Abstract:
The invention provides a method of determining the condition of a cement bond of a casing in a wellbore. The method comprises perforating a tubing in the wellbore at a zone of interest and displacing a settable composition through the perforations into the annulus between the casing and tubing to secure the tubing. The method also comprises cutting the tubing and assessing the status of the cement bond of the casing.

Claim (Index 9):
A method for abandoning a well, the well including a cemented section behind a casing in a wellbore and production tubing within said casing at said cemented section, the method comprising:\n (a) perforating the production tubing in the wellbore at one or more zones of interest at the cemented section; (b) passing a settable composition through the perforations into the annulus between the casing and the production tubing; (c) allowing the settable composition to set to secure the production tubing to the casing at said one or more zones of interest; (d) deploying a milling tool to mill away the production tubing and the settable composition over said one or more zones of interest to access the casing at the cemented section; (e) performing a cement bond log at said one or more zones of interest; (f) deploying a cement plug upon no leaks being detected at said one or more zone of interest.
