A centralizer – just another component we might consider insignificant when planning a well, but make no mistake, thanks to the proper centralization of the casing in a well, we achieve higher rates of production, increase life-time of a well and reduce the risk of unexpected accident on a rig

Shoes and couplings are usually used in the lower interval of the well and provide a reduction in the load on the mast when running the casing through zones with ledges and collapses in the wellbore, as well as landing sites for the lower and upper cementing plug. The back pressure valve prevents fluid from flowing into the casing when the pipe is lowered into the well and prevents cement entry back into the casing after injection, while allowing circulation through the casing.
