Progressive Cavity Pumps - Application Engineering
The Progressing Cavity Pumping System (PCP) is considered the faster growing artificial lift method in the last two decades. Its applications cover very low downhole pressure wells, solids handling and viscous oils. Actually the PCP companies have improved the reliability of the whole system including new elastomers development, better gas separation and optimization using surface controller. Because its minimum initial cost and operational flexibility, this is very suitable solution for heavy oil fields development.
This course will allow the attendant to acquire a solid knowledge of PCP and its applications. It covers detailed description and function of each component of PCP system. Basis of reservoir inflow performance, artificial lift systems comparison, standard and special applications, system components, design, diagnosis, troubleshooting and optimization are described and discussed. A set of practical examples and problems are solved in class. Analysis and Troubleshooting of PCP are treated in a dedicated section of the course.
Course Objectives: Provide theoretical and practical knowledge of the advantages and limitations of the Progressive Cavity with the purpose of develop the required skills to design, optimize and diagnose wells producing with this artificial lift method.
