    The body of the main report (i.e., “Conceptual Design for a Coal Mine Gob Well Flare”) specifies gas flows ranging from a low of 20 thousand scf per day (mscfd) to a high of 2 million scf per day (mmscfd) (14 to 1,400 scfm). Further, it is most likely that at the high gas flows high concentrations of methane (up to 100%) could be expected, but at the lower gas flow rates the methane

  • Raven Ridge Resources Incorporated | Modeling Methane

    The gob permeability, and hence the PI, should be adjusted to match actual well performance once a gob well is activated. This will provide a more reliable forecast of gob well production and in-mine emissions. The effect of setting a blower to apply a vacuum at the wellhead is simulated by setting the value of Pwell, or bottom-hole pressure, at the value corresponding to the designed suction

  • Enhanced Gob Gas Recovery EPA

    Gob well completion concerns include vertical placement of the well within the gob, maintaining well integrity and productivity after undermining, and isolating water-bearing horizons. Water-bearing strata must be isolated from the well and mine workings by proper well-casing cementation practices. In some cases, significant water inflow is unavoidable and may worsen after mining because of
