The well cementing is important during the extended reach well drilling and the completion,
whereas the displacement efficiency and the interface stability are important to guarantee …

A successful primary cementing job requires an efficient fluid displacement process in order
to place cement in the annulus between a casing or liner and the formation around the …

Cement plays an integral role in maintaining well integrity throughout the life cycle of a well.
Successful cementing jobs provide good zonal isolation and ensure strong bonding of …

The success of a primary cementing job is based on high fluid displacement efficiency inside
the casing and the annulus. However, high displacement efficiency in real wells is not easily …

Primary cementing is a crucial task in the completion of oil and gas wells, as it is potentially
meant to provide zonal isolation, and prevent uncontrolled flows and environmental …
