Abstract

Pengembangan teknologi proses produksi surfaktan MES (Metil Ester Sulfonat) dari minyak sawit untuk aplikasi EOR/IOR pada lapangan ASL telah dilakukan sebelumnya melalui penelitian secara terus menerus dan berkesinambungan. Studi laboratorium recovery minyak dilakukan dalam 6 metode penginjeksian yaitu dengan Surfaktan (0.3%) + Polimer P1 (0.2%), Surfaktan (0.3%) + Polimer P2 (0.2%), Surfaktan (0.3%) Polimer P1 (0.15%) + Polimer P1 (0.2%), Surfaktan (0.3%) Polimer P2 (0.15%) + Polimer P2 (0.2%), Surfaktan (0.3%) + Surfaktan (0.3%) Polimer P1 (0.15%) + Polimer P1 (0.2%), Surfaktan (0.3%) + Surfaktan (0.3%) Polimer P2 (0.15%) + Polimer P2 (0.2%). Viskositas pada pengukuran polimer 1 (P1) sebesar 28,79 cp, polimer 2 (P2) sebesar 18,41 cp, surfaktan+Polimer 1 sebesar 11,07 cp, surfaktan+polimer 2 sebesar 9,28 cp. Recovery minyak pada injeksi Surfaktan (0.3%) + Polimer P1 (0.2%) sebesar 0,50 ml atau 11,0%, injeksi %), Surfaktan (0.3%) + Polimer P2 (0.2%) sebesar 0,45 ml atau 9,2%, injeksi Surfaktan (0.3%) Polimer P1 (0.15%) + Polimer P1 (0.2%) sebesar 0,90 ml atau 17,3%, injeksi Surfaktan (0.3%) Polimer P2 (0.15%) + Polimer P2 (0.2%) sebesar 0,85 ml atau 15,7%, injeksi Surfaktan (0.3%) + Surfaktan (0.3%) Polimer P1 (0.15%) + Polimer P1 (0.2%) sebesar 1,15 ml atau 23,0%, injeksi Surfaktan (0.3%) + Surfaktan (0.3%) Polimer P2 (0.15%) + Polimer P2 (0.2%) sebesar 1,05 ml atau 19,8%. Recovery minyak yang didapat dari tahap waterflood berada pada kisaran 50.50% sampai 59.60% IOIP (Initial Oil In Place). Oil Recovery yang didapat oleh uji core flood menggunakan injeksi chemical berada di angka 9.2% - 23%, sehingga total recovery yang diperoleh 61.2% sampai 76.90%. Dari injeksi chemical yang paling efektif dilakukan yaitu dengan injeksi Surfaktan (0.3%) + Surfaktan (0.3%) Polimer P1 (0.15%) + Polimer P1 (0.2%) dengan recovery factor (RF) 1,15 ml atau 23%.
