Mas Shofi, Yang produksi dari basement itu sejauh ini paling besar Suban yang basementnya granit. Nah, yang basementnya marble, kuarsit dan filit apakah ada yang di produksi? Nah, kalau filit kan lebih susah untuk "retak" ya, karena tidak segetas granit dan marble.
Kalau umur granitnya sama umur marbel, filit dan kuarsit, apakah sudah ada yang meneliti ya? (menyesal pas kuliah Pak Sartono ngga banyak nanya).

Vita, Sekedar berbagi cerita sedikit saja sewaktu bekerja untuk sumur sumur gas di Sumatra Selatan. Pada dasarnya, basement yang ditemui terdiri dari batuan beku (yang terbanyak tipe granitik sampai granodiorit) dan ada pula batuan metamorfik yang terdiri dari pilit, kuarsit sampai marble. Semuanya menghasilkan gas. Yang lain silahkan nambahin. 2013/9/25 Parvita Siregar <[email protected]<mailto:[email protected]>> Rekan-rekan IAGI-Net yang asik2, Ini mungkin pertanyaan yang tidak terlalu cerdas, tetapi saya kemarin2 ini melihat data beberapa sumur di Sumatra yang sampai ke basement. Dan dalam jarak yang lumayan dekat, komposisi basementnya beda sekali: yang satu marble, yang satu phyllite. Sementara, saya yang lumayan awam ini berpikiran kalau di Sumatra itu, basementnya mustinya granitic. Ternyata tidak musti begitu ya? Mungkin ada yang mau memberikan pencerahan mengenai basement? Sekali2 jadi Hardrockerlah...(hidup metaaal).
