Abstract

Cumulative fluid production during 2009 - 2021 in the Betung Field, which is the research location and is located in the Jambi sub-basin-South Sumatra Basin (Barber et al., 2005), amounted to 277,923.52 MBbl. The relationship between porosity and permeability can be said in general that if the porosity is greater, the permeability will be greater, but in reality it will be found that certain layers will have large porosity but small permeability, such as in layers containing clay or shale. Mineralogical composition plays an important role, especially with regard to clays, involving several compositions including illite, smectite, kaolinite and chlorite. The presence of quartz and feldspar increases permeability, while clay minerals and calcite tend to have the opposite effect (Jose M. Carcione et al., 2019). The analysis carried out included XRD analysis to determine the mineral composition of the reservoir sandstone of the Airbenakat formation, rock quality analysis (porosity and permeability), well log analysis and then the overall analysis results were linked to production data. Based on XRD analysis, petrophysical analysis of wells 209 and 217 in the Betung field, Airbenakat formation, Jambi sub-basin, South Sumatra basin, the results of XRD and petrophysical analysis show the presence of clay content consisting of Kaolinite, Illite, Smectite and Chlorite which has an influence on reservoir quality, especially permeability, where the greater the clay content, the more obstructed fluid flow is.

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.
