Authors: Kurniawan Deni , Nur Suhascaryo KRT , Swadesi Boni
Published: May 2022

The AB-30 well is an oil producing well located in the AB Field. Production performance data shows that AB-30 shows excessive water production behavior or is a high water cut production well. In addition, the interpretation of CBL data shows an amplitude value of <10 mV in the productive interval. This condition is an indicator that the primary cementing activity in this well is not good. Therefore, a comprehensive and integrated analytical method is needed to identify the problem of excess water production and to design and plan water shut-off activities through squeeze cementing as an effort to mitigate the problem of high water cut to economic analysis.The research begins by identifying the problem of excess water production, whether caused by water channeling, water coning, changes in water oil contact, or by the physical properties of the reservoir rock. Identification is done through production analysis and water diagnostic plots. The next stage is to evaluate the interpretation of CBL Logging results to strengthen the results of production data analysis. After confirming that the problem of excess water production is caused by poor cement bonding cement, the next step is to calculate the cement work program in order to repair the bad cement bonding. Subsequently, the productive zone interval re-perforation was carried out according to the results of the OH Loh Co Log evaluation. No less important is to conduct an economic analysis as a basis for whether or not this work is feasible.The result of this research is that the water shut-off activity went well and was able to reduce the level of excess water production in the AB-30 well and optimize oil production so as to provide a good economic indicator of oil recovery. Remedial cementing work for bonding repair was carried out at well AB-30. The first work is to close the existing layer, followed by Logging evaluation (CBL-USIT). The evaluation results showed that the cement bonding was good with the CBL amplitude parameter < 10 mV. After that, the productive zone reperforation was carried out. The economy by considering the values of economic indicators such as Pay Out Time and Rate Of Investment showed positive results so that the priority and strategy of well intervention could be continued. The results obtained before the well intervention were 148 BOPD oil production, 97% water cut after well intervention was 880 BOPD average oil production, 0% water cut for 1.5 months
Multi Regression Analysis to Suggest Optimum Drilling Weight On Bit and Penetration Rate for Optimum Rate of Penetration Propose Well
Authors: Lukmana Allen Haryanto
Published: May 2022

R is a system for analyzing statistical data included in open source software group or also called freeware. R software less popular when compared with other paid statistical software such as SPSS, MINITAB, SAS or Eviews. Limited references and support especially in Indonesian, is one of the reasons statistical users prefer commercial statistical packages over free R software and provide results that are no less powerful and interesting graphics systems. Among many statistical techniques that R software can accomplish, one of the most popular is multiple regression analysis. In this article, we will discuss about multiple regression analysis modeling using R software as an alternative software for determining Weight on Bits (WOB) and optimal Rate of Penetration (RPM) in oil and gas drilling. Multi-regression analysis aims to get maximum drilling rate at drilling process, which is reduce drilling time and drilling cost. Bourgoyne and Young ROP models have been chosen to observe effects of several parameters during drilling operations such as drilling depth, pore pressure, equivalent circulation density, bit weight, rotating speed, bit tooth wear and jet collision force were extracted from the final drilling report. Results of the analysis are used to determine the optimum value of the weight of the bit which provides optimal drilling operations and optimized WOB has been calculated for several data points. the results show that R software can be used for multi regression analysis, and and produce a multi-regression equation that can be used to predict the optimum WOB and RPM for further drilling in equivalent rock formations.

Authors: Kowsana B. , Muraleethran P.
Published: May 2022

Sustainability Reporting is an emerging concept followed by the organizations all over the world. The overall objective of the organizations is to grow consistently and sustain for a long period of time. Sustainability Reporting indicates the act of quantifying, evolving and being responsible to all stakeholders for the performance of the organizations towards their goal of achieving sustainability. In today’s changing and complicated business world, Sustainability practices are likely to have an impact on corporate profitability and financial performance of the organizations. Therefore, this study intends to examine the impact of Sustainability Reporting on Financial Performance of Listed Companies in Sri Lanka. Return on Assets is used as dependent variable to measure the Financial Performance whilst Economic Performance Disclosure Index, Environmental Performance Disclosure Index and Social Performance Disclosure Index are used as independent variables to measure the level of Global Reporting Initiative (GRI) based Sustainability Reporting. This study considers 39 companies listed on Colombo Stock Exchange for the period from 2016 to 2019. This study uses secondary data gathered from the annual reports of these companies. The data is analysed by means of descriptive statistics, correlation analysis and regression analysis using the software E views 8. The results of the regression analysis show that Environmental Performance Disclosure and Social Performance Disclosure significantly impact on the Return on Assets of the company whereas Economic Performance Disclosure shows an insignificant impact on Return on Assets. Correlation analysis indicates that there is an insignificant relationship between Sustainability Reporting as a whole and Return on Assets at 5% significant level. However, while considering each of the independent variables, Social Performance Disclosure has a significant negative relationship with Return on Assets. Further, Economic and Environmental Performance Disclosures have insignificant relationship with Return on Assets. The findings of the study have an important implication for the management of the companies and other interested parties. Further researches can be extended by choosing more time periods of data and choosing other indicators of financial performance.

Published: May 2022

An attempt is made to explore the specifics of psychological readiness for professional activity, in particular as a basis for future pedagogical activities of fitness and recreation professionals in the context of psychological and pedagogical problems. Theoretical analysis of the study of the concept of "psychological readiness" in modern science and summarizes the characteristics, states and mental processes of the individual that lead to professional activity in the field of knowledge 01 Education / Pedagogy.

Despite the different approaches in research, most authors consider psychological readiness as a specific phenomenon - an integrative formation that has a complex, dynamic, multicomponent structure. Summarizing research data on the problem of psychological readiness for teaching, we state the fact that they are not mutually exclusive, but expand, deepen and complement the idea of the complexity and diversity of the concept of psychological readiness for teaching. It was found that in the structure of professional activity of educators most researchers highlight the presence of: adequate motivation; general and special knowledge; professional skills and abilities; professionally important personality traits. Motivation is conditioned by a positive attitude to professional activity, in obtaining the necessary amount of special and psychological knowledge, professional skills and abilities, focus on high results of pedagogical activity, the desire for professionalism.

It is investigated that the structure of psychological readiness for pedagogical activity consists of such general components as: orientation, psychological and pedagogical knowledge and professional skills (more often they are considered as the main characteristics of teacher competence), ability. Most of the authors single out these components as the main integral characteristics. The study identified three main levels of psychological readiness in psychology, such as: the level of non- professional training, pre-vocational training, vocational training. Identifying the level of psychological readiness is very important for the quality functioning of the educational and training process, so various psychological techniques are used, working at the level of basic personality traits and states in general, and at the level of professional competence and cognitive abilities of future fitness and recreation specialists in particular.

Published: May 2022

The authors of this article collected and analyzed research materials that reveal the essence of the concept of psycho-emotional state and its impact on the quality of educational activities of students in the new paradigm of higher education. The standards are based on a competency-based approach and share the philosophy (principles and values) of the European Higher Education Area as defined in the Bologna Communiqué and the European Commission's International Project on Harmonization of Educational Structures in Europeю.

The competency approach is such that it is focused on the degree of formation of professional, general cultural competencies and not on the assessment of acquired knowledge and skills. This means that the field of education for the formation and improvement of a particular person is changing the ways of organizing educational systems. In the competency approach, systematic knowledge of the world around the graduate is replaced by a set of narrow-profile knowledge for orientation in the space of the profession, while they do not provide opportunities for young professionals to change that space. Given the fact that one of the main tasks of higher education in Ukraine is the creation of competitive human capital, the requirements for a person, his physical and mental qualities are changing. At present, it is important for an individual to learn to live fully in the new energy of social and moral tension, to be ready to learn throughout life, to work effectively in the context of globalization and multiculturalism.

In accordance with the current curriculum reform, in addition to the theoretical and pedagogical problems of the curricula, the study of psychological problems is necessary in terms of identifying learning difficulties of young students. Psychologicalization of the concept of the education system is the main demand of the day. For this purpose, from the development of curricula and textbooks to the pedagogical process we face in this process, learning and mastering, pedagogical attitudes, joint activities, learning difficulties, etc. problems must be solved. “Currently, school psychologists are unaware of the content of subject curricula and find it difficult to provide necessary assistance to teachers in this area. Teachers, on the other hand, approach the problem from a purely pedagogical point of view and do not strictly follow the principle of individualization and differentiation of the learning process when assessing students' abilities. As a result, the development of skills necessary for the future life of the student is not provided enough.

Pre-service teachers’ approaches to designing technology-based activities in anchored instruction framework
Authors: GÜNBAŞ Nilgün
Published: May 2022

Teachers’ beliefs and skills in, and attitudes towards technology are the factors shaping their technology use in education. However, teacher preparation programs don’t sufficiently support pre-service teachers in this regard. One way to improve their technology beliefs and skills in, and attitudes towards technology is to have them design theory-based technology learning environments. In this study, pre-service mathematics teachers designed anchored instruction-based mathematics learning environments and their approaches for the process were revealed. 52 pre-service teachers went through a 14-week learning period and then asked to build technology-based mathematics learning materials. Their materials were designed based on three design principles of anchored instruction. Upon the completion, projects applying all the necessary requirements in good, average, or poor level were selected with a purposive sampling method. The requirements were specified as workability, interactivity, narration, completeness and representing anchored instruction’s three design principles. The designers of these selected projects were interviewed with semi-structured interview questions. Results indicated that their design approaches are in line with anchored instruction theory’s suggested benefits. Their technology beliefs are positively affected and their judgments about technology-based instructional material design are supported by related literature in favor of students’ learning. Implications for teacher education programs are discussed.

Tóm tắt:

Hố đào sâu được sử dụng thường xuyên khi thi công các công trình dân dụng. Vấn đề chuyển vị và biến dạng nền xung quanh hố đào là một vấn đề lớn cần phải giải quyết, đặc biệt là khi thi công hố đào trong đô thị. Vấn đề này thường được giải quyết bằng việc sử dụng hố đào dạng trụ tròn. Do dạng kết cấu hình tròn, sẽ tạo ra hiệu ứng vòm dẫn đến áp lực đất tác dụng lên tường vây nhỏ hơn thông thường, đồng thời toàn bộ áp lực hướng tâm sẽ chuyển thành lực vòng theo phương chu vi tường. Biến dạng hố đào và nền xung quanh do đó cũng nhỏ. Tuy nhiên việc tính toán phân tích hố đào trụ tròn thường phức tạp, đòi hỏi phải sử dụng công cụ mô hình 3D. Trong bài báo này trình bày cách xác định áp lực đất tác dụng lên tường vây của hố đào hình trụ xuất phát từ các công thức giải tích. Kết quả tính toán được so sánh với kết quả quan trắc của công trình thực tế. Trên cơ sở đó một trình tự thiết kế tường vây của hố đào trụ tròn cũng được đề xuất. Trình tự thiết kế này có thể được sử dụng trong giai đoạn thiết kế sơ bộ của hố đào dạng trụ tròn.
