Effective EOR methods in high-viscosity oil fields: cyclical GEL-polymer flooding and ASP flooding

The presented work discusses increasing oil recovery factor using physicochemical EOR methods. This article presents the field pilot tests results related to cyclical gel polymer flooding technology as applied under the conditions productive reservoirs rich in high-viscosity oils (viscosity in reservoir conditions above 300 mPa s) of the Buzachi North oil field, extending the boundaries of application of these methods. The work used the methods of hydrodynamic modeling, mathematical analysis; the necessary parameters of fractures and super reservoirs for calculating the working volumes of the injected compositions were estimated using tracer studies.

Evaluation of Residual Oil Saturation With Use of Single Well Chemical Tracer Test Swctt For Estimation of Eor Efficiency. From Theory to Experiment

This article provides a brief overview of the theory of tracer studies, describes approaches to the interpretation of tracer studies using both analytical methods and hydrodynamic modeling, compares the results of analytical and numerical interpretation. The article also describes the problems that arise during the interpretation of real case study.

Selection and Justification of Technologies for Enhanced Oil Recovery Methods Using Inter-Well Tracer Survey

Justified application of enhanced oil recovery (EOR) methods is one of the key tasks of oil operating companies for the effective development of not only brown oil fields at a mature stage of production, but also for green fields. The selection and justification of one or another method of enhanced oil recovery for certain geological conditions often requires not only looking for worldwide experience, conducting laboratory tests on a core, but also performing pilot tests at a polygon area. The subsequent full-field implementation of EOR method requires confirmation of its effectiveness based on the increase in oil recovery factor. This article describes both the experience of using interwell tracer studies to substantiate the effectiveness of EOR technologies in pilot areas, and the experience of evaluating the effectiveness of EOR technologies with full-field implementation in various fields. The work carried out on the integrated use of tracer studies makes it possible to apply a scientific and engineering approach to the selection of an enhanced oil recovery method by assessing the sweep efficiency before and after the application of the EOR technology. Examples of the use of this integrated approach for different oil fields are given. The presented technologies and experience of the work performed will significantly speed up the choice of the EOR technology for certain geological conditions and verify the effectiveness of the selected EOR method.

Design and Development of Alumni Career Information System using PHP MySQL

Alumni data collection at the Electrical Engineering Vocational Education Universitas Sultan Ageng Tirtayasa was still performed manually and there were no career information media about soft skills training and development, tracer studies, and job vacancies information. Therefore, media is needed to accommodate career information and alumni data collection quickly and effectively. The web-based information system using PHP MySQL was developed and tested for feasibility as an information medium for soft skills training and development, tracer studies, job vacancies information, as well as career counseling and consulting. This study used a Modify R&D as a development method and the waterfall method as a development model consisted of analysis, design, coding (implementation), and testing. The testing was carried out by 37 people consisted of software experts, admins, alumni, and students of Electrical Engineering Vocational Education. The test was based on the ISO9126 standard with functionality, usability, reliability, and efficiency aspects. Based on the results, the functionality aspect had a score of 77 (very feasible), the usability aspect had a score of 87.8 (very feasible), the reliability aspect had a score of 100% (very feasible) and the average page load time was 3.48 seconds (feasible).

Improving Graduate Profiles Through Tracer Studies at University

Universities are encouraging efforts to improve their overall quality, including their graduates’ profiles. The absorptivity of graduates in industries or users has become one of the indicators of graduates’ profile quality. This tracer study aimed to get data from graduates dealing with compatibility of knowledge and skills acquired with their job. This program was carried out with the awareness of the university for the graduates’ empowerment. Some of the common problems found in conducting this program were collecting data from graduation books (making the data is less accurate), many telephone numbers could not be contacted or were not active, the time required by respondents while answering questionnaires over calls, and the total number of respondents being less than the expected target. This is because the processes used in the tracer study can be tedious for the respondents (alumni), and they lose interest. The method used in tracer study consists of four stages: (1) preparation, (2) implementation, (3) analysis, and (4) evaluation of results. The preparation stage covers updating graduate data, developing questionnaires, and arranging for and training invited surveyors. The implementation phase consists of deployment, monitoring, and the remaining processes, while the analysis stage is the process of analyzing and recapitulating the questionnaire. The final evaluation phase is the overall reporting and assessment stage of the program. All graduates are expected to be able to be tracked through this method.

Assessing the employability and employment destinations of professional psychology alumni

Professional training in psychology typically focuses on competencies and learning outcomes. However, this does not necessarily translate into long-term employability. Graduate tracer studies are recommended for exploring employment destinations and employability. Graduate tracer studies are noted to be of particular use for investigating health professionals’ career paths and examining field-specific issues. The reported study examined the employability and employment destinations of 29 alumni from two psychology Master’s programmes at a South African higher education institution, by incorporating best practices for tracer studies and survey research. Results indicated that 86.2% had secured employment in various fields and sectors, suggesting their skills and training were relevant and transferable. Differential patterns of registration with the Health Professions Council of South Africa were reported. Most respondents identified their studies as closely related to their work, and pragmatic reasons were provided by those pursuing work in unrelated fields. Entrepreneurial skills were identified as a gap in their training, that, if included, has the potential to boost employability. Graduate employability was identified to be a complex, non-linear issue. Professional competencies are, therefore, not sufficient for conceptualising employability within the South African context. A broader and more nuanced understanding of employability is needed. Practically, this means that educational processes need to prepare students for securing long-term employment. The tracer study methodology applied in this study may be utilised by other institutions and disciplines to explore key issues of employment and employability in the South African health professions and higher education context.
