Engineering Visual Presentation E11: Deployment of a locally sourced CO2 and corrosive-resistant cement system

Engineering Visual Presentation E11 Australian operators increasingly require cement systems that can preserve long-term well integrity in the presence of CO2, acidic fluids, magnesium-rich brines, and sulfate-bearing environments, while also remaining practical to source and deploy across remote operations. This paper presents the development and field use of a corrosion-resistant blend cement system formulated predominantly from locally sourced materials. Laboratory qualification showed markedly lower mass loss than conventional Class G cement during acid-brine exposure and retention of compressive strength after prolonged wet CO2 challenge. Field applications in mining, monitoring, injection, and plug-and-abandonment work confirmed that the system could be tailored for different operational requirements while maintaining corrosion-resistant performance and supply-chain practicality.
