Investigation of geopolymer as an alternative cementing material for wellbore applications

Abstract

This thesis contributes to the technological development of the carbon storage by geosequestration, which is one of the effective methods for mitigating global carbon emissions. Currently, Portland cement is used as the wellbore sealing material. However, leakages pathways are found to occur due to long-term exposure to CO2. This study investigates a new cementing material ‘geopolymer’. The demonstrated suitability of geopolymer as observed through the study will help successful implementation of geological storage of CO2 as well as the evolution of geopolymer as innovative cementing technology
