Referring to FIG. 1, a tubular string 2 (e.g., a drill string, production tubing string, casing or liner) is shown after it has been cemented into a suitably drilled wellbore 4. Cement 6 is placed in known manner (e.g., by pumping) in the annulus defined between the outer surface of the tubular string 2 and the surface of the cut wellbore 4.
Also represented in FIG. 1 is a thin layer 8 between the tubular string 2 and the inner surface of the column of cement 6. This does not necessarily extend along the entire length of the tubular string 2 or column of cement 6, but it is shown in FIG. 1 to illustrate what is referred to as a micro-annulus made of, typically, a coating of the drilling mud or other fluid previously in the well before displacement by the cement 6.
If the layer 8 is not suitably removed and the surf...
