Abstract
The study aims to identify the particular problems of progressive cavity pumps (PCP) systems found in petrodara company fields in the last four years. The problems have been subjected to a standard systematic analysis, including the causes and effects that have been tested in during the period of the study, where it was to take advantage of the classification of these problems and solutions for them which lead to the development of an expert system program to be a guideline while dealing with progressive cavity pumps systems
