Development of Coal Mine Methane in NLC’s Leasehold area. • In Neyveli basin total available reserves of Lignite for CBM development is 5500 MT. • Likely gas reserves is 8250 MCM. • Geological setup is similar to Powder River basin of USA • 2400 MT reserves are already in NLC’s leasehold. Additionally 1000 MT in Jayamkondam is applied for lease. • The above areas can be taken for immediate studies. 44
A study for CBM in NLC lease hold area can be advantageous for * The study can start immediately * If suitable, surrounding area can be added for resources. * Carbon sequestration can be possible in CBM voids - held in getting carbon credits. 45
