Abstract
A dried latex emulsion coating on a surface of a metal member is used as a thin bond layer on well tubular joints, on tubular strings in wells, and on other metal members. The bond layer promotes adhesion to cement members formed from hardening a cement slurry in contact with the bond layer. The bond layer can be used in bonded cement structures, on well tubular joints, on tubular strings in a well, on tubular strings cemented in a well, in methods of making the cement structures and the tubular strings, and in methods of placing and cementing a tubular string in a well.
