BKK-R1 Composite column shoe

BKK-R1 Composite column shoe are designed for equipping the bottom of casing strings consisting of pipes in accordance with GOST 632-80, GOST 633-80, as well as strings consisting of smooth insert joint casings in order to direct them along the wellbore and protect them from damage during descent while fastening the oil and gas wells at the face temperature of +160 °C.

Composite float shoes are sturdier and more reliable in comparison to cement shoes, while they are drilled out just as easy.
