Abstract: Oil well cementing has always been a vital, indispensable, and costly part of drilling and wellbore completion. Ensuring high-quality cement slurry is crucial for safe and economical oil production over the well’s entire lifespan. However, designing the optimal cement slurry for oil wells is challenging due to the several parameters that must be considered to achieve successful cementing. This study examines the effects of water-cement ratio and temperature on the density and rheological properties of class G cement slurry. Four cement samples with water-cement ratios of 0.34, 0.39, 0.44, and 0.49 were tested at 25 °C and 45 °C. A homogenous mixture of the slurries without additives was obtained by following American Petroleum Institute (API) standards. The study showed that the density of oil well cement slurries decreased as the water-cement ratio increased. The rheological properties of the slurries decreased with higher water-cement ratios. However, the rheological properties of each water-cement ratio increased as the temperature rose. This demonstrates that the water-to-cement ratio and temperature strongly influence the rheological properties of oil well cement slurries.
