It designed for fitting bottomhole assembly for the purpose of its direction along the wellbore and protection from damage during well construction of difficult wells.
It is equipped with eccentric plastic guide plug, which rotates during casing running. Rotating in the direction of least resistance the guide plug orients the shoe during running operations allowing bypassing obstacles facilitating casing RIH in difficult wellbore sections, sharp bends and curvatures.
Eccentric plug has three circulation holes directed apart fro provision qualitative flushing. Body of the shoe has three additional side circulation holes.
For the cases when during casing RIH the priority is circulation through central holes only there is shoe modification where side circulation holes closed by bursting discs. In case of central holes plugging the side holes are opened. This happens by means of creation over pressure in casing. When specific pressure value is reached discs are destroyed and circulation goes through created holes. Easy drilling polymer materials are used in producing shoes. This allows drillingout using PDC bit without any damages to the bit.
