The article highlights the issues of increasing the production efficiency of the operational facility reserves at one of the large oil fields at the final stage of development. On the example of one of the facilities, a methodological approach to the development analysis is considered, which allows determining the optimal strategy for further reserves development, the effectiveness of which is subsequently confirmed by the successful geological and technical measures implementation. Based on the results of lateral horizontal trunks sealing, the assumption of residual reserves localization in the inter-well space associated with the historical fund from operation retirement with a decrease of the gas lift operation technology efficiency due to an increase in waterlogging is confirmed. It is established that for the conditions considered, the well grid density and the multiplicity of the formation pore volume flushing have a direct impact on the production efficiency. The first drilling results confirmed the sufficient predictive capacity of the complex analysis and allowed to resume the substantive drilling program at the facility with reserves of more than 85%, the main grid of wells of which was fully implemented more than 40 years ago. Keywords: mature fields; oil field development; reserves development; development system.

Pore channels distribution in reservoir by size largely determines such filtration parameters as absolute and phase permeability, as well as the residual oil saturation of the productive reservoir. This paper presents a technique for capillary research data digital processing in order to obtain a function graph of reservoir pore channels by size distribution. In this case, a generalized mathematical model of capillary pressure curves is used. The generalized model makes it possible to increase the accuracy of capillary curves approximation in the medium and small pore channels area. In this regard, the proposed digital processing technique makes it possible to increase the accuracy and efficiency of constructing the pore channel size distribution function. Keywords: pore channels; distribution density; permeability; oil saturation; digital processing technique.

Modern industrial reservoir flow simulators are integrated software products consisting of several packages. Modeling of gas injection with various compositions, or hydrocarbon recovery from gas-condensate and oil-gas-condensate reservoirs, or thermal recovery methods requires a detailed account for composition of the fluid system. In these cases, compositional (multi-component) flow simulation is used to calculate component distribution between the coexisting phases, the number and the fractions of the phases, together with the flow equations for fluid components.. For this purpose, the flow simulator solves the thermodynamic subproblem using basic methods and algorithms analogous to the fluid modeling (PVT modeling) packages. The paper describes the main principles and specific features of implementation of the compositional modeling algorithms in several modern reservoir flow simulators. Keywords: compositional modeling; multicomponent flow model; reservoir flow simulator; isothermal and non-isothermal compositional modeling.

Liquid-phase aerobic oxidation of petroleum hydrocarbons catalyzed by carbon nanoparticles is focused on the real practical implementation over the rational processing of multicomponent petroleum feedstock. The use of metal-containing carbon nanostructures as catalysts allows known oxidation processes to be considered in the most modern strapping and simultaneously raises related questions about kinetics and mechanism of the process. This paper describes the formal kinetic regularities of the liquid-phase aerobic oxidation of the diesel fuel paraffin-naphthenic fraction in the presence of iron-containing multiwalled carbon nanotubes Fe@MWCNT. The purpose of the work is to determine the activity of the catalyst and the mechanism of its action. The reaction was carried out at 80°C, at which thermal decomposition of hydroperoxides is known to be almost non-existent and the reaction does not initiate. The induction period, the profile of the kinetic curves, and the oxygen uptake rate were taken as criteria for catalyst activity. As a result, it was shown that Fe@MWCNT additives have a significant ability to increase the rate of aerobic oxidation of diesel fractions. A general scheme of catalytic oxidation of hydrocarbons of the petroleum fraction in which the catalyst on a nanocarbon carrier reduces the dissociation energy of the C-H bond and activates the decomposition of hydroperoxides into active reactive particles has been proposed. Keywords: metal-containing carbon nanotubes; petroleum hydrocarbons; diesel fuel; paraffin-naphthenic fraction; oxidation induction period; catalytic hydroperoxide decomposition; oxygen uptake rate.

Excessive water production in oil and gas wells poses a significant challenge for reservoir management, necessitating effective water shut-off solutions. This study focuses on the development and evaluation of a colloidal silica-based fluid system tailored for high temperature water shut-off applications in challenging reservoir conditions. The system comprises colloidal silica and an activating salt, characterized by its low viscosity, enabling deep penetration and effective treatment. The evaluation methodology employed in this study encompasses visual assessment of gelation time and precise viscosity measurements. Key findings include the influence of temperature, salt concentration, silica content, and activating salt concentration on gelation kinetics. Higher temperatures, increased salt concentration, and elevated silica content were found to significantly expedite gelation, impacting the system’s efficiency. Moreover, different activator ions exhibited varying effects on gelation, primarily attributed to their charge density and size, adding nuance to the gelation dynamics. The study also revealed the system’s sensitivity to even minor variations in salt concentration, particularly when exposed to elevated temperatures. Based on these findings, a practical application strategy is proposed. When deploying silica gels in formations characterized by high salinity formation water and elevated temperatures, the introduction of a low-salinity water preflush is advised. This strategic approach mitigates premature gelation, ensuring the effectiveness of water shut-off operations. Keywords: water shut-off; silica gel; gelation time; sandpack; high temperature.

In this paper presents the development of a fuzzy controller for adaptive control of the parameters of the activated carbon adsorption process. The main objective of the developed control system is to increase the efficiency of the control of the technological process of adsorption by using intelligent technologies. It should be noted that the methodological basis for the design of fuzzy controllers is the concept of fuzzy logic. Also, for the development of fuzzy controllers for an adaptive control system, a model of the absorption process in the adsorber is constructed, taking into account multiple relationships between the parameters of the technological process. The conceptual model of the control object was developed taking into account the inherent internal relationships between the parameters of the technological regime and external disturbing factors. That is, fuzzy adaptive control allows you to adapt to changes in the technological parameters of the adsorption process by changing the control algorithm of the technological process. The expediency of using for adaptive control of technological parameters of the adsorption process by using fuzzy controllers is substantiated. The development of an adaptive control system based on fuzzy controllers was carried out using MatLab software, where a control model of the adsorption technological process was built, and the results were obtained and analyzed. Thus, fuzzy controllers evaluate critical situations and also regulate the parameters of the adsorption process based on logical rules. Keywords: adsorption; activated carbon; ethanol; fuzzy controller; system control; process parameters; adaptive control; fuzzy logic.

The task of studying the filtration processes of gas-liquid mixtures has been solved using mathematical modeling. A hydrodynamic model of the process of oil displacement by carbon dioxide is proposed, from which, under certain assumptions, equations describing various mechanisms of displacement can be obtained. In addition, methods for calculating the process of flooding of reservoirs with the use of carbon dioxide are considered. Using the example of a landfill site of one of the Ural-Volga deposits, the forecast technological efficiency of using carbon dioxide to increase oil recovery is calculated.

For the first time in the practice of horizontal well flooding the study investigates the influence of horizontal well length, number of stages, and proppant loading on productivity during hydraulic development of low-permeability reservoirs using horizontal wells. To increase the sweep efficiency in systems with horizontal wells, a new development systems configuration is proposed, relying on longitudinal horizontal production wells and transverse horizontal injection wells with respect to the regional stress direction. The use of this configuration will not only increase the efficiency of reservoir pressure maintenance systems, but also reduce capital costs for well construction by reducing the injection wells to production wells ratio per development unit while maintaining system stiffness.

Published: January 2024

This study examines the relationships between traffic safety innovations, innovation culture, and safety culture in four Norwegian county authorities three years after a comprehensive structural reform. Following the reform, the county authorities had to establish new organisations, routines, and systems. The study is based on qualitative interviews (N = 42) and a quantitative survey (n = 392) among people who work with traffic safety and/or mobility in the county authorities. The qualitative results show in particular that the respondents have gained new perspectives on traffic safety as a result of being co-organised with new professional groups. Additionally, we see examples of new methods and new forms of collaboration in traffic safety being implemented. The survey results show statistically significant differences between the county authorities' scores on an index for traffic safety innovations. County authorities' scores on this index is predicted by the county authorities' innovation culture, which in turn is predicted by safety culture. This indicates that innovation culture should be understood as an aspect of a learning safety culture. We find statistically significant differences between county authorities with respect to how demanding the organizational changes related to the regional reform have been for the county authorities studied. The results from this study can also be useful for change processes in other organisations.

Does Budget Deficit Crowd Out Private Investment? Cote d’Ivoire As A Focus
Authors: Keho Yaya
Published: January 2024

This study examines the impact of budget deficit on private investment in Cote d’Ivoire. It uses data from 1975 to 2022. Using the autoregressive distributed lag approach, the results disclose a negative relationship between deficit and private investment, providing support to the crowding out hypothesis. This suggests that high deficits driven by government expenditure slow down private investment. Estimating a threshold model, the results confirm the significance of a nonlinear relationship between deficit and private investment. The results indicate that budget deficit lower than 2.3% of GDP is positively associated with private investment. However, once the budget deficit exceeds this threshold, it turns to be neutral to private investment. Since 2020, the budget deficit is higher than the threshold of 2.3%. Therefore, policy-makers are advised to take measures reducing deficit at a level conducive to investment and economic growth. Government should improve tax revenue and restrain the growth of public expenditure while enhancing its efficiency.

Soil erosion on agricultural land in the north of Ireland: past, present and future potential
Authors: Mullan Donal
Published: January 2024

Soil erosion in Ireland is a considerable environmental problem with respect to the ‘off-site’ transport of sediment and pollutants out of fields and into nearby water courses and the neighbouring environment. This paper examines this important issue by presenting evidence for past and present-day soil erosion in Ireland through the use of secondary documentary and primary observational evidence. An original modelling-based study is also conducted at six locations across the north of Ireland in order to project future soil erosion rates for Ireland under a changing environment. Results reveal that numerous incidences of soil erosion occur across Ireland in the present day, and that past erosion was more widespread due to increased cultivation to support a growing pre-famine population. Projected rates of soil erosion under the impacts of future climate change reveal the potential for increased erosion and indicate that off-site impacts associated with declining water quality and ‘muddy flooding’ of infrastructure and property may become more widespread in the future. This illuminates the need to begin monitoring the problem in the present day in order to better manage a problem projected to escalate in the coming decades.
Hágár országában : A Magyar Királyság zsidó közösségei az Árpád-korban
Authors: Végh András
Published: January 2024

A tanulmány a Magyar Királyságban élő zsidó közösségek helyzetének és anyagi kultúrájának áttekintésére vállalkozik, időrendben visszafelé haladva, az Árpád-kor végétől annak elejéig. Az Árpád-kor végén a zsidók a kialakulóban lévő városokban laktak, és bár ott a király által az adott városnak adományozott ugyanazon jogokat, élvezték, mint a város keresztény polgárai, jogi helyzetükben ugyanakkor negatív irányú változást is észlelhetünk. Például, bár még a 13. században is tudunk zsidó származású kamaraispánokról, az 1279-ben tartott budai zsinat újra tiltotta a zsidóknak bármilyen közhivatal viselését, és körülbelül ekkortájt vált végérvényesen lehetetlenné zsidó számára lehetetlenné bármiféle hivatal betöltése a magyar királyi udvarban. A zsidók közösségekről a 11–12. századok során is a királyi hatalmi központokban, központi településeken rendelkezünk szórványos adatokkal. A zsidók számára addigi életmódjuk fokozatos nehezedését a keresztény Magyar Királyság lassú kiépülése jelentette, melyek I. (Szent) László és I. Kálmán királyok törvényeiben is megjelentek. Fontos megemlíteni ugyanakkor, hogy a Magyar Királyság az Árpád-korban biztos lakóhelyet jelentett a zsidóknak, a Nyugat-Európában tapasztalható atrocitások (vagyonfosztó sarcolások, pogromok stb.) nem értek el idáig.

В работе дается обобщение характеристик карымских погребений из могильников (Ревда-5, Козлов-Мыс-2, Красноярский-IV, Алексеевка-50, Алексеевка-51, Усть-Тара-7) южнотаежного Тоболо-Иртышья IV–VI вв. н.э. К специфическим чертам карымской группы погребений отнесены такие признаки, как совершение грунтовых или подкурганных захоронений в узких овальных или подпрямоугольных ямах, северная ориентировка погребенных, наличие кремаций и трупосожжений. При сравнении параметров южнотаежных погребений карымского типа с практиками родственного ему населения Нижнего Приобья обнаружены существенные отличия последних в отсутствии следов прижизненной деформации черепов, бедности погребального инвентаря, положении покойных, что указывает на быструю метисацию культуры при воздействии на нее лесостепных традиций бакальского (IV–IX вв. н.э.) и предшествовавшего ему саргатского (IV/III в. до н.э.–III вв. н.э.) населения Тоболо-Иртышья.

Todavia, o genoma pode apresentar variações na sequência de genes específicos que modulam os fenótipos de performance física, o chamado polimorfismo genético. Este prediz pequenas variações na sequência de DNA capazes de alterar o desempenho físico. Entretanto, fatores individuais, nutricionais, ambientais e comportamentais devem ser considerados na avaliação de um atleta.

Quando se refere à enfermagem, o primeiro pensamento que perdura no imaginário da comunidade é o cuidar, de fato, a profissão enfermagem tem como base assistir o paciente de maneira holística, ou seja, em sua totalidade, de forma que abranja os aspectos físicos, mentais e emocionais, porém, tal profissão não se resume somente aos cuidados prestados. A enfermagem detém suas particularidades e consequentemente, diversas formas de atuação que ainda não são difundidas de maneira explícita pela sociedade e por isso, o senso comum sobre essa temática torna-se dominante. Esse é alterado, somente, quando acadêmicos e profissionais passam a ter mais contato com a área e a realidade passa a ser propagada por eles. Relatar a mudança gradual de acadêmicos de enfermagem e enfermeiros atuantes na profissão acerca da visão sobre a profissão enfermagem. Estudo qualitativo, descritivo, comparativo realizado com sessenta alunos de em um centro acadêmico e doze enfermeiros de diferentes áreas de atuação em Teresina-PI. A coleta de dados foi realizada entre os meses maio e junho de 2023 por meio de questionários contendo questões estruturadas com perguntas objetivas e subjetivas. Os resultados obtidos constataram certas semelhanças nas respostas dos enfermeiros e constatou-se a existência de mudanças em tal ótica sobre a enfermagem.

Analisar o entendimento de adolescentes quilombolas sobre gravidez na adolescência. Trata-se de uma pesquisa exploratória, descritiva de caráter qualitativo, do tipo pesquisa-ação que proporciona uma estratégia voltada para a junção da investigação mais ação (ação-reflexão-ação). O percurso metodológico adotado fundamentou-se na estratégia do método da Roda proposto por Campos (2007). Sujeitos: adolescentes, na faixa etária de 12 a 17 anos, matriculados em uma instituição de ensino público. O local do estudo foi uma escola de ensino fundamental, localizada no quilombo do Curiaú, há oito quilômetros da cidade de Macapá/AP. A coleta de dados: foi realizada por meio de entrevista semiestruturada, ancorada no desenvolvimento de uma oficina, com carga horária de duas horas, com apresentação de uma obra cinematográfica com temática ética, no sentido de impulsionar e qualificar a reflexão sobre gravidez na adolescência, sendo que após o evento foi aplicado o instrumento de coleta de dados. A análise de dados: Se deu por meio de análise de conteúdo proposto por Bardin com auxílio do software atlas.ti. 9.0. Resultados e Discussão: a análise dos dados proporcionando a identificação de duas categorias: “a obra filmística como estratégia para reflexão sobre gravidez precoce” e “o cenário de diálogo sobre gestação na adolescência”. Considerações finais: O estudo revelou que as narrativas dos adolescentes quilombolas traz implicações bioéticas, pois revelou a gravidez precoce como um problema vivenciado por aqueles jovens, afastando principalmente as jovens do ambiente escolar e o abandono da família/companheiro. Assim, sugere-se que os profissionais de saúde desenvolvam estratégias para envolver alunos e professores tanto no ambiente escolar quanto nos serviços de saúde.
