“…However, the tri-axial experiments in this work were under hydrostatic conditions with a uniform confining pressure that was held constant and with the sample able to undergo tri-axial strain. As with Connell et al (2011), the hydrostatic permeability model of Connell et al (2010) was used in SIMED II to represent these experimental conditions. The model differentiates between bulk and pore sorption strains due to gas desorption and is written as:…”

“…In the simulations the permeability variation with swelling/shrinkage was described by a Sawyer et al (1990) based model. This current paper extends the work of Connell et al (2011) to CO 2 ECBM, applying the same methodology of core flooding combined with history matching using a reservoir simulator, but with CO 2 displacement as the focus. CO 2 is a high adsorbing gas for coal and represents a significantly different displacement process compared with the low adsorbing nitrogen dominated enhanced recovery experiments presented in Connell et al (2011).…”

Connell et al (2011) present a series of ECBM core flooding experiments where N 2 and an artificial flue gas mixture (90%N 2 :10%CO 2 ) were used to displace adsorbed methane from coal. The results from these core flooding experiments were used in history matching to test the reservoir simulation of these processes.…”

Coal seams, particularly deep unmineable coal reservoirs, are the most important geological desirable formations to store CO 2 for mitigating the emissions of greenhouse gas. An advantage of this process is that a huge quantity of CO 2 can be sequestrated and stored at relatively low pressure, which will reduce the amount of storage cost required for creating additional platform to store it. The study on CO 2 storage in coal seam to enhance coal bed methane (ECBM) recovery has drawn a lot of attention for its worldwide suitability and acceptability and has been conducted since two decades in many coalmines. This article focuses on the coal seam properties related to CO 2 adsorption/desorption, coal swelling/shrinkage, diffusion, porosity and permeability changes, thermodynamic/thermochemical process, flue gas injection, etc. Here, the performance analysis of both CO 2 storage and ECBM recovery process in coal matrixes is investigated based on the numerical simulation. In this study, a one-dimensional mathematical model of defining mass balances is used to interpret the gas flow and the gas sorption and describe a geomechanical relationship for determining the porosity and the permeability alteration at the time of gas injection. Vital insights are inspected by considering the relevant gas flow dynamics during the displacement and the influences of coal swelling and shrinkage on the ECBM operation. In particular, pure CO 2 causes more displacement that is more efficient in terms of total CH 4 recovery, whereas the addition of N 2 to the mixture assists to make quicker way of the initial methane recovery. However, this study will support future research aspirants working on the same topic by providing a clear conception and limitation about this study.
