“…Combined with a selection indicator evaluation system for potential storage sites, the standardization of the CCS in China has a good foundation [20,21,113,114]. A preliminary evaluation of the CO 2 storage potential in the saline formations at a depth of 1-3 km showed a capacity of 1.435 × 10 Table 1. the studies on CO 2 sequestration in saline formations [117][118][119][120][121][122][123][124], the first full chain CCS project in China was successfully launched in the Ordos Basin with a storage target of 0.1 million tons of CO 2 injected in 2010 [125][126][127][128][129][130]. about 70% of the oil production comes from nine oilfields, that is, Changqing, Tarim, Daqing, Shengli, Yanchang, Bohai, Liaohe, Zhongyuan, and Jilin.…”

Carbon capture, utilization, and storage (CCUS) is a gas injection technology that enables the storage of CO 2 underground. The aims are twofold, on one hand to reduce the emissions of CO 2 into the atmosphere and on the other hand to increase oil/gas/heat recovery. Different types of CCUS technologies and related engineering projects have a long history of research and operation in the USA. However, in China they have a short development period ca. 10 years. Unlike CO 2 capture and CO 2 -EOR technologies that are already operating on a commercial scale in China, research into other CCUS technologies is still in its infancy or at the pilot-scale. This paper first reviews the status and development of the different types of CCUS technologies and related engineering projects worldwide. Then it focuses on their developments in China in the last decade. The main research projects, international cooperation, and pilot-scale engineering projects in China are summarized and compared. Finally, the paper examines the challenges and prospects to be experienced through the industrialization of CCUS engineering projects in China. It can be concluded that the CCUS technologies have still large potential in China. It can only be unlocked by overcoming the technical and social challenges.

The abandonment process is a highly important part of project management for CO2 capture and storage (CCS) projects. For the first full procedure of a CO2 geological storage demonstration project in a deep saline aquifer in China, this paper describes the abandonment process of a CO2 operating well. The key idea that we advance is that wellbore integrity tests should be conducted before the abandonment, and consideration must be given to the CO2 corrosion resistance materials, the design method of sealing the plugs, monitoring tests (such as pressure tests), and the use of a long‐term monitoring system (such as the original pressure test and a packer isolation test every year). According to Chinese regulations and related experience in the oil and gas industry, the factors chosen are the pressure factor, cap rock, potable water layer, unexploited resource layer, suspected leak path, perforated zone, productive hydrocarbon zone without perforation, and water‐injection and waste‐water treatment layers. We intuitively evaluate and quantify the plugged zones using the modified analytical hierarchy process (M‐AHP) method to determine the positions of the plugs. Next, referring to the Chinese regulations on Well abandonment and inactive well practices, the last plug located in the Quaternary strata is compulsorily ensured, and the length of all plugs is also determined. Finally, the paper summarizes the methodology and presents suggestions for the abandonment process of the Shenhua CCS project. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd.

The pressure and temperature of a target CO 2 storage reservoir can significantly affect the migration and relative permeability characteristics which can ultimately determine the carbon storage capacity and storage integrity of target formations. To understand these impacts, a CO 2 core-flooding experiment was conducted on a brine-saturated sandstone containing a single clay interlayer perpendicular to the flow direction at a temperature of 313 K and a pressure of 8 MPa and the fluid distribution was monitored by a high-resolution X-ray computed tomography (X-CT) scanner. Further, a one-dimensional model was established to reproduce the CO 2 flow behavior inside the sample under the same experimental condition and then the model was extended to different temperatures (313 and 350 K) and pressures (6,8,12, and 17.4 MPa). The experimental results show that the CO 2 preferentially created high-CO 2 -saturation flow pathways which then expanded until they were large enough to transport the CO 2 at the prescribed flow rate. The sub-core scale heterogeneity also had significant effects on the CO 2 migration, forming a barrier to downstream flow. The simulation results show that at a given temperature, the CO 2 front migration velocity decreased with increasing reservoir pressure while the CO 2 saturation along the pathways increased. Comparing simulations when the reservoir pressure was the same, the front-migration velocity increased with increasing temperature, and the CO 2 saturation along the pathways decreased. Meanwhile, the influence of temperature and pressure on CO 2 saturation distribution was more evident in the parts of the core with high residual brine saturation.
