Artificial lift is a vital part of the life of many oil wells worldwide. Using several artificial lift methods can prolong the life of the wells and increase oil recovery significantly. One of the most applied artificial lift methods nowadays is the electrical submersible pump (ESP). This artificial lift method has the ability to handle large volumes of hydrocarbons and is applicable under many conditions in both offshore and onshore reservoirs. Even though ESP has been applied extensively for many years, it still suffers from many failures due to electrical, mechanical, and operational problems associated with the ESP downhole assembly. Understanding the main reasons behind ESP failures and how to rapidly and effectively avoid and mitigate these failures is imperative to reduce cost and damage and improve operational and rig-personal safety. This research performs a comprehensive review on ESP failure mechanisms and analyzes these failures in order to determine the optimum conditions to operate the ESP. This can help minimize and avoid these failures. Also, should these failures occur, the research proposes several mitigation methods for each failure based on analysis of different field cases worldwide.

Summary Electrical submersible pumps (ESPs) are a key artificial-lift technology in the petroleum industry. Worldwide, installed ESPs in oil wells are in the range of 130,000 units, contributing to approximately 60% of the total oil production in the world. An ESP is made up of hundreds of components integrated to perform the lifting function. Materials in these components belong to several categories, including metals, ceramics, polymers, and others. A good understanding of these materials and vigilant selection for a specific application are critical to the reliability and run life of an ESP system. This series of papers provides an overview of all major classes of materials used in ESP systems. It is intended to serve as a reference for ESP field-application engineers who are responsible for the design, equipment longevity, and production optimization. This paper focuses on polymers and other materials. The information compiled in this paper is the result of an extensive literature review. We cover materials used in the motor, protector, pump, and cable (sensor, packer, Y-tool, diverter valve, surface components of variable-speed drives, and transformer are not included). For each class of materials, we identify relevant material properties and discuss suitable application conditions.

It has been about 10 years since High Temperature Electrical Submersible Pumps (HT ESPs) were first deployed at downhole temperatures of 250°C (482°F). Since then, these pumps have become one of the most popular forms of artificial lift for most Steam Assisted Gravity Drainage (SAGD) producers. Despite this popularity, the severity of the operating conditions in SAGD wells continues to present challenges to the development of new HT ESP technology. A Joint Industry Project (JIP) of major thermal operators commissioned this research to evaluate the performance of some novel HT ESP technology that was developed by Summit ESP a Halliburton Company. This novel HT ESP technology was specifically designed to operate in a SAGD environment. This paper describes the full-scale testing that was independently conducted by the JIP on this HT ESP technology using a specialized high temperature flow loop at C-FER. Testing was completed to better understand the performance and reliability of this novel HT ESP technology over a wide range of representative SAGD conditions. The program included several diverse tests conducted at fluid temperatures up to 250°C (482°F). This included a wide range of operating conditions, including low levels of sub cool and different multiphase fluid combinations with oil, water, gas, and steam. As noted in past experimental work conducted on HT ESPs by Waldner et al. (2012), understanding the thermal profile of the ESP system (specifically the motor) as well as the effect of multiphase flow conditions on motor heat dissipation and pump hydraulic performance when operating in a SAGD wellbore are key considerations when assessing ESP systems. For this reason, additional downhole instruments were installed to monitor the temperature profile of the ESP system in the wellbore during this test. The experimental setup also included internal pressure monitoring of the ESP motor oil volume compensation system to carefully observe the interactions between the wellbore environment and ESP system performance. This paper presents an overview of the test objectives, the experimental setup (including the instrumentation), the HT ESP system, as well as a selection of key laboratory test results. Collectively this paper provides insight into the test methodology and performance of this new HT ESP under various conditions representative of a SAGD wellbore in the field.
