Unexpected ESP failures lead to weeks or months of suspended production

The average electric submersible pump (ESP) runs to failure in just 2-3 years, due to harsh operating conditions. Failure is often unexpected, making it difficult to replace the ESP in a short time frame. What’s more, efforts to prolong ESP run-life often center around data from downhole sensors, which can fail themselves due to the harsh conditions down the well.

Problem 1

Lost production

Non-productive time can stretch from 16 days to 7 months.

Problem 2

No visibility

Downhole sensors frequently stop working before the ESP itself.

As bombas eléctricas submersíveis falham principalmente devido a falhas eléctricas

O gráfico abaixo dá uma ideia da divisão percentual dos modos de avaria das bombas eléctricas submersíveis com base nos resultados médios de uma análise estatística de 971 avarias de ESP ao longo de 5 anos em 10 poços (fonte 1, fonte 2).

A maior parte de todas as falhas dos ESP é causada por falhas eléctricas

... é aqui que o Samotics se destaca

A tecnologia de Análise de Assinatura Elétrica do Samotics está na melhor posição para detetar falhas elétricas. Os nossos sensores continuam a funcionar depois de um sensor de fundo de poço se avariar, porque instalamos os sensores em segurança dentro do armário de controlo do motor de superfície.

Decrease suspended production time through advanced warnings and run-life extending insights

What if you could see ESP failure coming days to weeks in advance? That would allow mobilizing a workover rig, getting replacement parts and scheduling a crew even before failure happens. For typical oil field operations, this saves days to weeks of suspended production.

Ao mesmo tempo, dispor de uma fonte fiável de informações operacionais sobre o ESP permite aos operadores ajustar as suas definições de funcionamento para prolongar a vida útil do ESP.

Samotics covers the most common and costly ESP failure modes

Detect the most common electrical faults - both in surface equipment and the downhole motor

Current/voltage unbalance
Current/voltage harmonic distortion
Overcurrent and voltage peaks
Broken/loose rotor bars
Stator winding failures
Problemas de qualidade de energia

Solve above-ground electrical issues to extent ESP lifetime or be warned for imminent motor failure, enabling timely overhaul preparations.

Example: Sine-wave filter failure

SAM4 detected a severe increase and imbalance in the main harmonics, indicating electrical component failure—likely in the sine wave filter.

The customer investigated and was able to repair the sine wave filter in time, preventing a ‘dirty’ power supply to the ESP and reducing the risk of early failure.

Identify anomalies and mechanical wear before it leads to ESP failure in the full application: motor, coupling and pump stages

Accurately predict upcoming ESP failure. Enabling operators to prepare for an overhaul, reducing lost production time.

Example: Mechanical rotor (blade) degradation

SAM4 detected increased energy around the 2nd and 4th harmonics, indicating mechanical wear on one of the rotors within the ESP. The customer was able to prepare for ESP replacement, reducing turnaround time.

Gas locking, dry-running, or other changes in intake conditions are detected accurately and in real time - 24/7 - by identifying patterns such as:

Enabling operators to take action, increasing production and extending the ESPs lifetime.

Example: Real-time gas-locking detection

SAM4 identified gas-locking through a combination of excessive cycling combined with spikes and inconsistent power consumption, indicating unexpected changes in the process or pumped medium.
