MODELING OF PROSUMER LOAD PROFILES BASED ON BEHAVIORAL APPROACH
Authors: Kulapin Oleksandr , Makhotilo Kostiantyn
Published: May 2024

The article analyzes various approaches to the modeling of daily electricity load schedules and proposes a methodology for improving the "bottom-up" behavioral model of the load of household consumers. The method is based on averaging generated random load schedules for a given type of household on a particular day of the year. Averaging is carried out by season and length of daylight. Next, working days and weekends are distinguished in each interval. Despite some differences, this work does not separate holidays, Saturdays, and Sundays to avoid unnecessary details. The selected parameters for dividing the averaging intervals allow you to obtain a relatively compact set of model data and, at the same time, preserve the features of the load on different days of the year and hours of the day. Household load profiles with varying steps of day distribution and the main difference of such distribution are considered. Models that more accurately convey the sporadic nature of prosumer consumption compared to typical load schedules are built for two types of households. A detailed analysis of the averaged load graphs was carried out in comparison with the typical graph and the generated load graphs. Averaged load schedules are suitable for modeling the operating modes and control algorithms of the prosumer energy generation and storage system.
GUARANTEED ORIGIN OF ELECTRICITY IN THE LOCAL POWER SYSTEM WITH RENEWABLE ENERGY SOURCES
Authors: Lezhniuk Petro , Komar Vyacheslav , Hunko Iryna , Povstianko Kateryna
Published: May 2024

The article is focused on the development of a method for determining the part of electricity generated by renewable energy sources (RES) in the electricity flows in the branches of the electric grid. The method is based on a mathematical model of the electric grid, in which the coefficients of current distribution in the branches of the circuit from RES nodes and nodal voltages are used to determine the electricity flows in the branches of the electric grid. As a result, a matrix of power distribution coefficients of RES generation units to load nodes of the power grid is formed. This way, the component of the load power that depends on the power in the RES nodes is determined. The voltages used to form the RES power distribution matrix are determined based on the results of calculating the steady-state modes of the power grid or on the measurement data of the ACEMS.
Since the forming of local electric power systems (LES) based on RES is actual, the article considers LES as a balancing group within the electric power system (EPS), which can operate as an autonomous system according to certain conditions. It is shown that for this purpose, a RES reservation system should be created in the power system due to their dependence on natural conditions and, accordingly, the instability of their electricity generation. When a transmission system operates as part of an EPS, a general system reserve is usually used (mainly maneuverable capacities of thermal and hydroelectric power plants). In order for the LES can operate as an autonomous one, it is proposed to use other means of power reserve available today: electrochemical energy storage, hydrogen and biogas technologies. An effective way is to coordinate the schedules of RES generation in the LES with the load schedules of active consumers.
The example shows that in the case of a power deficit in the LES, RES located in the power grid can be used. The values of the necessary power at the LES connection node, power flows in the branches connecting the LES and RES grid, and power losses in them are determined by the offered method.

The Vectors of Economic Cooperation between Uzbekistan and China
Authors: Ionova E.
Published: May 2024

Located in the center of Central Asia, Uzbekistan has become an important link in Beijing’s transport and logistics projects developed within the framework of the Chinese “One Belt, One Road” initiative. After Sh.Mirziyoyev came to power in the republic in 2016, there was an intensification of cooperation between the two countries, which contributed to the transformation of China into the main trading partner and investor of Uzbekistan. Based on the results of meetings between the leaders of the People's Republic of China and the Republic of Uzbekistan in 2023-2024. agreements were concluded that significantly strengthened the Chinese presence in the Uzbek economy and humanitarian sphere. Currently, one of the priorities of economic cooperation between the two countries is the electric power industry, with a special role being given to China’s assistance in the development of “green energy” in Uzbekistan. The growing dependence on China, and not only economic, limits the multi-vector foreign policy that Uzbekistan and other Central Asian countries have proclaimed.

Authors: Alejo Ayodele Oluwole , Aigbavboa Clinton , Aghimien Douglas
Published: May 2024

Studies have demonstrated the critical role that safety plays in preserving favourable working conditions in the construction industry, which is necessary to accomplish goals. The aim of this research was to inform stakeholders in the construction industry in developing nations about the value of safety and possible strategies for influencing their opinions regarding safety protocols. The importance of safety to the construction sector, which is crucial to the advancement of the country, has also been emphasized. However, due to a lack of adequate safety understanding among stakeholders in the construction sector, the construction industry is characterized by a great deal of instability and hazard. To determine what factors, affect productive working conditions in the construction production, this study examined safety. A conceptual framework for safe working conditions in the construction sector was developed by considering several aspects, including the person dimension, environment factor, safety behaviour, organization features, technology, and incentives. It is now imperative to bring in these dimensions to improve the safe working conditions in the construction industry, particularly in the developing countries. By putting these safety factors into practice, the construction industry can reduce safety risks, lower the number of accidents and fatalities, cut expenses related to subpar safety performance, safeguard the reputation of construction companies, boost employee morale and satisfaction with their work, enhanced employee retention, reduced absenteeism, and enhanced sustainability goals. Additionally, the proposed conceptual framework is assured to be new and to be widely accepted in the developing nations. Based on this assumption the conceptual framework is designed.

Published: May 2024

Vaccines are one of the most effective medical interventions, playing a pivotal role in treating infectious diseases. Although traditional vaccines comprising of killed, inactivated, or live attenuated pathogens have resulted in protective immune responses, negative consequences of their administration have been well-appreciated. Modern vaccines have evolved to contain purified antigenic proteins, epitopes, or antigen-encoding mRNAs, rendering them relatively safe. However, reduced humoral and cellular responses pose major challenges to modern vaccine platforms. Protein nanoparticle (PNP)-based vaccines have garnered substantial interest in recent years for their ability to present repetitive array of antigens for improving immunogenicity and enhancing protective responses. Discovery and characterization of naturally occurring PNPs from various living organisms such as bacteria, archaea, viruses, insects, and eukaryotes, as well as computationally designed structures and approaches to link antigens to the PNPs have paved the way for unprecedented advances in the field of vaccine technology. In this review, we focus on some of the widely used naturally occurring and optimally designed PNPs for their suitability as promising vaccine platforms for displaying native-like antigens from viral pathogens for protective immune responses. Such platforms hold great promise in combating emerging and re-emerging infectious diseases and enhancing vaccine efficacy and safety.

Published: May 2024

Sinojackia Hu. comprises five to eight Chinese endemic species with high ornamental and medicinal value. However, the generic limits, interspecific relationships and evolutionary history of the genus remain unresolved. In this study, we newly sequenced and assembled three plastomes of S. oblongicarpa and compared them with those of the other congeneric species to explore the taxonomic delimitation of the species and the evolutionary history of the genus. Plastomes structure of Sinojackia species were extremely conserved in terms of number of genes, sequence length and GC content. Codon usage patterns revealed that natural selection may be the main factor shaping codon usage bias. Our phylogenetic tree shows that Sinojackia is monophyletic and can be divided into two clades. Sinojackia oblongicarpa as a distinct species is supported for it is distantly related to S. sarcocarpa. The evolutionary analysis of morphological features indicates that woody mesocarp is an ancestral feature, while mesocarp undeveloped, spongy and fleshy are the later derived. Sinojackia originated in Central-Southeast China during the early Miocene. In this period, it experienced elevated diversification and migrated from the Central-Southeast China to Hunan Province and Sichuan Province with the development of the Asian monsoon and East Asian flora. Sinojackia experienced elevated diversification at intraspecies levels that mainly occurred in the Quaternary. Glacial-interglacial interactions with the monsoon climate may provide favorable expansion conditions for Sinojackia on a small-scale.

Published: May 2024

Objective: To evaluate the direct costs of treating patients with neuromyelitis optica spectrum disorders (NMOSD) in outpatient care, from a hospital and Unified Health System (SUS) perspective. Methods: Observational study with data collection by microfunding, carried out with patients diagnosed with neuromyelitis optics, treated at a university hospital, in the city of Rio de Janeiro. Mann-Whitney tests were performed to measure cost differences between patient groups by disease severity and analysis perspective. Results: Nine individuals with a median age of 48 years (IQR 30 - 59 years) were included. The median total costs for patients with greater severity from the perspective of the SUS and the hospital were R$ 21,638.22 (IIQ: R$ 15,614.63; R$ 25,985.32) and R$ 32,094.11 (IIQ: R$ 25,610 .60; R$ 38,617.25) respectively. For patients with moderate severity the median was R$ 7,339.85 (IIQ: R$ 6,235.45; R$ 11,912.05) from the SUS perspective and R$ 11,505.80 (IIQ: R$ 7,339.85; R$ 22,424.76) from the perspective of the hospital, where the use of medications had a major impact. Conclusion: The main cost drivers were medicines, especially those used off-label, and procedures.
Nitrogen and Phosphorus Discharges from Cargo Ships’ Black and Grey Waters – Case of a Baltic Sea Port
Authors: Lappalainen Suvi-Tuuli , Tapaninen Ulla , Kotta Jonne
Published: May 2024

Shipping is a vital component of global trade. However, shipping activities have negative environmental impacts, including emissions to air and water. The Baltic Sea is severely affected by eutrophication, mainly due to nutrient inputs, especially nitrogen and phosphorus. The aim of this research is to quantify the nutrient content of black and grey water discharged from cargo ships in the Baltic Sea in order to assess their contribution to the total nutrient load. Specifically, the research examines the nitrogen and phosphorus loadings from ships calling the port of HaminaKotka and addresses key questions regarding nutrient generation, discharge proportions, emission shares by ship type and their importance compared to other sources. Using a methodology based on ship data and nutrient production estimates, the study found that 2545 cargo ships generated a total of 781 kg of nitrogen and 134 kg of phosphorus in their effluents during their voyages to the port in 2021. However, only a small fraction (0.5%) of the cargo ships discharged their wastewater at port reception facilities. The study concludes that, although nutrient discharges from cargo ships are relatively small compared to other nutrient sources, efforts to promote port reception or onboard treatment are important for environmental sustainability. Further research is recommended to assess the effectiveness of onboard treatment systems, the impact of other contaminants in wastewater and the development of port reception facilities to facilitate proper wastewater management in the maritime trade.

Published: May 2024

In recent years, long periods of drought and heat waves have become increasingly frequent, causing forest dieback phenomena that make stands more sensitive to biotic stressors. How trees may respond to extreme climatic events and which metabolites are involved under stress conditions is still not clear. In this study, we analysed by SPME how dieback (D) and non-dieback (ND) Hungarian oak trees from the San Paolo Albanese site respond to these climatic dynamics, in terms of volatile organic compounds (VOCs). For each group of trees, three wood samples were taken, each divided into four sub-samples with 5 growth rings, subjected to SPME and increase in basal area (BAI) analysis of the last 20 years. Dieback trees had a lower amount of leaves, and this condition may translate into less photosynthesis, less organic matter production and lower reserves of carbohydrates available for growth. Indeed, D trees showed lower radial increases and a lower content of aldehydes, terpenes, and fatty acids than ND trees, indicating a better health of ND trees compared to D trees. While D trees showed a reduction in terpenes, such as α-pinene, γ-eudesmol, and cyperene (with significant insecticidal activity), a reduction in aromatic aldehydes, such as furfural and 5-methylfurfural, and an increase in silanols (with antimicrobial function). Considering the different compounds’ contents between D and ND trees, our study could be useful for detecting bio-indicators to identify an early warning signal of dieback phenomena.
FPGA-based Accelerator Method for Edge Computing
Authors: Schulz Peter , Sleahtitchi Grigore
Published: May 2024

Edge computing helps radio-supported mobile systems to process computing tasks on the side of servers. The proximity to an edge computing node avoids excessive latencies, which benefits the calculation of real-time algorithms. Special computing needs arise because mobile systems are often so limited in weight and energy that they cannot carry powerful on-board computers. We propose the use of FPGA-based co-processors (FPGA: Field Programmable Gate Array) to handle computations in an edge node. The calculation of the Fast Fourier Transformation (FFT) will be presented as an example of a co-processor. The use of FPGA-based co-processors poses a particular challenge when a mobile system leaves its radio cell, and the computing context must be transferred to another edge node. The article first addresses specific edge computing requirements, such as case-by-case reconfiguration of computing hardware and the handover mechanism from one edge node to another. Using the example of an FPGA-based FFT co-processor, we describe its development, which was carried out under the condition that mobile clients can request different co-processors and that they can also change the edge node when changing the radio cell. The latter requires passing the co-processor context. For the FPGA, this means that the co-processor is part of a partially reconfigurable environment and must support the handover mechanisms in hardware. At the end we indicate the need for FPGA resources and compare this with alternative solutions.

Authors: Brizga Janis , Ulme Janis , Larsson Anna
Published: May 2024

This paper provides a comprehensive evaluation of the environmental impact of implementing the beverage container DRS on marine and coastal litter along the Latvian coastline. It incorporates data and insights from the assessment of deposit fractions litter in coastal areas during the post-season autumn period in three monitoring sessions from 2021 (before the introduction of the DRS in Latvia) to 2023 (post-introduction). In 2022, a 43% overall decrease in selected public coastal areas was observed, with significant reductions at 11 out of 17 sites. This positive trend continued in 2023, showcasing a further 22% decrease compared to 2022 and a substantial 56% decrease compared to 2021. The study delves into the specific impact on different material types of beverage containers, reporting significant decreases in plastic and aluminum litter fractions. While glass beverage container litter showed a smaller decrease, overall positive trends continued in 2023. However, the situation with aluminum cans remained challenging, especially in border areas with Lithuania and Estonia. The study emphasizes that beverage containers with identifiable deposit system labels constitute a minority of the total litter pressure, underscoring the need for ongoing efforts to address containers without deposit labels, particularly in specific border areas. The findings provide valuable insights into the effectiveness of the deposit system in mitigating coastal litter, contributing to sustainable waste management practices in Latvia.

Published: May 2024

In this study, a new nitrogen-enriched multiwall carbon nanotube is prepared and utilized to stabilize palladium species. After the characterization of this new composite, it was applied as a catalyst in the reduction of nitroarenes and hydrodesulfurization of dibenzothiophene. Using this newly established catalyst, a wide range of aromatic compounds were reduced to the corresponding amines under a very low amount of Pd (0.005 mol%) in short reaction times. Also, dibenzothiophene (a major pollutant in fuel oil) was very efficiently transformed using this catalyst. Its robustness was studied in the recycling process where, after 20 runs in the reduction of 4-nitrotoluene and 5 times in the desulfurization of dibenzothiophene, the activity of the catalyst remained intact. According to the E-factor calculations, the present Pd catalyst meets the standards of green chemistry.

Published: May 2024

Formidable and often seemingly insurmountable conceptual, technical, and methodological challenges hamper the measurement of oxidative stress in humans. For instance, fraught and flawed methods, such as the thiobarbituric acid reactive substances assay kits for lipid peroxidation, rate-limit progress. To advance translational redox research, we present ten comprehensive “cheat codes” for measuring oxidative stress in humans. The cheat codes include analytical approaches to assess reactive oxygen species, antioxidants, biomarkers of oxidative damage and redox regulation. They provide essential conceptual, technical, and methodological information inclusive of curated “do” and “don’t” guidelines. Given the biochemical complexity of oxidative stress, we present a research question-grounded decision tree guide for selecting the most appropriate cheat code (s) to implement in a prospective human experiment. Worked examples demonstrate the benefits of the decision tree-based cheat code selection tool. The ten cheat codes define an invaluable resource for measuring oxidative stress in humans.

Association between Mother's Educational Status And Home Literacy Environment With The Language Abilities Of Seven Year-Old Children: Path Analysis Evidence
Authors: Putri Anggi Resina , Susanti Nadya
Published: May 2024

Background: Factors that can influence the success of the educational process are family environmental factors, school environment, and community environment. The role of parents is to provide materials and help their children when they experience difficulties in the learning process. Language skills emerge in early childhood and are critical in promoting later literacy competencies, such as reading and writing. The period from birth to age 3 is critical for language development, as nearly all typically developing children acquire important language skills by age 3. During this period, children's home environment is especially important, as parents are the main providers of language input and support, allowing most children to acquire a basic foundation of language.

Methods: This study used a cross sectional study design, which was conducted in Surakarta City. A sample of 100 people was selected using a random sampling technique. Data collection was performed using a questionnaire and analyzed by path analysis.

Results: The direct relationship between expressive language abilities of children who have mothers with higher education is 2.2 units higher than children with mothers with low education (b=2.2; 95% CI= 0.9 to 3.5; p= 0.001). A high home literacy environment had a log odd of experiencing good expressive language skills of 2.04 units higher than children with a low home literacy environment (b=2.04; 95% CI= 0.7 to 3.3; p= 0.002). The indirect relationship between maternal higher education and expressive language abilities through the child's home literacy environment is statistically significant. Children who have mothers with higher education have log odd for high language expressive abilities of 2.8 units higher than children with mothers with low education (b=2.8; 95% CI= 1.7 to 3.9; p= <;0.001).  

Conclusion: A child's good expressive language abilities are influenced indirectly by the mother's high education through a high home literacy environment.

Published: May 2024

The presence of the Special Autonomy Law for the Province of Papua is a positive stimulant to bring about prosperity in the education sector. However, so far it has been found that the education sector is one of the sectors that has not run optimally. Special autonomy, which has not had a significant impact on the education sector, has created disparities in education between Papua Province and other regions in Indonesia. Based on this, this study seeks to examine the impact of the special autonomy policy on optimizing the education sector in Papua Province. This study uses a qualitative approach with a descriptive analysis model. The main data in this study comes from literature studies. The results of this study found that special autonomy has not had a significant impact on the people of Papua. This can be seen from the IPM of Papua Province which is at the bottom of the national standings. On the other side, the Papuan community's school enrollment rates and average length of schooling are still far below the national APS and RLS. This means that special autonomy has not been able to bring optimal impact on the education sector. There are several inhibiting factors, including the lack of political will from the Papua Provincial Government, the existence of corrupt practices, the lack of involvement of the Papuan People's Council in evaluating the allocation of autonomy funds in particular, including in evaluating the allocation of funds for the education sector and due to the contours of the area being quite large and difficult.

Published: May 2024

The purpose of this study is to evaluate the performance of bureaucratic reform in making changes to the system of government administration in the aspects of institutional (organization), management (business process), and human resources of the apparatus. Various studies show that local government bureaucratic reform tends to be slow due to various obstacles experienced, one of which is in Tuban Regency. Bureaucratic reform in the Tuban Regency Government is implemented based on eight areas of change to improve the quality of public services. However, there are still many obstacles faced, including the quality of apparatus resources, low accountability, and inadequate electronic-based government capabilities. This research method uses a qualitative method with a document study approach and uses secondary data analysis techniques, namely researchers using materials sourced from books, agency reports, and the internet to obtain data from relevant sources. The results showed that the bureaucratic reform in Tuban district has carried out performance evaluations based on the assessment of each program's achievement. In the aspect of building a clean and accountable bureaucracy, the SAKIP index is still low and experiencing a decline and the Anti-Corruption Behavior Index is low and still below the national average. The aspect of bureaucratic capability is assessed based on the SPBE index which is only 50% running and the ASN professionalism index is still in the low classification. Third, the aspect of excellent service is seen from the low public service index, which shows that there is still a gap between service recipients and the reality of services provided to the community. There needs to be a holistic improvement in bureaucratic reform efforts to realize a world-class government that is clean and accountable, a capable bureaucracy, and a bureaucracy that can provide excellent service.

Published: May 2024

This research aims to describe the synergy between stakeholders to accelerate the reduction of stunting rates in Surakarta. The background is that the target of zero stunting in Surakarta in 2022 has not been successful because stunting was still detected in Surakarta in February 2022. The Government has extended its zero stunting target to 2024. Of course, synergy is needed because the problem of stunting is not just a problem for one party. The type of research is descriptive qualitative. Researchers used Doctoroff's (1997) synergy theory, namely effective communication, fast feedback, trust, and creativity. Data sources were obtained from primary data in the form of interviews determined through purposive sampling and secondary data using documents, archives, news, and so on. Data collection uses interview and documentation techniques. Data validity using source triangulation Data analysis techniques use the theory of Miles, Huberman & Saldana (2014), including data condensation, data display, and conclusions drawing. The research results show that synergy between stakeholders is still not successful because all parameters have not been fulfilled properly. Miscommunication is still found between the Health Service, DP3AP2KB, and the society. Apart from that, communication between the Health Service and PT Solo Abadi Indonesia is still not effective. The feedback provided by the Health Service was also considered to be insufficiently fast. This shows a lack of trust from PT Solo Abadi Indonesia to the Health Service. On the creativity parameter, new innovation output was also not demonstrated by BAPPEDA, DP3AP2KB, and the Health Service.

Authors: Marselinus Ruben Zefanya , Wijaya Komang Adi Sastra
Published: May 2024

Innovation in the public sector is an important element in improving and enhancing higher quality public services. Public sector tends to have problems with things such as efficiency, effectivity, corruption, slow responds and many others. The DKI Jakarta Government has made innovations in the public sector, namely the JAKI application which integrates various public services and public information into one application. The problem found in the JAKI application is the low adoption of innovations or the use of JAKI application innovations by the community, coupled with a decrease in the number of users in 2023. This research used qualitative methods, data obtained by interview, observation and documentation. The purpose of this research is to identify which indicators of Rogers innovation attributes cause the low adoption rate of JAKI application. The results of this study indicate that JAKI innovation has fulfilled the innovation attributes of relative advantage, compatibility, and observability. In the complexity indicator, the JAKI application is still constrained by the application that still occurs errors. Furthermore, in terms of trialability indicator, many people do not know the JAKI application and have never used or tried the JAKI application. In addition, the JAKI application was launched without prior testing and lack of direct socialization. Therefore, it can be concluded that the adoption of JAKI application is lacking due to complexity and trialability indicator.

This contribution analyses the role played by the mechanical properties of a decollément shale layer in the evolution of the Mexican Fold and Thrust Belt (MFTB). The mobility of overpressured shales can accommodate large strains by grain-scale plastic mechanisms, and affect the folding and thrusting styles of the overburden. Research on shale deformation mechanisms is necessary to improve the knowledge of these processes and their influence on the structural style of fold and thrust belts. The ductile behavior of rocks involving grain-scale plasticity was documented in the Jurassic Santiago shale sequence using geological mapping, microstructural observations on thin-oriented sections, and scanning electron microscopy (SEM) imaging. Structural styles such as detachment folding, fault-bend folding, and shale-cored fold-thrusts were observed at the regional scale. At the outcrop scale, the shale developed strong foliation and pencil cleavage, with immersed packstone boudins. Observed structures include thrusting, soft and open folds, and buckle folding. In thin section, the ductile textures include a strong penetrative foliation with lenticular and wavy-parallel laminae composed of carbonates, ribbons of reoriented clays and organic matter (clay+OM), s-c structures, porphyroblasts microtextures, development of oblique cleavage concerning folded foliation (crenulation cleavage), and carbonates dissolution. The Santiago shale shows also evidence of brittle deformation including calcite-filled fractures and cataclastic gouges. X-ray diffraction (XRD) analysis of the clay size fraction suggests that the authigenic calcareous shale was deformed in conditions of the deep diagenetic zone (between 100 and 200°C) and fluid overpressure (>70 MPa). The results help to improve the understanding of ductile microstructure and its role in shale deformation cretaceous cover, promoting the formation of localized fault propagation folds in the overburden. This study aims to open new perspectives in the kinematics and rheology interpretations for this sector of the MFTB, highlighting the role of the décollement layers during the progression of the orogen.

Carbon capture and storage (CCS) is one of the primary mechanisms being studied and implemented globally toward the push for a healthier planet. Dynamic modeling of carbon dioxide (CO2) storage in depleted gas reservoirs requires a great amount of integration between various domains, including reservoir engineering, production engineering, geomechanics, well integrity, and geology. In this paper we will highlight various important areas of integration that are necessary to consider while conducting a dynamic modeling study for CO2 storage.

Multidomain integration is required at various stages of the dynamic modeling of CO2 storage in depleted gas reservoirs. To decide the suitable boundary conditions, it is important that geological aspects of the structure are fully integrated. Thorough cyclic integration between the reservoir, production engineering, and well integrity is needed to ensure that realistic operational conditions for the injection well are computed and considered during dynamic modeling.

In this paper we will show, with the help of a recent case study, the methodology and importance of multidomain integration for accurately modeling the CO2 storage in a depleted gas reservoir. Integration between geology and reservoir engineering is crucial while selecting the CO2 storage sites as well as while deciding the applicable boundary conditions. Geomechanics plays a vital role in defining the fracture gradient for each well for different formations. This fracture gradient is an important value to consider while selecting the bottomhole injection pressure limits for the dynamic simulation. Similarly, a close integration between reservoir engineering, production engineering, and well integrity is crucial to establish valid operational conditions, pressure, and temperature, which will enable the required injection rates to be injected without encroaching toward freezing conditions and hydrate formation, among others.

Several innovative integration workflows were created during this study. These include integration of geology and reservoir engineering for boundary conditions selection, integration of geomechanics and dynamic modeling, and integration of production, reservoir engineering and well integrity for selection of valid operational conditions.

Mature oil fields tend to face drastic changes at both levels of production and operational efficiency leading to increasing demand of manpower & logistics as well as decreasing trend of equipment uptime that results in associated production deferrals.

A key to sustainability of mature oil fields is to ensure high levels of utilization of existing resources and defy the progressive logistical demand to maintain profitability margins at maximum levels. such objectives can be approached by transformation to digital oil field.

Digital oilfield incorporates data acquisition through installation of necessary sensors & meters, data management & analytics, remote monitoring, remote control & automated workflow.

Gulf of Suez Is one of the mature oil basins that started oil production in mid-1960s and suffers from the same challenges facing mature oil fields. A vision of going digital was adopted and various digitalization projects are being deployed to allow remote monitoring & Control of gas lifted wells. which suggest several values ;

Productivity: Digital oil field supported production optimization by optimum lift gas utilization giving more room for reactivation of shut in wells. Accessibility to all wells allows proper production deferral management during any production upset. Innovative data driven diagnostic tools supports troubleshooting and setting priorities of interventions.

Operational Efficiency: harmony of production system can be improved dramatically with remote monitoring and control resulting in higher uptime of key equipment such as gas lift modules. logistics and manpower is a major part of operating cost of any mature field, incorporating remote monitoring and control will decrease the need of helicopter & boats trips to manual investigate production drops, efficient distribution of lift gas resulted in less gas lift demand & lower load on compression facilities.

Profitability: Imperative impact of digital oil field hitting two birds with one stone; production & cost optimization will boost the profitability margin.

the progressive implementation of digital oilfield in the subject asset succeeded to achieve 3% production increase, alleviate the demand of logistics and manpower, decrease the gas lift demand and managed to stop one gas lift module which had positive impact on asset profitability.

Digital oil field is a good investment for green fields but it is a vital investment for mature field and a key enabler for business sustainability.
