N350, N370
NORD float shoe is intended to guide casing safely to cementing depth and protecting casing during run in hole in the construction of oil and gas wells. Reinforces the lower end of the casing.
Allows for optimum performance in wells where extreme conditions are observed and/or expected such as ultra deep wells, high pressure and hight temperature wells.

Shoes
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.
