Cementing is the process of mixing a slurry of cement and water and pumping it down through casing to critical points in the annulus around the casing or in the open hole below the casing string. The two principal functions of the cementing process are to restrict fluid movement between the formations and to bond and support the casing. Cementing operations can be divided into two broad categories: primary cementing and remedial cementing. The objective of primary cementing is to provide zonal isolation.
Basic Cementing training presents the basic concepts of primary cementing and illustrates the adverse affects upon well performance of a poor quality primary cement job. Remediation using squeeze cementing techniques are discussed. The physical and chemical properties of cement slurries are reviewed. Cement evaluation techniques are discussed and finally a class project is performed in which the participants actually design a cement job and perform a cement evaluation.
A basic understanding of drilling and completion.
The basic cementing training is designed for personnel who are active in drilling and well integrity, but novices will also find great benefit.
