General Analytical Model for Thermal-Solvent Assisted Gravity Drainage Recovery Processes
Authors: Motahhari Hamed Reza , Khaledi Rahman
Published: February 2018

Thermal-Solvent Assisted Gravity Drainage are recovery processes in which the stimulation mechanism for bitumen viscosity reduction is by heating and/or dilution. Different gravity drainage recovery processes can be included in this category depending on the range of the injection temperature and the solvent concentration in the injection stream. Examples are SAGD, SA-SAGD, VAPEX and heated VAPEX. The performance behavior of these processes is significantly driven by the complex thermodynamic interaction of steam and solvent, heat transfer, multiphase fluid equilibrium and flow in the porous medium.

In this study, we develop a general analytical model for gravity drainage processes by incorporating mass transfer mechanisms (including diffusion and dispersion) and heat transfer mechanism by conduction. In particular, we incorporate the dependency of diffusion and dispersion coefficients on concentration, temperature and drainage velocities, respectively. We utilize a novel approach to analytically solve the second order non-linear partial differential equation which governs mass transfer within the mass boundary layer. The resulted closed-form analytical model provides oil drainage rate due to gravity and heat and dilution effects as a function of reservoir and fluid properties. The developed model in this work provides a new perspective into the mass transfer mechanisms and their relative importance within the mass transfer boundary layer at different operating conditions.

The consistent application of the new model to the gravity drainage processes ranging from SAGD to VAPEX demonstrated using laboratory data from literature. It is shown that the predicted concentration distribution profile by the model with the concentration-dependent diffusion coefficient is profoundly different than the predicted profiles with a constant diffusion coefficient. The modeling results demonstrate that the dispersion can be several orders of magnitude greater than diffusion for solvent assisted gravity drainage process at the elevated temperatures. In addition, the contribution of the mass transfer boundary layer to oil production rate can be significantly greater than the heat transfer boundary layer despite being considerably narrower than the heat transfer boundary layer at the elevated temperatures. These findings confirms that the performance of solvent assisted gravity drainage process can be more favorable at the elevated temperatures.
3-D Physical Modeling of Hybrid Steam and Oxygen Injection for In-Situ Recovery of Oil Sands

Published: February 2018

Alberta (Canada) has the third largest proven reserves of oil in the world, mostly comprised of bitumen and heavy oil. To date, Steam Assisted Gravity Drainage (SAGD) has been the only commercially viablein-situ recovery technology for the Athabasca Oil Sands, but the current economic conditions have made the SAGD technology challenging, even for some high quality reservoirs. Moreover, from an environmental perspective, large water usage and high carbon emissions also make SAGD difficult to sustain. Due to the current low oil prices and rising penalties on carbon emissions, there is a need to develop improved recovery technologies that are more thermally efficient, with reduced environmental impact and at the same time economically feasible to develop.

One of the technologies that has the potential to overcome these economic and environmental shortcomings is a hybrid steam and in-situ combustion process (ISC) called SAGDOX, as this process offers advantages over pure steam injection such as greater energy efficiency, lower water usage and reduced carbon emissions. The SAGDOX (SAGD and Oxygen Injection) process, which is proprietary to Nexen (Kerr, 2015), combines the benefits of both SAGD and ISC processes. Steam is used to preheat and pre-condition the reservoir, also aiding in carrying heat from the combustion zone towards the rich oil saturation zone. One of the main advantages of SAGDOX is the elimination of most of the nitrogen that otherwise would be injected when using air and this reduces the amount of non-condensable gas (NCG) in the reservoir substantially. Heat delivery to the formation using a combination of steam and enriched air injection is more energy efficient than pure steam injection and reduces the steam-oil ratio compared to SAGD. This also lowers the volumes of steam condensate in the produced fluids and thus reduces the produced water handling and processing requirements.

The purpose of this study is to provide data to evaluate the feasibility of the SAGDOX process using a 3-D laboratory physical model. A description of the physical model is provided along with the method of operation. The results from two tests are presented and the findings from the experimental studies are also discussed.
Liner-Deployed Inflow Control Devices ICD Production Results in MacKay River SAGD Wells
Authors: Becerra O. , Kearl B. J. , Zaini F. , Melo M. , Woiceshyn G.
Published: February 2018

Ever since horizontal drilling became prominent decades ago, it has been the goal of oilfield operators to find an effective mechanism for controlling the toe-to-heel flux into the production liner to delay and/or reduce the inflow of unwanted fluids such as water, gas and steam, in order to maximize sweep efficiency and oil production/recovery.

Inflow Control Devices (ICDs) are basically flow restrictors installed along the completion string to alter the pressure drawdown on the reservoir by choking back the high permeability/high mobility zones while allowing more influx from the lower permeability/lower mobility zones. In steam assisted gravity drainage (SAGD) production wells the primary goal is to operate at lower subcool while minimizing live steam production. The pace of ICD technology adoption has accelerated amongst the operators since its benefit was made prominent in the Surmont field (Stalder 2012).

PetroChinaCanada (formerly known as Brion Energy) recognized the technical opportunity and commenced implementation of an ICD technology trial at its MacKay River asset. The technology selection, ICDs sizing and performace prediction was conducted in 2013 (Becerra et al). In 2014 two SAGD production wells, each located on different pads, were selected to evaluate if ICDs could have a beneficial impact on performance.

The purpose of this paper is to present preliminary results of the two ICD producer wells which, as of November 2017, have shown superior performance to their non-ICD neighboring wells after about 6 months of production.

Authors: Coburn Carl W. , Adjesiwor Albert T. , Kniss Andrew R.
Published: February 2018

Creeping bellflower (Campanula rapunculoides) is a difficult to manage weed commonly found in turfgrass and residential areas. We evaluated the efficacy of selected postemergence herbicides (glyphosate, dicamba, clopyralid, quinclorac, and triclopyr) on greenhouse-grown creeping bellflower. The experiment was conducted in Jan. 2016 and repeated in Sept. 2016. Each herbicide was applied at five rates plus a nontreated control. Clopyralid caused greater creeping bellflower biomass reduction and mortality than the other herbicides investigated. The herbicide dose required to cause 50% mortality was lowest for clopyralid [86–138 g·ha−1 acid equivalent (a.e.)] compared with dicamba (221–536 g·ha−1 a.e.), glyphosate (196–678 g·ha−1 a.e.), triclopyr (236–782 g·ha−1 a.e.), and quinclorac (>3000 g·ha−1 a.e.). Clopyralid could be an effective herbicide for managing creeping bellflower, although it is currently not registered for use in many habitats where this plant is a problematic weed.

Published: February 2018

This study estimates potential economic impacts of developing drought- and shade-tolerant bermudagrass (Cynodon dactylon) turf varieties in five southern states: Texas, Florida, Georgia, Oklahoma, and North Carolina. First, estimates are provided for the market-level crop values of the newly developed two varieties for each state. Then, an economic impact analysis is conducted using an input–output model to assess additional output values (direct, indirect, and induced impacts), value added, and employment due to the new varieties. Our results indicate that the two new varieties would offer significant economic impacts for the central and eastern regions of the United States. Under the assumption of full adoption, the two new products would generate $142.4 million of total output, $91.3 million of value added, and 1258 new jobs. When a lower adoption rate is assumed at 20%, the expected economic impacts would generate $28.5 million of output, $18.3 million of value added, and 252 jobs in the region. Our findings quantify the potential economic benefits of development and adoption of new turfgrass varieties with desirable attributes for residential use. The findings suggest that researchers, producers, and policymakers continue their efforts to meet consumers’ needs, and in doing so, they will also reduce municipal water consumption in regions suited to bermudagrass varieties.

Published: February 2018

Background: There is limited knowledge about perceived challenges during the transition to adulthood among immigrant youths who are originally from Arabic-speaking countries but now residing in Sweden. Aim: The aim of this study was to describe self-identified problems encountered by immigrant youths with disabilities from Middle Eastern countries who were living in Sweden during their transition to adulthood and to compare these descriptions to the problems identified by their caregivers.

Methods: Seventeen semi-structured interviews using the Canadian Occupational Performance Measure were conducted with 17 immigrant youths with intellectual disabilities aged 13-24 years and 16 caregivers, originally from Middle Eastern countries. The participants’ prioritized problems were categorized using the International Classification of Functioning, Disability and Health-Children & Youth Version, focusing on Activity and Participation.

Results: A difference in priorities during transition was found when comparing the youths’ and the caregivers’ views. Most of the youths’ priorities were identified in the chapter “Major Life Area” about basic economic transactions and seeking employment, whilst the caregivers thought their youths’ prioritized “self-care”.

Conclusion and implications for practice: Planning the best transition for immigrant youths with disabilities involves enabling them to identify their own preferences and needs while collaborating with caregivers and taking into consideration the cultural norms and traditions of collective caregiving.

From production inefficiencies to supply chain disruptions, management recognizes the need to rapidly evolve their family business to a professionally managed one. Their relationship-based supply chain worked for a family firm, but will this approach continue to work as they expand rapidly? A disruption in their egg supply exposed the firm to risks they never anticipated. Now, they are rethinking their entire supply chain, including their most important raw material: flour. How can they strategically manage their raw material needs while sustaining double-digit growth? How do they identify and mitigate risks in their chain? King’s Hawaiian knows its success is in its supply chain, including their unique delivery model. Getting this right is critical to their mission: to deliver their aloha spirit to every household, every day.

Published: February 2018

Introduction: Despite the increasing popularity of longitudinal primary care experiences in North America and beyond, there is a paucity of work assessing these medical undergraduate experiences using reliable and valid questionnaires. Our objective in this study was to evaluate a new preclerkship longitudinal family medicine experience (LFME) course at McGill University by assessing family physician preceptors’ self-reported ratings of the perceived effects of this course, and to compare their responses with ratings provided by medical students who completed the course.
Methods: This study is part of a larger evaluative research project assessing the first edition of the LFME. Students (N=187) and preceptors (N=173) of the 2013-2014 cohort were invited to complete separate online questionnaires in the spring through summer of 2014. The preceptor survey contained 53 items, 14 of which were nearly identical to items in the student survey (published elsewhere) and served as the basis for comparing preceptor and student ratings of the LFME.
Results: Ninety-nine preceptors (57% response rate; 55% female) and 120 students (64% response rate; 58% female) completed the surveys. Preceptors and students did not significantly differ in their overall ratings of the course, as both groups were satisfied with the quality of the LFME and felt it was an appropriate and valuable educational experience. However, preceptors had more positive ratings regarding their role and the benefits of the course than did medical students.
Conclusion: This study corroborates prior work showing extensive perceived benefits of longitudinal preclerkship exposure to primary care; however, preceptors were found to report more positive reviews of the course than students. This study also provides new innovative tools to assess students’ and preceptors’ perceptions of longitudinal, preclerkship family medicine courses available for use over time and in different educational contexts.

Published: February 2018

Conventional concrete aggregate consists of sand (fine aggregate) and various sizes and shapes of gravel or stones (coarse aggregate). However, there is a growing interest in substituting alternative aggregate materials, largely as a potential use for recycled materials. While there is significant research on many different materials for aggregate substitutes such as granulated coal ash, blast furnace slag or various solid wastes including fiberglass waste materials, granulated plastics, paper and wood products or wastes, sintered sludge pellets and others. Recycled waste glasses were used as coarse and fine aggregates replacement in concrete.  Coarse aggregates were replaced with Green Bottles coarse aggregates at third, half, two thirds, and 100% replacement ratios. The replacement of a third coarse aggregate was established as being the most suitable for retaining the properties of the concrete mix design. As for fine aggregates, in order to account for the numbers of variables and clearly establish a bench mark, the sand grading, color of glass, source of waste glass (bottles and non-bottles), and design mix strength were used as parameters. Fine aggregates from green, brown, and transparent bottles in addition to clear window waste glass were used. Concrete properties were tested in fresh and hardened states. The incorporation of glass sand regardless of the ratios of replacement showed no significant influence on fresh or mechanical properties of concrete except for the case of transparent bottles. Transparent bottles due to the wide source of obtainability have introduced a non-uniform factor that caused discrepancy compared to the rest of the group.
ANALYSIS OF POSSIBILITIES OF BIOMETRIC TECHNIQUES APPLICATION FOR CARRYING OUT DEPERSONALIZATION OF PERSONAL DATA
Authors: Antoshechkin Alexey Vyacheslavovich
Published: February 2018

The paper focuses on the problem of using biometric methods for the depersonalization of personal data. The analysis of the existing Russian and international legislative and regulatory framework for depersonalization has been carried out, and inconsistencies in the weakening of this concept have been revealed. In particular, it was found out that depersonalization of the personal data is not currently considered as a measure of their protection, personalized personal data are not treated as a category of personal data, depersonalization is considered a protection measure that is not directly related to measures to ensure the security of personal data, but not will disrupt the properties of their security. The analysis of requirements and methods for the depersonalization of personal data was carried out. There have been identified 5 necessary properties of impersonal data; 4 basic methods of depersonalization (introduction of identifiers, changes in composition and semantics, decomposition, mixing), and 3 main characteristics for the methods of depersonalization related to the security of personal data. The analysis elicited the presence or absence of the listed characteristics in each method of depersonalization of personal data. The problem of storing personal data has been considered, and the procedure of using a two-factor authentication based on biometric methods for working with personal data bases has been proposed. A method of depersonalization of personal data based on biometric procedures not supposing supply of confidential information via communication channels using cryptography has been proposed. To demonstrate the efficiency of the method there was given an example of reversible depersonalization using biometric techniques.

Authors: Ai Ping Ho , Lee Luan Ng
Published: February 2018

Language proficiency is one prominent factor that could affect the use of language learning strategies (LLSs) in learning English as a second language among the learners. The influence of language proficiency on the use of LLSs might differ as language learning has extended to the contexts of learning other than the learners’ differences. With that in view, this study seeks to examine various types of LLSs based on the language proficiency of 1699 learners in a Malaysia tertiary context. This study utilised the adapted version of Strategy Inventory for Language Learning (SILL, 1990) Findings revealed that high proficiency learners employed LLSs from high to medium level whereas average and low learners showed medium strategy use of all LLSs. One-way ANOVA tests further indicated that there were significant differences in the use of direct strategies based on their language proficiency. It was also found that language proficiency had a significant influence on the use of cognitive, compensation, social, metacognitive and affective strategies. Positive to mix variation of the high strategy use for individual items of SILL with significant differences were reported. Implications of this study were also discussed.
CHALLENGE OF READING AND UNDERSTANDING CONTEMPORARY FICTION
Authors: Sheikhzadeh Hossein , Sheikhzadeh Nazanin
Published: February 2018

Reading in the normal or general sense limits the possibilities of meaning, yet a text can be read for the plurality of meaning which is very evident in contemporary fiction. An author writes a text in order to throw it open to the reader whose activity produces meaning. Thus reading and understanding of a text is the result of the very subtle interaction between the text and the reader. In this sense contemporary fiction remains a sole exercise or activity of a reader. Complexity of the age in which we live makes this more challenging task for the reader. Since the author replicates his world of ideas from this complex world, this complexity and disintegration of recognizable truth, makes a deep crisis in art and society which is in flux.
La Seconde Sophistique et l’Antiquité tardive
Authors: Pernot Laurent
Published: February 2018

A Segunda Sofística e a Antigüidade tardia. Como os estudiosos ainda não tentaram estabelecer ligações entre a Segunda Sofística e a Antigüidade tardia, é preciso abrir um caminho, questionando-se em que medida o conceito de Antigüidade tardia pode ajudar a compreender de forma nova a Segunda Sofística. As duas principais vertentes da pesquisa sobre a Segunda Sofística consistiram, por um lado, em pôr em destaque a cultura dos so?stas e suas relações com o passado grego da época arcaica e clássica e, por outro, sublinhar a importância do papel político e social que os so?stas tiveram em sua época. A terceira vertente, que é proposta aqui, permite fazer surgir, na cultura e nas concepções dos so?stas dos séculos I-III d.C., as marcas que anunciam a Antigüidade tardia e que eram, na época, portadoras do futuro. A Segunda Sofística não se limitava à admiração pelo passado e pelas funções o?ciais exercidas pelos so?stas. Ela comportava também formas de devoção íntimas e exacerbadas, experiências de misticismo, um modelo de “holy man” dotado de poderes sobrenaturais, toda uma cultura ?losó?co-religiosa, relações com o platonismo, com o judaísmo e o cristianismo, e ainda uma prática literária rica e diversi?cada, que se estende, para além do discurso retórico, à poesia, à auto-biogra?a, à epistologra?a, à narração dos sonhos, ao romance
