Sand Control Fundamentals
This skill module begins by discussing both the causes of sand production, and the effects that sand production can have on our oil and gas wells. The subsequent sections describe the methods and the equipment used to control sand production. All of the major types of sand control completions are discussed, along with their strengths, weaknesses and the conditions under which they can be applied. Many new technologies have been introduced is the last several years, such as FracPacking and Expandable Screens. This skill module will discuss several that have been successfully applied. We will also discuss many of the more common problems encountered, and how to avoid these problems.
