Abstract

Cement integrity in oil and gas well cementing operations is critically important, particularly under high-pressure and high-temperature (HPHT) conditions and in the presence of gas indications. The main challenges include degradation of cement quality due to changes in slurry physical properties such as strength retrogression, as well as the risk of micro-annulus formation and channeling that can lead to gas migration. This study aims to optimize slurry design to enhance cement integrity and prevent gas migration. The method employed is a laboratory-based experimental approach with quantitative analysis of slurry physical properties. The results indicate an optimal formulation with a density of 17 ppg, pumpable rheology, filtration loss of 35 ml, thickening time of 6 hours 30 minutes, 0% free water, SGS transition time of 2 minutes (100–500 lb/100 ft²), cement expansion of 0.651%, compressive strength of 4910 psi, and cement hydration that passed gas migration testing. This formulation is proven to be effective in maintaining cement integrity under high-temperature conditions.
