The present invention provides a cement shoe assembly for use on a string
of tubulars in a well. In one aspect of the invention, the cement shoe
assembly includes a housing having a lower portion with an enlarged
inside diameter and a drillable cement shoe disposed therein. The shoe
includes a weakened portion of material adjacent the enlarged inside
diameter portion of the housing and ensures that as a cutting tool passes
through the housing, all portions of the cement shoe are removed from the
enlarged inside diameter portion, leaving a connection surface clear of
debris for a subsequent tubular string. When a smaller tubular is
expanded into the enclosed diameter portion of the housing, a connection
is made therebetween without enlarging the outer diameter of the housing.
