Casing is the major structural component of a well. Casing pipe lines the borehole. It is subject to axial tension by its dead weigh, internal pressure by fluid purging, and external pressure by surrounding rock formations. Casing is particularly exposed to axial tension and internal pressure by the pumped oil or gas emulsion. Casing is needed to: Maintain borehole stability
