Since then, CBM has become one of the leading professional organizations for people with disabilities worldwide.Currently, CBM supports all over 1000 meets in over 100 countries. CBMs vision is of an inclusive world in which all persons with disabilities enjoy their gentlemans gentleman rights and achieve their full potential. 1. 2 ORIGIN OF METHANE Coal bed methane evolves during the renewing of the organic matter in the swamp, which later converts into peat after burial under reducing condition. As tempe rature out harvestings the peat converts into lignite followed by sub-bituminous, bituminous low- fickle medium volatile, high volatile anthracite and graphite.This process is known as blackenification. During this process at early stage biogenic methane evolves, later thermogenic methane is formed. Much of the methane generated by the coalification process escapes to the surface or migrates into adjacent reservoir or other rocks, only if a portion is trapped within the coal itself. In early stages of coalification, biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the ready remains and surrounding sediments.In fresh water environments, methane ware demoralizes immediately after the oxygen is depleted. Species of anaerobic bacteria (those that dont use oxygen) then cut down carbon dioxide and produce methane through anaerobic respiration. When a coals tempera ture underground reaches nearly122F and after a sufficient amount of time, most of the biogenic methane has been generated, and about two-thirds of the original moisture has been expelled, the coal attains an approximate rank of sub-bituminous.As the temperature increases above 122F through increased burial or increased geothermal gradient, thermogenic processes begin and additional water, carbon dioxide, and nitrogen are generated as coalification proceeds to approximately the rank of high-volatile bituminous. Maximum genesis of carbon dioxide, with little methane generation occurs at about 210F. Generation of thermogenic methane begins in the higher ranks of the high volatile bituminous coals, and at about 250F, generation of methane exceeds generation of carbon dioxide. Maximum generation of methane from coal occurs at about 300F.With even higher temperatures and higher rank coals, methane is still generated, but at somewhat lower volumes. Primarily adsorbed on or absorbed wi thin micro pores of the coal. Coal bed methane is found associated with the coal/ lignite beds. This is the product that evolves during the process of coalification generally more in quantity than the coal cigaret hold. Some of the splash escapes in the surroundings but some of it lie in the coal under hydraulic pressure. Coal is unique in its deportment as it acts as a source as salubrious as a reservoir rock. Generally the gas content increases with rank. 2. CBM IN INDIA, AN OVERVIEW India is potentially fecund in CBM. The major coal sphere of influences and CBM blocks in Indian are shown in Fig. The directorate General of Hydrocarbons of India estimates that deposits in major coal fields (in 12 states of India covering an land of 35,400 km2) contain approximately 4. 6 TCM of CBM. Coal in these basins ranges from high volatile to low-volatile bituminous with high ash content (10 to 40 percent), and its gas content is amid 3-16 m3/ton depending on the rank of the coal, de pth of burial, and geotectonic settings of the basins as estimated by the CMPDI.In the Jharia Coalfield which is considered to be the most prospective area, the gas content is estimated to be between 7. 3 and 23. 8 m3 per ton of coal within the depth range of 150m to 1200 m. Analysis indicates every 100-m increase in depth is associated with a 1. 3 m3 increase of methane content. In India, commercializedized CBM production is notwithstanding to be started in full pace. Few EP companies like ONGC Ltd. , GEECL and Essar Oil have started production, but field festering is yet to be completed.India ranks 134th out of 182 countries, the same as in 2006, in the 2009 Human Development Report and is home to 60-80 million people with disabilities (PWDs). CBM regional office for the atomic number 16 Asia Region has prioritised implementation of programs in states which have high percentages of people below the poverty line and high number of people with disabilities. CBM started to cove r its support to India in 1967 and in 1975 the South Asia regional Office was established in Trichy, Tamil Nadu to coordinate activities in India, Nepal, Bangladesh and Sri Lanka.In 1994, the Regional Offices in North and South were established to cater to the senesceing projects supported by CBM. 2. 1 INDIAS ENERGY SCENARIO * India is one of the fastest growing economies. * The GDP growth is over 8%, likely to increase to over 10% in near future. * This GDP growth is required to eradicate poverty and meet countrys human development goal. * To sustain such growth 3/4 fold increase in primary energy requirement envisaged. * Integrated Energy Policy Document indicates total energy requirement of the country will increase from a current level of about 500 MTOe to 2000 MTOe by 2031-32. Efforts are on to utilize all possible energy resource- renewable, non-renewable, coal based additional resource etc to meet this gigantic target. 2. 2 CBM ACTIVITIES IN INDIA 1967 CBM extends support to India and the first Regional Office of CBM was opened in Trichy in 1975 for India, Bangladesh, Nepal and Sri Lanka. 1975 The comprehensive ophthalmic health program for Thiruchirapalli was started in Joseph Eye Hospital. Community ophthalmology was born 1977 The first Community establish Rehabilitation (CBR) project at Musiri started with single disability. 1979Concept of integrated education was promoted by CBM. CBM has been included as a member of the Committee of the Rehabilitation Council of India dealing with optical Impairment. 1999 Together with other NGOs and WHO, CBM initiates VISION 2020 The Right to Sight, a global initiative for the elimination of avoidable blindness by the year 2020. 2004 CBM awarded by the Indian Govt. in appreciation of exemplary contribution towards elimination of Avoidable Blindness in India. 2006 CBM with other NGOs initiated programmed of Sound Hearing 2030. WHO SEARO has been supporting this initiative. . 3 DEVELOPMENT OF CBM IN INDIA Commercial production of CBM started and during 2008-09 it was 0. 15 MMSCMD (million Std cubic meter per day). The CBM production is expected to increase to 3. 6 MMSCMD by 2011-12 and to 7. 14 by 2014 2. 4 CBM STATISTICS IN INDIA * CBM pick 3. 4 TCM (CMPDI Estimate 2008) * 26 Blocks allotted for Commercial Development * Production potential 38 Million Cubic cadencys per day, which can support power generation of 6700 MW. * Commercial production of CBM started and was 0. 15 million cubic meters per day. * Expected to rise to 3. million cubic meters per day in 2011-12, showing 24 fold growth in 2 years. * Allotment of 8 more blocks under consideration of the Govt. 3. 0 CBM RESERVES Indian STATUS 3. 1 CBM RESERVES IN INDIA SNo. realm Coal Fields/Block Area (Sq.

Fig-Hydro-Fractured Unit of 3rd puff up 4. 2 CURRENT PROJECT ON CBM IN INDIA Great Eastern Energy Corporation Ltd (GEECL) hasbegunthe production and sale of coal-bed methane (CBM), the first such commercial project in India. GEECL is targeting initial production of 1. 5 million standard cubic feet per day (MMSCFD) estimated in- office staff gas in the block is 1. 92 trillion cubic feet (TCF) per Netherland, gallant and Associates, Inc. (NSAI) on 1 June 2007. * As of June 2007, GEECL had drilled, perforated and fractured 23 wells and installed the pumps. Nine wells are currently in production, delivering 991 thousand cubic feet (MSCFD) per day, along with 8,030 place of product watera current water-gas ratio of 8. barrels of water per MCF of gas. Over time, the water ratio decreases and gas production increases as the beds are dewatered. * Indias Directorate General of H ydrocarbons (DGH) has approved investing $150 million for drilling 100 production wells in four years. * Reliance Industries (RIL) and Oil and essential Gas Corporation (ONGC), the countrys two biggest exploration and production companies of conventional oil and gas, have also begun recovering some gas from coal beds. RIL has estimated in-place gas militia of 3. 5 TCF, and ONGC has reserves of around 1. 2 TCF. * RIL is likely to start commercial production by the end of 2007 ONGC is planning commercial production in 2008. 5. 0 CBM MARKET IN INDIA * The present scenario of rapidly increasing demand of CBM is highly encouraging for the year 2006-2007 the demand was of 231 MMSCMD and supply was 95MMSCMD and expected to grow from 168 MMSCMD supply demand was 313 MMSCMD in the year 2011-12 and in the year 2024-25 supply would be 170 MMSCMD while demand is expected to grow up to 391 MMSCMD. Directorate of Hydrocarbons recently took new areas for CBM exploration activities in CBM-III BID DING. Based on the characteristic properties viz occurrence of thick coal seams at favorable depth, high seam density, candid thermal maturity, favorable permeability, good gas content, sizeable coal reserves. * Recently, Govt. of India further announced 10 blocks in order to explore and produce (CBM). Out of these, two blocks each are located in the States of Andhra Pradesh, Chhattisgarh, Madhya Pradesh and Rajasthan and one block each in Jharkhand and West Bengal (MOP NG, 2006). For CBM contribution of 1% of total energy output, 1 well per 60 acre, the development area would be approx 360,000 acres, i. e. 1,450 sq km Exploratory Block area will be still larger. Approx 8,000 sq km of the coal bearing area is still unexplored for CBM. 5. 1 COST BENEFIT epitome IS PLACED BASED ON FOLLOWING ASSUMPTIONS Assumptions Parameter Unit Details Well productiveness SCM/Day 3500 Well Capital Cost 1.

Other West Bengali regularize vehicle demand could tally an additional 10 MMSCFD. Vehicle demand in neighboring Jamshedpur (200 km away) could reach 18 MMSCFD, according to the company. In India, commercial CBM production is yet to be started in full pace. Few EP companies like ONGC Ltd. , GEECL and Essar Oil have started production, but field development is yet to be completed. Steel, Glass, Ceramics and Paper manufacturing companies are showing keen interest to put up their plants in the region.The possible industries that can use CBM may be * Fertilizers, chemicals petrochemicals * townspeople Gas Industrial fuel supply * Power generation * Cement * Paper and paper products * Sponge iron steel * Ceramics * Glass * Textiles 8. 1 CHALLENGES IN IMPLEMENTATION * CBM Resource Assessment technique in de-stressed coal seams. * Techno-economic evaluation of identified CMM Project area. * Utilization technology of recovered methane. * Capture and Utilization technique of low concentration of methane in ventilation air. 8. 2 PROSPECT OF CBM IN INDIA To increase the pace of exploration and development of CBM the Government of India under CBM-III round of international bidding has identified 7 additional blocks in different coalfields, located in the States of Madhya Pradesh, Chattisgarh, Jharkhand,West Bengal, Andhra Pradesh Rajasthan and hold sizable resources of CBM showing good prospectivity. 8. 3 OPPORTUNITIES OF CBM IN INDIA The CBM terms offered by Government are definitely the very best in the world- * Seven years tax holiday from the date of commencement of production. * Fiscal stability provision in the contract. * No participating interest of the Government. No signature bonus. * No custom duty on imports required for CBM operations. * Freedom to sell gas in the domestic market at market determined rate. * During the last 3 years more than 75 exploratory / pilot wells have been drilled in the 16 CBM blocks awarded during the last two rounds of international bidding. * Significant finds reported in Jharia, Raniganj, Bokaro Sohagpur Coalfields in the Eastern and Central part of India * testing production of CBM in these blocks have yielded encouraging quantities of gas and commercial exploitation of Coalbed Methane (CBM) in India is no longer a myth but a reality. . 4 AWARENESS ABOUT CBM * Promotional Road Shows to be organized in January / February 2006 at USA, Canada, Australia, Russia, UK and India. * All the road shows to be presided over by the Honble Minister of oil color Natural Gas, besides the senior officials of the Ministry of Petroleum Natural Gas, Ministry of Coal and Directorate General of Hydrocarbons, Government of India. * A brochure giving details on the blocks on offer, the Geographical Location on a map of India, the Terms Conditions, Bid Format, a copy of the Modal CBM Contract and Price List will be made available free of cost. The Hard Copies Digital Copies (on work stations) of the Basin Information Dockets and Data Packages will be made available for inspection at data viewing centers in India and abroad. 9. 0 CONCLUDING REMARKS * Commercial exploitation of Coal Bed Methane (CBM) in India is no longer a myth but a reality. * The CBM gas flared in the test wells in Raniganj, Jharia and Sohagpur Coalfields in the eastern and central part of India bear ample testimony to the stories of success in the formative stage of CBM operation. India endowed with large resources base of coal and lignite contains sizable quantities of CBM gas. Initial test production in CBM fields of India shows encouraging results. * India has take a time bound aggressive dodge for exploration and development of CBM. * CBM an unconventional alternative source of natural gas has good future prospects in India. * CBM technology is proceeding with good space to prove itself as a cleaner energy security to India as well as the World. However, production strategy of methane from CBM is very much different from conventional gas reservoir.The study revealed that the coal type, rank, volatile matter and fixed carbon are strongly influence the surface assimilation capacity of methane into the coal bed. With increasing depth maturation of coal increases and generation of methane gas also increases. Gondwana basin as the most prospective CBM field is being developed now. From the studies, it is observed that Singareni coal field under Gandowana basin contains low gas Hence, presently it is not considered for CBM exctraction. However, in future this field may be considered for methane extraction using advanced technology and in emergency condition.Sequestration of CO2 helps in mitigation of global warming, at the same time helps in recuperation of methane gas from coal bed unveiled otherwise. However, detailed and intensive studies are required for efficient and economic production of coal bed methane. India with 4. 6 TCM of methane reserves in coal bed can enrich its per capita energy demand by successful exploitation of CBM. 10. 0 BIBLIOGRAPHY (Internet Based Methodology Only) 1. Singh, A. K.
