Electric Submersible Pump

ESPBend helps companies investigate the effects of wellbore curvature on ESP equipment deflection and reliability. ESPBend allows users to perform detailed engineering stress and curvature analysis of complex wellbore trajectories and ESP assemblies. 

Companies can then combine engineering analysis results with their own historical failure data to estimate the long-term economic implications of wellbore curvature in their ESP-lifted wells.

The need for a robust pumping system capable of operating in the challenging conditions presented in geothermal production wells has been identified as a critical piece of equipment for the advancement of geothermal energy utilization. In typical geothermal operations, establishing and maintaining a high production rate at high temperatures is critical to the economic viability of the project. Electrical Submersible Pumps (ESPs) have significant advantages over other commonly used pumping...

The Industry Challenge

Due to the costs associated with implementing an Electric Submersible Pump (ESP) system most operators are very focused on maximizing reliability.  Historically, however, the Seal component has not mandated the same level of technical investigation as other downhole components. 

ESP Seal design is still perceived by many as an empirical process.  It is not clear how key design parameters, such as bag expansion/contraction volumes, relief valve opening pressure, and flow...

The Industry Challenge

Several Steam Assisted Gravity Drainage (SAGD) operators have observed flow instabilities in their Electrical Submersible Pump (ESP) produced wells, commonly resulting in the complete loss of fluid flow to surface. In some wells these instabilities appear without any apparent precursor signs or indications of a potential flow disturbance, while in other wells there are clear indications of gas entering the pump (e.g. evident by flow and current fluctuations).

In many cases...

It is well known that the presence of gas degrades the hydraulic performance of Electrical Submersible Pumps (ESPs). However, there are no accurate methods for estimating this degradation for multi-stage centrifugal pumps, which makes it challenging for operators to:

  • Select the proper pump model for the application
  • Size the selected system (number of stages, required motor horsepower, etc.)
  • Operate and optimize the installed ESP System (expected vs. measured performance)

The poor estimation of...

Course Overview:

This course will provide attendees with a basic understanding of Reliability Theory and Run-Life Measures, and an overview on the Industry best practices on ESP failure nomenclature, data collection, and data analysis.

The objectives of this course are to:

  • Review the Failure Nomenclature Standards for collecting and tracking ESP failure information;
  • Learn how to apply the Failure Nomenclature Standards to common types of ESP failures;
  • Review Reliability Theory and common run...

This paper was prepared for presentation at the SPE ESP Workshop held inHouston, Texas, USA, April 25-27, 2001.

Abstract

Several operators have recently launched a new industry-wide initiativefocused on sharing failure information, operational practices and otherpertinent data, in an effort to gain a better understanding of the variousfactors that affect ESP run life in any one application. Early on, thecompanies involved acknowledged that there were many challenges in such aneffort, one of the...

Abstract

ConocoPhillips has been on a quest for a high-volume artificial lift system that will operate reliably in a 250°C (482°F) downhole environment. This paper will describe the testing and results of a high-temperature electric submersible pump (ESP) system in a flow loop built to validate downhole equipment for thermal applications, primarily for steam assisted gravity drainage (SAGD) developments. What makes this test program unique from previous tests is the longer duration (4+ weeks),...
