2. ➢CBM (Coal Bed Methane)
CBM is a hydrocarbon gas that is chiefly
composed of CH4 and is generated and stored in
coal beds in the adsorbed state. In coal mining, it
is commonly referred to as “marsh gas.”
CBM can be obtained at shallower depths than
shale gas and conventional gas
CBM is mainly distributed at the grain surfaces of
coal as absorbed gas and also occurs in cleats
and fractures as free gas or gas dissolved in water.
As a general rule, the lower the coal rank, the
more free gas in the coal bed, and the higher the
coal rank, the more adsorbed gas in the coal bed.

3. 1. Drilling several well into the coal
seam at 300 – 1000 meter depth
2. Dewatering process occurred by
pumping out water and lowering the
pressure
3. The water removal reduces the
pressure and allows the methane to
release from the coal to produce
flowing gas
4. Coal bed methane contaminants
(CO2, Nitrogen) removed at the
separating unit before further uses at
the GCU and Power Station

9. ▪ SKK Migas supports the development of CMB by
holding 3 FGD events in 2018
▪ SKK Migas has placed non-conventional oil and
gas projects in its long-term plan until 2030
▪ The Ministry of Energy and Mineral Resources
(ESDM) has confirmed the transfer of the
production sharing contract for the Tanjung Enim
Coal Bed Methane (CBM) Block from Cost
Recovery to a gross split

10. ▪ Implementation of unconventional oil and gas
studies in all active working areas to determine
the level of non-conventional oil and gas
potential. after knowing the potential, the
cooperation contract contractor (KKKS) can
directly carry out production drilling
▪ Implementation of non-conventional oil and gas
production pilot projects in potential work areas
using multi-stage fractured horizontal (MSFH)
technology
