Upon the successful completion of this course, each participant will be able to:-

• Apply and gain an in-depth knowledge on the inflow & outflow performance and the system analysis in subsurface production operations
• Apply the latest methodology on artificial lift selection to lower the producing bottom hole pressure (BHP) on the formation to obtain higher production from the well
• Describe artificial lift selection and the operation of gas lift installation
• Define what is an electrical submersible pump (ESP) and have an understanding of ESP system components and accessories, operation, ESP system selection and performance calculations, installation and handling and maintenance and trouble shooting
• Explain hydraulic pumping in oil wells including its operation, accessories & surface equipment’s
• Possess the skills needed to select and design an artificial lift system, plan its operation, monitor, analyze and optimize its performance.
• Be able to manage and control the production of artificial lift wells and fields
• Be able to study and compare the cost between artificial lift systems.
• Real Time data gathering and interpretation.

The first objective of this course is to introduce the concept of NODAL analysis as a tool in production optimization and hence enhancement. Each learner will be exposed to the analysis of various components of the producing system and their effect on the performance of the total production system.

• Every oil and gas well requires a lift mechanism at some time-point. Often times during a well’s life cycle, changing conditions, necessitate switching from one to another lift method. Each lift system’s applicability often overlaps with other lift systems and it is important to understand when to use one and why not to use another. This course while providing instructions at awareness level will arm attendees with sufficient details to participate in informative decision making process.
