Abstract

The Binio Formation, the target of this study, is located in the Lotus Field, Central Sumatra Basin. P-impedance parameters from acoustic impedance (AI) inversion analysis are used to identify rock lithology and fluid content. Petrophysical analysis was conducted on three wells using well log data to determine reservoir characteristics and identify prospect zones. The reservoir in the Binio Formation is a sandstone that is considered favourable for hydrocarbon accumulation. This study determines lithology, fluid content and reservoir structure. Sensitivity analysis showed that the porosity log parameter is sensitive to lithological separation. A potential hydrocarbon area was detected using seismic methods. Model-based inversion methods showed that the AI values of the sandstone reservoir ranged from 9,670 to 27,070 (ft/s)(gr/cc). The geological structure in the Lotus Field is generally quite complex, consisting of an anticline structure and a normal fault. Following conversion to porosity, the effective porosity value for the P1 reservoir was 0.4 (fraction). The root mean square attribute results showed the presence of bright spots, and the reservoir was clearly detected within the 10 ms analysis window. The prospect zone in the P1 well lies at a depth of 2,400–2,800 ft, with interpretation indicating that the fluid content is gas.

Abstract

The upstream oil and gas industry in the production sector is made up of numerous lifting activities, carried out in wells, as well as storage and sales tanks. Preliminary research has been conducted on the process of gathering systems from each point of the production facility unit to determine the pressure loss, blockage or leakage problems. The findings showed that oil spill points due to the accumulation of crude spills mixed with other sediments was approximately 2043 m3 per week. B3 waste disposal is often a burden for companies because it is expensive without revenue value, while solid waste has economic value and can be reused. Therefore, this research aimed to evaluate the use of solid waste containing 48.01% Total Petroleum Hydrocarbons (TPH), including mineral and metal sediments, namely XRD, XRF and AAS tests as basic materials for road asphalt. The result showed that the use of solid waste with a density specification of 0.92 and a Pour Point of 1700 C as the basic material for making road asphalt mixed with aggregate achieved an initial setting time of less than 5 minutes and Compressive Strength of 0.25 MPa less than the 2 MPa standard value at R20. In conclusion, the Asphalt Resin Paraffinic Sediment obtained from solid waste was less than 10% and could not be used for road asphalt hardening, hence the need to add commercial asphalt and other additives.

Abstract

This study aims to evaluate the ability of Aspergillus niger to produce biosurfactants as a cost-effective and environmentally friendly alternative for the microbial-enhanced oil recovery (MEOR) process. Biosurfactants were produced using different carbon sources: waste cooking oil, liquid paraffin, and tapioca flour in Stone Mineral Salt Solution media. The growth and production of biosurfactants from these sources were analyzed through oil displacement tests, emulsification activity, and surface tension measurements. Tapioca flour emerged as the best carbon source, achieving the highest oil displacement area of 6 cm and an emulsification index of 51.3%. These findings suggest that biosurfactants obtained from Aspergillus niger have significant potential for MEOR applications, providing an eco-friendly solution for enhanced oil recovery.

Abstract

The aim of this study is to analyze the role of the upstream oil and gas sector within Indonesia's economy in terms of its linkage to other sectors and the multiplier effect it produces. The input-output (IO) analysis method is applied by calculating the total, backward, and forward linkage index and multiplier effect index values of the upstream oil and gas sector. Building upon a previous study using the 2005 BPS IO Database updated in 2010 (2005 IO), this study used the 2010 IO Database released by BPS in 2015 (2010 IO) and the 2016 IO Database released in 2021 (2016 IO), processing the data using Python-based software. Based on the calculation using 2010 IO Database, there were 93 sectors with linkage to the upstream oil sector and 104 with linkage to the upstream gas sector, whereas the 2016 IO Database identified 96 sectors with linkage to the upstream oil sector and 113 with linkage to the upstream gas sector. Simulated calculation and analysis results revealed that there was an increase in total (backward and forward) linkage index values of the upstream oil and gas sector, from 3.8801 to 4.0826 for the upstream oil sector and from 3.1256 to 3.3940 for the upstream gas sector. In regard with multiplier effect, simulated calculation results also pointed towards an increase in total multiplier index values, from 6.1855 to 7.8943 for the upstream oil sector and from 4.9828 to 6.5630 for the upstream gas sector. The increase in total multiplier index in the national upstream oil and gas sector correlates with an increase in linkage between the upstream oil and gas sector and other sectors in Indonesia's economy as a whole, both backward and forward. Analysis results showed that the greater the multiplier index reported by a sector with linkage to the upstream oil and gas sector, the greater the total multiplier index produced in the upstream oil and gas sector.

Abstract

Wax deposition is a common phenomenon that restricts flow in tubing, causing production decline. In the studied well, this decline is linked to wax thickness increasing from 0.0021 inches (Day 1) to 0.0114 inches (Day 7), occurring as fluid temperatures drop below 153.5°F. An Electrical Submersible Pump (ESP) is used to address this, but it impacts thermal conditions and flow behavior, especially in gassy wells. Therefore, a transient simulation is required to analyze wax deposition and flow behavior under ESP installation. This study performs a 7-day transient simulation using OLGA 2022.1.0 on the "X" well, a gassy well (700 scf/bbl GOR) with 38% wax content, utilizing a 70-stage DN610 ESP. Results show wax deposition begins on Day 1 (max 0.0021 inches) and thickens to 0.0114 inches by Day 7. Flow patterns vary along the tubing: stratified flow is dominant from the pump setting depth to KOP, while slug flow dominates from KOP to the tubing head. Annular flow was observed at the tubing head on several days. Sensitivity analysis revealed that more ESP stages result in more wax deposition. This is because the ESP increases the production rate; as more oil flows, more contained wax precipitates and deposits. The least wax was observed in the scenario with no ESP. This work demonstrates how ESP-induced liquid holdup and slug/annular transitions accelerate wax deposition and emphasizes the importance of transient simulation in predicting production risks.

Abstract

Household sector is significantly influenced by population and economic factors, which are two key variables in energy consumption projections. For example, the selection of East Kalimantan as the location for the Nusantara Capital City through Law Number 3 of 2022 increased the household energy consumption in the area. It was observed that cooking and electricity needs were dominated by the usage of oil and gas, leading to the need for energy system modeling to design appropriate energy policies, avoid dependence on fossil fuels, and control CO2 emissions in the future. Therefore, this research aims to forecast oil and gas demand of households up to 2060 based on several scenarios. A bottom-up method was dynamically connected to multiple variables for the forecast due to its ability to provide essential feedback loops, delays, and interactions required for energy system. The results showed that Business as Usual (BaU) scenario led to 28,96 million Barrel Oil Equivalent (BOE) and 8,09 million tons of emission in 2060 while Indonesian Capital City (IKN) scenario had 35,65 million and 9,8 million tons respectively. It was further reported that low carbon (LC) scenario produced 3,5 million tons of emissions.

Abstract

This paper discusses the benefits of using a smart alert system for the detection of geological boundaries, and how this system enhances decision making during geosteering operations. Monitoring multiple wells in a high operation environment is a big challenge for geosteering operations. Using Managed By Exception (MBE), an integrated smart system that produces an alert when the well deviates from the target zone while drilling is a solution which can greatly improve operations efficiency. Real-time drilling data is processed through the integrated alert system by a set of algorithms that can recognize when the drill-bit goes out of the reservoir. This is based on Logging While Drilling (LWD) characteristics. The smart system can then recommend if an adjustment in inclination is required to keep the best contact with the reservoir. This creates a seamless geosteering workflow. Geologists and petrophysicists can now leverage a comprehensive understanding of real-time data infrastructure, log formats, and data processing. This fosters effective communication about reservoir condition We believe MBE setup significantly improves geosteering efficiency and encourages others to utilize the power of real-time data analysis.

Abstract

As oil and gas fields mature, the volume of produced water can increase substantially, often exceeding 90% of total production. This water cannot be directly discharged or reused due to harmful contaminants that pose considerable environmental risks. One major challenge is the absence of efficient, eco-friendly, and cost-effective filtration media for its treatment. This study aimed to develop and assess an alternative adsorbent derived from jenitri seeds, chemically activated with potassium hydroxide (KOH) at controlled temperatures. The primary goal was to identify a more effective and sustainable adsorbent than those currently used in oilfield operations. The methodology involved the preparation of this adsorbent, Its physicochemical characterization included bulk density measurement, scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) analyses, along with performance testing through filtration, benchmarked against natural adsorbents such as candlenut and walnut. The KOH-activated jenitri demonstrated superior pollutant removal performance, primarily due to enhanced porosity and surface area resulting from the activation process. It exhibited the lowest bulk density (0.6 g/mL), an optimal porous structure as revealed by SEM, and the presence of active functional groups such as –OH, C=O, and C–O, identified through FTIR analysis. In filtration tests, KOH-activated jenitri effectively reduced total dissolved solids (TDS) to 600 mg/L and turbidity to 100–200 nephelometric turbidity units (NTU), outperforming natural jenitri, candlenut, and walnut, whose limited porosity contributed to lower adsorption efficiency

Abstract

The use of electromagnetic heating mechanisms in heavy oil production operations is widely limited in Indonesia. In this context, there is a need for in-depth research regarding the effectiveness of the method. Therefore, this research aimed to discuss the efficacy of heating method through Recovery Factor (RF) analysis using imbibition with electromagnetic waves and the addition of nanopowder. The results showed that the speed of heating and RF imbibition using electromagnetic waves was higher than conventional imbibition. In addition, ferrous oxide nanopowder produced the highest heating speed and RF of 38.39% below the expected value. Further research could be conducted regarding changes in the wettability of rock due to electromagnetic heating and nanopowder required to answer the problem.

Abstract

The global petroleum refining industry faces increasing pressure to optimize resource utilization while ensuring environmental sustainability. This challenge is further intensified by the rising demand for lighter, cleaner fuels and heavier crude oil feedstocks. The Delayed Coking Unit (DCU) plays an important role in refining processes by converting vacuum residue into valuable products such as Liquefied Petroleum Gas (LPG), diesel, naphtha, and green coke. The LPG market, currently valued at $113.7 billion, is projected to grow to $165.1 billion by 2033. Within this process, the deethanizer column utilizes pressurized distillation to separate ethane (C2) from LPG. According to evaluation results, the column's feed flow was recorded at 83.7 tons per day, with a feed temperature of 102.61°C and a top column pressure of 18.84 kg/cm². The feed composition data was obtained through laboratory analysis. According to the calculation, the theoretical tray number was 17, the reflux ratio was 0.9936, and the total tray efficiency was 56.57%. The optimization of deethanizer column operating conditions was carried out by increasing the bottom product yield, which aimed to determine the optimum point with the greatest LPG yield. Based on a trial-and-error using Aspen Hysys V14 software, the optimum conditions were identified when the column was operated at 110℃ reboiler temperature and reflux ratio 2, which could increase LPG yield to 73.21 tons/day with 98.1% w/w purity. Economically, the profit increased from $18,444,932.92/year to $22,640,582.13/year
