PSL1 PSL2 PSL3 Production Class Seamless Casing Pipe
Casing pipe description:
API 5CT casing 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.
The cost of casing is a major part of the overall well cost, so selection of casing size, grade, connectors,
and setting depth is a primary engineering and economic consideration.
