Injection Temperature Impacts on Reservoir Response during CO2 Storage
Authors: Samaroo Mahendra , McClure Mark , Fowler Garrett , Chalaturnyk Rick , Dusseault Maurice B. , Hawkes Christopher 
Published: February 2024

SummarySustained injection of industrial-scale volumes of cold CO2 into warmer subsurface rock will result in extensive cooling which can alter rock mass mechanical behavior and fluid migration characteristics. Advanced simulation tools are available to assess and characterize such phenomena; however, the effective use of these tools requires appropriate injection temperatures and rock thermophysical parameters (in addition to geomechanical and hydraulic properties). The primary objective of this study was to demonstrate the sensitivity of injection-induced tensile fracturing and fault reactivation to injection temperature and reservoir thermophysical properties during CO2 injection operations. This was achieved by (1) compiling and reviewing thermophysical parameter data available for formations in the province of Alberta, Canada, and CO2 injection temperature records for CO2 injection projects in western Canada and (2) using a 3D, physics-based, fully integrated hydraulic fracturing and reservoir simulation numerical model to examine the geomechanical response of several potential CO2 reservoirs in the Alberta Basin as a function of injection temperature, thermal conductivity (TC), and coefficient of linear thermal expansion (CLTE) values. The simulation results indicate that reducing the fluid injection temperature from 15°C (assumed in previous work) to 2°C (conservative value selected based on temperature data reviewed in this work) could trigger extensive vertical (20–130 m high, 100–600 m long) tensile fractures with rapid fracture initiation and full vertical growth within short periods (weeks to months) and continued horizontal length increase. When low values for thermophysical properties are used, the results show that thermally-induced tensile fracturing is unlikely, whereas the use of high values results in extensive tensile fracturing in all simulations. A similar conclusion was reached for the thermally-induced reactivation (unclamping) of proximal, critically-stressed faults. Notably, slip is predicted for all simulations where high thermophysical property values are used. This confirms that accurate determination of minimum fluid injection temperature and thermophysical parameters is important for containment risk assessment for commercial-scale CO2 storage projects. Another significant outcome of this work is the observation that most thermophysical parameters in the available data were measured using experimental conditions and/or temperature paths that are not representative of CO2 injection projects. As such, the development and validation of best practice approaches for accurate assessment of these parameters seem necessary.
Measurement of Casing Buckling in Producing Intervals

Published: February 2024

Abstract
Extensive casing damage has been encountered within many of the production intervals of wells in the South Pass Blocks 24 and 27 fields located in the delta of the Mississippi River. As part of a program to ascertain damage configuration, a gyroscopic tool was designed to obtain accurate measurements of lateral casing deflection over relatively short intervals. Use of this tool, referred to as a Kinkmeter, has revealed that the principal mode of damage previously thought to have been collapse or shear, has been buckling in the producing interval. Since similar environments exist elsewhere, particularly in the Gulf Coast region, casing buckling in production intervals is probably widespread. In addition, offsets have been measured with the Kinkmeter adjacent to faults.
This report presents information on the design and field use of the Kinkmeter as well as the results of Kinkmeter surveys in a test well containing pipe bent to predetermined deflections. A program for computing the severity of bending and the magnitude of lateral deflection is presented. Photographs of scale models prepared from measurements of casing deflection obtained with the Kinkmeter are included.
“Old” and “new”, “first” and “last” in the works of N. Abgaryan: on the linguistic representation of time modes
Authors: Чжао С. 
Published: February 2024

Исследование посвящено выявлению способов репрезентации модусов времени в художественном тексте на материале произведений Н. Абгарян. Высказывается гипотеза о возможности соотнесения модусов времени с особым макроконцептом «Время», значимое место в структуре которого занимают понятия «старый» и «новый», «первый» и «последний». Делается вывод о том, что ключевую роль для авторской картины мира играет модус прошлого; при этом мотивы смерти, тяжелых испытаний в прошлом тесно переплетаются с идеей победы жизни над смертью, надежды на лучшее настоящее.
The research focuses on identifying the ways of the time mode representation in the literary text on the material of Narine Abgaryan's works. It is hypothesized that the time modes can be correlated with a special macro-concept “Time”, a significant place in the structure of which is occupied by the concepts of “old” and “new”, “first” and “last”. It is concluded that the key role for the author's picture of the world is played by the past mode; in this case, the death motifs, severe trials in the past are closely intertwined with the victory of life over death, hope for a better present.

Published: February 2024

Актуальность исследования заключается в непрерывном расширении корпуса англоязычной неологической лексики, перманентным интересом лингвистов к данной, наиболее востребованной части неологического англоязычного дискурса, необходимостью научной интерпретации отображения коллективного опыта в анализируемом пласте лексики. Цель статьи – анализ когнитивных и прагматических особенностей транспортных неологизмов англоязычного дискурса для выявления в их дефинициях особенностей менталитета создателей данных неологизмов. Методологической базой исследования послужили работы ученых, анализировавших семантический и когнитивно-прагматический потенциал новой лексики. Практическим материалом послужили неологизмы англоязычного дискурса, отобранные при помощи метода сплошной выборки из электронных неографических источников (Cambridge Dictionaries Online и Urban Dictionary). Анализ транспортных неологических единиц в английском языке с точки зрения когнитивного и прагматического аспектов позволил выделить новые виды номинирования транспортных средств, людей, их увлечений и хобби, видов спорта, а также их связь с концепцией «умного города» как части урбанистического дискурса.
The relevance of the study is ensured by the continuous expansion of the corpus of English neological vocabulary, the permanent interest of linguists in the most demanded part of the neological English discourse, the need for scientific interpretation of the collective experience in the analyzed layer of vocabulary. The aim of the article is to analyze cognitive and pragmatic features of transport neologisms in English discourse to identify in their definitions the mentality features of the creators of these neologisms. The works of Russian and foreign scholars who analyzed the semantic and cognitive-pragmatic potential of the new vocabulary constitute the methodological basis of the study. The practical material was taken from electronic neographic sources using the continuous sampling method (Cambridge Dictionaries Online and Urban Dictionary). The analysis of transport neological units in the English language from the point of view of cognitive and pragmatic aspects allowed us to identify new types of nomination for vehicles, people, their hobbies, sports, as well as their connection with the concept of a “smart city” as a part of urban discourse.

The development of industrial technology requires companies to be able to use existing resources. The most important thing in the production process is the machine. PTPN XII Ngrangkah Pawon is a limited liability company owned by the Republic of Indonesia and PT Perkebunan Nusantara III (Persero). The use of machines is also used in the PTPN production process. The purpose of this research is to find out whether it is possible to minimize the cost of maintaining the vis pulper machine through preventive maintenance and repair maintenance methods. This type of research is carried out quantitatively by observing and studying the material obtained during the production process for three years (2020-2022). This research was conducted offline for 1 month starting from early July to August. Data analysis was carried out using two methods, namely repair policies and preventive policies. maintenance using repair maintenance with a period of 3 years, namely in the production process by repair calculation in May 2020 the results were Rp. 497,354/week while calculating maintenance cost preventive maintenance results obtained Rp. 708,817/week by scheduling every 4 weeks. For the results of treatment repair calculation maintenance in May 2021 the production process obtained a result of Rp. 6,797,131/week while on preventive maintenance get the calculation results of Rp. 8,508,950/week with scheduling once a week. Finally, in 2022, in May, the calculation results were obtained using repair maintenance Rp. 373,089/week while on preventive maintenance Rp. 524,366/week with a schedule of 4 weeks. Based on the results of the calculations it is explained that minimizing costs using the method of preventive maintenance can be applied, but to get a cheaper fee it is better to use a repair policy maintenance because the estimated results of spending calculations are cheaper compared to using maintenance expenses for preventive maintenance.

Published: February 2024

Purpose: The gender pay gap in South Africa has greatly reduced since the implementation of the Employment Equity Act in 1998. However, there is still a pay gap that cannot be sufficiently explained and addressed by government leaders and scholars. Scholars, policymakers, the radical left, and feminists have carefully highlighted and addressed what is considered to be the major causes, such as segregation of women, women's stereotypes, marginalization of women, wage penalties due to time away from work, child nurturing responsibilities given to women, and inequality in salaries and remunerations. However, the World Bank reported that from 2007 on, the gender pay gap in South Africa was no longer showing any sign of reduction. It was stagnant and thereafter oscillating. As such the purpose of this research is to investigate the causes of the stagnation and the oscillation, and to provide recommendations.

Theoretical Framework: This research used multivariate analysis theory to make further contributions on the causes of gender pay inequality in South Africa in order to address the stagnation and oscillation of the existing pay gap.

Design/Methodology/Approach: The research method used is qualitative approach. The research design comprises men and women who are already in the work industry in both private and public sector.

Findings: This research found that gender pay gap in South Africa is caused by women’s family-career crisis as a main contributor, followed by interests and personality traits, equality of opportunity and career selection.

Research Implications: This research paper gives light to further research in Women’s family-career crisis as it seems to be the major contributor to gender pay gap in South Africa. The assessment of how impactful family-career crisis is on gender pay gap is also essential in order to understand the magnitude of it on gender pay gap in South Africa.

Originality/Value: This research paper found significant causes of gender pay gap such as ‘family career-crisis’ that shows to heavily contribute to the gender pay in South Africa. This might further give clarity to the governments on the existence of gender pay gap. Moreover this research may help in redefining the government policies on the approach of gender pay gap.
