碩士 / 國立中央大學 / 地球物理研究所 / 99 / Geological storage of carbon dioxide is the one of most effect and direct method to reduce carbon dioxide (CO2) in the atmosphere. This study reports the use of reflection seismic and well-log data to investigate possible and suitable storage sites of CO2 and to estimate potential storage capacity of CO2.
In the offshore area between Taichung and Changhwa, Nanchuang Formation and Kueichulin Formation are good CO2 reservoirs as they contain multiple layers of sandstones (around 50-400 meters thick) with their formation top lying at depth 700-2800 meters. Those porous sandstones are capped by Chinshui Shale. All the stratigraphic units deepen toward the east and the north due to orogenic loading in the study area. The injected CO2 will migrate toward the Taiwan Strait in the west along the deeper CO2 reservoir. Because faults mostly occur within the sequences below Kuanyinshan Sandstone and there are less active structures in the study area, this area will be a suitable CO2 storage site. However, there probably is an N-S fracture in the eastern part of the study area. We should observe and take notice of the fracture more. If it doesn’t exist, this region is a good choice to store CO2 certainly.
This study use the method that suggested by Tanaka et al. (1995) and USDOE (2007) to estimate potential geological storage of CO2 in the offshore area between Taichung and Changhwa. The CO2 storage capacity in this region including the area with Chinshui Shale is around 590 and 640 megatons as estimated by Monte Carlo simulation, individually.
