Abstract

Well cementing is an essential process for well stability, involving the pumping of cement slurry into the annulus between casing and formation. This prevents fluid movement and provides support for the casing. Therefore, various additives are employed in cement design to meet downhole specifications. In this paper, experimental work has been performed to study the possibility of using perlite as an additive to improve the properties of high-density cement. Base cement sample (without perlite) and perlite cement sample (with 4% by weight of cement of perlite) were prepared under high pressure and high temperature to examine their effect on the oil-well cement properties such as compressive strength, viscosity, permeability, and particles settling. The findings demonstrated a significant enhancement in oil-well cement properties with the addition of perlite. Integrating perlite into the cement composition increased its strength, leading to an 88% improvement in compressive strength compared to the base cement. The inclusion of perlite particles resulted in a 30% reduction in the viscosity. Furthermore, the addition of perlite decreased the cement permeability by 66%. Additionally, perlite effectively minimized the particles settling along the cement column to a minimal percentage of 0.1%.
