Published: February 2025

This study aims to determine the efficiency of the electrical power generated from the Micro hydroPower Plant (MHP) prototype on the flow of tributaries of the tukad sungi Banjar Ganter AbianTuwung Village. The efficiency obtained can be used as a parameter to determine how much theavailable hydraulic power potential can be utilized into electrical power. This research uses aquantitative analysis method which involves direct measurement of operational parameters suchas water discharge, water fall height (head), electric voltage and electric current generated in theMHP prototype. Measurement of the electrical power generated by the MHP prototype producesdifferent efficiencies according to the variation in the number of loads used, the highest efficiencyof 7.75% is obtained when measuring using a load in the form of 6 12V 40W DC LED lights. Theefficiency obtained is relatively small, this is because the electric power generated is only 37.54Wwhile the available hydraulic power is 484.12W. The low electrical power generated is due todeviations in the specifications of the load used, so that the power generated does not match thepower specifications listed on the load used.
Контур истории «Известий Восточного института»
Authors: БАРБЕНКО Ярослав Александрович
Published: February 2025

История «Известий Восточного института» является отражением гораздо более широких явлений, чем научная издательская деятельность. Возникнув в самом конце XIX в. как часть процесса становления научного практического востоковедения во Владивостоке, журнал сохранил практическую направленность и в XXI в. «Известия» пережили войны и революции первой четверти XX в. в России, в 30‑е гг. оказались вытесненными другими изданиями, но в начале 90‑х гг. были возрождены неравнодушными и трудолюбивыми востоковедами. За прошедшие тридцать лет «Известия» превратились из ежегодника в квартальное издание и стали популярной дискуссионной площадкой для востоковедов и представителей смежных направлений науки.

The history of the Oriental Institute Journal is a reflection of much broader phenomena than scientific publishing. Having emerged at the very end of the 19th century as part of the process of formation of scientific practical Oriental studies in Vladivostok, The Journal retained its practical focus and in the 21st century The Journal survived the wars and revolutions of the first quarter of the 20th century in Russia, in the 30s was replaced by other publications, but in the early 90s they were revived by caring and hardworking Orientalists. Over the past thirty years, The Journal has transformed from a yearbook into a quarterly publication and has become a popular discussion platform for Orientalists and representatives of related research fields.

Dramaturgy and the Phenomenon of Instagram Multi-Account Usage Among Gen Z in Bali
Authors: Winduwati Septia , Irena Lydia
Published: February 2025

Generation Z, born between 1997 and 2012, has grown up in a digital technology era that has shaped their communication and interaction styles, particularly through social media platforms like Instagram. They are highly active on this platform, with 58% spending more than an hour each day. This study aims to analyze how Generation Z utilizes multiple accounts on Instagram using Erving Goffman's dramaturgical theory, which describes social interactions as performances where individuals play roles according to social contexts. This research is expected to contribute to understanding the construction of digital identities and social roles of Generation Z. A qualitative approach is used in this study to describe the findings from Generation Z Instagram users with multiple accounts in Bali. Data were collected through in-depth interviews, field observations, and document studies, and analyzed using thematic analysis techniques. The results indicate that Generation Z uses multiple Instagram accounts to separate "front stage" and "back stage" in their identity management. The main account serves for personal branding and professional image, while the secondary account is used for more free-form self-expression. However, although multi-account management helps in managing identities, some informants still experience conflicts in maintaining their image on the main account and authenticity on the secondary account. Identity management in this digital era reflects their ability to navigate diverse social demands and balance public image with personal expression in the digital world.
Case report: Unexpected presentation of Wellens’ syndrome in Public Health Centers
Authors: Afandy Jonathan Edbert , Taslim  , Putra Swastya Dwi
Published: February 2025

Electrocardiography (ECG) is an essential tool for diagnosing and risk-stratifying acute coronary syndrome patients. Only 20% of acute ischemia ECG changes are recognized by emergency medical service (EMS) providers. Wellens’ syndrome is an ECG characteristic, as certain ST-T segment abnormalities in the setting of impending myocardial infarction (MI) patients suggestively caused by critical stenosis in the proximal left anterior descending (LAD) artery. Myocardial infarction from a culprit lesion in the LAD artery is related to worse clinical outcomes. The first patient was a 27-year-old man smoker who presented with epigastric pain accompanied by shortness of breath in the past 1 hour. His blood pressure was 170/100 mmHg and physical examination revealed epigastric tenderness. ECG revealed biphasic T waves in leads V2-V5, suggestive of Wellens type A. The second patient was a 37-year-old man who presented after being stung by an insect 15 minutes before. Upon observation, the patient suddenly experienced left-sided chest pain accompanied by diaphoresis. ECG revealed inverted T waves in leads V2-V4, suggestive of Wellens type B. Further history-taking revealed that he had experienced this kind of symptoms three months prior and had a history of hypertension, dyslipidemia, and a current smoker. Unfortunately, both patients refused to be referred for further examination and management. Physicians and EMS providers should be aware of Wellen’s syndrome. Misinterpretation of this ECG characteristic could lead to fatal outcomes. Educating patients thoroughly about their condition is also important.

Metamodeling Approach for Wing Structural Sizing of Box-Wing Aircraft
Authors: Palaia Giuseppe , Salem Karim Abu , Binante Vincenzo , Carrera Erasmo
Published: February 2025

This paper presents a predictive metamodel, built on a finite element method (FEM)-based design of experiment (DoE), developed for the structural design of a box wing. For this configuration, statistical or semi-empirical predictions are not available for the conceptual design. The aim, hence, is to develop a fast and reliable structural sizing model for the early stages of the aircraft design process. The proposed model can predict maximum stress and wing deflections for a wide range of combinations of wing design variables related to geometrical (e.g., aspect ratio, span, surface) and structural parameters (e.g., stringer thickness and shape, skin thickness). The metamodel, built by handling the information from an FEM-based DoE database, has been implemented into multidisciplinary design frameworks for the conceptual design of box-wing aircraft of different sizes and geometries. The tool proved to be effective for optimizing lifting system structure, considering wing structural mass as the objective function. The accuracy of the proposed metamodel is assessed by comparing the results of different box-wing structural solutions sized with both the DoE-based surrogate model and FEM analyses; the comparisons showed a good accuracy for the metamodel, with a maximum error on the estimation of structural mass below 4% and maximum Von Mises stress below 6%.
Employee Perspectives on Inclusivity in Ethiopian Workplaces: Linking Perception to Performance
Authors: Tenessa Daregot Berihun
Published: February 2025

Promoting inclusion in the workplace is an important policy component for developing the national labour force and market. However, this crucial issue has received insufficient attention in Ethiopia. This study aims to initiate the assessment of inclusivity in Ethiopia by analysing workplace performances regarding inclusiveness and its link to major inclusion criteria. This study data came from a national survey on the labour market and inclusiveness, which were then analysed using the partial least square structural equation model. The study results shed light on the positive impact of important inclusion elements such as diversity climate, fairness, maintaining employee uniqueness, establishing an enabling environment, and enhancing organisational strategies and policies consistent with inclusive principles. However, factors such as belongingness, avoidance of discrimination, and training and skills development were perceived as having an adverse impact on workplace inclusivity. This study addresses an important but understudied topic: the effects of inclusion instruments on the perceptions of employees in one of the least developing countries. The results regarding the key inclusion instruments such as diversity, fairness and support for employee uniqueness, combined with a nuanced examination of the potential drawbacks of belongingness, anti-discrimination efforts and training, are new to Ethiopian literature. These results provide valuable insights for academics and labour market practitioners working to improve employee inclusivity. The study suggests that policymakers in the Ethiopian labour market sector consider the revision of inclusion instruments that focus on belongingness, anti-discrimination efforts and training.
Espíritus, almas y culturas. Una idea de nación muy alemana
Authors: Polo Blanco Jorge
Published: February 2025

En el presente trabajo se examinarán críticamente ciertos aspectos de la filosofía romántico-idealista alemana, en lo que tiene que ver con la gestación de una idea muy específica de nación. El análisis se centrará en Wilhelm von Humboldt, Herder, Hegel y Fichte. Podrá comprobarse que las propuestas teóricas de estas cuatro insignes figuras del pensamiento germánico contribuyeron de manera decisiva a forjar una determinada idea de cultura, que a su vez se conectaba con una particular concepción de la lengua. Desde ese universo filosófico e ideológico terminó cuajando, en el ámbito del pensamiento alemán, un tipo de nacionalismo con características propias. Debe señalarse que el trabajo se fundamentará, en muy buena medida, en los planteamientos críticos del filósofo español Gustavo Bueno.

Mechanism and Oil-Water Pressure Drop of Unique Autonomous Inflow Control Device Under Different Water Cut: Water Control Performance of AICD in Large Bottom Water Reservoir in South Sudan
Authors: Khan Javed Akbar , Chen Yanhong
Published: February 2025

Water control for a longer time is a challenge. This paper present the effectiveness of water control performance of existing devices and valves including Inflow Control Devices (ICD), Autonomous Inflow Control Devices (AICD), and Autonomous Inflow Control Valves (AICV) in various wells. Any device is usually considered based on working principles and performance at the start of production. However, consideration of the structural integrity of a device is important for its longer effectiveness in controlling water until the end. Also, the ICV, ICD/AICD/AICV, DHPG, and PPL selection depend on reservoir condition. The presented comparison can be part of the selection procedure of these options. It shows realistically smart option in the scale/corrosive/hydrate environments to control water for a longer time. This paper shows advanced intelligent water control technology that can control water influx, enhance oil recovery, and manage pressure in multi-layer reservoirs. The innovative design of the inflow channel structure restricts water based on viscosity and density differences of fluids. It can automatically adjust pressure drop, has no moving parts, has an integrated design, and can function throughout the entire life cycle of the oil well. The mechanism of advanced Flowise® AICD is illustrated which shows significant pressure drops for water, and its effectiveness under different water cuts. Finally, performances of AICD completion in a field operated by PETRONAS in South Sudan is presented. Apart from AICD completion, perforation in selected layers were performed for production enhancement solution. The following are the key results that show a significant reduction in water and high oil production after the work over; Before Flowise®: Water Cut = 92.9%; After Flowise®: Water Cut = 24.9%. Before Flowise®: Qo = 139bbl/d, Qw= 1819bbl/d; After Flowise®: Qo = 942bbl/d, Qw = 313bbl/d. This paper also discusses the optimal operating conditions for AICDs/AICVs, which rely on viscosity and density differences, in Oil/Water and Oil/Gas systems. It emphasizes the importance of selecting devices based on fluid characteristics for long-term performance. Moreover, the selection based on the structural stability and reliability of any device/valve is important for extended service life, highlighting the need for maintenance-free tools that align with a well's lifespan and effectively choke water at later stages.
Enhanced Reservoir Characterization of Thin Coal Seams: Application of 2D CNN-Based Seismic Impedance Inversion in Deep CBM Exploration
Authors: Li J. , Sun J. , Zhang H. , Sun X.
Published: February 2025

Deep coalbed methane (CBM) exploration presents unique challenges in reservoir characterization, particularly when dealing with thin coal seams. This study introduces a novel application of two-dimensional Convolutional Neural Network (2D CNN) based seismic impedance inversion for characterizing the No. 8 coal seam in China's Ordos Basin. By integrating post-stack 3D seismic data with limited well log information, we achieve high-resolution impedance inversion across an 80 km² deep CBM block in the Daji area. The results demonstrate superior accuracy in delineating thin coal seams compared to conventional inversion methods, validated through blind well tests. The resulting high-resolution impedance model enables well data-driven reservoir characterization, including porosity, ash content, and gas content estimation, providing crucial insights for well placement optimization and horizontal well trajectory design.
Unlocking Production Potential: First Successful Deployment of Multilateral Completion Feed-Through Selective Lateral Access Window with Intelligent Completion
Authors: AlRaml Haidar , Jacob Suresh , Widjaja Danang , Almasri Abdulrakeeb
Published: February 2025

The continuous advancement of multilateral completion technology has significantly transformed the oil and gas sector by enabling access to the reservoir. This has resulted in a substantial influence on production capacity. This abstract analyzes the latest progress in multilateral completion technology, specifically highlighting the incorporation of intelligent completion systems and lateral access throughout the lifespan of the well. The monitoring system has effectively utilized the acquired data, resulting in an improved accuracy and efficiency.

The efficacy of the Multilateral selective lateral access window has been demonstrated over the last few decades. It has successfully identified reservoir problems and implementing necessary measures based on obtained data. A substantial advancement in this field has been made by the creation of an advanced completion lateral access window. This window enables the placement of the PDHG and flow control devices below, and in close proximity to the reservoir. Consequently, there has been an improvement in the monitoring and control of the main bore. This innovation led to a substantial revolution in the implementation of drilling and completion deployment.

Practical knowledge has demonstrated that the integration of intelligent completion technology into gas and oil wells enables precise evaluation and strategic planning through the utilization of predictive analytics. By utilizing these analytics, one can gain a more profound comprehension of the reservoir's behavior. This allows for predicting its future performance and devise a proactive strategy for decision-making that will maximize the effectiveness of the well and the entire field. This ultimately leads to enhanced economic recovery and advantageous outcomes. The well has been granted favorable conditions because of the most recent development of a multilateral lateral access window, which enables access for any essential operation in order to maximize its capabilities. Preventing the necessity for well completion removal while enabling well access is a critical element in extending the well's operational lifespan. The progress made in multilateral technology has significantly expanded the practicality and relevance of the information, consequently improving the implementation of intelligent completion.

Significant advancements in this field are made possible by the Feed-Through selective lateral access window, which grants access for any required intervention for the duration of the well's existence.

This paper will focus on the recent development in multilateral completion technology, with a special emphasis on the capability to access both laterals in wells completed with intelligent completion.
Innovative Spacer and Slurry Design to Cure Severe Losses in Depleted Formations: A Case History from Southern Oman

Lost circulation while drilling is a common problem and a significant challenge in global drilling operations, particularly in weak, unconsolidated, or fractured formations. This phenomenon contributes to nonproductive time and imposes a substantial financial burden on well-construction economics, with estimated global costs reaching USD 2 billion annually (Alkinani et al. 2021). Despite numerous attempts to strengthen the wellbore through experimental processes and studies using modeling and simulation (Feng et al. 2024), these challenges persist, negatively impacting operations. The need to lift heavier and more viscous fluid through a narrow annulus increases equivalent circulating densities (ECDs), often exceeding the fracture limits of the target zone. This can lead to a lower-than-required cement top, potentially affecting overall well integrity and the final zonal isolation objective.

The traditional technique of curing losses using drilling fluid lost-circulation materials (LCMs) often serves as the final plan of attack. In parallel, recent advancements in bottom-hole assembly (BHA) technology have grown to meet the challenge of successfully drilling more sophisticated wellbore geometries under harsh conditions. One such advancement is the inclusion of a mechanically activated side port above the critical BHA components. This port, when activated, diverts the flow of cement fluid away from the BHA, reducing the potential risk of pumping cement fluid through the BHA. However, this solution does not address the added risks of a stuck BHA (Lavrov 2016) due to the inherent nature of the reactive cement systems and formation challenges. It is important to note that bypassing the fragile components of the BHA is not the only mitigation; an optimized job procedure should be assessed to minimize any potential error in reactive treatments. Traditionally, the safest procedure involves pulling the drill string and BHA to the surface, then using a single-purpose, sacrificial work string to place reactive fluids and thixotropic cement to seal and strengthen the problematic section. However, this approach incurs additional flat time due to the often high number of hours needed to trip and run the work string for treatment application. Meanwhile, losses continue to occur under static conditions, adding to the challenge. Finally, the inefficiencies of this approach are compounded if the problem of loss circulation while drilling requires multiple attempts for success.

Both cement quality and quantity play a major role in well integrity. The quality of bonding between casing and cement can be maintained if no downhole fluid losses occur during the cementing operation. For quantity aspect, relying only on the total cement volume pumped will not guarantee that the planned cement height in annulus is achieved. During job execution an induced fracture might cause considerable cement column to be lost into the opened fracture-zone.

The reason for this higher bottomhole pressure are primarily due to the high rheology of the cement slurry and spacers and also the annular space between the casing assembly and bore hole is lesser as compared to the drilling assembly during drilling phase which generates higher annular friction pressure losses aiding to the high bottomhole pressure. In addition the density of the slurry and spacer is usually higher than the drilling fluid which also further increases the bottomhole pressure. All these three factors make the likelihood of lost circulation more than during the preceding drilling phase.

The case study highlights how these challenges were addressed during cementing. Initially by designing a lighter mud density used in combination of surface back pressure, SBP improving the density hierarchy of the cement to reduce the chances of contamination. Additionally utilizing the early kick/loss detection system to instantly detect and minimize the losses during the job execution.

After Managed Pressure Cementing simulations a lighter MPC mud, 123pcf was proposed which in combination with the SBP and pump-rates will provide flexible EMW adjustments if required. It was planned to adjust the cementing pump-rates to minimize the high bottomhole frictions during the operations as dictated by the loss rates. The cement hardening time was pre-adjusted accordingly by adding the necessary retardants.

Throughout the cementing operation, the well was monitored closely using the early kick/loss detection system and suggested to reduce the ECD first by reducing the SBP and then by reducing the pump-rates. Enabled flexible EMW adjustment by fine tuning either SBP or pump-rates real-time as dictated by the losses. The ECD was managed real-time and almost instantly. Total 15-18bbls only was lost during entire cementing ensuring proper well integrity.

Minimizing losses during cementing operations is imperative for achieving adequate zonal isolation. The most common well integrity issues involve fluid migration through leakage pathways. Also, the dynamic pressure and temperature conditions during drilling and production exert a cyclic load on cured cement, and sometimes initiates cracks in the cement. These cracks then have the potential to act as pathways for fluid migration. Therefore avoiding troubles during primary cementing is essential for assuring well integrity.

This paper focuses on the optimization of well placement in the unconsolidated reservoir H in the South China Sea. The reservoir, located at a burial depth of 1050m, consists of three sand units with high-density interlayers and vertical heterogeneity. The lateral distribution of the top sand unit is uncertain due to wave transform. To effectively develop the reservoir, it is crucial to optimize horizontal well placement to increase exposure length of high-quality sand and distance from the water contact. This can be achieved by enhancing understanding of lateral distribution and vertical properties during drilling.

A combination of high-definition multi-layer reservoir mapping technology and a hybrid point-the-bit rotary steerable system (RSS) was introduced for the first time in the South China Sea. The reservoir mapping technology improved the ability to detect up to 10 layers and investigate depths up to 9 meters, providing visual display of sand unit distribution and the oil-water contact in this complex reservoir. The high dog-leg capability RSS navigated through larger hole sizes in unconsolidated sand, reducing the risk of borehole enlargement. An optimized hydraulic design with high drilling bit total flow area (TFA) and low flow rate bottom hole assembly (BHA) minimized borehole washout. These technologies allowed for real-time reservoir mapping data to be utilized in implementing and adjusting specific development strategies, ultimately improving reservoir productivity.

The well placement optimization involved implementing 7 horizontal wells in reservoir H with a total penetration of 2970 meters, achieving 100% contact rate in the high-quality reservoir. The oil water contact (OWC) was identified 8.3 meters below in the lower part of the structure, increasing the lifespan of the horizontal wells. In the middle part, the wells were placed in the high-quality sand layer, resulting in a reduction of remaining oil above. In the higher part, a stepped well path with proper distribution of the top two sand units increased production capacity by 30%. The total production of the project exceeded expectations by 10%. An anomalous, low resistance stripe was mapped along the well bore in the sweet zone, a mud invasion study found that was caused by the low resistivity mud filtrate rapidly formed a 1.2 m diameter flush zone in the stratum. The high-definition reservoir mapping results provided insight into the structure, allowing for modifications and improved understanding of lateral change in the formation.

The successful application of this integrated solution package confirms the feasibility of the integrated solution package in complex reservoirs with poor consolidation and provides valuable experience for future offshore oilfield applications.
