Paper: Fluid Caliper A Useful Tool To Improve Primary Cementing

Primary cementing is simple, i.e., displace drilling mud with cement to form a hydraulic seal between the pipe and the borehole. All too often, efficient drilling mud removal is not achieved, the cement cannot form a hydraulic seal and the result is communication between zones. This paper provides a discussion on the use of a fluid caliper to improve the success rate of primary cementing. The fluid caliper is an extension of mud conditioning and, used in conjunction with centralizers and other proper cementing procedures, provides for a surer primary cement job. Procedures and case histories are included.
