A quick definition of casing:
Definition: Casing is a pipe that is put into a hole in the ground to protect the environment and the well. There are different types of casing, including surface casing which is the first pipe put in the hole to protect the groundwater, intermediate casing which protects deep formations, and production casing which is the last pipe put in the hole and is used to produce oil and gas.
A more thorough explanation:
Definition: Casing refers to the pipe that is cemented into place in a wellbore hole to prevent pollution and protect the hole. There are different types of casing used in oil and gas drilling:
- Surface casing: This is the first pipe set in the hole and it protects groundwater from pollution caused by drilling and producing operations.
- Intermediate casing: This casing protects deep formations from pollution caused by drilling and producing operations.
- Production casing: This is the last pipe set in the hole and it is used to produce oil and gas from the wellbore.
For example, when drilling a well for oil and gas, the first pipe set in the hole is the surface casing. This casing is cemented into place to protect the groundwater from pollution. The intermediate casing is then set in place to protect deeper formations from pollution. Finally, the production casing is set in place to produce oil and gas from the wellbore.
