Abstract
This study focused on the target injection layers of deep saline aquifers in the Shiqianfeng Fm. in the Carbon Capture and Sequestration (CCS) Demonstration Projects in the Ordos Basin, northwestern China. The study employed a combination method of experiments and numerical simulation to investigate the dissolution mechanism and impact factors of CO2 in these saline aquifers. The results showed (1) CO2 solubility in different types of water chemistry were shown in ascending order: MgCl2-type water < CaCl2-type water < Na2SO4-type water < NaCl-type water < Na2CO3-type water < distilled water. These results were consistent with the calculated results undertaken by TOUGHREACT with about 5% margin of error. CO2 solubility of Shiqianfeng Fm. saline was 1.05 mol/L; (2) compared with distilled water, the more complex the water’s chemical composition, the greater the increase in HCO3 −concentration. While the water’s composition was relatively simple, the tested water’s HCO3 −concentrations were in close accord with the calculated value undertaken by the TOUGHREACT code, and the more complex the water’s composition, the poorer the agreement was, probably due to the complex and unstable HCO3 − complicating matters when in an aqueous solution system including both tested HCO3 −concentration and calculated HCO3 −concentration; (3) the CO2 solubility in the saline at the temperature conditions of 55 °C and 70 °C were 1.17 and 1.02 mol/L. When compared with the calculated value of 1.20 and 1.05 mol/L, they were almost the same with only 1 and 3% margin of error; concentrations of HCO3 − were 402.73 mg/L (0.007 mol/L) and 385.65 mg/L (0.006 mol/L), while the simulation results were 132.16 mg/L (0.002 mol/L) and 128.52 mg/L (0.002 mol/L). From the contrast between the tested data and the calculated data undertaken by the TOUGHREACT code, it was shown that TOUGHRACT code could better simulate the interaction between saline and CO2 in the dissolution sequestration capacity. Therefore, TOUGHREACT code could be used for the inter-process prediction of CO2 long-term geological storage of CO2; (4) The Ca2+ concentration and SO4 2−concentration in saline water had less effect on the solubility of CO2 and HCO3 −concentration. In addition, TDS and pH values of saline affected not only the solubility of CO2, but also the conversion of CO2 to HCO3 − due to that they can affect the activity and acid-base balance. So in fact, we just need to consider that the TDS and pH values are main impact factors in the dissolution sequestration capacity of CO2 geological sequestration in deep saline aquifers.

Enhanced oil recovery through carbon dioxide injection (CO2-EOR) data has made it possible to estimate the CO2 geological storage in the oilfields of the Songliao Basin, northeastern China. The storage capacity of CO2 in oilfields was determined and the results show that the theoretical storage capacity of CO2 in the oilfields of the Songliao Basin is 2.36 × 109 t, and the effective storage capacity is 0.59 × 109 t with an effective coefficient of 0.25. Among the tectonic units, the central down...

Saline formations are considered to be candidates for carbon sequestration due to their great depths, large storage volumes, and widespread occurrence. However, injecting carbon dioxide into low-permeability reservoirs is challenging. An active demonstration project for carbon dioxide sequestration in the Ordos Basin, China, began in 2010. The site is characterized by a deep, multi-layered saline reservoir with permeability mostly below 1.0 × 10−14 m2. Field observations so far suggest that only...

A carbon dioxide (CO 2 ) capture and storage demonstration project was started in 2010 by injecting around 100 000 tonnes of super‐critical CO 2 per annum into a set of very low‐permeability sandstone at depths of more than 1600 m in the northeastern Ordos Basin, China. Based on the site‐specific geology and the observational data, a numerical injection model was developed in order to understand the hydrodynamic behavior of CO 2 in the subsurface for evaluating reservoir performance. The results...

Abstract The dissolution of carbon dioxide (CO 2 ) in deep saline aquifer water is recognized as one of the fundamental mechanisms in the subsurface for storing significant quantities of CO 2 . One fundamental physical effect of CO 2 dissolution is the slight increase in water density in the layer in contact with the buoyant free-phase CO 2 plume. Under specific conditions, this may lead to gravitational instability and the onset of free convection, significantly accelerating the dissolution of ...

Abstract In 2005, the IPPC Special report on carbon dioxide capture and storage (SRCCS) summarized the state of knowledge about CCS as an emerging technology for reducing CO 2 emissions to the atmosphere. At the time of writing, the emphasis of the SRCCS was on understanding the fate of injected CO 2 whereas less attention was paid to effects of pressure buildup associated with CO 2 injection. Since then, the CCS community has significantly improved the knowledge base and addressed many of the t...

Abstract At the time the IPCC Special Report on Carbon Capture and Storage was published in 2005, the concept of CO 2 storage efficiency was not introduced yet and, consequently, no numerical values were published in the literature. CO 2 storage efficiency is defined as the ratio of the volume of CO 2 injected into an aquifer rock volume to the pore space in that volume and this concept has been first introduced in 2007 in regional-scale assessments of storage capacity in the United States and E...

Carbon capture and storage (CCS) is the only viable technology to mitigate carbon emissions while allowing continued large-scale use of fossil fuels. The storage part of CCS involves injection of carbon dioxide, captured from large stationary sources, into deep geological formations. Deep saline aquifers have the largest identified storage potential, with estimated storage capacity sufficient to store emissions from large stationary sources for at least a century. This makes CCS a potentially im...

Abstract A comparison of the geochemical changes induced in sandstone by either pure or impure CO 2 at geological CO 2 storage conditions was investigated. Samples of Berea Sandstone were batch reacted in 1% w/v NaCl brine saturated with pure CO 2 or mixed SO 2 –CO 2 gas for 360 h at 50 °C and 10 MPa. Geochemical analysis of incremental water samples showed increases in the concentrations of elements such as calcium, magnesium, iron, manganese, and silicon throughout experiments, likely being th...

Abstract Carbon dioxide (CO 2 ) storage security is a key issue in CO 2 geological storage (CGS). A three-dimensional (3D) conceptual reservoir model of the Shenhua CO 2 geological storage site in the Ordos Basin has been used to investigate the impact of reservoir formation dip and the influence of enhanced permeability fault zones on CO 2 storage and migration security. A total of 8 simulations were carried out using the TOUGH2 integral finite difference modelling code with the ECO2N fluid pro...

Abstract The safety of CO 2 geological storage is a key problem that hinders its implementation. In particular, the formation dip angle and salinity can directly affect the spatial migration distribution, storage form and storage amount of CO 2 . A three-dimensional simulation model was established to evaluate the effects of the formation dip angle and salinity on the safety of CO 2 geological storage. The simulation results showed that a larger dip angle resulted in a greater CO 2 migration dis...
