Social Issue Related to Well Completion

Postoleh rosmalia » Sab Apr 21, 2012 4:56 pm

Dear friends,

Discuss yuk,
Seperti kita ketahui bahwa produksi minyak dan gas bumi secara conventional sudah menurun, sehingga kita mulai beralih ke unconventional features (such as CBM, tight gas sand, fractured basement and shale gas). Produksi untuk CBM sepertinya di Indonesia sedang dilakukan dengan dewatering sedangkan yang lainnya baru dilakukan preliminary study. Well completion pada shale gas dan tight gas sand menggunakan teknik hydraulic fracturing dengan desain horizontal well drilling, namun teknik ini sebenarnya tak mudah dilakukan karena harus flushing fresh water yg mencapai 90% disertai acid fluid dan propant ladden fluid untuk menjaga rekahan agar tetap menganga. Penggunaan fresh water yg sebenarnya juga menjadi sumber kebutuhan hidup kita (untuk minum terutama) menjadi social issue yg harus diperhatikan dalam memproduksi gas dari teknik ini. Apalagi dari meeting dengan beberapa company yg sedang study unconventional reservoir ini membidik kawasan Indonesia bagian timur sebagai tempat eksplorasi. Jika potensi kedua unconventional method tersebut diketahui ada, namun sumber daya air di Indonesia bag timur tidak mencukupi untuk dapat memproduksi shale gas/ tight gas sand lantas saran apakah yang bisa disajikan (selain membidik renewable energy ya)? Saya sempat terpikir untuk menyelesaikan masalah penggunaan fresh water untuk hydraulic fracturing dengan teknik desalinasi (mengubah air laut menjadi air tawar) seperti yg dilakukan Australia untuk penduduk Aceh saat tsunami berlangsung. Kira2 apakah metode ini tepat untuk diterapkan ataukah ada ide2 lain? Saran dan diskusi are very welcome...
