Oil Well Cementing - an overview | ScienceDirect Topics

Oil-well cementing is the process of pumping cement slurry down the annulus between the casing and wellbore. This is known as the primary cementing. The objective is to form a cement sheath that will ensure zonal isolation, support, and protect the casing (Vuk et al., 2000). Secondary cementing is any cementing operation performed after primary ...
