- Casing pipe is a large-diameter steel pipe used to line the wellbore during the drilling process and the production of oil and gas.
- Its primary function is to provide structural support and integrity to the wellbore, preventing collapse and maintaining the integrity of the formation.
- Casing pipe is typically installed from the surface down into the wellbore and is cemented in place to ensure a secure seal.
- It is designed to withstand high external pressures, protect the well from contamination, and facilitate the safe and efficient extraction of oil and gas.
- Drill pipe is a hollow, steel pipe that is used to create a borehole during the drilling process.
- It is comprised of various sections, called joints, which are connected together to form a string.
- Drill pipe is used to transmit drilling fluid and torque from the drilling rig to the drill bit at the bottom of the wellbore.
- Its main function is to provide the necessary strength, stiffness, and flexibility to effectively drill through various rock formations.
- Drill pipe is subject to high tensile and compressive forces and is rotated to create the borehole.
