Abstract

The majority of petroleum production comes from the brown field where production has decreased from year to year in Indonesia. To increase the recovery factor of petroleum from the reservoir, an advanced step of production is required, Enhanced Oil Recovery (EOR), which can optimize the depletion of old oil fields. EOR is the application of technology that requires cost, technology and high risk. Therefore, before implementing EOR, in a field, we must carefully evaluate both technically and economically to obtain an optimal additional recovery. This research was conducted to increase oil production by injection of Methyl Ester Sulfonate (MES). This study begins with a screening parameter crude oil, formation water, Berea’s core, and determination of phase behavior, interfacial tension (IFT), thermal stability, imbibition, and core flooding tests. The result for concentratin optimum in 0.3% MES and had IFT 0.3267 dyne/cm. The results of core flooding tests are: Recovery factor of waterflooding is 33.95 % and recovery factor of MES injection is 4.19 %.

Abstract

In this paper, a numerical study was conducted to investigate the effect of spatial heterogeneity of multiple porosity fields on oil recovery, residual oil saturation,   polymer retained, and polymer adsorption. The generated porosity fields were applied to UTCHEM for simulating polymer and water flooding in heterogeneous two-layered porous media. From the analysis, the increase of reservoir heterogeneity resulted in higher polymer retention and lower polymer adsorption. In general, polymer flooding results in more balance residual oil saturation in the upper and lower layer than water flooding. This indicated that the vertical sweep efficiency of polymer flooding was better than water flooding. Residual oil saturation ratio between layers after water or polymer flooding was about equal along with the increase of reservoir heterogeneity. Spatial heterogeneity of multiple porosity fields had only a small effect on recovery factor. The variation of the recovery factor of polymer and water flooding due to the reservoir heterogeneity was under 1%.

Abstract

One of the zeolite producing areas in Indonesia is Sukabumi. Natural zeolite originating from Sukabumi is composed of three main types of minerals: mordenite, clinoptilolite, and quartz. Zeolite as a catalyst can be improved by carrying out physical and chemical activation processes. Physically the catalyst can be activated by reducing the size of the zeolite through the grinding and sieving method. This physical activation process can increase the surface area of the zeolite. In this study, variations in the size of zeolite 80 mesh and 100 mesh were carried out that chemically activated by the acid activation method through immersion of natural zeolite with HCl and HF from this acid activation process it will increase the acidity of the zeolite. Measurement of functional groups and chemical compounds in activated zeolite using XRF and FTIR. The results of XRF analysis showed that the SiO2 content in 80 mesh zeolite was 69.5% and in 100 mesh zeolite was 82.1% and the FTIR analysis showed the presence of the C-H alkene functional group at a wavelength of 675-995 cm-1, ring C-H aromatic at a wavelength of 690-900 cm-1, C-O alcohol/ether/carboxylic acid/ester at wavelength 1610-1680 cm-1, functional group C=C alkene 1610-1680 cm-1, the O-H functional group is carboxylic acid at a wavelength of 3500-3650 cm-1 and an alcohol monomer/phenol O-H functional group at a wavelength of 3590-3650 cm-1.
