3D Modeling of CO2 Geological Storage of Songkhla Sub-Basins in the Lower Gulf of Thailand

Abstract

The CO₂ geological storage of is a one high efficiency for CO₂ disposal method from the energy sector especially production of electricity by using fossil fuels. This method can help mitigate global warming will be occurring. The first aim of article to study a construction 3D geological model for assessment CO₂ storage capacity and direction of CO₂ movement, case in the Songkhla Sub-basins in the Lower Gulf of Thailand. The Sonkhla sub-basins consist of Bua-Ban, Benjarong and Songkhla. In the article focus on Bua-Ban was devided by Songkhla Lower Miocene (SLM) and Songkhla Lower Oligocene (SLO). 3D geological CO₂ storage model of sites were constructed by a public data that will be accessed like a data consist of a depth structure map, geologic setting and reservoir properties. The second aims to study a risk of seismic hazard from CO₂ injection by planning multi wells CO₂ injection in the reservoir. As the results, the accumulation of CO₂ storage capacity from 3D geological model from SLM and SLO approximate 5.69 Mton-CO₂ based on 3D geological model was constructed by limit of data. 3D geological model can be used to investigation CO₂ migration and pressure build up in the reservoir during CO₂ injection on time lapse for protection risk of CO₂ leaking out of reservoir. In addition, Songkhla sub-basins which site safety for seismic induced and effective geological CO₂ storage based on injection rate of CO₂ undertaken initial pressure.
