High-quality zonal isolation remains one of the most important and complex challenges of the modern oil and gas industry. A systematic approach is required to ensure high-quality casing cementing. Selection of the optimal cement slurry formula should be based on the accumulated statistics obtained in the course of similar cementing operations: cement slurry/stone parameters (density, flow ability, water trapping, compressive/flexural strength, thickening time, setting strength) should meet the required values in the design and estimate documentation (DED) and the technical specifications (TS). However, measuring the above parameters alone is not sufficient for high-quality cementing. The authors of the article consider a comprehensive approach to selecting a cement slurry design for casing strings cementing based on the specific geological and technical conditions of the well, the actual availability of specialized cementing equipment at the well pad, and the type of wellhead equipment (in case of two-stage cementing, a liner, etc.). A modern classification of cement additives is provided.
