Methods and apparatus for wellbore construction and completion

A method of cementing a borehole, comprising:

• extending a drill string into the earth to form the borehole, the drill string including an earth removal member having at least one fluid passage therethrough, the earth removal member operatively connected to a lower end of the drill string;
• drilling the borehole to a desired location using a drilling mud passing through the at least one fluid passage;
• providing at least one secondary fluid passage between an interior of the drill string and the borehole;
• providing a sleeve positioned over an element of the drill string and intermediate the at least one secondary passage and the annulus and at least one shear element interconnecting the sleeve to the element of the drill string;
• moving the sleeve to allow a physically alterable bonding material to flow through the at least one secondary passage;
• and
• directing the physically alterable bonding material into an annulus between the drill string and the borehole.
