Casing refers to the protective structure installed in a wellbore during drilling operations. It is typically made of steel or other durable materials and serves to stabilize the well, prevent contamination of groundwater, and isolate different underground formations. Casing is essential for maintaining the integrity of the well and ensuring safe extraction of resources like oil and gas.
The process of casing involves inserting long sections of pipe into the drilled hole and securing them in place with cement. This cementing process helps to seal the space between the casing and the surrounding rock, providing additional support and preventing fluid migration. Proper casing is crucial for the success of drilling projects and environmental protection.
