Peningkatan kebutuhan energi dan penurunan produksi pada lapangan minyak yang telah memasuki tahap mature mendorong pengembangan metode Chemical Enhanced Oil Recovery (Chemical EOR) untuk meningkatkan perolehan minyak. Penelitian ini bertujuan untuk menentukan Recovery Factor melalui pengujian spontaneous imbibition menggunakan kombinasi surfaktan nonionik dan amfoter dengan penambahan alkali S…
Most of the world's oil reserves, especially in Indonesia, are already in the mature stage. So, in overcoming this problem, Enhanced Oil Recovery (EOR) is needed to increase oil production from mature reservoirs. The Alkaline Surfactant Polymer (ASP) flooding combination process is carried out by injecting chemicals gradually to increase displacement efficiency and expand sweep efficiency. …
