Oil well intake structures are generally limited to two basic types. The first, and most commonly used, is a casing with milled slots. Not only is this type of product relatively inexpensive but also durable, easily installed, and efficiently developed. The limitation of this screen is its inability to retard the entrance of fine sands and silt into the well.
When formations preclude the use of mill-slotted pipe, wire-jacketed, pipe-based screen is used. This product is comprised of a continuous slot screen cylinder fitted over a pipe that has been drilled with holes. The advantages of this product are its strength and ability to limit the entrance of fine materials into the well. Unfortunately, it is often difficult to develop and rehabilitate. Should the screen jacket be damaged, the material adjacent to the screen quickly and easily enters the well.
An alternative pipe-based screen has been developed by Roscoe Moss Company. This product utilizes shutter screen as the internal structure. The benefits of this product over traditional pipe-based screen include; higher strength to weight ratio, wide selection of corrosion resistant materials, better formation control should the outer jacket be damaged, and lower cost.
