow the pump to operate autonomously. High-GOR, high-gas environments are now common electric submersible pump (ESP) applications, but to produce at full potential, main production pumps need the support of reliable gas handling technology.

The MGH multiphase gas-handling system is designed to manage this issue. The multiphase pump in a dual-booster installation handles the nominal liquid flows, but is usually oversized to manage fluctuating liquid rates. It works in conjunction with the flow divider.
