Simulation On Geological Storage Of Carbon Dioxide In The Gulf Of Thailand.

Abstract

Climate change is one of the most concern problems currently because of the increase of the amount of greenhouse gases in the atmosphere. CO2, the most important component of greenhouse gases, comes from industries like power generation. Carbon capture and storage (CCS) is the practical technology to mitigate CO2 especially geological storage. In Thailand, the main potential of geological storage is in the Gulf of Thailand. However, the research on this in Thailand is scarce. Consequently, this work is focusing on the simulation of CO2 geological storage in formations at the Gulf of Thailand. The storage capacity and the fracture pressure have been estimated. Also, the pressure buildup and plume migration have been simulated with various conditions. CO2 injection is used from 1,000-4,000 tons per day with the depth from 2,160 – 2,510 meters and the results are studied for 1-50 years for monitoring period. The results show that CO2 storage in this area has potential with the formation characteristics. Moreover, pressure buildup and plume migration are illustrated for the period of 50 years. This study can contribute as a fundamental knowledge for CO2 storage in an offshore area in Thailand.
