Authors: Gutiérrez García Ana , Landeros Velazquez María
Published: November 2020

The objective of the present investigation was to explore the levels of academic self-efficacy and their relationship with performance, anxiety and depression in a sample of emerging university adults. 114 students between 17 and 30 years of age (SD = 2.12), answered the in the Academic Behavior Self-efficacy Scale, the Diagnostic Questionnaire for Depressive Disorders and an Anxiety Inventory. For academic performance, the average grade for high school education, the university entrance exam and the first semester of university were considered. The analysis of the measurement of the levels of each of these variables and their correlation, indicated that the respondents who had low academic self-efficacy when entering university, had the lowest academic performance during high school and a high level of anxiety upon entering university without symptoms of depression.

Evaluación y medición de la expansión territorial de la minería informal en la cuenca alta del Ramis, Puno, Perú, usando imágenes satelitales
Authors: Giraldo Malca Ulises Francisco , Vasquez Ruesta Pedro Gonzalo
Published: November 2020

La presente investigación aborda la problemática ambiental que genera la explotación de oro de la minería informal en tres sectores de la cuenca alta del río Ramis (CARR), la cual constituye una de las actividades económicas más impactantes al medio ambiente y a la sociedad en el Perú. A pesar de existir normas específicas orientadas a su formalización y regulación, sus efectos negativos se han expandido e incrementado considerablemente en los últimos doce años. Precisamente, las tecnologías de teledetección constituyen herramientas eficientes, que pueden ser de muy bajo costo, útiles para evaluar y analizar la problemática ambiental de un área tan extensa como el ámbito de interés (perteneciente a la hoya hidrográfica del lago Titicaca), de modo que se logró ver la evolución que ha tenido la minería aurífera en esta zona mediante la cuantificación de la superficie que presentó cambios en el uso del suelo para el periodo comprendido entre 1984 y 2015, usando imágenes de satélite multiespectral Landsat.Los resultados del análisis de veintiséis imágenes satelitales diferentes, para detectar las superficies que tuvieron un cambio de uso de suelos, se comparan cronológicamente con la ocurrencia de hechos sociales, políticos y económicos, como la cotización internacional diaria del oro, manifestaciones del conflicto socio ambiental o acciones de intervención del gobierno, factores que influyeron en la expansión territorial o estancamiento de las actividades de minería  informal en la zona, así como la eficacia que tuvo las acciones tomadas por parte de las autoridades competentes para su control o mitigación.

Published: November 2020

En la presente investigación buscamos desarrollar una Mediateca Pública para todos los usuarios del distrito de Independencia. Realizamos un estudio profundo del lugar, de los usuarios y de proyectos referenciales, los cuales nos han ayudado a proyectar un edificio que resuelva la problemática principal de este distrito. Independencia es el centro económico de Lima Norte. Sin embargo, la mayoría de personas a cargo de las microempresas del distrito no tienen una educación completa ni una visión global del campo al que se dedican. Esta situación constituye la problemática principal de este distrito. Por tanto, la respuesta a esta problemática es poder brindar al usuario una opción donde pueda obtener información acreditada de manera fácil, rápida y práctica, incluso usando el edificio como una máquina informativa en sí misma, para que los peatones sean educados con tan solo pasar por dentro o fuera del edificio. Colocamos la mediateca en la intersección de dos avenidas principales del distrito: Túpac Amaru e Izaguirre, en la intersección de tres zonificaciones (vivienda, comercio y educación) para que la mediateca tenga mayor alcance a mayor variedad de usuarios. Buscamos brindar un espacio público donde los diferentes usuarios interactúen con la intención de que el edificio se compenetre con una relación de ida y vuelta con su entorno inmediato. Asimismo, buscamos brindar un servicio comunitario al contexto inmediato, ya que dentro del radio de influencia tenemos muchas instituciones educativas que no cuentan con espacios adecuados para estudiar.

Authors:   ,   Universidad Peruana de Ciencias Aplicadas (UPC), La Rosa Cuya José Manuel
Published: November 2020

El proyecto de tesis consiste en una reacción ante la falta de organización de los clubes peruanos y la ausencia, hasta hace poco, de un plan de la Federación Peruana de Fútbol que busque la fomentación de las divisiones menores en nuestro medio. Se ha comprobado a través de resultados internacionales (selecciones y clubes) que existe una necesidad de un centro que permita que jóvenes futbolistas pueden crecer en todo los aspectos de sus vidas (deportivamente, académicamente y personalmente) para ser profesionales en un futuro. El proyecto arquitectónico se ubica en la Av. Mariano Pastor Sevilla en Villa el Salvador, en donde este se basa en el concepto del proceso formativo del futbolista y físicamente se colocan tres volúmenes claramente definidos que representan cada etapa de la formación del joven. El bloque de profesionales aprovecha la pendiente del terreno para ubicarse por encima del bloque de juveniles y representar el objetivo final de cada usuario del proyecto de manera concreta. El emplazamiento de la arquitectura se rige a la disposición de las canchas (las cuales están condicionadas por el eje Norte – Sur) y las decisiones urbanas tomadas para incorporar a la comunidad al proyecto y paisajismo. El resultado final es una arquitectura horizontal, con estética industrial representativa de Villa el Salvador y que se integra a la topografía local mediante plataformas y ejes urbanos que generan perspectivas interesantes para usuarios y vecinos.

Children’s Engagement with Exploitative Work in Dhaka, Bangladesh
Authors: Roelen Keetie , Paul Sukanta , Howard Neil , Mathur Vibhor
Published: November 2020

Despite decades of interventions aiming to reduce child labour, children’s engagement with exploitative work remains widespread, particularly in South Asia. Emerging evidence about cash transfer programmes point towards their potential for reducing children’s engagement with work, but knowledge is scarce in terms of their impact on exploitative work and in urban settings. One component of the CLARISSA programme is to trial an innovative ‘cash plus’ intervention and to learn about its potential for reducing children’s harmful and hazardous work in two slum areas in Dhaka, Bangladesh. This Working Paper presents findings from a small-scale qualitative study that was undertaken in late 2019, aiming to inform the design of the cash plus intervention. Findings point towards the potential for cash transfers to reduce the need for children to engage in exploitative work and highlight key considerations for design and delivery, including mode and frequency of delivery and engagement with local leaders and community representatives.

Sentences of аlternative motivation in Russian and English
Authors:   Dubna State University, Ragozina Inna F.
Published: November 2020

The present paper is devoted to the sentences of alternative motivation in Russian and English. They are constructions with the conjunctions а то, а не то, иначе and their English equivalents otherwise, or, or else. The direct object of the study is those structures in which there is a verb-predicate in the Subjunctive mood in the second clause. The following thesis has been proved: such structures contain a compressed unreal-conditional sentence so that they represent three-part formations: an indicative part, an unreal implicit condition represented by a conjunction and a non-indicative part expressing the result of the condition. Denotative-semantic criterion has helped to state that a semantic space of the sentences of alternative motivation consists of at least three individual meanings: proof by contradiction, causal explanation and teleological (purposive) explanation. The first two senses come from an unreal-conditional sentence and the third one is a specific one only for the sentences of alternative motivation. The formulas of interpretation allowing determining these senses have been developed; their surface indicators in both languages have been defined: markers of negation (explicit and implicit), the mode of appraisive forming of an indicative part, etc. The examples of the corpus have been borrowed from English literature of different epochs in comparison with their literary translation.
Metonymic trigger in euphemy
Authors:   Moscow State Linguistic University, Porokhnitskaya Lydia V.
Published: November 2020

The paper examines the specific role that metonymic concepts play in the semantics of euphemisms. It is shown that metonymic concepts are basic structures that underlie metaphoric concepts the meaning of euphemisms is modelled on. Such metonymic conceptual structures (metonymic triggers) constitute patterns that may generate numerous metaphoric concepts of different degree of complexity. The findings of our research testify to the fact that it is possible to single out two ways of the metonymic conceptual actualization within the framework of metaphoric concepts. In the first case gradual metaphoric complication of the metonymic concept results in the weakening of the euphemistic potential of a word or a phrase. This transformation may be accompanied by the specification of the conceptual focus though in most cases the focus is preserved. In the second case metaphoric complication of a simple metonymic concept triggers the enhancing of the euphemistic potential of a language unit. As a result, it may function in a wider range of communicative situations. The research shows that the two models are actualized differently in classical euphemy and in modern politically correct discourse. Whereas in traditional euphemistic spheres both models are common, in politically correct discourse it is the first pattern that is especially productive.
Semiotics of “pandemic” discourse: “newspeak” of quarantine era
Authors:   Pavlodar State Pedagogical University, Temirgazina Zifa K. , Luczyk Malgorzata ,   Zelenogursk University
Published: November 2020

The article examines the specifics of semiosis, which results in signs for the nomination of new realities in the context of a coronavirus pandemic. The study shows that “Newspeak” of the quarantine era is formed during the work process of two main mechanisms: the extension of the already existing meanings of word signs in the language (war, front line, enemy, embrasure, paranoia, bacchanalia) and production of words according to standard derivational models, activating in the minds of native speakers in case of need (covidnyi, covidarii, dokarantinnyi, poslekarantinnyi, karantinit’). Using these mechanisms, native speakers act in accordance with the principle of language economy, relying on their existing knowledge and stereotypes of language production to learn new experiences. The third way for new words to appear is through borrowing, which takes a less significant place in creating “Newspeak” of the pandemic era (lockdown, sanitizer). The “pandemic” discourse is characterized by such connotative signifiers as negative evaluation and emotionality, globalization of perception, uncontrollability, and unpredictability. They determine a person's choice to connect language signs and new objects during semiosis.

On the originality of elegiac motives in A.P. Chekhov’s short stories and novels
Authors:   Ivanovo State University, Kapustin Nikolay V.
Published: November 2020

The article deals with the comparison of the motive of remembering typical for the genre of elegy on the whole and those works of A.P. Chekhov which have elegiac motives. The analysis of the topic shows that the motive of remembering in Checkov’s works has been essentially transformed. If we take the romantic elegy (very typical for the works of B. Zhukovsky) the Past plays the greatest role. For Chekhov at the end of 1880s axiological status of the Past is less worthy (“Verochka”, “Mrs. NN’s Narration”, “The Steppe”). According to Chekhov focusing on the Past ignoring the Present can cause the spiritual crisis. We can observe it in the Story “Verochka”. Another difference: Chekhov himself and some of his literary characters realize that human conscience can idealize the Past thus distorting the reality. At last in V. Zhukovsky’s Elegies memory of the Past is the determining motive in life. It smoothes the contrast between the Present and the Past. For Chekhov’s personages warm memory of the Past is just a moment. It does not help to improve the present situation.

Authors: Duarte Henrique , Oliveira Esmael Alves de
Published: November 2020

O presente artigo visa refletir sobre o modo como os indígenas são descritos e narrados pela imprensa na cidade de Dourados, Mato Grosso do Sul, MS. Em específico no jornal O Progresso, que tem relevante circulação e divulgação na região. O estado de exceção retrata os discursos que matam ligado ao sentido de extermínio, formulado por Agamben no termo “estado de exceção”. Como podemos entender a categorização do indígena para e na sociedade a partir da mídia? É com esta indagação que os artigos jornalísticos publicados nos cadernos policiais das edições foram analisados. Partindo da produção dos discursos expressos pelo jornal em questão, a partir do conceito de representações sociais, buscamos evidenciar as teias de significados presentes na narrativa jornalística e que têm servido para construir e naturalizar violências e subalternidades em relação às populações indígenas do estado. Assim, a partir de pesquisa documental, em diálogo com o campo das Ciências Sociais, em especial com a Sociologia, buscou-se compreender os papéis que esses discursos noticiosos apresentam, constroem e reiteram.
Direitos constitucionais e povos indígenas: apontamentos sobre a disputa pela efetivação do direito fundamental às suas terras tradicionais
Authors: Aguilera Urquiza Antonio Hilario , Santos Anderson
Published: November 2020

O presente trabalho tem por objetivo analisar os direitos fundamentais dos povos indígenas conquistados com a promulgação da Constituição Federal de 1988, seguindo a ordem internacional de proteção de Direitos Humanos e o rompimento de paradigmas inaugurados pela Convenção 169 da Organização Internacional do Trabalho (OIT). Com efeito, as efetivações dos direitos indígenas perpassam várias nuances, não sendo possível aqui abordá-las por completo. Assim, este trabalho se restringirá a analisar as disputas políticas que envolvem a organização do Estado brasileiro, protagonizadas por interesses de setores anti-indígenas, conforme consta no relatório do Conselho Indigenista Missionário (Cimi) de 2018, que visam, especificamente, em relação aos arts. 231 e 232 da Constituição Federal de 1988, à extinção e/ou modificação de direitos no texto constitucional. Trata-se de pesquisa com enfoque sociojurídico, com método indutivo, com base na análise de dados, pesquisa bibliográfica, sítios da rede mundial de computadores, relatórios de organizações e produções científicas.

Effect of an Illegal Open Dump in an Urban Forest on Landscape Appreciation
Authors: Bielinis Ernest , Janeczko Emilia , Janeczko Krzysztof , Bielinis Lidia
Published: November 2020

Rubbish in a forest environment is a great threat to this ecosystem, but this threat may also apply to the lost benefits for visitors to the forest. Previous studies proved that forest areas have a positive effect on obtaining psychological relaxation in the people visiting them. However, it was not known whether this restorative experience could be disturbed in any way by the presence of an open dump in the forest. To check how the presence of a landfill affects the visitors, an experiment was planned in which the respondents observed a forest area with a landfill and a forest landscape without a landfill for 15 minutes (control). The respondents then assessed the landscape using the semantic differential method and the Perceived Restorativeness Scale (PRS). An analysis of these observations showed that the presence of a landfill in the forest significantly changed the appreciation of the landscape by the respondents, the values of positive experiences decreased, and the negative experiences increased. Restorativeness was also reduced. Based on the results, it can be concluded that the presence of garbage in the forest may interrupt the restorative experience of its visitors.

Impact of the COVID-19 Lockdown on the Electricity System of Great Britain: A Study on Energy Demand, Generation, Pricing and Grid Stability
Authors: Kirli Desen , Parzen Maximilian , Kiprakis Aristides
Published: November 2020

The outbreak of SARS-COV-2 disease 2019 (COVID-19) abruptly changed the patterns in electricity consumption, challenging the system operations of forecasting and balancing supply and demand. This is due to the mitigation measures that include lockdown and Work from Home (WFH), which decreased the aggregated demand and remarkably altered its profile. Here, we characterise these changes with various quantitative markers and compare it with pre-COVID-19 business-as-usual data using Great Britain (GB) as a case study. The ripple effects on the generation portfolio, system frequency, forecasting accuracy and imbalance pricing are also analysed. An energy data extraction and pre-processing pipeline that can be used in a variety of similar studies is also presented. Analysis of the GB demand data during the March 2020 lockdown indicates that a shift to WFH will result to a net benefit for flexible stakeholders, such as consumer on variable tariffs. Furthermore, the analysis illustrates a need for faster and more frequent balancing actions, as a result of the increased share of renewable energy in the generation mix. This new equilibrium of energy demand and supply will require a redesign of the existing balancing mechanisms as well as the longer-term power system planning strategies.
Novel Human-in-the-Loop (HIL) Simulation Method to Study Synthetic Agents and Standardize Human-Machine Teams (HMT)

Published: November 2020

This paper presents a multi-year research study conducted at the University of Toledo, aimed at improving human-machine teaming (HMT) methods and technologies. With the incorporation of artificial intelligence (AI) into 21st-century machines, collaboration between humans and machines has become highly complicated for real-time applications. The penetration of intelligent and synthetic assistants (IA/SA) in virtually every field has opened a path for the new area of HMT. When it comes to crucial tasks such as patient treatment and care, defense, and industrial production, the use of non-standardized HMT technologies may pose a risk to human lives as well as up to billions of taxpayer dollars. A thorough literature survey revealed that there are not many established standards or benchmarks for HMT. In this paper, we aim to address the lack of HMT design and development standards. We propose a method to design an HMT based on a generalized architecture. This design includes the development of an intelligent collaborative system and human team. Followed by processes and metrics to test and validate the proposed model, we present a novel human-in-the-loop (HIL) simulation method using two controlled HMT scenarios; first, emergency care provider (ECP) training, and second, patient treatment by an experienced medic. Both scenarios include humans processing visual data and performing actions that represent real-world applications while responding to a Voice-Based Synthetic Assistant (VBSA) as a collaborator that keeps track of actions. As part of these HMT simulation studies, the impact of each parameter related to machines, humans, and HMT (such as errors made by humans and by the VBSA) is presented from the perspective of performance, rules, roles, and operation limitations. In addition, based on the analysis of results from two case studies, we presented guidelines for designing future HMT. Our conclusions indicate that the proposed HIL can be used to perform standardization studies in the pursuit of developing techniques for benchmarking HMT that can be used in critical situations.
Decoherence and Recurrences in a Large Ferromagnetic $F = 1$ Spinor Bose-Einstein Condensate
Authors: Romero-Rochin Victor , Sandoval-Santana Juan Carlos , Paredes Rosario
Published: November 2020

Decoherence with recurrences appear in the dynamics of the one-body density matrix of an $F = 1$ spinor Bose-Einstein condensate, initially prepared in coherent states, in the presence of an external uniform magnetic field and within the single mode approximation. The phenomenon emerges as a many-body effect of the interplay of the quadratic Zeeman effect, that breaks the rotational symmetry, and the spin-spin interactions. By performing full quantum diagonalizations very accurate time evolution of large condensates are analyzed, leading to heuristic analytic expressions for the time dependence of the density matrix, in the weak and strong interacting regimes. We are able to find accurate analytical expressions for both the decoherence and the recurrence times, in terms of the number of atoms and strength parameters, that show remarkable differences depending on the strength of the spin-spin interactions. We discuss the nature of these limits in the light of the thermodynamic limit.

Published: November 2020

Aruk is part of Sebunga Village, Sajingan Besar District, Sambas Regency, west-Kalimantan. The Aruk region is directly adjacent to the country of Malaysia and developed into a Pos Lintas Batas Negara (PLBN). The existence of PLBN provides easy access that affects not only the economic and social culture, but also has an impact on the physical changes of buildings in this area. This research was conducted to recognize the physical characteristics of buildings, especially residential buildings located in the Aruk border area. 74 selected buildings were collected through observation which was strengthened by interviews with users. The variables in this study are the function, use of materials and visual form of the building's appearance. Data were analyzed to see the closeness of building characteristics, especially with the year of establishment so as to conclude the character of residential buildings in these locations. The results of the analysis show that buildings that built earlier periode in the Aruk use material that are easily found around locations, especially wood, and have a more complex appearance than the buildings after. These characteristics tend to change in line with the development of this area and increasingly easy access to the region.
Penerapan Arsitektur Tradisional Bali pada Perancangan Teater Kesenian Kontemporer di Badung
Authors: Saputra Alan Darma
Published: November 2020

Bali is a gathering of tourist who come from all over the country. Because of this, a mixture of cultures emerged on the island ranging from lifestyles such as clothing, language, food to architecture, so that over time Balinese architecture became faded. To prevent this, it is necessary to preserve traditional Balinese architecture by applying traditional forms of architecture to new buildings, especially the theater (as buildings that become icons of Balinese culture). The theory chosen was traditional Balinese architecture, contemporary theater provisions and neo-vernacular architecture. The method used to trace the case is descriptive qualitative by taking important aspects in neo-vernacular architecture as a meeting point between traditional Balinese architecture and neo-vernacular, then these aspects are used as a benchmark in the design transformation from what was originally a small span building to a wide span with a theater function. The study results obtained are guidelines and examples of the application of Asta Kosala-kosali in contemporary theater on spatial, roof, body and foot structures of Balinese architecture and the combination of Balinese architectural tectonics in contemporary art theater. This journal has a high urgency because at present there are many functions that require wide-span buildings, so that Balinese architecture can be applied to buildings without eliminating the culture or noble values in it.

Cultural heritage areas in the form of historic urban villages are part of the country's wealth that deserves to be preserved. The value and authenticity of settlements is the focus of conservation measures. Protocol Hoi Ana in 2009 explained the dimensions of cultural heritage. This dimension is divided into two: first, dimensions that are visible, in the form of visual, visible, building material, location, place settings, and others. Second, the dimensions of values contained in cultural heritage, in the form of history, spirit of place and others. The authenticity and whereabouts of historic villages in a city have so far decreased in number and seem to disappear with frequent cases of fires that damage this cultural heritage area. From the data collected, there are various causes of fires in the historic urban village. The main focus is related to the low level of public awareness, among others: negligence due to the fall of candles, transformer explosions, excessive use of currents, low awareness of the causes of electricity theft practices which often lead to short circuits which cause fires that cause casualties, damage to urban areas and historical buildings in it. The historic city village is a property of the nation and state. The community has the same responsibility in a community to save and preserve it. This paper reviews various literature studies related to the role of the community in preventing the danger of fire in cultural heritage areas that have been home to tens or even hundreds of years. With the existence of knowledge and sense of ownership by the community, it is hoped that fire prevention management in the historic township can be applied and its sustainability carried out.
Sludge Formation in Sandstone Reservoir-Advancement in Characterizations and Removal Process
Authors: Al-Taq Ali , Al-Moajil Abdullah , Aldarweesh Sajjad , Alsalem Ali
Published: November 2020

Oil-based mud is commonly used in drilling of the pay zones in sandstone formations as a less/non damaging fluid. Oil-based mud typically contain emulsifier, viscosifer and other additives including polymer blend and calcium carbonate to serve different functions. Presence of emulsifier may increase emulsion tendency upon interaction with downhole environment. The resulting emulsion might be tight to an extent that a thick sludge is formed which can impair well productivity. Identification of the sludge material will help in development of an effective chemical treatment to remove formation damage and restore well productivity.

In this study, an extensive laboratory work was conducted to explore potential interactions of an oil-based mud with different contaminants encountered in downhole environment. A typical sludge sample was characterized using different analytical techniques including solvent extraction, XRD, TGA, ICP and viscosity. The results showed that the sludge sample contained calcium carbonate, dolomite quartz as the main components in the inorganic phase while the organic phase include polymers and oil. The source of calcium carbonate might the drilling additives while the source of quartz is the formation. Analysis of supernatants generated from solubility tests conducted for the sludge sample revealed in addition to the high amount of calcium presence of iron in considerable amount (nearly 1,000 mg/L). Interaction of ferric chloride, quartz with an invert-emulsion mud was investigated. A significant increase in viscosity was observed upon incorporation of these contaminates with the mud sample. This paper presents in detail the results of interactions of iron ions, quartz, and pipe dope. It also examined several chemical formulations for removal of sludge formed and filtercake.

Banyu Urip, which is the highest producing oil facility in Indonesia with 220 kbd, generates up to 40 MW electrical power to maintain production. Any power blackout results in significant production upset including high flaring. This is exacerbated by usually extended recovery time post power blackout due to complex electrical distribution system. The Banyu Urip facility has experienced production loss due to historical power blackout events, most recently in 2019. This paper provides a case study on optimizing load shedding and gas turbine fuel control system, which could serve as learning for other power generation facilities in various industries for designing a robust blackout prevention system.

An integrated blackout prevention system comprises of Electrical Control and Monitoring System (ECMS) as primary load shedding, Gas Turbine Generator (GTG) temperature peaking control, and backup load shedding by under-frequency protection relay is designed. All these load shedding layer of protection cover multiple blackout prevention scenarios or protection system element failure such as GTG trip, overloading, and ECMS failure.

Multiple parameter analysis and simulation were performed to determine characteristic of each protection layer. Turbine exhaust temperature response, load, fuel supply, as well as generator frequency are all taken into consideration for the integration of blackout protection layer.

Key factor for the seamless integration is timeline of each element to work and for backup element to activate. All must be done within GTG overload capability corridor.

ECMS load shedding system is put as the frontline to prevent overload in case GTG trip. As the backup layer, protective relay will enable under-frequency load shedding upon overload and GTG slowdown. GTG temperature peaking control and under-frequency set point are properly designed to ensure that the under-frequency relay is operating.

After implementing these optimizations, load shedding is proven to work very effectively and there has been some GTG trip events without blackout nor significant production impact.

Evaluation of system performance continues as Banyu Urip Central Processing Facility (CPF) operates. The results will be critical for reliability improvement as well as production continuity assurance. In other words, this also provides a best practice for blackout mitigation to optimize successful power generation facility operation.

The Ordovician fractured carbonate reservoir in the Shunbei field is buried ~7300m below ground level and has presented great challenges for the drilling of extra deep, deviated development wells. Borehole instability-related drilling problems including pipe stuck, pack-off, and mud losses have been experienced frequently during drilling, with many wells being sidetracked three or four times before reaching the target. To understand the failure mechanism and optimize the drilling design to mitigate the drilling risk has become crucial for the field development.

As the basis of the investigation, detailed geomechanical modelling was conducted for a selected area with the most representative drilling problems. Laboratory core tests, wireline logs, image data and drilling experiences were used to build geomechanical models characterizing the in situ stress, pore pressure and rock mechanical properties in both the overburden and reservoir sections. Stress-induced borehole failures observed in the image logs were analysed to help diagnose the failure mechanisms together with the cavings recovered from the problematic wells, which provided significant insights into the likely nature of instability problems in the wells.

The geomechanical modelling from a series of wells revealed that the stress magnitudes in the selected area vary based on the structural location. The wells near the major fault system appear to be in a normal faulting stress regime in the Ordovician reservoir, while the wells nearby the secondary fault system are in a strike-slip faulting stress regime. Different stress regimes and horizontal stress anisotropies have resulted in different behaviors during drilling, with breakouts seen in some vertical wells while not in other vertical wells despite using similar mud weights. during drilling. The variable stress conditions plus the highly developed fractures have caused serious borehole collapse in some wells, but reasonably good hole condition in other wells. Wells using higher mud weight are not necessarily the ones having fewer drilling problems. Although the complex lithology, great depth, and unpredictable distribution of intrusive rocks has complicated the drilling problems, a proper definition of suitable mud weight to control borehole collapse and understanding of the natural fractures might play a bigger role in maintaining borehole stability and mitigating drilling risk.

A good understanding of the stress condition and rock mechanical properties appears to be helpful in defining the proper mud weights and optimizing other drilling parameters to help mitigate the complex drilling problems encountered during drilling in the Shunbei field. However, additional work on the fracture distribution and trend of stress change in the field might be required to help investigate the problem further.
Operational Considerations During Gas-Condensate Well Start-Up
Authors: Chan Cynthia , Zhang Jeff
Published: November 2020

Gas hydrates are ice-like crystals formed by gas and water molecules under low temperature and high-pressure conditions. Avoiding the formation of hydrate plugs is one of the critical tasks that continuously challenges oil and gas operators, especially as oil and gas operations move into deepwater reserves. Common mitigation measures for hydrate formation and plugging include the traditional control methods of injecting thermodynamic inhibitor that assure the operational conditions are outside the hydrate risk region. However, inhibitor injection rates are typically designed based on the worst operating conditions (i.e., maximum pressure and minimum temperature) with significant safety margin. During transient operation such as well start-up, the risk of hydrate formation is higher compared to normal operation and requires significant volume of hydrate inhibitor. This paper presents two case studies that integrate field experience into design to optimize design scenarios for hydrate prevention during gas-condensate well start-up. The first case study shows how the shutdown and start-up scenarios typically considered for design are benchmarked with historical data to avoid unrealistic over-conservatism when creating design scenarios for well start-up. By benchmarking with historical data, the MEG injection rate is able to be reduced by 30%, which in turn increases economic feasibility of the offshore gas-condensate field development. In the second case study, the hydrate inhibitor rate was reduced by 50% by adopting current field practice into design and using state-of-the-art hydrate kinetic modelling to determine the likelihood of hydrate formation and the transportability of hydrates in flowlines. Combining field experience into design reduces constraint to the hydrate inhibitor distribution system, optimizes usage of topside facilities and aids in the development of hydrate management strategy for the field as a whole.
