Abstract

One of the ways in improving oil recovery from a reservoir is by injecting surfactant. The use of surfactant is intended to decrease the interfacial tension between oil and water in order to bring the oil out of the pore stones of the reservoir. It is a good chance to develop the kind of vegetable oil based surfactant which is from rubber seed oil. According to the data of the Directorate General of Plantation year 2013, Indonesia is one of the countries which have the largest rubber plantation in the world. Yet, rubber seed is wasted so far. Rubber seed contains vegetable oil which can be developed into methyl ester sulfonate based surfactant (MES). Due to the carbonate formation that will be tested, hence, the best formulation of MES based surfactant for Enhanced Oil Recovery (EOR) application in this formation is a formula with MES based surfactant composition of 0.3%, Na2CO3 0.3% and salinity 15.000 ppm. In this particular study, surfactant formula is added into carbonate reservoir sample taken from Prabumulih by creating concentration from surfactant formula and reservoir sample as much as 5%, 10%, 15% and blank. The best MES based surfactant formula to be applied on oil industry of carbonate field is the surfactant formula with 15% dosage composition.

Abstract

Penelitian ini bertujuan untuk mengetahui karakteristik petrologi dan geokimia granitoida dan terjadinya mineralisasi hidrotermal di daerah Mehanggin, Kabupaten Muaradua, Provinsi Sumatera Selatan. Metode penelitian dilakukan dengan pemetaan geologi rinci dan beberapa analisis laboratorium termasuk petrografi, mikroskop bijih, XRD dan geokimia batuan massal untuk beberapa sampel yang representatif. Secara geologis, daerah penelitian ditempati oleh enam unit batuan dari yang muda ke tua meliputi tufa pumisan, batupasir kuarsa, konglomerat kuarsa, breksi autoklastik, granit dan andesit.. Secara mineralisasi, granit Garba terdiri dari kuarsa, plagioklas, K-feldspar, piroksen, biotit dan hornblenda. Ilimetit juga hadir dalam jumlah yang kecil pada batuan. Geokimia granit menunjukan rasio Al2O3/CaO+K2O > 1,1. Oleh karena itu, berdasarkan studi mineralogi dan geokimia, granit Garba dikategorikan ke jenis granit tipe-S peraluminous. Granitoids teralterasi secara lemah menjadi tipe kloritik-epidotik (propilitik). Perubahan serisit (liat mineral) juga dikenali. Studi mikroskopis bijih menunjukkan bahwa granitoid Garba termasuk granit dan andesit telah mengalami termineralisasi lemah. Pirit dan kalkopirit jelas terlihat pada pola disebarluaskan dan dalam bentuk urat , serta mineral ilimenit yang hadir dalam sayatan. Dan Diagram Harker granitoid memperlihatkan bahwa senyawa SiO2 berkorelasi negatif terhadap senyawa-senyawa utama TiO2, Al2O3, Fe2O3, CaO, K2O, Na2O, MnO, MgO dan P2O5 yang merefleksikan pengaruh fraksiasi magma. Afanitas magmanya tergolong dalam high kalk-alkali. Berdasarkan ploting unsur utama MgO, Al2O3 dan FeO, granitoid terbentuk pada island arc and active continental margin. Granitoida Garba tipe-S bisa menjadi batuan induk potensial untuk mineralisasi timah di daerah tersebut. Eksplorasi lanjutan sangat diperlukan untuk menemukan endapan timah dan bijih hidrotermal yang ekonomis.

Abstract

The presence of silicified coal characterized several coal seam in Muara Enim Formation and become the important issue in coal mining industry. Silicified coal found in the South of Tanjung Agung District, Muara Enim Regency, South Sumatra. The occurence of silica presume related to the volcanic activity during the late miocene along the regression phase that affected the sedimentation process of Muara Enim Formation. Tuffaceous sandstone layer can possibly recognized as the main source of the silica. Aquisition data process done by observing the research area and several previous study. Sampels used were taken from several coal outcrop. Petrography analysis used to explain the characteristic of silicified coal microscopically and used to analyze the possibility of its genesis. The presence of silicified coal characterized the coal seam occur in southern limb of Tanjung Agung Syncline that distinguish it with the coal seam on northern limb. Macroscophically, silicified coal found generally blackish gray color, hard, in the form of lenses and layering and microscophically mostly dominated by crystal quartz in the form of detrital and diagenetic silica. Silicified coal may cause problems in coal mining activity. Particular treatment should be applied during the mining activity because of its hardness.
