Pak Rus,

Untuk referensi karakterisasi reservoir termasuk proses diagenesis di shale gas 
dapat dilihat di SPE 131350 oleh Passey dan Bohacs, 2010: "From Oil-Prone 
Source Rock to Gas Producing Shale Reservoir - Geologic and Petrophysical 
Characterization of Unconventional Shale Gas Reservoirs".

Untuk lebih banyak informasi bisa dicari "illitization on shale gas".

Selama 3 tahun belakangan ini kami mengamati banyak data petrologi dan 
mineralogi batuan serpih syn-rift, sayangnya belum bisa dipublikasikan.

Salam,
Wikan
