Micro Geopolymer Cement with Enhanced Physical Properties for Well Cementing

Ordinary Portland Cement (OPC) has been used widely in oil well industry. However, OPC creates high permeability between cement particles when exposes to HPHT environment inside the wellbore and also releases large amount of carbon dioxide (CO2) during manufacturing process. Previous research has...

Rheology and density test are compared at standard room conditions. The test results show the permeability of cement increase when increase the percentage of micro silica and curing duration. For static fluid loss test, increase in micro silica reduced the volume of filtrate. Two rheological model are observed from the samples; Power Law and Bingham Plastic Model. At standard room condition, the viscosity of cement slurry increased and density of samples decreased when increase the micro silica.
