The casing string in the hole drilling, used to prevent the formation of formation fluid flow and collapse.
The tubing string into the production casing, components of underground reservoir and the ground channel, control of crude oil and natural gas flow.
Casing is a wide range pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore
It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing, to allow drilling fluid to circulate, and extraction to take place
Steel casing pipes have smooth wall and minimum yield strength of 35,000psi
Tubing: tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete
It is made to withstand the pressure generated from the extraction process
Tubing is manufactured in the same way as casing, except that an additional process known as "upsetting" is applied to thicken the pipes
Process: ERW and seamless
Standard: API 5CT
Certificate: casing: LTC, STC, BTC, VAM
Tubing: NUE, EUE
