“…In traditional coal mining, CBM is considered a type of hazardous gas, not only because of the danger of explosions and gas outbursts, but also because of serious threat to the safety of mine production [1][2][3][4][5][6]. In contrast, CH4, the main ingredient of CBM, is a greenhouse gas, whose greenhouse effect is ~21-23 times as strong as that of CO2 [7][8][9][10]. However, the amount of gas emissions to the atmosphere because of coal mining is ~19.4 billion m 3 per year in China, resulting in both the waste of resources and environmental pollution [11].…”

Abstract:The Yangquan coalfield is one of the typical highly gassy mining areas in China. However, its coal seams are of lower permeability, which are not conductive to coalbed methane (CBM) drainage. In this study, based on the theory of the ground movement, we analyzed the principle of coal and CBM coextraction in the Yangquan coalfield, and established the technology system of coal and CBM coextraction which was further implemented in the coal and CBM coextraction in the Yangquan coalfield. The coal and CBM coextraction technologies based on the "pressure-relief and permeability-increase" effect caused by the mining overburden movement can optimally ensure the safe and efficient mining and improve the gas drainage rate. A series of developed coal and CBM coextraction technologies for the Yangquan coalfield were mainly characterized by the high-level gas drainage roadway. This reached a maximum gas drainage amount of 270,000 m 3 /day for single drainage roadway and a pressure-relief gas drainage rate of >90%. Those technologies significantly improved the gas drainage effect safely and efficiently achieving the coal and CBM coextraction. OPEN ACCESSEnergies 2015, 8 6882

“…Further, in many practical applications model calibration is achieved through a sequential series of processes and informed estimates which are difficult to emulate in a single optimization process. The literature for CO 2 sequestration contains many examples of history matching of monitoring data for model calibration . However, few of the published cases provide details of the history matching method used.…”

Injecting carbon dioxide (CO2) into the subsurface comes with the added responsibility of understanding the movement of the CO2 once injected, and ensuring that it remains contained in the target reservoir. Consequently, a significant part of the sequestration process is to build and maintain models of the subsurface that will predict the flow of the injected CO2. These models need to integrate all data available so that the subsurface movement of the CO2 can be predicted should changes to the injection parameters be made. As the CO2 plume is monitored by various measurements, the model needs to be flexible enough to be updated to account for any difference between predicted and known behavior. An integrated predictive reservoir model was created for the Illinois Basin – Decatur Project utilizing a variety of data collected from 2007 until January 2013. The evolution of this model will be discussed. Prior to the beginning of injection, in November 2011, reservoir models and numerical simulations were used extensively to design the wellbore, completions, and well tests; optimize predicted injectivity; simulate the CO2 subsurface migration development and pressure perturbation; analyze and understand well test results; and quantify uncertainties in predictions. Now, with the help of dynamic injection data collected, the calibration of the model has been accomplished by honoring the observations and this facilitates making more informed forecasts. Our analysis indicates a laterally developing CO2 subsurface migration, thus reducing the near to mid‐term expectation of CO2 reaching the seal and upper sections of target reservoir. Further planned modeling efforts include additional model refinements required for anticipated future applications including regulatory compliance and multi‐physics data integration.
