The Hybridisation of Higher Education in Canada
Authors: Shale Douglas
Published: November 2016

Canada's postsecondary institutions are becoming increasingly involved with technology enhanced learning, generally under the rubric of distance education. Growth and activity in distance education stems from rapid developments in communication and information technologies such as videoconferencing and the Internet. This case study focuses on the use of new technologies, primarily within the context of higher education institutions operating in Canada's English speaking provinces. Capitalising on the interactive capabilities of "new" learning technologies, some distance education providers are starting to behave more like conventional educational institutions in terms of forming study groups and student cohorts. Conversely, new telecommunications technologies are having a reverse impact on traditional classroom settings, and as a result conventional universities are beginning to establish administrative structures reflective of those used by distance education providers. When viewed in tandem, these trends reflect growing convergence between conventional and distance learning modes, leading to the hybridisation of higher education in Canada.
Student Dropout at the Hellenic Open University: Evaluation of the Graduate Program, "Studies in Education"
Authors: Vergidis Dimitris , Panagiotakopoulos Chris
Published: November 2016

This study traces the root causes of dropout rates in one post-graduate course “Studies in Education,” offered by the Hellenic Open University (HOU). From our research findings, it was found that the main cause of dropping out stem from a combination of adult learners’ obligations, specifically balancing their academic workload with their employment commitments and family obligations (mainly for female students). The second reason for dropout rates among adult distance education learners include students’ miscalculation of the available time for studying and their underestimation of the extra effort required for effective learning. These reasons can be compared to the educational material, which, in general, was not considered overly difficult and did not appear to compel students to abandon their studies.

Redefining the cost and complexity of library services for open and distance learning
Authors: Parnell Stephen
Published: November 2016

Although most universities profess a belief that libraries are a key element in learner support, the full cost and complexity of providing quality library services to support open and distance education tend to be underestimated. It is argued in this article that this underestimation, in part, may reflect a lack of appreciation by faculty and university administrators of the role libraries play in the (distance) learning process. Within libraries and the education sector at large, there is also tends to be a lack of recognition of what portion of the costs of access to libraries and information are borne by other elements within universities, by external organisations, and by individual students. Three fundamental questions addressed are: Why is it necessary to determine the role of libraries in supporting learning? Who meets these costs? How institutionally independent should access to library and information services be? While it is to be expected that the level of costs incurred by different institutions will vary as they meet the library service needs of those who study in different modes, there are pedagogical, ethical, and quality issues that must be considered if the same academic award is to be made.

Measuring MBA Student Learning: Does Distance Make a Difference?
Authors: Kretovics Mark , McCambridge James A.
Published: November 2016

This article reports on an exploratory research effort in which the extent of MBA student learning on twelve specific competencies relevant to effective business performance was assessed. The article focuses on the extent to which differences in student learning outcomes may be influenced by one of three different types of instructional delivery: on-campus, distance, and executive MBA. It affirms the high quality of learning that can occur via distance education and proposes a strategy to conduct summative, program-level assessment. Specific findings include participants in all three groups self-reporting significantly higher scores on seven of twelve outcomes (e.g., goal setting, help, information gathering, leadership, quantitative, theory, and technology skills). It also notes that distance MBA students self reported significantly higher scores than on-campus students on the learning outcomes related to technology, quantitative, and theory skills, and higher scores on technology skills than the executive MBA group. Implications for further research are discussed.

Videoconferencing in Theatre and Performance Studies
Authors: Childs Mark , Dempster Jay
Published: November 2016

Previous reports in this series have indicated the growing acceptance of video-conferencing in education delivery. The current report compares a series of video-conferencing methods in an activity requiring precision of expression and communication: theatre and performance studies. The Accessing and Networking with National and International Expertise (ANNIE) project is a two-year project undertaken jointly by the University of Warwick and the University of Kent at Canterbury, running from March 2001 to March 2003. The project's aim is to enhance students' learning experience in theatre studies by enabling access to research-based teaching and to workshops led by practitioners of national and international standing. Various technologies have been used, particularly ISDN video-conferencing, computer-mediated conferencing, and the Internet. This report concludes that video-conferencing methods will gain acceptance in education, as academic schools themselves are able to operate commonly available technology the assistance of specialised service units.

Como se configura a comunicação online entre representantes e representados no Brasil? Um estudo sobre as ferramentas digitais da Câmara dos Deputados
Authors: Mitozo Isabele Batista , Marques Francisco Paulo Jamil , Mont'Alverne Camila
Published: November 2016

O artigo examina como se processa a comunicação entre a Câmara dos Deputados e os cidadãos brasileiros a partir do Portal da Câmara e do Portal e-Democracia. A análise considera a variedade e a profundidade dos mecanismos relacionados a três aspectos apontados pela literatura como fundamentais para as iniciativas patrocinadas: Informação, Transparência e Participação. A metodologia consiste em uma análise de conteúdo quantitativa, com aplicação de testes estatísticos para verificar a relação entre os portais e as variáveis que orientam o exame empírico. Partese da hipótese de que o Portal da Câmara é aquele que oferta mais Transparência, enquanto o Portal e-Democracia está mais atrelado ao provimento de Informação e de Participação, o que faz deles iniciativas complementares no âmbito da instituição. Partindo do pressuposto de que os portais possuem perfis distintos (priorizando, assim, recursos diferentes) é interessante perceber que, apesar de participação e educação legislativa caminharem juntas, 1) o Portal da Câmara é aquele que apresenta o maior índice de informação do tipo “educação legislativa”, em vez do Portal e-Democracia, no qual esse tipo de informação é inexistente; e 2) não há uma complementaridade intencional entre as duas iniciativas, que, embora pertençam à mesma Casa Legislativa, atuam de forma quase totalmente independente – não obstante os portais oferecerem ferramentas de caráter diferenciado

Sociedade dos Arquivos: Temporalidade e Intersubjetividade na Cultura Contemporânea
Authors: De Castro Fábio Fonseca
Published: November 2016

O artigo discute o conceito de arquivo na sociedade midiática e hiperconectada. Parte-se do conceito de traço, usado por Derrida (1967; 1995) para referir o caráter pré-ontológico de toda significação e caminha-se em direção a uma interpretação do traço por Ricoeur (1985), em sua compreensão fenomenológica do problema da temporalidade. Com esse horizonte, procuramos pensar a intersubjetividade e o sentido do debate sobre a “coesão à vida”, feito por Dilthey (1992a; 1992b), por meio do traço. Construímos a ideia de que a experiência espaço-temporal da cultura das mídias e, por meio delas, da sociedade contemporânea, é sem referentes e pautada pelo traço: atópica e acrônica, ela é, igualmente, anarquívica. De certa maneira, essa experiência abre possibilidades para abolir a submissão do pensamento a uma ordem analógica e, assim, para reverter o estatuto logocêntrico da cultura ocidental (Derrida, 1967).
An Analysis of Technical Efficiency for Household’s Rice Production in Cambodia: A Case Study of Three Districts in Battambang Province
Authors: Kea Sokvibol , Li Hua , Pich Linvolak
Published: November 2016

The aims of this study are to measure the technical efficiency (TE) of Cambodian household’s rice production and trying to determine its main influencing factors using the stochastic frontier production function. The study utilized primary data collected from 301 rice farmers in three selected districts of Battambang by structured questionnaires. The empirical results indicated the level of household rice output varied according to differences in the efficiency of production processes. The mean TE is 0.34 which means that famers produce 34% of rice at best practice at the current level of production inputs and technology, indicates that rice output has the potential of being increased further by 66% at the same level of inputs if farmers had been technically efficient. Furthermore, between 2013-2015 TE of household’s rice production recorded -14.3% decline rate due to highly affected of drought during dry season of 2015. Moreover, evidence reveals that land, fertilizer, and pesticide are the major influencing input factors of household’s rice production, while disaster, education of household head, family size and other crops’ cultivated area are core influencing factors decreasing TE. Conversely, the main influencing factors increasing TE are irrigated area, number of plot area and sex of household head.
Uridine Triphosphate Thio-analogues Inhibit Platelet P2Y12 Receptors and Aggregation
Authors: Guenduez Dursun , Tanislav Christian , Sedding Daniel , Parahuleva Mariana , Santoso Sentot , Troidl Christian , Hamm Christian , Aslam Muhammad
Published: November 2016

Platelet P2Y12 is an important ADP receptor that is involved in agonists-induced platelet aggregation and is an important target for the development of anti-platelet aggregation drugs. Here the effects of thio-analogues of uridine triphosphate (UTP) on ADP-induced platelet aggregation are characterised. Using human platelet rich plasma we demonstrate that UTP inhibits P2Y12 but not P2Y1 receptors and antagonises ADP-induced platelet aggregation in a conc.-dependent manner with an IC50 value of ~250 mM against ADP (10 mM). An 8-fold increase in the platelet inhibitory activity was observed with 2-thio analogue of UTP (2S-UTP) with an IC50 value of 30 mM. A 33-fold increase in anti-platelet aggregation activity was observed with 4-thio analogue (4S-UTP) with an IC50 value of 7.5 mM. However, a 3-fold decrease in activity was observed by introducing an isobutyl group at the 4S- position. A complete loss in anti-platelet aggregation activity was observed with thio-modification of gamma phosphate of the sugar moiety which yields an enzymatically stable analogue. The interaction of UTP analogues with P2Y12 receptors was further verified by P2Y12 receptor binding assay and cAMP assay. The novel data demonstrate for the first time that 2- and 4-thio analogues of UTP are potent P2Y12 receptor antagonists that can be useful candidates for therapeutic intervention.

Published: November 2016

A significant need exists to improve our understanding of the extent of greenhouse gas emissions from the storage of livestock manure to both improve the reliability of inventory assessments and the impact of beneficial management practice adoption. Factors affecting the extent and variability of greenhouse gas emissions from stored dairy manure were investigated. Emissions from six slurries stored in clean concrete tanks under identical “warm‐season” conditions were monitored consecutively over 173 d (18°C average air temperature). Methane (CH4) emissions varied considerably among the manures from 6.3 to 25.9 g m−2 d−1 and accounted for ∼96% of the total CO2 equivalent greenhouse gas emissions. The duration of the lag period, when methane emissions were near baseline levels, varied from 30 to 90 d from the beginning of storage. As a result, CH4 emissions were poorly correlated with air temperature prior to the time of peak emissions (i.e., the initial 48 to 108 d of storage) but improved afterward. The air temperature following the time of the peak CH4 flux and the length of the active methanogenesis period (i.e., when the daily CH4 emissions ≥ 7.6 g m−2 d−1) were highly correlated with CH4 emissions (R2 = 0.98, p < 0.01). Methane conversion factors (MCFs) ranged from 0.08 to 0.52 for the different manures. The MCFs generated from existing CH4 emission models were correlated (R2 = 0.68, p = 0.02) to MCFs calculated for the active methanogenesis period for manure containing wood bedding. A temperature component was added that improved the accuracy (R2 = 0.82, p < 0.01). This demonstrated that an improved understanding of lag period dynamics will enhance stored dairy manure greenhouse gas emission inventory calculations.

Core Ideas

CH4 emissions and MCFs from six dairy slurries varied despite identical storage conditions.

Postpeak CH4 emissions were more consistent among slurries compared with prepeak periods.

CH4 emissions represented ∼96% of the overall GHG budget.

N2O emissions were low but represented an 8× greater portion of the GHG budget for tie‐stall than free‐stall systems.
Exploring supply chain management practices within municipalities in the West Rand district
Authors: Marcus Ambe Intaher , Maleka Thabiso
Published: November 2016

This article explores supply chain management practices within selected municipalities in the West Rand district, Gauteng. An empirical research was conducted among supply chain practitioners in the municipalities based on the purposive sampling technique and the data were analyzed using descriptive statistics. The findings revealed that the municipalities have adopted and implemented supply chain management practices. However, supply chain management objectives are not always appropriately aligned with government policies, and the municipalities face serious supply chain issues such as leadership, lack of proper accountability and good governance. From the findings, it is evident that the lack of proper implementation of supply chain management in municipalities is the root cause of problems in service delivery in South Africa. It is recommended that municipal supply chain officials be empowered with supply chain skills for proper supply chain management execution.

Pioneer or imitate? An analysis of business imitations
Authors: Vusumuzi Nani Gwendoline
Published: November 2016

Pioneering is meant to create a competitive advantage for businesses and yet imitations are accelerating globally, leaving businesses not knowing whether to pioneer or imitate. The purpose of this study was to make an analysis of the benefits and costs of pioneering and imitation, with the aim of possibly helping businesses to decide on which route to take, after considering their strengths and weaknesses. This was a desk research study which analyzed literature on business imitation and pioneering. It focused on imitation driven by technology; be it in products or services with a bias towards legal innovative imitation. The analysis was primarily dominated by literature obtained from developed countries because of the rich pool of research output on both concepts. Based on the findings, the paper concludes that most businesses are innovative imitations and technology has facilitated most of these imitations. Recommendations are that businesses should adopt innovative imitation, but do so legally and ethically. There is also need for more research studies on business imitation in order to come up with strategies that will accommodate global players.

Resilience and Life Expectations of Perinatally HIV-1 Infected Adolescents in France
Authors: Funck-Brentano Isabelle , Assoumou Lambert , Veber Florence , Moshous Despina , Frange Pierre , Blanche Stéphane
Published: November 2016

Background:

Resilience of perinatally HIV-infected youth in European countries is poorly studied. Life satisfaction and expectations for adulthood are rarely examined.

Objective:

This cross-sectional, descriptive study of a French cohort of 54 perinatally HIV-infected adolescents raised in France (age 14-20 years) aimed to (1) evaluate their psychosocial adjustment, (2) identify their expectations for adulthood and (3) delineate risk and protective factors associated with mental health, life satisfaction, and HIV-1 viral load level.

Method:

Medical evaluation, psychological semi-structured interview, and self-report questionnaires were used.

Results:

All the adolescents had been receiving Highly Active Anti-Retroviral Therapy (HAART) for 9 to 11 years and 2/3 were healthy with controlled viral load (<50 copies/mL). The majority had medium to high levels of life satisfaction. They viewed HIV as having only minor impact on their current daily life and had positive expectations for adulthood. However, 46% exhibited psychiatric symptomatology. Multivariable analysis showed that having a deceased parent and current worries about HIV were substantial risk factors for psychiatric symptoms. Having two living parents and being satisfied with life were protective factors for mental health. Good quality of caregiver-adolescent relationships and high life satisfaction were significant protective factors for controlled viral load.

Conclusion:

These data indicate psychosocial resilience among perinatally HIV-1 infected adolescents with 10 years of HAART treatment. These findings demonstrate the influence of life satisfaction, parent’s life status and quality of caregiver-adolescent relationships on resilience and health outcomes in these patients. We conclude that healthcare providers should attend to these factors.
Prevalence of the Infertility Among Couples in Ouagadougou (Burkina Faso): a Population-based Survey
Authors: Eric Somé Nagaonlé , Justine Boncoungou , Jean Noël Poda
Published: November 2016

Background:

Worldwide, 10 to 15% of couples are infertile. In Burkina Faso, there has never been a population-based prevalence study regarding infertility.

Objective:

To determine the prevalence and risk factors of infertility in Ouagadougou (Burkina Faso).

Method:

We conducted a cross-sectional study with prospective data collection on 480 households from March to May 2014 in Ouagadougou. In each household, both the men and the women of childbearing-age were interviewed by an investigator using a questionnaire. The main outcome was infertile men or women living in Ouagadougou.

Results:

The participant-reported infertility prevalence was 9.3% (95% CI: 7.0; 12.2) and 10.4% (95% CI: 7.9; 13.5) for men and women, respectively. The primary and secondary infertility prevalence rates were 4.8% (95% CI: 3.2; 7.2) and 4.4% (95% CI: 2.9; 6.7) respectively for men and 6.8% (95% CI: 4.8; 9.4) and 3.6% (95% CI: 2.2; 5.7) for women. Considering only infertile participants, primary infertility concerned 52.3% (95% CI: 37.2; 67.0) and 65.3% (95% CI: 50.6; 77.6) of men and women respectively.

The medically-diagnosed infertility prevalence was 2.9% (95% CI: 1.7; 4.9) in both men and women groups. The male and female-related infertility represented 35.7% (95% CI: 13.7; 66.0) and 42.9% (95% CI: 18.3; 71.6) of the cases respectively and the dual-factor-related infertility 21.4% (95% CI: 5.9; 54.0).

Conclusion:

Though lower than the global and Sub-Sahara African region’s prevalence, the infertility prevalence in Ouagadougou was still high. Compared to previous data in the same country, we saw a shift from predominant secondary infertility to predominant primary one. Infections remained the leading cause of infertility.

THE IMPACT OF TREATMENT WITH GLIMEPIRIDE CONTENT OF CERTAIN ADIPOSE TISSUE HORMONES AND CYTOKINES IN PATIENTS WITH NEWLY DIAGNOSED TYPE 2 DIABETES
Authors: Urbanovych A. M.
Published: November 2016

The aim of the research was to study the effect of the drug glimepiride on adipose tissue hormones levels (leptin, resistin) and cytokines (IL-2, IL-6, TNF-α) in type 2 diabetes. 28 patients with newly diagnosed type 2 diabetes were examined before and after 12 months of hypoglycemic glimepiride monotherapy. The results indicate that the normalization of carbohydrate metabolism, cytokines levels after the treatment is caused not only by the direct influence of glimepiride in β-cells of the pancreas, but also by its ability to modulate the secretion of proinflammatory cytokines.

Published: November 2016

AbstrakKebutuhan akan listrik akan terus meningkat dari tahun ke tahun, hal ini dikarenakan pembuatan produk yang menggunakan listrik sebagai energi nya juga gencar dikeluarkan oleh produsen sehingga kebutuhan akan listrik sudah menjadi kebutuhan yang sangat vital untuk masing-masing individu. Saat ini di negara kita telah dikembangkan listrik prabayar disamping listrik pasca bayar yang telah berjalan, fungsi dari listrik prabayar ini adalah untuk dapat mengontrol penggunaan dari listrik itu sendiri. Namun, penggunaan listrik prabayar tidak sepenuhnya digunakan secara optimal oleh pelanggan, dikarenakan pelanggan tidak mengetahui beban dari alat listrik yang digunakan sehingga tidak dapat melakukan kontrol dari pulsa listrik yang dibeli. Dari permasalahan itu peneliti mengusulkan untuk membuat suatu alat kontrol dengan menggunakan arduino uno sehingga pemilik dapat mengontrol penggunaan listriknya secara real time. Board Arduino berfungsi sebagai sistem kontrol pengambilan data, sebelum data tersebut di olah pada server. Terdapat sistem sensor berfungsi untuk pengambilan data ampere yaitu sensor AC712-20A dan modul relay sebagai saklar elektrik berfungsi untuk memutus daya listrik ketika pulsa tidak mencukupi. Dari hasil pengujian yang telah dilakukan, terdapat kesalahan pengukuran rata-rata sensor ACS712-20A dengan multitester sebesar 26%, sedangkan untuk pengukuran billing listrik prabayar terdapat kesalahan sebesar 6%.
Factors controlling keyhole-induced porosity in cold wire laser welded aluminum
Authors: Ola O. T. , Doern F. E.
Published: November 2016

Production of lightweight laser-welded assemblies to meet the requirements for higher performance and reduction of carbon emission requires substantial effort in mitigating the effects of processing on welding defects. The factors controlling keyhole-induced porosity during cold wire laser welding of AA6061-T6 were studied. The laser beam intensity distribution parameters and the laser energy deposited per unit length of the weld determine the keyhole behavior, the shape and size of the surrounding molten material and, consequently, the percentage of porosity and average size of pores that resulted from keyhole collapse during welding. Changes in keyhole size and porosity are not noticeably significant with respect to the rate of feeding the cold wire into the molten weld pool. The vapor plume that forms above the molten pool due to the ejection of evaporated metal particles from the keyhole effectively attenuates the laser beam and reduces the depth of penetration. However, the erratic behavior of the plume results in an inconsistent porosity response. The use of a gas jet for deflecting the plume is beneficial for more consistent porosity response. Results from this work provide guiding principles for the selection of process variables for keyhole-mode laser welding of aluminum alloys, depending on the particular application and the criteria for acceptable level of defects.

When wells with formation temperature above 180 °C are fractured conventionally, a large amount of water has to be pumped down ahead of time to cool down the formation, and also conventional fluids have to be stretched to the extreme limits of performance. The fractures obtained this way are often unsatisfactory. We have developed a new fracturing fluid which can be used for high temperature wells up to 230 °C without the need of cool-down.

This fracturing fluid is simply composed of a specially designed synthetic polymer as the gelling agent, a metal crosslinker such as a zirconium complex, a multi-functional environmentally friendly additive, and an oxidizing breaker. The fluid can be prepared in the same way as conventional guar fluids. Made in an invert emulsion form, the gelling agent hydrates quickly, allowing for on-the-fly operation with no need of extra hydration equipment and time. With the unique combination of the environmentally friendly additive and the zirconium crosslinker, the crosslinking of the system is well delayed and controlled as well as the stability of the fluid is satisfactorily maintained at high temperatures. More interestingly, the spike of the apparent viscosity at the early stage of crosslinking is nicely damped, leading to a "flat" viscosity profile. Low concentrations of the gelling agent are needed for the fluid systems. Low concentration of gelling agent and controlled delay of crosslinking lead to maximally reduced friction pressure. The fluid can be broken by the oxidizing breaker in a controlled way. Free of typical residues associated with guar-type fracturing fluids, the post-frac cleanup of this fluid is more complete. Lab data of hydration, rheology, retained conductivity, etc. will be presented and discussed.

Horizontal wells with multi-stage fracturing have been proved to be an efficient technology to exploit thin-interbed reservoirs. However, problems were encountered during multi-stage fracturing of horizontal wells in the Silurian reservoir in Ta-zhong Oilfield, western China. This paper mainly discussed the causes of these problems and the optimized completion and fracturing designs to avoid these problems.

Ta-zhong Silurian reservoir is a thin-interbed, low-permeability reservoir with buried depth from 4000 to 4500m. The sand distribution is heterogeneous both vertically and horizontally. A horizontal well in this reservoir was fractured twice using two different multistage fracturing technologies, firstly hydraulic jetting fracturing and then packer-segregated fracturing. Abnormal pumping pressure and difficulties to add proppants were encountered in both of the two operations. The causes to these failures will be analyzed comprehensively, based on which an optimized multi-stage fracturing design of this well will be proposed through numerical modeling and analysis.

According to the analysis, defective completion and fracturing design is the main cause of the failures experienced in the two operations. The ill-considered jetting parameters caused the difficulties of fracture propagation and proppant placement during the hydraulic jetting fracturing treatment, whereas inappropriate perforating intervals led to simultaneous initiation of multiple fractures in each stage during the packer-segregated fracturing treatment. These fractures interfered with each other and led to great near-wellbore pressure losses and fracture reorientation, and then resulted in abnormally high pumping pressure and challenges of proppant placement. Several changes to avoid these problems are proposed and incorporated in a new multi-stage fracturing design. The jetting parameters, fracture spacing, fracture geometries as well as perforation parameters are all optimized by numerical modeling in the new design of well A and other horizontal wells in Ta-zhong Silurian reservoir, which is expected to avoid the above-mentioned problems and obtain better results.

Nowadays, horizontal wells with multi-stage fracturing are a common-used technology in tight thin-interbed formations. However, the design of segregated completion and multi-stage fracturing is still a challenge for such formations. This paper introduced the lessons learned from a failure case and proposed an optimized completion and fracturing design, therefore provided a good reference for completion design of the wells in Ta-zhong Silurian reservoir as well as similar reservoirs in the world.
Vertical Well Completions in Multilayer Reservoirs: A Decade of Technologies Implemented in Argentina

Published: November 2016

Many fields in Argentina have multilayer reservoirs that require various stimulation techniques, mainly hydraulic fracturing. A variety of formations and types of reservoirs, such as conventional (mature fields) and unconventional (tight gas and shale), are present in the Golfo San Jorge and Neuquen basin. The hydraulic fractures created in these basins present a variety of conditions and challenges related to depth, well architecture design, bottomhole temperature (BHT), reservoir pressure, and formation permeability.

In the last decade, new technologies were introduced and developed to help achieve greater efficiency and reduce time and costs associated with completions for these fields. This paper presents experiences gained using two types of technologies.

First, a new conventional straddle-packer system (SPS) was used in conjunction with a workover unit, which was part of a technological collaboration agreement between an operator and service company. It was mainly applied in conventional reservoirs, mature fields, in wells with up to seven fracture stages, and in new or recompletion wells. Second, a pinpoint technique was used, called hydrajet perforating annular-path treatment placement and proppant plugs for diversion (HPAP-PPD). This technique was applied in new wells (rigless completion) and all types of reservoirs, both conventional and unconventional (tight gas and shale), and allowed performing up to 30 separate fracture stages in a single well, with three stages completed in a 12-hr operation.

These completion methods allowed operators to focus treatments in desired zones with specific treatment designs based on reservoir characteristics. Several case histories are presented for different basins, formations, and reservoirs types, as well as lessons learned and completion time reductions.
Reliable Reconstruction of a Macrovelocity Model via Reflected Full Waveform Inversion with Modified Cost Function

Published: November 2016

The paper develops a reliable numerical method to solve inverse dynamical problem of seismic waves’ propagation on the base of nonlinear least squares formulation which is widely known as Full Waveform Inversion (FWI). The key issue on this way is correct reconstruction of macrovelocity component of the model with input seismic data without time frequencies less than 5 – 7 Hz and reasonable source – recievers offsets. To provide correct macrovelocity reconstruction we modify regular nonlinear least squares formulation used in standard versions of FWI by decomposing the model space into two subspaces

slowly varying in space functions (propagators p) which do not change direction of propagation of seismic energy, but governs travel times; sharply changing in space functions (space reflectivity r) which do not change travel time, but turn propagation direction towards acquisition.

In turn this reflector is represented as application of migration operator to new unknown called time reflectivity s connecting with space reflectivity by migration operator M(p):

This decomposition modifies the cost function in the following way:

which opens the possibility to implement minimization with respect to propagator and reflectivity as two different step-by-step processes.

We present results of comparative analysis of numerical Singular Value Decompositions for both cost functions which reveal much more sensititve of the modified one with respect to the perturbation of a space of propagators.

We use the modified cost function to do the FWI for well known Marmoussi2 dataset. The numerical results are presented and discussed.
Generating Electricity Using Co-Produced Brine from Oil & Gas Wells Evaluating Prospect in Mehsana Asset North Cambay Basin Gujarat

Historically, the co-softhyphen;produced hot water has been an inconvenience and a disposal issue for oilfield operators. This paper focuses on brine or coproduced fluids (hot aqueous fluids produced during oil and gas production) as a potential source for electricity generation, which could be produced from the thermal energy available in the produced fluid. Oil and Gas (O&G) industry today is in possession of thousands of established wells with known temperatures and flows which can be used for producing emissions-free and cost-competitive electricity using binary cycle units.

Power generation from coproduced fluids using a binary-cycle power plant is underway at the Rocky Mountain Oilfield Testing Center in Wyoming and being considered in locations in Texas, Louisiana, Florida, and Arkansas. Although currently there is no electricity generated from coproduced fluids in India, various studies, suggest that the oil and gas fields in the Cambay Basin basin have a promising geothermal gradient of 35-40 °C/km, while (Chakravorty et.al, 2008) reports around 88% water cut for production from Jhalora Oilfield in Mehsana Asset, North Cambay Basin. This combination of favorable geothermal gradient and large volume of water produced is promising for electricity generation from these coproduced fluids.

In this paper, we studied and collated data of Jhalora Field in Mehsana asset of Cambay Basin for coproduction electricity generation and attempt to provide an estimate of the coproduced-water-electricity-generation potential of that field using two different approaches.

The most significant parameters to economic viability for such a project include reservoir temperature as well as total fluid production rate. The reservoir temperature of Jhalora Field is 90-100°C and with produced water flow rate of 5096m3/day, it is a suitable candidate for application of this technology.
