The producing performance of a well depends in great part on a good primary cementing job. In a high-quality cement job, all mud and gas channels have been permanently prevented and there is a complete hydraulic seal between the casing and the formation throughout the zones of interest. If the cementing operation is not carried out correctly, the well will never reach optimum performance. A successful primary cementing operation requires a positive attitude and commitment, proper supervision and quality control, detailed planning, and careful preparation. This paper discusses the application and interaction of these aspects of the job, as well as other factors that contribute to successful cementing. Examples of unique quality control procedures are included. The actual mechanics of performing a cementing job are not covered; they can be obtained from references included in the paper.
