PETROGRAFI ORGANIK DAN RETORTING CONTO BATUAN HASIL PEMBORAN SUMUR BH-02 ANGGOTA ATAS FORMASI TELISA UNTUK MENGETAHUI POTENSINYA SEBAGAI SERPIH MINYAK, DI DAERAH PADANGLAWAS, SUMATERA BARAT.
Abstract
Analisis petrografi organik conto batuan sedimen halus dari Sumur BH-02 daerah Padanglawas memperlihatkan kandungan material organik didominasi oleh kelompok liptinit, yaitu maseral lamalginit dan telalginit(botryococcus), sedangkan vitrinit dan inertinit hadir dengan jumlah sedikit. Kandungan TOC pada conto batuan berkisar 3,13-14,80%. Nilai Rv (reflektansi vitrinit) berkisar 0,200,30%, mengindikasikan material organik conto batuan dikategorikan belum matang. Berdasarkan analisis retorting yang dilakukan pada 89 conto batuan, diperoleh kandungan minyak pada conto batuan berkisar 2-78 liter/ton batuan atau dengan rata-rata sebesar 27 liter/ton batuan.Downloads
