| Samenvatting: | Title screen This study aimed to develop a new lightweight cement composition (LCC) for low formation pressure and high-temperature geothermal wells over a wide temperature range. The formulation utilized a novel Graphene-Alumina (GA) nanohybrid synthesized via co-precipitation, combined with Hollow Glass Beads (HGB-5), a cement density reducer (HCDR-10), and a liquid cement extender (PPMB-40). The research focused on optimizing key cementing performance parameters including mechanical strength, fluidity, rheological, and thermal properties to meet design requirements for unconventional geothermal reservoirs. The addition of 5 % GA nanohybrid optimized slurry density to 1.12 g.cm−3 and enhanced compressive strength by 103.26 % at 100 °C compared to the blank, due to improved hydration. Fluid loss decreased by 81.5 % in slurries with 5 % GA, while thermal conductivity increased by 22.1 % at 120 °C. Overall, the GA nanohybrid significantly improved the stability, durability, and performance of lightweight cement formulations for unconventional, high-temperature geothermal and oil wells Текстовый файл AM_Agreement |
