61 WELL-SUN Cement Bond Logging Well cementing is a critical step in well construction. The cement sheath provides a hydraulic seal that establishes zonal isolation, preventing fluid communication between producing zones in the borehole and blocking the escape of fluids to the surface. The cement sheath also anchors and supports the casing string and protects the steel casing against corrosion by formation fluids. Failure to achieve these objectives may severely limit the well s ability to reach its full producing potential. WSTbus Logging is usually run either immediately after a cement job or just before perforation to evaluate cementing quality. The information provided by cement bond logging is crucial in planning a remedial job. It reduces risk, unnecessary expense and saves time and resources. Cement bond logging tools ranging from conventional CBL to modern RBT and SBT are all available on market by Well-sun.
