Pak Rus Secara fisik dan mineralogi apakah perbedaan anatar deep sea shale dengan hale yang dosebutkan yg doiendapkan pada semi arid /sabhka/ restricted env ? Apa pengaruhnya untuk kandungan gas methane ?

Sweetspot organic rich shale bercampur authigenic/evaporite mineral spt dolomite, anhydrite dll (CMIIW). Kondisi dep env. yang mendukung brittleness dan fractability dari shale gas tsb. Sukses story untuk Mezosoic(Jurassic Pre-Rift) juga belum terdengar.. Sekedar meramaikan diskusi Pak.

Wah kalau abu-abu isotropic dong, sedikit organiknya dan ngak fracable. Mungkin lokasinya dipilih dari sweet spot seismic? Tapi seharusnya kan dilihat dahulu dari data sumur yang ada? apakah sweet spot itu mengambarkan zona resistivitas yang tinggi dan zona anisotropi dari shale. Kemungkinan yang lain adalah belum ada data sumur, jadi explorasi banget buat shale? Atau operatornya dari negara dengan kekuatan militer terbesar di dunia tapi ngak pernah menang perang...heee...heeee Salam Anggoro Dradjat On Sun, Jun 24, 2012 at 6:04 PM, nyoto - ke-el <ssoena...@gmail.com> wrote: Apakah itu berarti operatornya tertipu atau ditipu atau salah interpretasi sebelumnya sehingga mengexecute project tsb ?
