DeepStar selects Upwing Energy and Mitsubishi Heavy Industries for ESP topology study

ESP studyUpwing Energy, an artificial lift technology company, and Mitsubishi Heavy Industries (MHI) have been selected by DeepStar to perform a feasibility and conceptual study of Upwing’s magnetic drive system (MDS) for electric submersible pumps (ESPs)

The study, targeting deepwater offshore and subsea well applications, is sponsored and funded by the Nippon Foundation - DeepStar Joint Ocean Innovation programme and supported by project champions Chevron, Shell, Petrobras and Equinor.

The study will assess the feasibility of MDS, a new, innovative topology for downhole rotating systems, which makes artificial lift devices, such as ESPs, more reliable, retrievable and efficient. MHI will design and analyse the pump and mechanical bearings for the system.

The Upwing and MHI engineers will begin work on the project in early June and are scheduled to complete the study by March 2020.

The project’s scope of work includes the three main subassemblies of the complete MDS pump system, which includes the deployment and intervention mechanism, magnetic drive system and pump and bearing systems. Based on preliminary indicators, the MDS pump system will significantly improve the reliability and retrievability of ESPs, while decreasing the total cost of ownership by 75 per cent in deepwater offshore applications.

Herman Artinian, president and CEO of Upwing Energy, said, “This study will significantly advance the technology readiness level of MDS and will make ESPs the economically preferred method of artificial lift for deepwater production, which will significantly improve the field recovery factor.”

“The ability to improve the existing ESP topology has reached its limit, and further improvements at the component level do not provide a huge gain at the system level in reliability or performance,” said K-C Chen, vice-president of engineering at Upwing Energy.

DeepStar is a joint industry technology development programme focused on advancing technologies to meet its members’ deepwater business needs to deliver increased production and reserves. DeepStar members include Shell, Total, CNOOC, Anadarko, Equinor, ExxonMobil, JX Nippon, Chevron, Petrobras and Woodside.
