“…The reason is that approximately 98% more CO 2 storage space was created by water extraction. Similar results of structurally dominated migration were observed in Case 5, where open model boundary conditions allowed for a greater injection rate (IEA 249 Greenhouse Gas R&D Programme, 2012; Liu et al, 2013). 250 Page 10 of 43…”

“…Because of the higher injection rates, pressure increases near the injection wells were expected to cause issues that may be alleviated by water extraction. Simulations under this scenario resulted in storage capacities of 551 Mt without water extraction, which increased to 637 Mt with water extraction, an increase of 16% (IEA Greenhouse Gas R&D Programme, 2012; Liu et al, 2013).…”

Water extraction from carbon dioxide (CO 2) storage reservoirs may be a method to enhance storage capacity and to actively manage storage reservoirs. Previous investigations into the use of water extraction have utilized homogeneous models to assess the feasibility of this technology. This study addressed water extraction based on four hypothetical CO 2 storage sites, which varied with respect to heterogeneous lithology, variable structure, and complex internal geometry. The simulation results showed the increased CO 2 storage capacity achieved through the use of water extraction varies greatly based on site conditions, ranging from 4% to 1300% in the four cases investigated. In all scenarios, water extraction reduced the maximum reservoir pressures approximately 10% to 20% during injection. In most scenarios, CO 2 plume movement could also be influenced through the use of water extraction. The last two aspects may be very beneficial for risk management and monitoring, verification, and accounting practices for all of the CO 2 storage projects.

“…Figure 17 shows a diagram of CO 2 -EWR technology. The operation of CO 2 -EWR could decrease formation pressure and avoid potential leakage through extracting formation water, thus it could further improve the storage efficiency and achieve higher security and stability of large-scale geological CO 2 sequestration [255]. Besides, the produced saline water could be used for drinking, industrial, and agricultural utilization after desalination treatment such as using a high-efficiency reverse osmosis system [252].…”

A Review of CO2 Storage in View of Safety and Cost-Effectiveness

et al. 2020

The emissions of greenhouse gases, especially CO2, have been identified as the main contributor for global warming and climate change. Carbon capture and storage (CCS) is considered to be the most promising strategy to mitigate the anthropogenic CO2 emissions. This review aims to provide the latest developments of CO2 storage from the perspective of improving safety and economics. The mechanisms and strategies of CO2 storage, focusing on their characteristics and current status, are discussed firstly. In the second section, the strategies for assessing and ensuring the security of CO2 storage operations, including the risks assessment approach and monitoring technology associated with CO2 storage, are outlined. In addition, the engineering methods to accelerate CO2 dissolution and mineral carbonation for fixing the mobile CO2 are also compared within the second section. The third part focuses on the strategies for improving economics of CO2 storage operations, namely enhanced industrial production with CO2 storage to generate additional profit, and co-injection of CO2 with impurities to reduce the cost. Moreover, the role of multiple CCS technologies and their distribution on the mitigation of CO2 emissions in the future are summarized. This review demonstrates that CO2 storage in depleted oil and gas reservoirs could play an important role in reducing CO2 emission in the near future and CO2 storage in saline aquifers may make the biggest contribution due to its huge storage capacity. Comparing the various available strategies, CO2-enhanced oil recovery (CO2-EOR) operations are supposed to play the most important role for CO2 mitigation in the next few years, followed by CO2-enhanced gas recovery (CO2-EGR). The direct mineralization of flue gas by coal fly ash and the pH swing mineralization would be the most promising technology for the mineral sequestration of CO2. Furthermore, by accelerating the deployment of CCS projects on large scale, the government can also play its role in reducing the CO2 emissions.

“…However, for the large-scale projects expected in a future CCS large-scale-deployment scenario, brine-extraction schemes are found to be beneficial in theory, allowing for higher storage capacity and improved injectivity (Buscheck et al, 2012) and reducing the risk of environmental impacts and induced seismicity (Birkholzer et al, 2012). The Gorgon Project in Australia will involve the possibility of brine extraction through four water production wells located to the west of the site (Flett et al, 2008;Liu et al, 2013). Dempsey et al (2014) recently went a step further and introduced the idea of "passive" injection.…”

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 technical gaps mentioned in 2005. A large body of research has been devoted to identify and verify the main processes that control CO 2 migration, trapping, and containment in deep saline aquifers. Much work has also been conducted to better understand the magnitude and implications of reservoir pressure buildup in response to large CO 2 storage projects. The aim of this paper is to provide a summary and overview of the most relevant recent (since publication of the IPCC SRCCS) literature and findings in the areas of CO 2 migration and pressure evolution. The paper first summarizes recent findings related to CO 2 plume migration and trapping, based on analytical and numerical modeling studies as well as several field injection tests conducted to examine the fate of injected CO 2 in various subsurface settings. The paper then discusses pressure effects as a function of space and time, including the effects of confinement (boundary conditions), highlights possible unwanted pressure impacts such as pressure-driven leakage and geomechanical damage, analyzes potential capacity constraints, reviews current concepts for pressure management, and closes with a discussion about use of pressure signals for advanced monitoring.
