| Summary: | For the past decades, the rise in concerns of carbon dioxide level in the atmosphere has escalated. Hence, it to actively think of alternative solutions on how to manage carbon dioxide that are often released from fuel consumption and petroleum production. One of the most discussed solutions is geological storage in depleted oil and gas reservoir. Hence, this study discusses the suitability of Malay Basin as a potential geological storage for carbon dioxide and storage capacity estimation by using Ogawa methods. The potential injection zone was identified and estimated Jerneh depleted gas field can store up to 150 MMton of carbon dioxidefor the sand Group D and E are main reservoirs (coastal plains) and shale in groups A and B are caprock (shallow marine deposits). Northern and Central Provinces of Malay Basin is found to be the most suitable subregion for carbon dioxide geological storage purpose due to abundant and enormous underdeveloped high contaminant field for injection of carbon dioxide rank down for priority. Site selection and characterization for CO2 storage in the offshore region of Malay Basin were carried out with reference to ISO 27914: 2017. Then Western Bujang and Jerneh gas field were selected for the potential CO2 storage sites because of high-ranking resulting from storage capacity and safety assessments. The study focused on characterization of geological complex of both sites to determine injection formations and, seal rocks and proceeded assessments of capacity and injectivity of the Bujang West saline aquifer. |
