  • Coal Bed Methane - A Global Market Scenario

    Coal Bed Methane (CBM) is a type of natural gas that is commonly extracted from coal beds located at depths between 300 to 1000 metres. This gas is an odorless, colorless mixture of a variety of gases, but with major share of methane – even upto 95% in many cases.  Browse: Coal Bed Methane ...


  • Recovering coal bed methane from deep unmineable coal seams and carbon sequestration

    Published data from nearly 2,000 coal samples comprising 250 coal beds from 17 states, representing many of the coal producing horizons in the USA, shows moderate correlation (0.7) between depth and methane content for high volatile coal ranks. Low-volatile rank coals average the highest methane content, 12.74 m?/ton (450 ft?/ton), subbituminous rank coals the lowest, ...

  • Treatment of coal bed methane produced water using short bed ion exchange

    Abstract: The water produced during the recovery of natural gas from coal beds, coal bed methane - CBM, is often a major problem in developing this resource. A pilot study of a short bed ion exchange process treating CBM produced water is presented. The paper will discuss background issues related to CBM produced water, alternate treatment methods, short bed technology, pilot plant test data, and ...

  • Proppant flowback control in coal bed methane wells: experimental study and field application

    Proppant flowback after fracturing coal bed methane (CBM) wells is a very common challenge which results in fracture pinching out, noticeable well productivity decrease, downhole and surface facility damage, etc. In this paper, fibre was studied as a low-cost and environmentally friendly additive to control proppant flowback in CBM well fracturing operation. Two kinds of glass fibre (short fibre ...

    Global CBM (Coal Bed Methane) market is expected to reach USD 17.31 billion by 2020, growing at a CAGR of 5.9% from 2014 to 2020. Unconventional CBM reserves, especially in coal-rich regions are increasingly gaining the spotlight as the industry strives for energy independence. Exploration and commercialization of unconventional hydrocarbon energy sources is seen as a critical step by energy ...


  • Exploratory study of some potential environmental impacts of CO2 sequestration in unmineable coal seams

    An initial investigation into the potential environmental impacts of CO2 sequestration in unmineable coal seams has been conducted, focusing on changes in the produced water during enhanced coalbed methane (ECBM) production, using a CO2 injection process (CO2-ECBM). A high volatile bituminous coal, Pittsburgh No. 8, was reacted with synthetic produced water and gaseous carbon dioxide at 40C and ...

  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...
