... Abstract In recent years, the Oil and Gas Industry has greatly improved efforts in evaluating the electrical system involved in operating Electrical Submersible Pumps (ESP). The negative effects that poor power quality has on ESP motors equipped with variable speed drives is generally...

... 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...

.... This test data is used to validate the analysis approach used as well as to finalize the integration size of the PMB to meet the performance requirements of the MDS system. To identify rotor operating speed and rotor vibration magnitude and frequencies, the MVS is tested for sensing rotor motion rate...

.... The MLP was commissioned and started up in November of 2018. The initial weeks of operation were marked by frequent trips caused mainly by a non-optimized controller combined with excessive flow transients generated in the flowlines and risers, and lack of understanding of the interaction between the pump...

... contradictory results. The Field Operational Score (FOS) was developed as a more holistic and integrated approach in measuring ESP performance answering questions such as how often do downtime event occur and how long do they last? How fast can we identify a trip and restart production? How many days...

... in the design and operation of ESP in the petroleum and water sector, reliability of geothermal ESPs requires further improvement. Frequent failures have been observed that resulted from sub-optimum design, installation and operation of these systems which made the lifetime of them shorter than the expected 5-7...

... Abstract The paper reports on the integrated modeling approach for the Gulf of Mexico ultra-Deepwater Perdido Electrical Submersible Pump (ESP) meant for performance surveillance and operational predictions n viscous fluid and multiphase flow regimes. The ESP system uses in Perdido field...

... was operated normally at 55 Hz for a few months. An 8-hour shut down test established an initial base line cooling rate of 6.6°C/hour. Subsequent 6-hour deadhead tests at 30Hz and 45 Hz showed decreased cooling rates of 4.0°C/hour and 2.2°C/hour, respectively. This result clearly established the potential...

... with components that had multiple qualification and validation testing requirements. The motor and associated high voltage connector were key differences from the existing systems. The pump design was modified to accommodate projected operating ranges including additional stages for the necessary head...

... volume of fluid supply and tend to overheat in high-temperature conditions. To compensate for the heat, induction motors must operate underloaded. Even so, they are subject to frequent premature failures with operating times of between 30 and 100 days. To solve the problem of cost-effective exploitation...

... Abstract NCG (Non-Condensable Gas) co-injection with steam has been in operation at Surmont SAGD field since 2017. After a significant number of operational attempts to mitigate ESP no flow events (deadheading) suspected to be instigated by increased production of gas (typical SAGD GOR 5-10 m3...

... Abstract The paper reports on the integrated approach for the Brazil Deepwater BC-10 Electrical Submersible Pump (ESP) Operation without Downhole ESP gauges to safety operate the system and surveillance on light to heavy viscosity fluids and two phases, liquid – gas flow. The Electrical...

..., nodal analysis, chemical treatment monitoring and real time surveillance of the ESP parameters. Dashboards of water handling, electrical power, and chemical treatment are utilized to support process analysis providing current field status, with also the feedback from operational and engineering...

... Abstract One of the major challenges in SAGD Electrical Submersible Pump (ESP) operation is produced water flashing to steam when flowing pressure loss is significant, such as at an ESP intake. "Bottom Feeder" style intakes are a standard SAGD ESP intake which has been applied in the SAGD...

... Abstract An operator planned to install ESPs to overcome high water cut and minimize the gas supply risk for a gas lift completion at a platform in the Gulf of Mexico. The platform is an oil collection point and its continuous operation is essential during any rig-assisted interventions...

..., which also contains the main control room. Champion B2/B3 Project ESPs in Champion With increasing competency, eight offshore operations staff are now at a basic knowledge level with another three onshore operations staff. Additionally, one local production technologist has now been...

... Abstract A new high-temperature electric submersible pump (ESP) system was introduced in 2017 that is designed to address documented failure mechanisms and improve system reliability for steam-assisted gravity drainage (SAGD) operations at 250°C. A closed-loop product improvement workflow based...

... the number of start-ups and shutdown cycles, the main cause of seal failures in applications such as SAGD is solid fines affecting the operation of the top mechanical shaft seal. Implementing remedies to eliminate consequential motor damage from full or partial failure of the top seal was required. Thus...

... to be an enhancer rather than an enabler by extending the production plateau 5 to 8 years after initial well/field startup with natural flow and seabed boosting. Hence, a robust ESP system that can be installed and operated a few years after field startup without a workover for replacing the upper completions...

... wireline (slickline) or electric line, both readily available locally, providing installation operation flexibility. Vendor 2's system requires electric line or CT, which due to space limitations, will result in an increased complication as a deployment method. Vendor-1 system is shorter and lighter...
