Coiled TUBING is made of low-carbon alloy steel. It has good flexibility, also known as coiled Tubing. A coil of coiled tubing is thousands of meters long. It can replace conventional tubing for many operations. The coiled tubing operation equipment has the characteristics of operating under pressure and continuous tripping. The equipment is small in size, fast in operation cycle and low in cost.
During World War II, 17 special metal pipelines solved the Allied military oil transportation problem across the sea. In the early 1960s, this technology was applied to oil workover operations, which started the oil career of coiled tubing. Fifty years later, coiled tubing operations have become a hot spot in the oil and gas industry

Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells or wellbore.

It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow

drilling fluid to circulate and extraction to take place
