It has been demonstrated that nanoparticles have made some progresses in the operational characteristics of conventional cement. Various technologies have been developed to solve gas migration where is an important task to design a cement slurry that do not let the hydrocarbon fluid migrate from the cement after its hydration. This research, via 13 experimental attempts, showed that great improvement in compressive strength and rheological properties of cement slurry appears after addition of silicon dioxide nanomaterial to the slurry, on the other hand it did not make any significant change in free water content of the cement and fluid loss. In the case of static gel strength analyzers (SGSA) test, transient time followed a decrementing pattern by increasing nanoparticle. As a result, it met the vital goal in drilling industry via deep reduction in gas migration rate and solves the foregoing problem without having any negative effects on the other properties of cement slurry such as thickening time. Moreover, Mohr circles analysis demonstrated that higher compressive strengths are achieved by adding nanoparticles, especially in the absence of anti-gas migration additive. %U https://www.echemcom.com/article_96607_25ccc145ef5e86d7d3b32358e53b5b89.pdf
