Abstract

The increasing carbon dioxide (CO2) emissions from industrial and energy activities have driven the development of Carbon Capture and Storage (CCS) technology as a key solution for climate change mitigation. Among various geological storage options, saline aquifers offer significant advantages due to their large storage capacity, wide distribution, independence from hydrocarbon value, and stable geological and geochemical conditions. The “AZ” Field, located near a power plant emitting 2.2 million tons of CO2 annually, was selected as the study site for CO2 storage. This study aims to analyze the trapping mechanisms and optimize the CO2 storage capacity (storativity) using a fully implicit integrated modeling approach. The methodology involves building a static and dynamic model of the Johansen Formation saline aquifer, and integrating well and surface facility models using the well designer and network designer features in tNavigator. A 140-year simulation was conducted, comprising 40 years of injection and 100 years of post-injection period. Simulation results show that the “AZ” Field can store up to 83.9 Mt of CO2, predominantly through solubility/residual trapping mechanisms, in addition to structural trapping. No leakage was observed to the surface, indicating that caprock integrity remained intact throughout the simulation period. The fully implicit integrated modeling approach effectively captured the dynamic interactions between the reservoir, wells, and surface facilities, supporting the feasibility of the “AZ” Field as a safe and sustainable CO2 storage site.

Abstract

This study aims to determine the inter-floor shift due to earthquake spectrum response using nonlinear pushover analysis in a clinic building located in the Cimandiri Fault Zone as a basis for healthcare infrastructure management. This is very important because healthcare infrastructure is a place that must be available in any condition, even after an earthquake disaster. The Sukabumi area is an area located in the Cimandiri Fault Zone, so buildings in this area must be specifically designed to remain intact during disasters, especially earthquakes that often cause building damage. The research object that is the case study in this study is a 4-story clinic building that uses a reinforced concrete structure. The method used in the earthquake spectrum response analysis refers to SNI 1726:2019 and SNI 2847:2019, which have available spectral response webs, while the nonlinear pushover analysis uses the ATC-40 and FEMA-440 methods implemented in ETABS. The results of the analysis show that the inter-floor shift on the second and third floors exceeds the specified service limits, so it can be stated that the clinic building structure service in this case study requires damage control (DO). This can be seen based on the analysis results that the inter-floor shift of 201 mm in the X direction and 190 mm in the Y direction can cause moderate damage that can be repaired, so that health infrastructure service management is very necessary. Controlling recurrent damage due to earthquakes can be done with three retrofit scenarios consisting of the addition of shear walls, column coating, and steel reinforcement. The three scenarios are assessed and ranked based on the reduction of shifts, repair duration, and functional disruption. The addition of shear walls is the main recommendation without disrupting functionality, while column coating and the addition of steel reinforcement can disrupt health service operations. Retrofit scenarios can be recommended to support a sustainable health service infrastructure system in earthquake-prone areas. Earthquake spectrum response is a key factor that needs to be reviewed in building damage analysis as a basis for risk control management of health service infrastructure.
