Multiphase Pumping Technology

January 7, 2014

Multiphase pump technology allows increased development of remote location, deepwater plays and for fields deemed uneconomical due to low flow pressure. With the ability to handle high gas volumes as well as potentially reducing the risk on the environment, multiphase pumps are being increasingly used for subsea and downhole applications. Selection of multiphase boosting options remains a bit subjective and is frequently influenced by the seller’s informationwhich may mask potential limitations of this emerging technology. Information on multiphase pumping tends to focus on a certain pump type for a specific field application, but does not provide more-generalized criteria for the selection of multiphase boosting solutions from among those available in the market.

Subsea Processing Systems Expanding in Brazil

The advent of reliable subsea processing has taken a considerable time to develop. For a few years now, it has been looked at as a vital solution for deepwater O&G development. Subsea processing technology was first developed to overcome challenges posed by extremely deep wells but in time it has become a proven solution in mature fields by decreasing the amount of equipment on the surface, therefore lowering operational costs and of course by boost diminishing production from mature wells, normally through re-injection of fluids, such as water, into the wells to increase the pressure inside the well. It is also an important solution in locations where harsh surface weather conditions make it extremely risky to have an anchored production plant.

Phase IX is the current phase of the project. The DeepStar project  is a joint industry technology development project focused on advancing the technologies to meet its members' deepwater business needs to deliver increased production and reserves. Phase IX is the current phase of the project. DeepStar Phase IX commenced in January 2008 with nine Oil Company Participants. DeepStar participants represent a strong mix of large and mid-size operators, USA and non-USA based, drawing in a rich array of diverse expertise to address common deepwater challenges.

Baker Hughes Subsea Systems in Brazil

March 9, 2010

Baker Hughes Centrilift ESP system pumps can be found in various important Petrobras plays. Petrobras has been using the Baker Hughes Centrilift subsea pressure boosting system in the deepwater Jubarte Field offshore Brazil in the Campos Basin for about three years now. The one megawatt electrical submersible pumping system (ESP) was installed at Jubarte in November 2005, but was not brought on line until 2007, following hook up of the Floating Production Storage and Offloading (FPSO) vessel. The system is producing approximately 22,000 BPD in 4,600 feet of water. Petrobras installed at least eight additional vertical booster stations using ESP technology at Jubarte in the months following the first system going online..

Improving Production Using Subsea Separation Boosting

Subsea gas-liquid separation coupled with liquid boosting can be an effective means of oil reservoir exploitation. Despite advances, multiphase pumping technology remains limited in its capabilities. Dynamic (centrifugal and helico-axial) pumps function with reasonable efficiency for single-phase, low-viscosity liquids. However, they become very inefficient when a high-viscosity liquid is combined with high percentages of free gas. While use of multiphase pumps is in many instances an effective solution, special consideration must be taken when challenging conditions exist such as are found in deeper water or with long tieback distances, or when heavy-oil production is involved. More effective oil reservoir exploitation can be achieved using subsea separation coupled with liquid boosting.

With major subsea contracts signed with Petrobras in 2009, the future looks bright for Aker Solutions and their range of subsea products and solutions in Brazil.In November 2009, Aker Solutions do Brasil signed two contracts to supply subsea connection systems for the P-55 platform, which will operate at the Roncador field offshore Brazil. The contracts were signed with Petrobras and Subsea 7. For Petrobras the contract involves three Plets (pipeline-end termination systems), two rigid jumpers, tools and accessories. For Subsea 7 the contract involved two sets of 12" Plets, one set of 12" ILT (t-shaped pipeline), tools and accessories. The values for each contract were not disclosed.
