Abstract

This study evaluates the suitability of silica sand from Rupat Island, Indonesia, as a natural proppant candidate for hydraulic fracturing applications, based on API RP19C specifications. The investigation involved three samples: unmodified silica sand, 5 % resin-coated sand, and 10 % resin-coated sand. Key properties assessed include roundness and sphericity, bulk density, turbidity, acid solubility, and crush resistance. The results show a significant improvement in roundness and sphericity with resin coating, with the 10 % coated sample reaching a value of 0.7—meeting the API minimum requirement of >0.6. All samples exhibited bulk density values exceeding the API minimum of 1.5 g/cc, specifically 1.53 g/cc, 1.58 g/cc, and 1.60 g/cc, respectively. Turbidity values were also low, ranging from 20 to 38 NTU, well below the API limit of 250 NTU. Acid solubility decreased with increasing resin fraction, from 2.8 % (uncoated) to 2 % and 1.2 %, all within the acceptable API limit of <3 %. In the crush resistance test using 40/70 mesh, all samples demonstrated acceptable levels of particle degradation: 6.7% at 2000 psi for uncoated sand, and 9 % and 8 % at 6000 psi for resin-coated samples—each remaining below the API maximum of 10 %. These findings suggest that Rupat Island silica sand, when modified with resin coating, holds strong potential as an alternative proppant for hydraulic fracturing operations.

Abstract

The reduction in oil production rates due to the formation of calcium carbonate (CaCO₃) scale deposits on production pipes is a common problem in upstream oil and gas operations. This study aims to evaluate the effectiveness of acetic acid produced from pineapple peel fermentation, alone and in combination with hydrochloric acid (HCl), as an organic-based scale-removal agent, with EDTA-2Na used as a comparison via chelation. The research methods included acetic acid extraction via two-stage fermentation, characterization of functional groups by infrared spectroscopy (FTIR), and analysis of mineral scale composition by X-ray fluorescence (XRF). Scale testing was carried out using the weight-loss method with immersion times of 30, 60, and 90 minutes. FTIR results showed the presence of characteristic organic acid functional groups, while XRF results confirmed that the scale was dominated by calcium as the main component of CaCO₃. The test results showed that the mixture of acetic acid and HCl provided the highest effectiveness with a mass loss of 0.43 grams at 90 minutes, followed by pure acetic acid at 0.36 grams, while EDTA-2Na produced a reduction of 0.08 grams. These results indicate that biomass-based acetic acid has the potential to be a more environmentally friendly alternative for scale removal in oil and gas production piping systems.

Abstract

Biodiesel di Indonesia umumnya berasa dari ester metil asam lemak yang diproduksi dari minyak sawit. Biodiesel telah digunakan sebagai bahan baku dalam produksi biosolar. Saat ini, Indonesia menerapkan B40 yang berarti dalam biosolar terkandung 40 %(v/v) biodiesel. Kandungan biodiesel dapat dianalisa menggunakan Nuclear Magnetic Resonance (NMR), Kromatografi Gas (GC), dan spektroskopi Fourier Transform Infra Merah (FTIR). Saat ini peralatan komersial untuk menentukan komposisi biosolar menggunakan prinsip FTIR. Pada penelitian telah dilakukan pengukuran biodiesel dalam biosolar menggunakan metode FTIR-ATR dan GC-FID. Penelitian dilakukan menggunakan masing-masing dua jenis biodiesel dan dua jenis minyak solar yang dikombinasikan menghasilkan empat variasi berbeda. Penentuan kadar biodiesel dengan metode FTIR-ATR dilakukan berdasarkan luas serapan gugus karbonil (C=O) di 1742 cm-1 yang berasal dari biodiesel. Data yang diperoleh dari hasil análisis menggunakan FTIR-ATR diolah menjadi tiga set bilangan gelombang, yaitu 1692 – 1800 cm-1, 1700 – 1800 cm-1, 1670 – 11851 cm-1 sesuai standar ASTM D7371-14(2022) dan rentang 1726 - 1776 cm-1. Analisis menggunakan metode GC-FID dilakukan dengan menggunakan metil heksadekanoat sebagai puncak acuan. Hasil pengolahan data menunjukkan bahwa analisis menggunakan GC-FID memberikan linearitas dan akurasi lebih baik pada rentang kadar 1 – 50 %(v/v) biodiesel dalam biosolar.

Abstract

The stability of water-in-crude oil emulsions poses a significant challenge in oil production and refining processes, particularly in KB Field, which exhibits highly stable emulsion characteristics. This study aims to evaluate the effectiveness of two types of demulsifiers—Demulsifier A and Demulsifier B—in separating water from crude oil emulsions using the bottle test method. Tests were conducted at varying concentrations (0, 200, 300, and 400 ppm), with analysis of water drop and Sediment and Water (S&W) values across two sample zones: top cut and mix cut. Results indicate that Demulsifier A demonstrates superior performance, reducing S&W values to as low as 0.2% at 400 ppm, while Demulsifier B shows stagnation at higher concentrations. These findings contribute to the selection of more efficient chemical agents for demulsification processes and support the development of more sustainable and cost-effective production strategies. The study also highlights the importance of quantitative approaches in demulsifier evaluation, which remain limited in local literature.

Abstract

The Tarakan Basin is a hydrocarbon-bearing basin with significant geological complexity. This research in the Bunyu Tapa field aims to characterize the reservoir using the acoustic impedance seismic inversion and multiattribute seismic analysis. Through the approach of seismic inversion of acoustic impedance and multiattribute seismic, it is expected to map well the distribution of reservoir prospect areas in the Bunyu Tapa area based on petrophysical analysis. This research focuses on the Intra Bunyu interval which is part of the Bunyu Formation. The results showed that acoustic impedance inversion of the Intra Bunyu successfully identified variations in reservoir properties. Through linear regression analysis between acoustic impedance and porosity, a negative relationship was found that allows estimation of porosity distribution. This study also analyzed the contribution of multiattribute approach with neural network to validate and enrich the interpretation results. Based on the results of seismic interpretation, seismic inversion of acoustic impedance, and prediction of porosity property distribution based on the linear regression relationship between acoustic impedance and porosity, it is known that the Top Intra Bunyu area is a potential reservoir area with an acoustic impedance value of 3200 - 4800 ((m/s)*(g/cc)) with a porosity value of 5% to 35%. This research contributes to the understanding of the structure and characteristics of reservoirs in the Tarakan Basin, which can support the exploration and exploitation of hydrocarbon resources in the region

Abstract

Palm kernel oil (PKO) is a potential raw material for biosurfactant production dua to its high content of medium-chain fatty acids, particularly lauric acid. This study aimed to synthesize methyl ester sulfonate (MES) biosurfactant from PKO and evaluate their performance in reducing interfacial tension and increasing oil recovery. Synthesis was carried out through a transesterification reaction using H2SO4 as a catalyst, followed by sulfonation. Characterization was carried out through measurement of physical properties (pH, density, viscosity), fatty acid composition (GC-MS), and FTIR analysis. Performance test included interfacial tension (IFT). Critical micelle concentration (CMC), adsorption on porous media, toxicity testing, and oil recovery test under simulated reservoir conditions (T = 50 0C, salinity 10,000 ppm). The results showed that the biosurfactant from PKO was able to reduce the IFT from 15.2 m N/m (50 ppm) to 1.2 m N/m (1000 ppm), with the CMC achieved at a concentration of 500 ppm. Biosurfactant adsorption was in the range of 28-32%, while toxicity tests showed an increase in mortality of up to 85% at 1000 ppm. Flooding tests showed an increase in oil recovery of up to 24.3% at 1000 ppm. Thus, the biosurfactant from PKO has potential as an Enhanced Oil Recovery (EOR) agent, although further studies regarding its toxicity are needed.

Abstract

The decline in oil well production is caused by natural factors such as reservoir pressure decline, increased water content, and high gas-liquid ratio (GLR), which also affect artificial lift performance. Electric Submersible Pump (ESP) is chosen as a solution, despite challenges such as gas lock and uneven wear in high GLR directional wells. ESP planning focused on component design, such as motor protectors and the use of Single Feature Rotary Gas Separators to address gas issues. The implementation of ESP in three wells showed a significant increase in production: Well AZ-049 increased by 12.7% (from 902 BFPD to 1017 BFPD), Well AZ-084 increased by 86%, and Well AZ-025 achieved the highest increase of 124% (from 246 BFPD to 551 BFPD). Collectively, this project generated a total gross production of 2817 BFPD and a net oil gain of 364.5 BOPD. Economic analysis shows excellent financial viability with a Net Present Value (NPV) of $3.089 million, a Profitability Index (PI) of 30.07, and a Rate of Return (ROR) of 2761.33%. Liquidity risk is very low, indicated by a Pay Out Time (POT) of only 0.035 years (approximately 13 days). These results indicate that the ESP project is a highly potential investment.
