COURSE DESCRIPTIONESP is one of the predominant forms of artificial lift used for lifting prolific quantities of liquids from conventional, unconventional, onshore, and offshore assets. Proper application of ESP is a must in any environment to improve the profitability of an oil-producing asset. ESP in its various configurations allows the life of well lift-possibilities when selected and applied correctly. This course gives trainees a thorough understanding of ESP artificial lift technology and related application concepts.

LEARNING OUTCOMES:

Most oil and gas wells require artificial lift at some point and for most of the life cycle to achieve production objectives. There are at least eight forms of artificial lift technologies available in the market. Each lift system’s applicability often overlaps with another lift system (s), and it is crucial to understand the positioning and strength of a particular lift form.

ESP is the most essential and often considered artificial lift around the globe for producing liquid quantities above 500 bbls/days from deep and shallow reservoirs. When properly selected and operated, it can deliver significant hydrocarbon volumes that can improve the initial rate of returns (IROR) of challenging to produce assets. That’s why it also commands the most significant capital expenditure allocations in global artificial lift markets on an annualized basis. On the other hand, poor selection and management can lead to suboptimal production rates with poor operational efficiencies and higher failures leading to differed production with higher CAPEX/OPEX.

It is vital to understand the interdependency between reservoir, wellbore, and surface installations with ESP equipment. This course focuses on ESP applications and related system analysis (often called NODAL analysis) concepts. While providing intermediate-level instructions, the training will arm attendees with sufficient details to participate in the informative decision-making process. The main objectives are as follows:

  • Provide a thorough introduction about the theory and application of ESP.
  • Demonstrate the advantages and limitations of ESP systems.
  • Acquaint the student with ESP system evaluation, design, installation, operation concepts.

The course covers the main components, application envelope, relative strengths, and weaknesses of ESP in its different forms. A unique feature of this course is a discussion on the digital oil field and machine learning as applied to ESP optimization.
