Abstract

CEMENTING APPARATUS

ABSTRACT OF THE DISCLOSURE
Apparatus is disclosed for use in placing cement within the annulus between a casing string and a well bore in which the casing string is suspended, such apparatus including a stage collar connectible as part of the casing string and having a packing element mounted thereon and adapted to be inflated into engagement with the well bore, one or more side ports through which cement may be circulated into the annulus above the packer, tubular members or sleeves for opening and closing the ports following inflation of the packing element.
