A method and apparatus for locating and determining the quality of a downhole wet cement abandonment plug positioned in an open bore hole. The quality of the plug is determined by retrieving a sample of the wet cement mixture to the surface by remotely operating a fluid sampler included as one component in a logging tool. The sample permits the determination of the purity and quality of a downhole wet cement plug, providing valuable information for assessing whether the plug will set properly. Thus the method and apparatus greatly reduces the risk of plug failure due to an inferior cement mixture resulting from the intrusion of contaminants in a wet cement plug. PAT 1020-1 |
