Published: July 2020

<p>Cultural values have a wide influence on international business management and its related activities. In people's daily living environment, due to the different culture and education people receive, the growing environment is different, so it can be divided into different groups, resulting in the relationship between each different cultural groups more and more estranged. If there is no correct sense of management, it is difficult to have close communication, and even there will be barriers in communication. This article mainly analyzes the cross-cultural issues, expounds the cultural factors in international business management, enumerates the cultural differences in international business management, and makes an in-depth analysis of the role of cultural values in international business management and related activities. The purpose is to strengthen the management awareness of relevant managers in cross-cultural management.</p>
O JUDEU NA LITERATURA PARA CRIANÇAS E JOVENS. UMA LEITURA COM HISTÓRIA.
Authors: D'Alte Pedro 
Published: July 2020

A diegese d’O caderno do avô Heinrich dá a conhecer uma personagem que migra por força da perseguição cultural e religiosa. Heinrich refugia-se, nos últimos anos da sua vida, em Portugal. A referência narrativa desperta, desde logo, a curiosidade pela possível relação entre a fé judaica e o espaço geográfico português. Por outro lado, sendo tão breve, a mesma oculta todo o tecido histórico que se entretece entre ‘Portugal’ e o ‘Judaísmo’2. Porque merecedor de atenção académica, o trabalho que aqui se apresenta pretende ler os imagótipos judaicos presentes em narrativas para jovens - em articulação com a historiografia portuguesa -, com o intuito de relembrar e de tornar visível este rico património histórico.
O SOBRENATURAL COMO EXPRESSÃO DA MEMÓRIA EM “A CHAVE NA PORTA” E “QUE SE CHAMA SOLIDÃO” DE LYGIA FAGUNDES TELLES
Authors: De Sousa Maria Vilani 
Published: July 2020

Lygia Fagundes Telles é considerada um dos nomes mais significativos da moderna ficção do Brasil. O diferencial da escritora reside na competência em mesclar diferentes temporalidades. Nisso, este trabalho analisa o viés do fantástico nos contos A chave na porta e Que se chama solidão, referenciando a construção social das memórias nas narrativas, objetivando compreender o uso do fantástico para expressar este processo memorialístico das protagonistas femininas de ambos os contos. O estudo apoia-se nas pesquisas sobre o fantástico em Todorov (1992) e, quanto ao campo do imaginário, se utiliza da ideia de Gilbert Durand (1993), dialogando, ainda, com Freud (1986) e Maurice Hawlbacks (2006).

Published: July 2020

Blind and visually impaired citizens are a special category of people with disabilities. According to the World Health Organization data, there are about 39 million blind people around the world and 246 million people have very low vision. The formation of a barrier-free environment in the field of social services, culture, education, employment is the most important task for representatives of federal and regional authorities, ministries and departments. Institutions of various profiles are doing great work on socio cultural rehabilitation of persons with restricted health abilities and on ensuring them equal opportunities with other citizens to participate in social life. Library services for people with complete or partial loss of vision are part of the social rehabilitation system. People of this category are provided with information by special libraries for the blind and visually impaired as well as by the network of state and municipal libraries. In the context of globalization, there rises the question of integrating special libraries for the blind and publicly accessible libraries into the united system for to provide disabled people with information services. The article gives a brief characteristic of publications devoted to library services for blind and visually impaired citizens. Library specialists actively discuss ways of uniting resources and promoting services for people with total or partial loss of vision for to raise effectiveness in solving tasks of adaptation for this group of inhabitants. Such system could support people, having restrictions on vision, in full realization of their rights and liberties, create conditions for raising culture of consumption of products and social sphere services.
TYPOLOGY OF INTELLIGENCE AND LIBRARY LOGO
Authors: Sokolov A. V. 
Published: July 2020

Intelligence is understood as a means of mental activity, that is, a means of generating, storing, understanding, transforming thoughts in a special intelligible space of the noosphere. Three types of intellects are distinguished depending on the thinking subject: Intelligence A is an individual lively wit of a member of a society, which is in his mind; Intelligence B is a social logos, which is the core of abstract thought and speech sphere of public consciousness (logosphere) and includes the BB Bibliologo as one of its particular types; Intelligence C is an artificial intelligence that exists in a digital virtual reality (computer space and time). Intelligence A is a natural one, operating with symbols (speech and images) in a psychical human world; Intelligence B is artificial, operating with cultural codes in a social environment; Intelligence C is artificial, operating with digital signals in an electronic virtual environment. Two ideological problems are examined: firstly, the problem of the intelligences A, B, C dynamics of development in biological and historical time; secondly, the problem of interaction of various intelligences in the modern society logo sphere. The conclusion that digital culture must be balanced by humanitarian (humanistic) culture, the bearer of which is book cultural heritage, is made. For this, each Russian library should be a center of Russian culture, combining three types of intelligences: 1) library logo; 2) artificial intelligence of free access; 3) lively intelligence of a library team. The educational mission of Library Logos is to use their intellectual potential for to bring to senses (familiarize with the mind) the population of Russia. Moreover, it is desirable that our politicians should comprehend that the library is the humanistic stronghold of the nation, and digitalization (informatization, automation) is an auxiliary tool to strengthen book culture as the basic value of Russia.
Successful Strategy for Waterflooding Project Implementation in an Extra Heavy Oil Field

Published: July 2020

Abstract
Chichimene is the third most important field of Colombia, with an original oil in place of USD 3.1 million barrels, producing an extra heavy oil of around 8 API, characterized by high viscosity and reduced mobility. The estimated recovery factor was around 3%, and the reservoir pressure was declining drastically; because of this, it was necessary to urgently implement an enhanced oil recovery project, since without immediate intervention, the reservoir and field production would be seriously affected.
A thorough screening process was performed among diverse EOR options, and waterflooding was selected as the best alternative for maintaining reservoir pressure and increasing the recovery factor. The main challenge was to have a rapid implementation for the entire reservoir, considering that this region has reported community issues derived mainly from water management disagreements and inconformity with stringent labor requirements. Additionally, lengthy environmental permits and high deployment expenditures were factors that affected field development plans.
The research of an effective technology for the field-specific conditions and a low deployment cost indicated dumpflood as the best alternative, since it enabled injection from a deeper water formation to an upper production target zone through a smart BHA, substantially reducing injection facilities investment and operational costs. Time savings were identified, eliminating additional requirements for environmental permits. The main concern was that this technology has never been implemented for extra heavy oils.
Simulations in a steady state simulator validated the feasibility of the dumpflood technique in the field. Models of the production and injection zones evidenced the pressure needs and the necessary BHA adjustments to meet the target rates and to define the completion model with the specific equipment to perform the operation.
Implementation started in the South West area of the field and was deployed with three waterflooding patterns in a record time of three months. After nine months of operation, the reservoir pressure augmented in the surrounding wells, and the failure indicator of the electrical submersible pumps was reduced by a factor of 20%. As a major milestone, the average field production climbed by approximately 10,000 bbl/d. Considering the successful results, the project was extended to 20 waterflooding patterns in other areas of the field, the waterflooding project was approved and sanctioned one year after the pilot startup and therefore over 20,000 barrels of oil equivalent were incorporated to the proved reserve balance.
A New Approach for Geomechanical Evaluations with Modified Pickett Plots
Authors: Malaieri Mohammadreza , Matoorian Raya , Aguilera Roberto 
Published: July 2020

Abstract
A Pickett plot is a powerful graphical technique for petrophysical analysis of well logs, which was developed initially to represent Archie's equation visually. Pickett plots rely on pattern recognition on a log-log scale observable on a set of porosities and the corresponding true resistivities taken from well logs. The analyses of these plots have been used in the past, primarily for the determination of water saturation. However, throughout the past years, Pickett plots have been extended and modified for the evaluation of other reservoir parameters of interest, such as permeability, process/delivery speed, bulk volume water, and pore throat apertures.
In some recent works, applications of the Pickett plot have been extended from representing only a snapshot on time to describing and explaining several millions of years of burial, compaction, maturation trajectories, and petroleum generation. The word ‘petroleum’ as used in this paper includes oil, gas, and natural gas liquids.
In this study, the Pickett plot has been modified and extended to include geomechanical parameters such as Vp/Vs, Poisson's ratio, Young's modulus, Shear modulus, bulk modulus, friction angle and Unconfined Compressive Strength (UCS). A better understanding of these parameters helps to minimize risks associated with drilling, stimulation, and wellbore stability problems. Geomechanical characterization is vital to understand fracture creation and propagation. Hydraulic fractures are more likely to be generated in brittle zones with lower tensile strength, lesser Poison's ratio, and higher Young's modulus.
Mechanical properties are usually measured in laboratory experiments such as Triaxial Compression Tests carried out on core samples. But cores are not always available for testing; therefore, the original contribution of this paper is the construction of a modified Pickett plot that can help to perform quick and reasonable evaluations of geomechanical properties while at the same time carrying out standard petrophysical analysis of petroleum reservoirs. This type of integrated petrophysical-geomechanical interpretation on a single plot is not currently available in the literature.
Ultra-High Density Oil-Based Drilling Fluids and its Applications in Ultra-Deep Petroleum Systems
Authors: Li Qinghui , Li Shaoxuan 
Published: July 2020

Abstract
Global energy demand has driven petroleum industry to develop hydrocarbon resources from extremely harsh formations. Ultra-high density drilling fluids are critical to successful drilling and completion practices in all of these wells. In this paper, potential weighting materials were systematically evaluated and screened to accomplish an ultra-high density oil-based drilling fluid system (19.62 to 22.12lb/gal) aimed to utilize in ultra HPHT conditions (&gt;30000psi and &gt;410°F). Potential high-density weighting materials were evaluated. Properties (pure density, particle size/distribution, surface area etc.) were evaluated and compared. Special treatment was conducted to optimize properties of weighting materials. HPHT filtration tests under static and dynamic conditions were conducted at higher than 410°F and 300 psi. Real cores with an average porosity of 19% and an average permeability of 50 md were used in the filtration tests. Rheological properties, sag tendency, the volume of filtrate, and the filtrate cake characterization was measured before and after heating at 410°F for 16 hours.
Results revealed that ultra-micro manganese and ilmenite complex after suitable surface treatment could act as an ideal weighting material than ultra-pure barite or other materials, which could fail in rheology and sag measurement with such high temperature and density. Viscosity and filtration analysis confirmed the stability and reliability of this novel ultra-high density oil-based drilling fluid.
This study developed a challenged drilling fluid system under critical conditions, as well as established a systematical laboratory evaluation and screening procedure of weighting materials and contributed recommendations on how to utilize it in the fields.
Migration of Liquid Hydrocarbons in Organic-Rich Reservoirs Based on Geochemical and Well Log Analysis Explained with the use of New Practical Model
Authors: Piedrahita Jaime , Aguilera Roberto 
Published: July 2020

Abstract
This paper develops a new conceptual liquid-hydrocarbons migration model for practical application in organic-rich mudstone reservoirs. The method uses a combination of well log formation evaluation data, micro-resistivity image logs, nuclear magnetic resonance, and geochemical measurements obtained from either drill-cuttings or core data.
In the method proposed in this paper, organic matter (OM) geochemical indicators from organic petrography (thin sections), vitrinite reflectance, TOC from Leco analyzer, Rock-Eval pyrolysis including S1, S2, and Tmax are integrated with triple-combo and NMR logs so that both lean and organic-rich intervals can be identified. The addition of natural fracture intensity to the interpretation package makes the methodology quite unique. After applying cut-offs for each individual parameter, two types of migrations are identified that could take place in these source-rock reservoirs: primary and secondary migration.
The model is applied in a wildcat vertical well that penetrated several stacked organic-rich mudstones. The formation gross thickness of the evaluated section is around of 2800 ft-TVD divided into six main formations composed mainly by siliciclastic minerals with a moderate carbonate content, and low presence of clay minerals. The source-rock reservoirs penetrated by the well can be sub-divided into (1) naturally-fractured, (2) tight and (3) hybrid reservoirs. Reservoirs in sub-division (1) are very important because they might be able to produce oil without the need of hydraulic fracturing. Reservoirs in sub-division (2) have natural fractures but their scale is very small to allow any oil production. Consequently, they must always be hydraulically fractured. Reservoirs in sub-division (3) might or might not need hydraulic fracturing.
Intervals with high organic carbon content, S1, oil saturation index, and geochemical index but low natural fracture intensity indicate tight reservoirs, and they likely correspond to the hydrocarbon source that charged the juxtaposed naturally fractured or hybrid reservoirs. On the other hand, several intervals that present poor TOC, are highly brittle and naturally-fractured, and are connected with tight organic-rich intervals. Thus, the potential of these naturally fractured intervals to produce oil is quite significant.
The novelty of the method developed in this paper permits analyzing primary and secondary migration in the source rock. The method further permits identifying the type of reservoir (naturally fractured, tight and/or hybrid) penetrated by the exploratory wells. This allows ranking the most prospective intervals as well as optimum landing zones for future horizontal or geosteered wells to be drilled in neighboring areas.
An Open-Source Enabled Drilling Simulation Consortium for Academic and Commercial Applications
Authors: Losoya Enrique Zarate , Gildin Eduardo , Noynaert Samuel F , Medina-Zetina Zenon , Crain Tim , Stewart Shaun , Hicks Jimmy 
Published: July 2020

Abstract
Simulation of drilling processes involves the seamless integration of strongly coupled physics, numeric, and economic models. Operators desire advanced drilling simulation software that can mimic reality and yet be practical for daily operations. At the same time, academic researchers are devoting time and effort to develop robust and accurate models of every module of an integrated drilling environment but are challenged with translating their original contributions into the operational setting. We seek to solve both of these issues through a distinctive collaboration consortium based on an open-source paradigm. We describe and propose an advanced drilling simulation developed through a joint industry consortium at Texas A&M University. The simulator provides free access to sophisticated and reliable drilling dynamics solvers. This includes drill string dynamics, torque and drag analysis, geologic modeling, hydraulics, and wellbore pressure modeling, visualization, and operator interfaces. The simulator is written in C++ and is built on top of high-performance open source libraries that leverages parallel computing, GPU acceleration, multibody, and computational fluid dynamics solvers as well as other tools (see figure for further details). We will assist industry and academic users to employ our open-source tool. In addition, we will help said parties further develop our framework into proprietary and protected business software via the addition of custom functionality. The simulator core was successfully developed and has been used to model horizontal drilling, while providing near real-time performance. The framework has been used in several applications successfully, including modeling shallow horizontal jetting, rock drilling, and steering; as well as reconstructing spatial data from high fidelity downhole signals for borehole evaluation, and the development of improved downhole navigation algorithms. We believe that a collaborative development effort between academia and industry will bring solutions to complex modeling needs faster and more economically than any individual endeavor. To this end, the authors will also show how one can partner with Texas A&M University to obtain access to the open-source enabled drilling simulation framework and platform to collaborate, improve and create solutions for new and existing problems.
New Method for Overburden Modeling to Improve Geopressures Calculations
Authors: Velázquez-Cruz David , Espinosa-Castañeda Gustavo , Morquecho-Robles Adalberto 
Published: July 2020

Abstract
This paper showing that using rock-density measurement from well-logs affect the calculation of overburden stress because "environmental effects" caused by borehole conditions, overpressures, gas content, high mud filtrates, formation fluid saturation and rock mineralogy. Those effects influence the rock-density measurements and consequently both the overburden stress and geopressures computations; furthermore, the lack of rock-density well-logs in the first drilling stages also affect the overburden stress determinations. However, we consider that the most important bias-effect in the overburden stress calculation is that the overburden must be determined exclusively using the rock-density due to normal compaction of sediments. Hence, we are proposing a new method and model to compute the overburden stress that utilize a power law approach to reproduce rock density values instead to use log-density measurements. The new method is based on the theory of consolidation of clays described by Terzagui and Peck in 1948 which considers that rock-porosity reduction because of compaction when sediments burial increases. This rock-porosity reduction or rock-density increment can be modeled by a power law approach and use its results to calculate overburden instead rock-density measurements from well-logs. Here, we describe how establish the normal compaction trend for rock-density and its integration into overburden equation. This modified overburden model is showed and some examples are presented to permit readers to use the method with their own data. The examples compare the overburden stress calculated with new method against those using rock-density measurements from well-logs. The results show better overburden estimations using the power law model and how the use of rock-density readings from well-logs impact in the geopressures results because mislead of the overburden stress. The results allow to conclude that the overburden stress must be calculated using rock-density due to normal compaction of sediments and avoid the use of density-log readings that are influenced by "borehole environmental effects".
