India is among the top five countries in the world in terms of proven coal reserves and coal production. As such, significant potential exists for commercial recovery of coalbed methane (CBM). Two coalfields, Jharia and Raniganj, located in eastern India are currently under development for CBM. This paper describes work done to determine coal seam properties, ambient stress conditions, and effects of depletion at these coalfields that influence CBM production. Coalbed permeability is a parameter that has a major influence on CBM production. Other influences include in-situ stress direction, gas content, and the application of suitable stimulation techniques. A robust methodology is required to determine both initial coalbed permeability and its relation to in-situ horizontal stress magnitudes. Coalbed permeability at the Jharia and Raniganj coalfields was estimated from porosity and known cleat spacing. Initial permeability of major coalbeds was correlated with effective horizontal stress, yielding satisfactory to very good exponential fit using data from Raniganj and Jharia wells. Acoustic televiewer image-logging tool measurements in a single well in the Jharia coalfield were used to infer a maximum horizontal stress orientation between N25°W and N25°E. Reservoir-pressure-dependent permeability models are presented for coalbeds under uniaxial strain condition. The coalbed permeability is dominated by the existing effective horizontal stresses normal to the cleats. Two prospective coal seams from Jharia have been identified through assessment of the response of horizontal stress to the decline of CBM reservoir pressure. Coalbed permeability increases with the drawdown of reservoir pressure and is exponentially related to the change of effective horizontal stress during reservoir depletion. The results of this study are to be used for production history matching for wells in Jharia and to determine optimal horizontal drilling directions for increased CBM production.

Conventional well logs from three wells in South Karanpura coalfield are analyzed to correlate 10 major coal seams belonging to the Barakar formation for coalbed methane (CBM) exploration. Face cleat orientations are studied for the Simana and Argada coal seams from the Sirka and Argada mines. It varies from 130 to 140°N for a total 349 face cleats observed from Simana and Argada coal seams. Cleat identification and its orientation have also been analyzed from simultaneous acoustic and resistivity (STAR) log from two CBM wells located 20–22 km away from the Sirka and Argada mines. Total number of fractures is found to be 1118 from two wells. Face cleats are not distinguishable from STAR image. Fracture density in coal is varying from 2.48 fractures per meter to 23.8 fractures per meter with a maximum density in the Banasgarah seam. Fracture orientations observed in Saunda, Sayal, Balkudra, Kurse, Hathidari, Banasgarah, and Argada vary from 10°N to 115°N. The in situ maximum horizontal stress (SH) is compu...

CO2-ECBM sequestration in Jharia CBM field is proven to be explicitly significant project in mitigating the rising atmospheric GHGs especially CO2 not only as a potential geological storage in coal matrix also enhancing CH4 production leading to improved gas recovery factor, thereby generating revenue that offsets the expense of sequestration. Modeling of Jharia coalbed for CO2-ECBM sequestration is carried out after analyzing the reservoir complexity. In this modeling, reservoir simulator COMET3 was used to develop a numerical model to simulate the field conditions using data for Jharia coal seam. The production characteristics of the reservoir were made to coincide with the current rate of methane production from coal blocks in this area and the same established model was substituted for injection of CO2 over 2000 days to enhance the production of methane. Numerical simulation results using five-spot pattern well orientation at coal seam have shown an increase of CH4 production by 215% than the usual production by CO2 sequestration. Additionally, CO2 was stored at the maximum injection rate. It is been observed that approximately 204 Mm3 of CO2 can be sequestrated in the area of 56 Mm3 of CH4 produced from the chosen dimensions of coal grid block.
