Safety-based Injection Strategy for Carbon Dioxide Geological Sequestration in a Deep Saline Aquifer with Complex Sandstone-shale Sequences: A Case Study from Taiwan

Carbon Capture and Storage (CCS) is one of the effective means to reduce the carbon dioxide concentration in atmosphere. Deep saline aquifer is the most potential storage sites because of its wide spread and the huge storage capacity. The storage capacity of deep saline aquifer was determined by hydrogeological parameters of the assessed aquifer. Spatial discretization method based on the geostatistical method takes account of the spatial variability of hydrogeological parameters involved in capacity assessment, which applied by inputting the value of hydrological parameters of every cell and calculating the storage capacity of each cell. The total storage capacity in assessed area was the summation of all cells. In the Central Depression of Songliao Basin, the theoretical carbon dioxide storage capacity of deep saline aquifers was estimated as 81.80Gt with spatial discretization method. Compared with the other methods, this method can reflect the spatial characteristics of the carbon dioxide storage capacities and was more precise.

Locally Conservative

Purpose In this work, it is presented a locally conservative multiscale algorithm accounting the mineralization process during the supercritical carbon dioxide injection into a deep saline aquifer. The purpose of this study is to address numerically the geological storage of CO2 in a highly heterogeneous reservoir, leading with interactions among several phenomena in multiple scales. Design/methodology/approach This algorithm have features that distinguish it from the presently available solvers which are: (i) an appropriate combination of a coupled transport system solver using a high-order non-oscillatory central-scheme finite volume method and, elliptic numerical approach applying a locally conservative finite element method for Darcy’s law and, (ii) the capability of leading with interactions among several phenomena in multiple scales. Findings As a result, this approach was able to quantify the precipitation of the carbonate crystals at the solid interface.
