... Abstract In permanent magnet motor electrical submersible pump (PMM-ESP) applications, the motor can act as a powerful electric generator when well fluids from either an upward or downward flow initiate the pump to rotate and subsequently creates motor rotation. This uncontrolled voltage source...

... Abstract With the increased use of permanent magnet motors (PMM) versus less efficient induction motors (IM) comes an increased safety risk. While both the IM and PMM can generate power themselves if their shaft is turned by external forces, the induction motor cannot generate enough power...

... Abstract With the emergence of permanent magnet motors (PMM) in the ESP industry, new challenges have arisen regarding the potential for electrical energy generation during installation, operation, and pulling of the equipment. Among these challenges include how to properly terminate the ESP...

... Abstract Electric submersible pumps (ESPs) using permanent magnet motors (PMMs) play a key role in lowering the cost of operations and reducing carbon footprint by reducing power consumption by 15 to 20%. As the use of PMMs becomes more prevalent, concerns about PMM safety are rising...

... the development and qualification of a new ultrahigh-power-density permanent magnet motor (UHPD PMM) for wireline-retrievable ESP systems installed through tubing as small as 5.5 in. The UHPD PMM design can produce significantly greater output than any other ESP technology in a single-section motor short enough...

... Abstract A Permanent Magnet Motor (PMM) designed to break the 300°C barrier was previously presented that included many advancements to greatly improve the operating temperature and reliability beyond the ability of current equipment [ 1 ]. A key design element is the inclusion of a squirrel...

... Abstract Permanent magnet motors (PMMs) have been used in electrical submersible pump (ESP) applications worldwide, but the oil and gas industry still has questions about the value of the technology in terms of power savings; return on investment (ROI); and evaluation of power consumption...

... This risk of electrocution means careful attention is required during deployment and operation to ensure safety. The PMM can be deployed in similar a fashion to an IM, but because of the weight difference, other deployment methods can be used for PMMs. ESP deployments in use today are shown...

... Abstract The induction motor has dominated the global ESP market for decades; however permanent magnet motors (PMM) are gaining acceptance for use in artificial lift. Some PMM vendors have made claims of 20% - 30% reduction in electric operating costs, improved efficiency, and wider...

... technology due to its high gas/oil ratio and unusual production profile. Multiple conventional ESP installations, set above the perforations, using induction motors (IM) failed shortly after installation and were unable to maintain continuous production. A permanent magnet motor (PMM) ESP system...
