Recently, there has been wide concern about the mechanical properties of the repair
interface for the magnesium phosphate cement mortar as a repair material with Portland …

This paper focused on fracture problem about interfacial transition zone (ITZ) formed after
repairing between magnesium phosphate cement (MPC) mortar and old Portland cement …

In the oil and gas industry, a successful zonal isolation, which is the primary goal of
cementing, is achieved by a strong bond at the cement-rock and the cement-casing …

The performance of oil‐well cement is altered if contaminated by spacers. Very few studies
in the literature are found on this topic, in particular for newly developed microemulsion …

From spud to plug, the ability for cement to provide an adequate seal with the casing is of
paramount importance in preventing the migration of fluids along the wellbore and to the …

This paper presents a method of using particle probe scanning force microscopy to measure
the adhesion between steel microspheres and cement pastes. Particle probes were …

The primary function of natural gas well cementing is to provide downhole zonal isolation.
However, the residual non-aqueous drilling fluid in cement and on the surface of the casing …

It is crucial to assess the bond strength of the cement–formation interface while developing
novel cements for efficient zonal isolation. An integrated method is presented to investigate …

Cementing plays a critical role in well construction. An unsuccessful cementing job could
impose severe safety, pollution and economical risks on the company. Experimental studies …

Oil well cleanup fluids (pre-flushes) are intermediate fluids pumped ahead of the cement
slurry; they are able to clean the well walls by removing the filter cake formed by the drilling …
