“…and Liu et al (2005Liu et al ( , 2006 estimated the CO 2 storage capacity in deep saline formations, coalbeds, and gas fields in China to be 1.43505×10 11 t, 1.2078×10 10 t, and 4.103×10 9 t, respectively. Yu et al (2007) estimated that in China's coalbeds the CO 2 storage capacity is about 1.4267×10 11 t. The main contributes of CO 2 sequestration in coalbed methane (CBM) zone are Qinghai, Eastern Ordos and Eastern Yunnan-Western Guizhou. Meng et al (2007) estimated the economical availability of CO 2 storage demonstration projects in China.…”

The geological storage of CO 2 in deep saline formations is increasing seen as a viable strategy to reduce the release of greenhouse gases to the atmosphere. There are numerous sedimentary basins in China, in which a number of suitable CO 2 geologic reservoirs are potentially available. To identify the multi-phase processes, geochemical changes and mineral alteration, and CO 2 trapping mechanisms after CO 2 injection, reactive geochemical transport simulations using a simple 2D model were performed. Mineralogical composition and water chemistry from a deep saline formation of Songliao Basin were used. Results indicate that different storage forms of CO 2 vary with time. In the CO 2 injection period, a large amount of CO 2 remains as a free supercritical phase (gas trapping), and the amount dissolved in the formation water (solubility trapping) gradually increases. Later, gas trapping decreases, solubility trapping increases significantly due to migration and diffusion of the CO 2 plume, and the amount trapped by carbonate minerals increases gradually with time. The residual CO 2 gas keeps dissolving into groundwater and precipitating carbonate minerals. For the Songliao Basin sandstone, variations in the reaction rate and abundance of chlorite, and plagioclase composition affect significantly the estimates of mineral alteration and CO 2 storage in different trapping mechanisms. The effect of vertical permeability and residual gas saturation on the 2 overall storage is smaller compared to the geochemical factors. However, they can affect the spatial distribution of the injected CO 2 in the formations. The CO 2 mineral trapping capacity could be in the order of ten kilogram per cubic meter medium for the Songliao Basin sandstone, and may be higher depending on the composition of primary aluminosilicate minerals especially the content of Ca, Mg, and Fe.

“…It is further concluded that the research and development in India should be more focused on CBM for commercialization. Yu et al [6] studied the CBM and ECBM potential of China and estimated 142.67 Gt of CO 2 sequestration potential in existing coal beds. Vishal et al [7] developed a CBM model to assess the viability of ECBM in Indian coals.…”

“…However, coalbed methane can also result in great disasters in coal mines [1][2][3][4][5], so the coal seam gas exploitation is imperative. China has a large reserve of coalbed methane, but it is difficult to exploit because the permeability of coal reservoir is very low [6]. Therefore, increasing the desorption rate and permeability of coals are important to improve the extraction rate of coalbed methane.…”
