... through the cement ( e.g. cracks or global changes in cement permeability), or leave a micro-annulus when recovery has been completed and thermal operations halt. This paper describes the impact of key thermal and mechanical properties on the structural performance of cement blends in thermally...

... to satisfy these goals and priorities, working together to understand the challenges becomes critical. A clear understanding of the challenges provides an opportunity for the service company to tailor cement blend performance with the goal of eliminating the presence of SCVFs and reducing the costs...

... in bottom hole static temperature (BHST) and BHCT require complete understanding of the cement blend performance and its specific application. Cement blend designs that are applicable and can perform over a range of temperatures reduce the impact of these challenges. With the frequency of Infill cementing...
