Authors: Priyadi Unggul , Achiria Siti
Published: November 2022

Bantul Regency have 92.05 hectare waqf land, spread over 2,959 locations. So far, 76 per cent of waqf land is used for mosques/musholla. At the same time, waqf land assets can be empowered to alleviate poverty. This study aims to: 1) optimise the utilization of waqf land assets through simulation of hydroponic cultivation and biofloc; 2) find a poverty alleviation model through the development of waqf land assets; 3) describe the implications of the implementation of the model. The method used in this research is descriptive qualitative, carried out by simulation and interviews with the community. Kapanewon Sedayu and Kapanewon Banguntapan are the main focus of the study and implementation of waqf land assets, considering that Bantul Regency had the highest number of poor people in 2020, as many as 138.066 people. The results show that based on the simulation, waqf land assets allow for community empowerment and the formulation of a waqf land asset management model through the Model of Islamic Social Entrepreneurship, and there are several implications for empowering the poor.

Published: November 2022

This paper focuses on the discourse of local religious traditions and its implication for the shifting religious authority among young Muslims in Banten and Yogyakarta dealing with their activity in social media (clicktivism). The existence of freedom of opinion and expression since the fall of the New Order and the widespread use of new media has had a significant influence on youth’s Muslimness, including the local Islamic tradition issues. In collecting data, this study utilized visual ethnography, observation, interview, and focus group discussion. While analyzing the collected data, we use Talal Asad’s Discursive Tradition. The research finds that the dissemination of information through social media was able to have a significant influence on the change in religious practices, especially in dealing with local religious (Islamic) traditions. This change is inseparable from the dynamic process of the discursive tradition of young Muslims on social media. Another implication of the process is a shift in religious authority from personal to impersonal.

Published: November 2022

Coronavirus disease since December 2019 has significantly affected millions of people. Given the effect this disease has on the pulmonary systems of humans, there is a need for chest radiographic imaging (CXR) for monitoring the disease and preventing further deaths. Several studies have been shown that Deep Learning models can achieve promising results for COVID-19 diagnosis towards the CXR perspective. However, this research field is at an initial stage since there is a limited number of large CXR repositories regarding COVID-19. In this study, five deep learning models were analyzed and evaluated with the aim of identifying COVID-19 from chest X-Ray images. More specifically, we utilized the ResNet50, ResNet101, DenseNet121, DenseNet169 and InceptionV3 using Transfer Learning. All models were trained and validated on the largest publicly available repository for COVID-19 CXR images. Furthermore, they were evaluated on unknown data as well, that was not used for training or validation, authenticating their performance, and clarifying their usage in a medical scenario. All models achieved satisfactory performance where ResNet101 was the superior model achieving 96% in Precision, Recall, and Accuracy. Our outcomes show the potential of deep learning models on COVID-19 medical offering a promising way for the deeper understanding of COVID-19.

Authors: Obinnaya Chikezie Victor Nwosu
Published: November 2022

The construction sector has begun to embrace the digital revolution, intending to improve efficiency. How, on the other hand, should the industry adopt digital tools? And how should the connection between humans and technology function? This study aims to shed light on how the construction sector may bridge the gap between AI deployments’s potential and realized advantages. This article presents research based on a comprehensive review of the literature, case studies of Speller Metcalfe, a design-build and refurbishment project in Malvern, England, Jacobsen Construction, a project digitizing the planning process in Salt Lake City, Utah, USA, and Menkes Development Inc., real-time visibility to construction site insights and data-driven decision-making in Toronto, Canada. The experiences gained via this study show that it is feasible to acquire expertise while adopting sophisticated technologies, such as artificial intelligence, by installing fundamental digital tools (AI). However, when it comes to AI, the level of trust between humans and machines will be the deciding element in its success. This article is a pioneering effort in examining the deployment of AI and how people and technology should interact. This study is limited to three case studies and three digital technologies. To further the study, it is suggested to debate the adaptation of AI on the user's premises, gather more empirical data, and examine case studies from different sectors.

Authors: Pérez-Rodríguez Mario , Santos-Rufo Antonio , López-Escudero Francisco Javier
Published: November 2022

It is known that high N doses, N/K imbalances, and frequent irrigation favor verticillium wilt. The influence of fertilization and its interaction with the frequency of irrigation on the development of Verticillium wilt of olive (VWO) has been evaluated. A split-split-plot design in microplots with two naturally infested soils of different texture was established for studying three fertilization treatments (NO3Ca, N-P-K and without fertilization), plus two irrigation frequencies (daily and deficit). The treatments were applied by means of fertigation, evaluating the susceptible cultivar Picual. Final disease incidence in plants subjected to NO3Ca-daily treatment was 100% regardless soil texture. However, final mortality in these plants was 37% and 85.2% in clay and sandy loam soils, respectively. As well, the area under the disease progress curve values were significantly higher (49.1%) in plants subjected to NO3Ca fertilization compared to those not fertilized or fertilized with N-P-K when plants grown in clay soil. This value in the sandy loam soil was significantly higher in the NO3Ca-daily irrigation treatment (94.3%), followed by the N-P-K-daily treatment (61.1%) which also was significantly higher than the unfertilized-daily, N-deficit and NPK-deficit treatments (37.8, 42.6 and 44.9 %, respectively). The plants submitted to unfertilized-deficit treatment reached the lowest value 9.6%. In this work it can be concluded that the application of fertilizer or the application of fertilizer with daily frequency irrigations in naturally infested soils increases the development of VWO in 'Picual'.

Published: November 2022

In recent years, Nigeria is witnessing increasing frequency of flood occurrence with devastating impact translating into significant loss of lives (in Nigeria, over 300 people died in September 2022) and properties. Addressing flood disaster requires holistic approach from policy and governance perspectives, integration of policies and programs and synergies between institutions. Using synergies and eliminating trade-offs, flood governance and policy coherence integrate all relevant policy fields and institutions to achieve common policy outcomes. The objective of this study is to examine and understand how flood governance and policy coherence are approached, as well as institutional design and implementation for coherence in Nigeria. The findings revealed that there is no single flood policy in Nigeria. Due to this, there is no focus and no defined objectives for flood governance, prevention, control, and management, and no imperative for the government to seek both short-term and long-term flood solutions. There is no synergy and coordination among institutions for flood governance in the country. Since the country established the federal ministry of environment in 1999, the environment, floods, and climate-related hazards were given less priority. State and local governments handle most flood disasters and emergencies. Federal assistance is provided, however, when flood disasters exceed the capabilities of local and state governments. This study recommends that across the country, flood policy needs to be designed, formulated, and implemented while assigning governance responsibility and decentralizing policy to state and local governments.

Published: November 2022

Carbon, which exists in large quantities on Earth, is a material with interesting properties, and many studies have been conducted since the past. In particular, nano-sized carbon allotropes are called carbon nanomaterials, and many studies are currently underway. Among them, carbon nanowall (CNW) is a structure in which graphene of sp2 bond is grown vertically, CNW have outstanding strength, can be highly electrically conducting or semiconducting, have a large specific surface area per unit mass. Electrical, chemical, physical properties of these CNW is modified by parameter such as surface density, height and thickness of it. Those have great effect on CNW and can be adjusted as growth interlayer. It was confirmed that the molybdenum disulfide (MoS2) interlayer synthesized by radio frequency (RF) magnetron sputtering altered the morphological characteristics such as the shaped edge of the CNW, the pores diameter and density. Through these studies, we confirmed the effect of MoS2 on the morphological characteristics of CNW. This opens the door to improving the performance of electrodes and devices.
The Principle "Like Begets Like" in Molecular and Algebraic-Matrix Genetics
Authors: Petoukhov Sergey
Published: November 2022

This article is devoted to results of in-depth analysis of the system of binary-oppositional structures in DNA n-plet alphabets and their algebraic-matrix representations. These results show that the molecular complementary replication of DNA strands is accompanied by the presence of an algebraic version of the principle "like begets like" in matrix representations of DNA alphabets having internal structures. This algebraic version is based on binary-oppositional structures in the genetic molecular system, which can be represented by bynary numbers and corresponding matrices of DNA alphabets. The received results allow thinking that the phenomenon "like begets like" (or a complementary replication in a wide sense) is a systemic in the genetic organization and is connected with algebraic features of biological organization. Correspondingly, the biological principle "like begets like" can be additionally modeled by algebraic-matrix methods and approaches. Such algebraic-matrix modeling of the genetic coding system gives new ways for studying and understanding a key role of the named principle in genetic and other inherited physiological complexes. The author believes that further study of the algebraic relationships of the genetic system and inherited physiological complexes will be increasingly revealing the key biological role of the ancient principle "like begets like" at different levels of biological organization.

Background: Implant surface topography is a key element in achieving osseointegration. Nanostructured surfaces have shown promising results in accelerating and improving bone healing around dental implants. The main objective of the present clinical and histological study is to compare, at 4 and 6 weeks, (w) bone-to-implant contact in implants having either machined surface (MAC), SLA medium roughness surface or a Nanostructured Calcium-Incorporated sur-face (XPEED®). Methods: 35 mini-implants with 3 different surface treatments (XPEED® (n=16) – SLA (n=13) – Machined (n=6), were placed in the posterior maxilla of 11 patients then, retrieved at either 4 or 6w in a randomized split-mouth study design. Results: The BIC rate measured at 4 and 6w respectively, was: 16.8 % (±5.0) and 29.0 % (±3.1) for MAC surface; 18.5 % (±2.3) and 33.7 % (±3.3) for SLA surface; 22.4 % (±1.3) and 38.6 % (±3.2) for XPEED® surface. In all types of in-vestigated surfaces, the time factor appeared to significantly increase the BIC rate (p < .05). XPEED® surface showed a significantly higher values when compared to both SLA and MAC values at 4w (p < .05). Also, at 6w, both roughened surfaces (SLA and XPEED® ) showed signifi-cantly higher values (p < .05) than turned surface (MAC). Conclusion: Nanostructured Calcium titanate coating is able to enhance bone deposition around implants at early healing stages.

The photocatalytic hydrogen evolution reaction (HER) by water splitting has been studied, using catalysts based on TiO2 nanowires (TiO2NWs), which were synthesized by a hydrothermal procedure. This nanomaterial was subsequently modified by incorporating different loadings of gold nanoparticles (AuNPs) on the surface, previously exfoliated MoS2 nanosheets, and CeO2 nanoparticles (CeO2NPs). These nanomaterials, as well as the different synthesized catalysts, were characterized by electron microscopy (HR-SEM and HR-TEM), XPS, XRD, Raman, Reflectance and BET surface area. HER studies were performed in aqueous solution, under irradiation at different wavelengths, which were selected through the appropriate use of optical filters. The results obtained show that there is a synergistic effect between the different nanomaterials of the catalysts. The specific area of the catalyst, and especially the increased loading of MoS2 and CeO2NPs in the catalyst substantially improved the H2 production. Recyclability studies showed only a decrease in activity of approx. 7% after 15 cycles of use, which opens many possibilities regarding the potential use and scaling of these heterostructures in photocatalytic production of H2 from water.

Published: November 2022

Abundant animal manure in livestock areas has the potential to be used as organic fertilizer which can restore soil fertility by turning it into compost and biochar. The goal of this study was to as-sess how well soil fertility and red chili yield might be increased by using biochar and poschar made from various animal wastes. In this investigation, a factorial pattern and randomized block design were used. The first factor was the biochar treatment type, which included no biochar, biochar made from cow manure, biochar made from goat manure, and biochar made from chicken manure. The second factor was the type of poschar, which included no poschar, poschar made from cow manure, poschar made from goat manure, and poschar made from chicken manure. The findings of this study suggest that using biochar in conjunction with poschar can significantly improve soil parameters such as soil water content, pH, EC, humic acid, fulvic acid, C, N, P, K, and CEC. Red chilies grow and yield more per hectare when different types of biochar and poschar are used. The use of biochar from cow manure together with poschar from chicken manure shows the best agronomic effectiveness.
A Review of Online Classification Performance in Motor Imagery-based Brain-Computer Interfaces for Neurorehabilitation
Authors: Vavoulis Athanasios , Figuereido Patricia , Vourvopoulos Athanasios
Published: November 2022

Motor imagery(MI)-based Brain-Computer Interfaces (BCI) have shown increased potential for the rehabilitation of stroke patients; nonetheless, their implementation in clinical practice has been restricted due to their low accuracy performance. To date, although a lot of research has been made in benchmarking and highlighting the most valuable classification algorithms in BCI configurations, most of them are using offline data and not from real BCI performance during the closed-loop (or online) sessions. Since rehabilitation training relies on the availability of an accurate feedback system, we surveyed articles of current and past EEG-based BCI frameworks who report the online classification of the movement of two upper limbs in both healthy volunteers and stroke patients. We found that the recently developed Deep Learning methods do not outperform the traditional machine learning algorithms. In addition, patients and healthy subjects exhibit similar classification accuracy in current BCI configurations. Lastly, in terms of neurofeedback modality, Functional Electrical Stimulation (FES) yielded the best performance compared to non-FES systems.

Lake Rawapening, Semarang Regency, Indonesia, has incorporated a holistic plan in its management practices. However, despite successful target achievements, some limitations remain that a review of its management plan is needed. This paper identifies and analyzes existing lake management strategies as a standard specifically in Lake Rawapening by exploring various literature, both legal frameworks and scholarly articles indexed in Google Scholar and published in Water by MDPI about lake management in many countries. There are two major types of lake management, namely pillar-based and object-based. While the former is the foundation of a conceptual paradigm that does not comprehensively consider the roles of finance and technology in the lake management, the latter indicates the objects to manage so as to create standards or benchmarks for the implementation of various programs. Overall, Lake Rawapening management should include more programs on erosion-sedimentation control and monitoring of operational performance using information systems.
Finansal Risklerin BİST 30 Endeksinde Yer Alan Firmaların Firma Değerleri Üzerindeki Etkisinin Araştırılması (2010-2020)
Authors: ABA ŞENBAYRAM Emel
Published: November 2022

Son yıllarda finansal piyasalarda görülen gelişme ve derinleşme finansal risklerin de çeşitlenmesine neden olmaktadır. Finansal riskler, firma değeri üzerinde ciddi etkilere sahiptir. Bu sebeple, şirketler firma değerini maksimize etmeyi amaçlarken, finansal yapılarını olumsuz etkileyecek risklerin etkisini de minimize etmeye çalışacaktır. Çalışmada finansal risklerin firma değeri üzerindeki olası etkilerinin panel veri analiziyle test edilmesi amaçlanmıştır. Bu amaç doğrultusunda 2010-2020 döneminde BİST 30 endeksinde yer alan 27 firma üzerinde inceleme yapılmıştır. Geri kalan 3 firmanın verilerine ulaşılamamış ve bu durum çalışmanın kısıtını oluşturmaktadır. Çalışma kapsamında oluşturulan modellerde firma değerini temsil için PP/DD ve Tobin Q, finansal riskler için ise kredi riski, kur (döviz) riski, likidite riski, faiz riski ve finansal kaldıraç oranı tercih edilmiştir. Yapılan analiz sonucunda kur riski ve kredi riskinin firma değerini negatif yönde etkilediği, likidite riskinin ise pozitif etkilediği sonucuna ulaşılmıştır. Likidite riskindeki olası bir birimlik artışın firma değerini 0,35 oranında arttırmaktadır. Risk ile getiri arasındaki doğru orantı bu durumun artı yönünü ifade etmektedir. Çalışma, firma değerinin finansal risklere olan hassasiyetinin incelendiği diğer çalışmalardan farklı olarak, 2010-2020 periyodunda post-covid19 ekonomi sürecini de kapsaması noktasında özgün olup, literatüre katkı sağlamaktadır.

The Relationship Between Intellectual Capital and Competitive Advantage: A Meta-Analysis Study
Authors: KILIÇLI Yasin
Published: November 2022

Purpose: The aim of this study is to examine the results of previous studies examining the relationship between intellectual capital (IC) and competitive advantage (CA) with a meta-analytic approach. Design/Methodology: Studies examining the relationship between IC and CA were reached by scanning a total of 14 national and international online academic databases. The Pearson correlation (r) coefficient was taken as a criterion in studies examining the relationship between IC and CA. Analyzes were performed using CMA software. A total of 15,625 samples from 71 studies were included in the meta-analysis process. In this study, the random effect model was used when interpreting the mean effect size. Findings: As a result of the study, it was understood that the calculated average effect size was 0.490 and this value corresponded to a high effect. This suggests that a higher IC is associated with a higher CA. This result supports common hypotheses and salient findings in the literature. Limitations: The meta-analysis applied in this study has some limitations due to its inherent shortcomings. Originality/Value: As a result of a comprehensive literature review, no studies examining the relationship between IC and CA with a meta-analytic approach were found. This study, which deals with the relationship between IC and CA with a meta-analytic approach for the first time, will provide a broader perspective on the literature in this field by calculating the average effect value between the mentioned variables over a large sample of 15.625.

Published: November 2022

Amaç: Günümüzde ekonomik büyüme ve kalkınmanın temel yapı taşı olan girişimcilik İslam açısından da önemlidir. Kur’ an-ı Kerim’ de insanoğluna yeryüzünü imar etme görevi yüklenerek insanoğlunun çalışması, geliştirmesi, üretmesi teşvik edilirken, Hz. Peygamber’de girişimciliği teşvik etmiş ve ahlaklı, cesur, risk alabilen tüccarı övmüştür. Fakat girişimci olmak kolay değildir ve birçok faktör girişimcilik isteğini etkilemektedir. Bu çalışmanın amacı girişimcilik ve finans dersleri alan ve finansal piyasalarda işlem yapan üniversite öğrencilerinin girişimci olma hakkında ne düşündüklerini ortaya çıkarmaktır.
Tasarım/Yöntem: Nitel araştırma yöntemiyle hazırlanmış çalışmada, Safranbolu Şefik Yılmaz Dizdar Meslek Yüksekokulu’nda girişimcilik ve finans dersleri alan ve finansal piyasalarda işlem yapan on üniversite öğrencisi ile yarı yapılandırılmış görüşme yapılarak elde edilen veriler yorumlanmıştır.
Bulgular: Genel olarak katılımcılar, finansal piyasalarda elde edilen gelirin sürekliliğinin olmadığını, kısa süre içinde kaybetme riskinin yüksek olduğunu, finansal piyasalara güvenmediklerini ifade etmişlerdir. Finansal piyasalarda kullanılan farklı enstrümanlar sayesinde risk dağılımı yapılabildiğini ve bu piyasaların daha hızlı ve kolay bir şekilde sermaye artışına olanak verdiğini, bu sayede sermayelerini arttırarak girişimci olmayı istediklerini ifade etmişlerdir. Katılımcılar, finansal piyasalardaki yatırımların İslami açıdan uygun olmadıklarını ifade etseler de yaptıkları işlemlerde bu hassasiyetlere dikkat etmedikleri görülmektedir.
Sınırlılıklar: Görüşmenin sadece Safranbolu Şefik Yılmaz Dizdar Meslek Yüksekokulu’nda girişimcilik ve finans dersleri alan ve finansal piyasalarda işlem yapan on üniversite öğrencisi ile yapılması araştırmanın sınırlılıklarıdır.
Özgünlük/Değer: Girişimcilik isteği üzerinde birçok çalışma yapılsa da finansal piyasaların girişimcilik isteğini ne şekilde etkilediği ile ilgili çalışmalara rastlanılmamış olması bu çalışmanın özgünlüğünü ortaya koymaktadır.

THE DENSITY FUNCTIONAL THEORY STUDY OF Li-ION DIFFUSION IN Na-DOPED Li4Ti5O12 AS LITHIUM-ION BATTERY ANODE
Authors: Fitriah Achda , Azhar Anugrah , Cahaya Adam Badra , Suprayoga Edi , Majidi Muhammad Aziz
Published: November 2022

Spinel phase lithium titanate (Li4Ti5O12 or LTO) has been studied as an alternative anode material with a “zero-strain” characteristic structure to improve safety, cycling stability, and rate performance. LTO offers stable Li-ion diffusion at a higher charge-discharge rate without noticeable structural change. However, LTO exhibits low electronic conductivity and low Li-ion diffusion compared to graphite-based anode materials, limiting its rate capability. In this study, we investigate the impact of Na atom doping on the diffusion rate in the Li4Ti5O12 (LTO) spinel phase using the density functional theory (DFT). Based on the nudged elastic band (NEB) calculation, we obtain the energy barrier values and each diffusion pathway, with barrier energy varying about 0.3~0.4 eV and affecting the value of the diffusion constant obtained. The study reveals the role of Na atom doping in the lithium-ion diffusion in NaxLi4-xTi5O12 for battery anode material.

Polymerase chain reaction (PCR) for the detection of nucleic acids is the gold standard test for the diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, there is the probability of false-negative results with this test, which poses a threat to public health. Here, we highlight some important factors that should be considered for reducing the false-negative results of the SARS-CoV-2 PCR test.

Published: November 2022

Investigating the genesis of geothermal resources requires a thorough understanding of the heat source mechanism, which is also a vital basis for the efficient exploration and utilization of geothermal resources. Situated in the eastern Himalayan syntax, western Sichuan is considered to be one of the main concentration regions of high-temperature geothermal resources in China. To date, various studies have been carried out to reveal the heat source and genesis of the abundant high-temperature resources in this area; however, studies on the contribution of the radioactive heat generated by the widely distributed granitoids to the high-temperature geothermal resources remain scarce. In order to resolve this knowledge gap, we attempted to obtain evidence from the geochemical data published in the literature in the past few decades. A total of 548 radiogenic heat production rate data were determined. The statistical data indicate that the average concentrations of the heat-producing elements U, Th, and K are 6.09±5.22 ppm, 26.74±16.78 ppm, and 3.51±0.82%, respectively. The calculated heat production values of the granitoids vary from 0.52 to 10.86 μW/m3, yielding an arithmetic average value of 3.74±2.15 μW/m3, which is higher than that of global Mesozoic–Cenozoic granites (3.09±1.62 μW/m3). Based on the heat production values, the capacity of the granitic batholiths to store heat was assessed, and the Dongcuo pluton was found to be the largest heat reservoir (382.88×1013 J/a). The distribution of the crustal heat flow was examined using the calculated heat production data and the stratigraphic structure obtained via deep seismic sounding in the study area. The results indicate that the crustal heat flow is 48.3–56.2 mW/m2, which is mainly contributed by the radioactive decay in the granitoids in the upper crust. The fact that it accounts for nearly half of the regional background heat flow indicates that the radiogenic heat from the granitoids is an important heat source for the formation of the thermal anomaly and the high-temperature geothermal resources in the study area. Thus, the results obtained in this study highlight the importance of the widely distributed granitoids to high-temperature geothermal resources in western Sichuan.
Valores, afinidades y redes sociales en el contexto universitario
Authors: García-López Irma Eugenia
Published: November 2022

Las instituciones son fundamentales para delimitar la sociedad, ya que permiten la legitimación de valores y principios desde las afinidades que puedan tener los individuos que la componen. Teniendo en cuenta lo anterior, en este trabajo se explora la hipótesis de que estudiantes universitarios con valores similares son afines entre sí. Para probarla se aplican dos instrumentos: primero, el Estudio de valores de Allport, Vernon y Lindzey, y segundo, una encuesta de percepción de afinidad de elaboración propia. Esto con la finalidad de explorar la formación de microsociedades, así como del rol que cumplen los valores e instituciones mediante un análisis de afinidad de valores en estudiantes universitarios. A partir de un procesamiento de modularidad se examinan las relaciones sociales de dos grupos de estudiantes que cursan una carrera universitaria y se compara su composición de valores. La evidencia permite concluir que no existe una composición de valores sustancialmente distinta en estudiantes, por lo que sus valores pueden surgir de un contexto más allá del universitario, por ejemplo, su localidad, región o un fenómeno generacional. Los resultados señalan que las afinidades de los participantes fueron recíprocas, indicando que las percepciones entre ellos coinciden, por lo que se abona a la noción de conciencias supraindividuales.

Despite its common use as an artificial lift method for heavy-oil developments, electrical-submersible-pump (ESP) system performance in high-viscosity applications is not fully understood. Failure to understand challenges to equipment performance in such conditions can lead to operational inefficiency and equipment failures. The complete paper presents results of single-phase and multiphase tests performed by researchers at the University of Campinas. It also presents operational data, lessons learned, and examples of failures gathered over 10 years of ESP operation in the Peregrino field, a highly viscous, heavy-oil field offshore Brazil operated by Equinor.

Peregrino Field

The field was discovered in 1994 in the southern part of the Campos Basin offshore Brazil. The discovery lies in shallow waters approximately 120 m deep in Block BM-C-7. Although a large amount of recoverable oil in place (300 million– 600 million bbl) was confirmed, the technology to properly develop the field was not available.

A detailed development plan was created to optimize Peregrino heavy-oil production while considering drainage strategy and well design. Recovery and production are maximized in Peregrino by extending the reservoir section length. As a result, every well in Peregrino is drilled with a long horizontal section inside the reservoir and completed with openhole gravel-pack lower completions. This strategy resulted in the longest wells in Brazil, with a record of 8613 m measured depth (MD) total length, with 2272 m MD in the horizontal section.

To improve the effectiveness of sand control and avoid solids production, gravel is pumped to fill the annular space between the 8½-in. openhole section and the 5½-in.-outer-diameter screens.

Inside the reservoir, water flows at a much higher velocity than viscous crude does. Therefore, inflow control devices are deployed in the lower completion to limit water flow into the wellbore at selected wells. To make gravel-pack operation feasible in such a configuration, sacrificial screens are installed in the bottom of the lower completion string.

An artificial lift method is required to produce the heavy and viscous oil from the field and maintain commercial rates when pressure support and production declines. ESPs proved to be the most-efficient method for this application.

Designing and delivering a successful completion in a subsea high-rate gas deepwater environment is a great challenge in upstream field development. The complete paper covers the sand-control design and execution techniques applied to four high-rate gas wells in the operator’s Block H development in the deepwater region of Sabah offshore Malaysia in 2020 and 2021.

Field Background

PTTEP’s Block H gas development is a multifield phased subsea development designed to deliver gas to Petronas’ floating liquefied natural gas (FLNG) project known as PFLNG2. The Block H field is in the South China Sea in water depths between 1150 and 1400 m. The first phase (Phase 1A) of the project was executed in four wells between the Rotan (three wells) and Buluh (one well) fields in the midsection of the Block H development.

The reservoirs completed in Phase 1A were deepwater slope turbidite sands deposited during the Late Miocene and contain high net-to-gross reservoirs. Based on evidence from sonic logs and rock-mechanics testing performed on rotary side-wall cores and fullbore cores, all targeted reservoirs required robust sand control.

Openhole gravel packing (OHGP) was chosen as the recommended sand-control technique for the high-rate gas application, and the four wells were drilled nearly vertically, with high water standoff height as a mitigation against early water coning. The drilling and completion operations were completed in a batch completion strategy in which all top holes were drilled to the top of the targeted reservoir, followed by the batch completion of all wells’ lower completion phase, then the batch upper completion and well cleanups. The wells were placed on production in Q1 2021 to PFLNG2, achieving the targeted rates per well of 80 MMscf/D solids-free.
Lagrangian Numerical Simulation of Proppant Transport in Channel Fracturing
Authors: Mao Shaowen , Zeng Junsheng , Wu Kan , Zhang Dongxiao
Published: November 2022

This paper focuses on the numerical simulation of particle (“proppant”) transport in channel fracturing, in which fiber-proppant fluid is pumped intermittently into hydraulic fractures, alternated with clean fluid pulses. The pulsed pumping protocol leads to heterogeneous/channelized proppant distribution in fractures, generating open flow channels with high conductivity. To understand the evolution of the channelized proppant distribution, we develop an efficient pseudo-3D multiphase particle-in-cell (P3D MP-PIC) method to simulate the proppant transport during the pumping process. Compared with the Eulerian-Eulerian (EE) models, the MP-PIC approach has higher accuracy in modeling particle-fluid and particle-particle interactions by tracing the particles in a Lagrangian fashion. Compared with the computational fluid dynamics-discrete element method (CFD-DEM), the MP-PIC method is more computationally efficient due to a parcel feature and the fast calculation of particle forces. Reduced from the 3D MP-PIC method, the P3D MP-PIC method has better computational efficiency and flexibility to couple with other subsurface processes (e.g., fracture propagation and fluid leakoff) while also achieving sufficient accuracy for engineering purposes. Due to the Eulerian-Lagrangian (EL) nature, the P3D MP-PIC method can track the trajectories of the fiber-proppant clusters whose effective viscosity and the settling velocity are determined based on the laboratory results. With an accurate description of fluid and particle dynamics, this work reveals the critical physical mechanisms of the proppant transport in channel fracturing: stable displacement and Saffman-Taylor (ST) instability. The alternate occurrence of these two mechanisms gives rise to the channelized proppant distribution. To investigate the influential factors of the channel patterns, we conduct parametric studies on the operational parameters, including injection rate, fiber concentration, and pulsing mode. The effect of fracture propagation and gravitational settling is also discussed in detail.
