The hydrated products of Class G cement drastically change after exposure to CO 2-
saturated brine, compromising the cement physical properties, especially, the compressive …

Carbon fiber (CF) pretreated with oxygen plasma and modified with ethanol plasma was
employed to improve the mechanical properties of lightweight oil well cement (LOWC) …

The physical properties of the oil well cement are significantly changing after reacting with
CO 2-saturated brine. In this study, the effect of incorporating the laponite on the properties …

In this study, silica (SiO 2) nanoparticles were deposited on the surfaces of micro-synthetic
polypropylene (PP) fibers through the sol-gel process and combined with Alumina …

One of the critical issues that occur in many oil and gas wells is the failure of the cement
sheath because of debonding from the casing string or from the formation. This results in the …

In the drilling and production operations, the effectiveness of cementing jobs is crucial for
efficient progress. The compressive strength of oil well cement is a key characteristic that …

Background: Cementing of the production column is an important stage of well completion,
which in turn requires the correct selection of the formulation of grouting solutions that …

This study evaluates the use of the synthetic polypropylene fibers (SPF) to mitigate Class G
cement strength retrogression under high-temperature conditions. Cement samples with …

Cement is a major component in oil and gas drilling operations that is used to maintain the
integrity of boreholes by preventing the movement of formation fluids through the annular …

An economical and cost-effective replacement for conventional building materials is
Compressed Stabilized Earth Block (CSEB). However, they are vulnerable to erosion and …
