Multiphase pumping technology

IFPEN has considerable experience in the design of pumping systems and develops multiphase pumps. They make it possible to increase the pressure of unseparated liquid and gas production effluents for a broad spectrum of gas content levels, in order to transport them over long distances in flow lines. This technology makes it possible to:

  • increase the volumes produced and stabilize the production flow,
  • bring back on stream wells at the end of their life.

The Poseidon™ pump range enables the simultaneous transport of liquid and gas effluents, with a gas content ranging from 0 to 100% (preferably 80%).

Poseidon™ downhole pump 

More than 1,000 units sold.

Poseidon™ pump for submarine applications marketed by OneSubsea

More than 60 units installed.

The dimensioning and performance prediction of these pumps are carried out using design software developed in partnership with OneSubsea. With a view to optimizing pump performance, IFPEN is working to improve existing blades and define a new-generation hydraulic pumping system.

Flow assurance

In the field of flow assurance, IFPEN develops – or co-develops through R&I partnerships – models, test methodologies and solutions to:

  • understand and represent the physics of complex flows present in flow lines,
  • prevent or remove flow line blockages.

Research focuses primarily on:

  • understanding hydrate formation in flow lines, their transport, the risks of plugging and, where necessary, the appropriate methods of plug dissociation,
  • monitoring and modeling paraffin deposits in order to anticipate deposit growths,
  • paraffinic crude gelation and associated re-start problems.

Our service and expertise offer can take the form of studies or collaborative research projects. IFPEN organizes and coordinates JIPs (Joint industry projects), collaborative research projects bringing together industrial partners who jointly finance a program designed to understand and solve a target problem. With these projects, the financial risks are shared upstream and research results are shared downstream. They thus provide a platform for exploring avenues leading to innovations and give the partners a genuine competitive advantage with rapid access to new data, new analyses and new technologies. IFPEN is coordinating JIPs in partnership with more than 30 national and international operating companies.

Sensor dedicated to the early detection of a hydrate formation risk

Paraffin deposit monitoring and modeling system

The launch of a JIP in 2019 on paraffin deposits, with new deposit formation monitoring tools that will make it possible to:

  • gain a better understanding of deposit processes,
  • qualify deposit detection and monitoring methodologies.

Studies (additives and procedures) to prevent hydrate plugging in flow lines

In this area, the two phases of the AHToL (Additive and Hydrate at the Top of Line) JIP and the HYSIFLO (Hydrate Slurry Impact on the FLow properties of Oil fields) JIP involved working on the impact, control and optimization of additive injection, in gas and oil-dominant systems respectively, the objective being to provide operators with experimental proof and/or an extrapolation tool to help them choose their hydrate management strategy as a function of their field’s operating conditions.

« A JIP conducted by Technip FMC culminated in a global first. Tests took place between 2013 and 2015, with the formation and dissociation of hydrate plugs weighing 200 kg, on a heating pipe prototype built by TechnipFMC, connected to IFPEN’s testing facilities in Lyon. Different dissociation conditions were studied with a view to defining and validating operating procedures for the monitoring and safe dissociation of hydrate plugs by active heating. »

Offshore production remains strategically important for international oil and gas companies. According to current estimates, it is likely to represent 30% of total oil and gas production by 2030 and 50% of reserves yet to be discovered.

The sector’s players need to adapt to an oil market that is still very tense. They are seeking to reduce the costs of projects to make them viable, while developing increasingly safe, eco-efficient and effective exploration and production technologies.

In this context, IFPEN develops new solutions adapted to the prevailing conditions in the offshore drilling and production equipment market, as well as for flow assurance.

IFPEN forges partnerships with French and European oil industry and oil-related sector players, with a view to working with them to design and validate equipment and technological solutions for drilling and production, solutions they will subsequently market.

IFPEN’s core activity in the field of flow assurance is aimed at providing its partners with a comprehensive understanding of the physical phenomena occurring inside facilities. This understanding also enables the development of appropriate monitoring solutions, thereby limiting risks, ensuring safe operating conditions and optimizing production.

IFPEN’s high tech contribution addresses the most advanced needs of its industrial partners, in order to support their competitiveness in a field in which the technical and economic challenges are numerous.

The challenges of offshore production:

  • drilling and producing in ultra-deep water,
  • extracting fluids in sometimes high-pressure, high-temperature and corrosive conditions,
  • transporting fluids over long distances in a low-temperature environment without forming hydrate or paraffin plugs,
  • pumping a mixture of water, oil and gas with highly variable gas contents,
  • separating effluents (gas, oil and water) on the seabed.

The oil industry needs to have access to technologies enabling safe, cost-effective offshore drilling and production operations, against a backdrop of volatile, potentially low barrel price.

75% of new oil and gas volumes discovered in 2017 were located offshore.


Designing and validating equipment and technological solutions designed to provide access to offshore resources, while ensuring the delivery of safe, cost-effective drilling and production operations.
