Advantages and disadvantages of fiberglass casing in oil and gas wells
Casing is an extremely important element in the process of drilling a well borehole, as they define the diameter of the well and, among many other tasks, protect it from collapsing. In order to ensure long-term successful performance of all tasks, it is necessary to appropriately dimension casing, which means that the appropriate inner and outer diameter should be selected with the appropriate material and its quality, with proper installation depth for each set of casing. Conventional casing made of steel is most often used and this is still an ideal material for most wells. However, this material is prone to corrosion, which is a major problem on certain locations du ring the
production life of the well. Reduction and possibly elimination of corrosion on casing led the industry to explore financially viable composite materials, such as fiberglass, that could withstand expected stresses in well conditions with better corrosion resistance th an steel.
