Casing is a crucial component in the construction of oil wells. It plays a vital role in ensuring the integrity and stability of the wellbore, protecting it from external forces and preventing any potential leaks or collapses. Casing is essentially a large–diameter Pipe that is inserted into the wellbore and cemented in place. It provides structural support to the well and acts as a conduit for the extraction of Oil and gas.

One of the primary functions of casing is to prevent the collapse of the wellbore. As the drilling process progresses, the wellbore encounters various formations with differentlevels of pressure and stability. Without proper support, these formations can cave in, leading to a loss of drilling fluid, equipment, and potentially even human lives. Casing, with its robust construction and high–strengthmaterials, helps maintain the integrity of the wellbore, ensuring that it remains stable and secure.

In oil drilling, it is common to encounter different layers of rock formations, some of which may contain water or other fluids. Casing prevents the migration of these fluids into the wellbore, which could contaminate the oil reservoir or interfere with the drilling process. Additionally, casing acts as a barrier against the intrusion of external contaminants, such as saltwater or gases, which could damage the well or affect the quality of the extracted oil.
