| dc.description.abstract | The national energy policy aims at replacing nuclear energy with green energy. However, green energy is not a base-load energy, it still needs to rely on fossil energy to stabilize the power supply. Therefore, fossil-fuel power generation will continue to play an important role in the future. The technology which captures carbon dioxide in real time and seals it on site can simultaneously solve the problem of pollution, and also maintain the national energy structure. This study collects the seismic and geological data of the Jangbin Industrial Area and the Taichung Power Plant along the Taichung-Changhua coast. We will compare the advantages and disadvantages of the two sites as CCS sites
This study used high-resolution reflection seismic survey to investigate underground structures suitable for carbon dioxide sequestration as a reference for drilling and future monitoring. In the field, the vibrator source is used with 240 channels, 4m spacing, and 30 folds. A total of 11 reflection seismic lines along the coastline are collected, with a total length of 30 kilometers. The well data from CPC’s WangGon Well and Taipower’s JangBin Well are used to predict the future Taichung-Port Well, which further helps the interpretation of the seismic data gathered at the Taichung Port area.
The following conclusions are obtained: 1) Using the stratigraphic formations revealed by WangGong Well and JangBin Well, the possible stratigraphic patterns of the future Tachung-Port Well are estimated, which are confirmed by the seismic reflection profiles of this study. 2) Six cross-tied surveying lines in the Jangbin Area establish a complete 3D underground stratigraphic distribution. The strata have a strike of north 8 degrees to east and a dip 3.8 degrees east. Three CO2 storage layers are at the depths of 2140~2450m, 2510~3140m, and 3300~3500m. 3) Five survey lines in the Taichung-Port Area expose similar seismic reflection phases. After comparing with the Taichung-Port Well, its CO2 storage layers are at the depths of 2300~2700m, 2850~3350m, and 3500~3900m. 4) The stratum of the TaiChung-Port Area is 250~400 meters deeper than that of the Jangbin Area. However, the available layer thickness is about 50 meters larger, and the reflective phase indicates better sandstone content. 5) The survey area has simple structure and the stratum is flat. No faults and layer disturbances are found. The conditions of the sedimentary structure make the area suitable as a CCS site.
