Batas dasar ekonomi ketika itu kalau harga minyak mentah diatas $38.00/barel, maka pengolahan serpih minyak bisa ekonomis. Kemudian harga minyak jatuh sekitar tahun 1985-1986, beratus-beratus geologiawan di-PHK-kan (termasuk kula niki!). =================================== Lha sekarang harga minyaksudah 70 an $ ,berarti beratus ratus geologiawan dicari dong pak. saya masih ingat awal tahun 90 an dulu waktu temen temen melakukan penelitian batubara cair mengatakan akan ekonomis kalu harga minyak 35 $, ternyata sampai sekarang juga tetep saja tdk ada yang mengusahakan., begitu juga dg berbagai energi alternatif lainnya. Bagaimana dg CBM apa juga tetep belum ekonomis . Mungkin nanti barangkali kalau minyak betul betul habis ,baru yang lain di cari cari ( ibaratnya gresek gresek sing ono )

Ada yang mengusulkan sebagai bahan baku bata. Ingatlah bahwa proses untuk memeras minyak dari serpih minyak yalah dengan proses "pyrolisis" atau "retorting" dengan memanaskan serpih minyak dan pencegahan oksidasi dari hidrokarbon-nya. Perubahan mineral lempung dll karena suhu yang tinggi juda akan merupakah persoalan pembuangan sampah serpih minyak. > > Seperti rekan-rekan ketahui serpih minyak adalah suatu batuansumber (source rock) yang kedewasaannya rendah (low maturity), tetapi juga serpih minyak yang kedewasaanya sangat tinggi (misalnya serpih hitam Chattanooga di Kentucky, Tennessee, dsb. dengan umur Paleozoik). Topik dissertasi saya ketika itu adalah serpih hitam dari Prekambrium di Australia Selatan (jadinya sangat tua, walaupun melalui proses pirolisis, minyaknya masih bisa diperas dalam skala laboratorium). > > Sepertinya analogi dengan orang, serpih minyak bisa anak muda (bahkan balita) atau orang yang sangat tua. > > Barangkali ada rekan-rekan geologiawan yang ingin mulai suatu diskusi tentang serpih minyak? > > salam, > > Yo Sumartojo > Marietta, Georgia, A.S. > > > From: [EMAIL PROTECTED] > > Date: 2006/07/12 Wed PM 10:55:46 EDT > > To: iagi-net@iagi.or.id > > Subject: Re: [iagi-net-l] Oil Shale (The next Saudi Arabia?) > > > > > > > Rekan > > > > Seingat saya beberapa puluh tahun lalu (more than 15 tahun) , pernah > > jadi trend .
