 History of CBM
 Indonesia CBM Potential
 Produksi CBM & Teknologi Pengeboran
 Benefits of CBM as Gas Potential Energy
Out Line
Coal is formed from
biomass that has decayed,
been compacted,
hardened, chemically
altered and
metamorphosed by heat
and pressure over
geologic time
COALIFICATION

and Durucan 2003)

BACKnamun.. Perlu kita tahu
Kondisi inilah yang menyebabkan
permukaan batubara menjadi sedemikian
luas sehingga mampu menyerap gas dalam
jumlah yang besar (kemampuan
mengadsorpsi gas)

batubara terbesar di dunia.
Sebarapa Prospek Cadangan Kita ?
Cadangan Coal Bed Methane (CBM)
Indonesia saat ini cukup besar, yakni
450 TCS dan tersebar dalam 11 basin.
Potensi terbesar terletak di kawasan
Barito, Kalimantan Timur yakni sekira
101,6 TCS, disusul oleh Kutai sekira
80,4 TCS. Bandingkan dengan gambar
8, Amerika yang memiliki cadangan
batubara cukup luas dan tersebar,
hanya memiliki cadangan CBM yang
relatif kecil.
Berdasarkan data Bank Dunia,
konsentrasi potensi terbesar terletak di
Kalimantan dan Sumatera.
COALBED METHANE (CBM)
PRODUCTION and DRILLING
GOOD PERMEABILITY
Teknik ini memungkinkan produksi gas dapat ditingkatkan volumenya
melalui satu lubang bor. dengan menggunakan teknik ini JUGA
MEMUNGKINKAN Produksi gas secara ekonomis pada suatu lokasi yang
selama ini tidak dapat diusahakan, terkait permeabilitas lapisan batubaranya
yang jelek. Sebagai contoh adalah apa yang dilakukan di Australia dan beberapa
negara lain, dimana produksi gas yang efisien dilakukan dengan sistem produksi
yang mengkombinasikan sumur vertikal dan horizontal, seperti terlihat pada
gambar di ATAS.

MANFAAT CBM DALAM KETERSEDIAAN ENERGI
Eksploitasi CBM tidak akan merubah kualitas matrik batubara dan
menguntungkan para penambang batubara, karena gas emisinya telah
dimanfaatkan sehingga lapisan betubara tersebut menjadi aman untuk di
tambang, selain itu CBM ini termasuk salah satu sumber energi yang ramah
lingkungan.
