Geological storage of carbon dioxide is the process whereby CO2 captured and separated from a source is transported and injected into the geological subsurface for long-term removal from the atmosphere. It is analogous to natural gas being trapped in the deep subsurface in hydrocarbon pools for geological time periods. The main geological constraints for finding the right place to store CO2 include a porous and permeable reservoir rock to allow injection at the desired rates (injectivity) and storage of the desired volume (storage capacity), overlaid by an impermeable seal rock to retain the injected CO2 in the geological subsurface (containment security). Two major categories of the storage target are (1) deleted oil and gas fields and (2) saline aquifers. But geological carbon storage must be conducted where it will not adversely affect other sedimentary basin resources. Sedimentary basins can host different natural resources that may occur in isolated pockets, across widely dispersed regions, in multiple locations, within a single layer of strata, or at various depths. The primary resources to consider are groundwater, conventionally and unconventionally trapped oil, gas, coal, and geothermal energy. Other resources that may also need consideration include gas hydrates, mineral and oil sands, potash, uranium, diamonds, and other sediment hosted mineral deposits. Understanding the nature of how these resources are distributed and hydraulically connected in the subsurface is fundamental to managing basin resource development together with carbon dioxide storage. Surface infrastructure and land use (e.g., national park, towns, and cities) also impact subsurface resource development options and must be considered in any basin resource management strategy.
Hydromechanical properties of sedimentary rock under injection of supercritical carbon dioxide

Sedimentary basins are formed by gradual deposition and compaction of sediments eroded from mountains. As a result, they generally consist of alternating layers of coarse sediments (sandstone) and fine textured sediments (clay, shale and evaporites). The sandstone layers with high permeability will provide storage for CO2, while the shale layers with low permeability will act as a barrier to prevent CO2 migration to potable groundwater sources and even to the surface.

Hydrocarbon preservation and formation water geochemistry in abnormal pressure system in the Bawu area of Lishu depression, Songliao Basin, China

The isotopic and chemical composition of formation water are critical on the geochemistry, hydrogeology and tectonic evolution of basins. The geochemistry of formation water can provide insights into myriad of important processes occurring in the basins, especially the generation, transport and accumulation of hydrocarbon (Kharaka and Hanor 2014). The abnormal system in sedimentary basins has been an important issue in the field of petroleum exploration because its high relevance to the migration and accumulation of hydrocarbon. Numerous studies reported the existing of such a model in Lishu Depression of Songliao Basin, where a subnormal pressure system is present in the Bawu area of this depression. However, to date, the research on hydrocarbon preservation associated with geochemistry of formation water in abnormal pressure system is scarce, and most studies merely focused on the sedimentary characteristics, tectonic evolution and hydrocarbon accumulation.
Seismic Aggravation in Shallow Basins in Addition to One-dimensional Site Amplification

Sedimentary basin (or valley), which is a topographic depression filled with sediments over geologic time, is a highly present geological formation. Basin effects have received much attention as they not only involve spatially aggravated and elongated ground motions but also because of the fact that sedimentary basins accommodate some of the world’s economic powerhouses, e.g., Tokyo, Los Angeles, Taipei, and Mexico City.
