As a deep saline aquifer, the Tai‐hsi Foreland Basin in western Taiwan is regarded as an excellent locality to sequester the huge carbon emission from domestic coal‐fired power plants. Existing geological data show that an intra‐formational seal capability characterized by multilayered shale baffles can act as the primary or ultimate cap system. In this study, the relevant ranges of rock parameter of porosity (20∼35%) and permeability (0.0001∼1300 mD), respectively, for the storage layers (sandstone) and seals (shale) have been selected according to large amount of laboratory core test from a nearby pioneering 3000 m drilling and sampling within the southern flank of the Tai‐hsi Basin. Comprehensive geological models considering both homogeneous and heterogeneous cases, and a typical plume migration scenario under a single‐well injection were simulated under a 20‐year continuous injection (1 MtCO2 per year) followed by post‐injection monitoring up to 1000 years. Corresponding 2D maximum horizontal migration distances (MHMD) of CO2 plume in the storage reservoir were calculated with respect to a homogeneous reservoir model and its heterogeneous counterparts. In addition, the induced pressures at critical monitoring points were also evaluated and compared. As a consequence, the ubiquitous shale baffles of intra‐formational seal in a heterogeneous saline aquifers were proven to be a successful trapping mechanism controlling the migration distances of lateral and upward movement. Furthermore, safe carbon storage operation within Tai‐hsi Basin with formation depth range about 2135 to 2450 mRT can be ensured by checking statistically the calculated maximum MHMD and the induced pressure magnitude. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…These cores were sampled and extensively examined by lots of laboratory analysis and testing. According to some preliminary and/or comprehensive results, it is confirmed that, many target sandstone rich formations or deep saline reservoirs within Tai-Hsi Basin are very suitable [8,9] for developing geological storage [3,[5][6][7]. Table 1 shows the on-site stratigraphic sequence and the thickness (m) of all the major formations revealed in the recently completed M-1 well.…”

Abstract:The intra-formational seal capability was characterized by multi-layered shale baffles to act as the primary or ultimate cap system, were taken into account by homogeneous and heterogeneous models, respectively. In this study, the relevant ranges of input parameter of porosity (20%-35%) and permeability (0.0001-1,000 mD), respectively for the sandstone (storage layers) and shale (seals) have been selected, according to results of large amount of laboratory core, test from pilot 3,000 m drilling within Tai-Hsi Foreland Basin in Western Taiwan. By a comprehensive geological model, typical single well injected plume migration scenarios were stochastically simulated which covered a 20-year continuous injection (one Mt-CO 2 per year) followed by a 1,000-year post-injection monitoring. The corresponding 2-D MHMD (maximum horizontal migration distances) of CO 2 plume in the storage reservoir had been calculated with respect to heterogeneous reservoir models and their homogeneous counterparts. Moreover, the induced pressures at critical monitoring points above the injection zone were also evaluated. As a result, the shale baffles of intra-formational seal in a saline aquifers are proven to play a vital role, and capable of ensuring the safe carbon storage operation within a basin scale with a depth range about 2,100-2,500 mRT.

“…Results from a case study currently conducted on China's first demonstration CCS project "Shenhua CCS demonstration project" showed that the project could face risks from many aspects such as technology, health, safety and environment, market, energy and resources, as well as policy and regulations (Xuan, 2014). In Taiwan, the Changhua Coastal Industrial Park site, located in the center of the west coast was viewed as a good potential storage site because of its proximity to massive stationary sources of CO 2 emissions from nearby petrochemical and coalfired power plants (Yu et al, 2011). However, leakage from subsurface storage sites is one of the main concerns of the CCS technology (Peter et al, 2012).…”

Excess carbon dioxide emission was considered as the most important cause of increased trend of global warming. Significant amounts of research were devoted to the reduction of CO 2 emission and CO 2 sequestration. Sequestration of CO 2 in empty oil reservoirs was considered as one of the most promising options. However, the effects of metal release and mobility as a result of CO 2 injection were not studied in detail, particularly under super-critical CO 2 (scCO 2 ) conditions. In this study, the release of selected metals immersed in distilled water for varying amounts of time in the absence and presence of scCO 2 was assessed in simulated conditions at 90°C and 24 MPa. Significant increases in dissolution of Fe, Sr, and Ba by 3, 8, and 24 times were found when the storage rock sandstone or caprock shale was immersed in DI water for different time period. However, in the presence of scCO 2 , the dissolution of these metals was reduced by 80% for Fe, suggesting permanent sequestration of scCO 2 into carbonate minerals. The trend in changes of pore water chemistry in the sandstone and shale after being immersed in DI water showed dissolution of Sr-bearing mineral and precipitation of Ba-bearing mineral.
