Executive Summary

Sand production in reservoir wells creates a number of problems, some of which are costly and others that might cause safety issues. Excessive sand production can lead to significant reduction of hydrocarbon production performance as well as damaging bottom-hole assemblies and production equipment. Furthermore it could lead to the well being shut-off for sand to be circulated. In this work, however, comprehensive review study has been carried out about the Sand Control and Management systems to explore available methods practiced in the petroleum industry to date. The fundamental theories and concepts have been reviewed and also presented systematically, which includes explaining the physical mechanism of sand production in wells, properties of the rock and its strength and influences on production performance.

The report will covers techniques that have been used in the industry which are broken down into four major groups:

(1) Mechanical Methods
(2) Production Restriction
(3) Chemical Injection and
(4) A combination of the above methods

Various tools and methods have been found to be dealing with sand production, but like all projects the economics is a major influence in selecting the appropriate sand control and management strategies and there is no one universal sand control method that can suit every situation.

General guide lines are provided based on this review work, which helps engineers to use best and appropriate techniques to overcome sand production problems for different scenario.
