Sucker Rod Pumps - Application Engineering
The Sucker Rod Pumping System (SRP) is considered the most popular artificial lift method worldwide. Its applications cover very low downhole pressure wells, slim holes, multiple completions, high temperature and viscous oil. The SRP companies have improved the operation of the whole system including pump-off controllers, better gas separation, gas and solids handling pumps and optimization using surface and bottom-hole cards. Because its wide operation range and adaptability of the system to others wells with minimum cost becomes a economically attractive solution for oilfield development.
This course will allow the attendant to acquire a solid knowledge of SRP and its applications. It covers detailed description and function of each component of SRP. Basis of reservoir inflow performance, artificial lift systems comparison, standard and special application, system components, design, diagnosis, troubleshooting and optimization are described and discussed. A set of practical examples and problems are solved in class. Analysis of SRP is treated in a dedicated section of the course.
Course Objectives: Provide theoretical and practical knowledge of the advantages and limitations of the Sucker Rod Pumps with the purpose of develop the required skills to design, optimize and diagnose wells producing with this artificial lift method.
