Published: October 2017

Abstract
Risks are inherent practically in all sphere of oil and gas production: from geological exploration works on oil and gas to industrial development of reserves. But it is not enough to study only risks, we often face insufficiency of knowledge of variety of manifestations of geologic-geophysical trade properties of the studied object. It is especially important to consider risks and uncertainty at the initial stages of geological field works. Studying of geological risk, arising at estimation of oil reserves became a subject of our research. The work process was divided into some stages: 1) Choice of significant geological field parameters, 2) Definition of variable property manifestations factors of the studied geological field parameters, 3) Multiple modeling of the studied processes, 4) Creation of Tornado plot
For further work, the analysis of an assessment of risks at reserves estimation was chosen as a probabilistic method. It was chosen hypothetical fields which subcalculating parameters, were collected in tables
Using the data provided to the table, we make Tornado Plot extent of influence of geological risks is visually shown in the made matrix.
The made matrix reflects degree of risks in an assessment of subcalculating parameters and their influences on resultant indicators. The vertical scale reflects risk, which is classified on low, average, high. Using the results received in the analysis of uncertainty and a scale of influence of parameters on resultant indicators and a scale of level of risks, geological field parameters were located on the constructed matrix. From the received matrix, it is visible that among the taken parameters the greatest risk and high level of influence renders porosity. Therefore, the bigger attention at calculation of stocks and creation of geological and mathematical model has to be paid to this parameter.

Published: October 2017

Abstract
The production experience from the Statfjord Field on the Norwegian Continental Shelf is one of the greatest adventures in modern oil and gas history. After achieving very high oil recovery factor using a predominant drainage strategy with pressure maintenance by water and gas injection, the drainage strategy in the field has since 2007/2008 been changed to reservoir depressurization.
Prior to depressurization start-up, the field has produced about 652 million Sm3 (4.1 billion bbl) oil and 187 billion Sm3 gas. Currently, the field is producing at an oil rate of approximately 5 300 Sm3/d and a gas rate of about 11 million Sm3/d. Estimates indicate that successful implementation of the new drainage strategy will continue and lead to an ultimate oil recovery of higher than 67% and a significant additional gas production, as a result of the depressurization process. In addition, the field life will be extended from 2009 to 2025, and this will contribute to lifetime extension of the attached satellite fields.
The main purpose of this paper is to provide a description of the multidisciplinary approach used for evaluation and planning of the Statfjord Late Life (SFLL) with reservoir depressurization, share learnings from depressurization start-up and address challenges, uncertainties and opportunities.
Power Interconnection between two Existing Deepwater FPSOs - A Key Enabler for Production Increase
Authors: Leforgeais Bruno , Tayat Faradj 
Published: October 2017

Abstract
The first-ever power interconnection between Deep Offshore floating units, i.e Girassol and Dalia FPSOs, including retrofit of existing power generation and integration of an overall Power Management System, has enable the implementation of subsea multiphase pumping to activate the existing production loops.
Despite gas lift activation at riser base, the back pressure generated by pressure drop in the subsea network was limiting the liquid production of the high productivity wells. Providing a pressure boost in the production network using the subsea multiphase pumps enabled to lower the well head pressure, thus increasing production rates and ultimate recovery.
The paper will present the miscellaneous technical challenges that have been faced during the project development from the early design stage down to commissioning, start up and operation of both FPSOs as an integrated asset while maintaining and enhancing the full oil and gas production.
It will cover both surface and subsurface aspects with the design and implementation of power generation upgrade, electrical network modifications, overall power management system involving load sharing and load shedding as well as the interconnecting power cable with specific dynamic sections and the power supply and integration of the subsea multi phase pumps with an offset up to 18 km.
Practical Staged Implementation of Digital Field with Short Term Benefits
Authors: Gauder Denis , Koloskov Mikhail , Dmitry Sukhamera 
Published: October 2017

Abstract
The digital oilfield technology is typically associated with high level of field automation and instrumentation, as well as advanced petroleum engineering modelling.
This paper discusses the application of digital oilfield to large brown fields based on real, but anonymous cases, where the level of instrumentation is low, production models might not be available, and the local expertise might be limited.
In such situation, the principles of digital oilfield need to be adapted. This paper presents a staged implementation methodology, where the benefits and costs can be evaluated at every step of the project, allowing to build a system with the right amount of functionality and complexity.
The first step focuses on improving data quality, even if the data is captured manually, through automated quality checks and raising awareness during the data capture process. The second step focuses on automating routine tasks, such as reporting, leading to efficiency improvement, but also increased accuracy and traceability of the reported figures. The third step focuses on developing a production monitoring platform, allowing to perform exception-based surveillance, particularly important for large fields, as well as providing a single point of access for different disciplines, hence acting as a collaborative environment. At last, the model-based more complex workflows are discussed, such as virtual metering, production optimization and short-term production forecasting.
The main conclusion of this paper is that the Digital Oilfield can deliver value for brown fields, even if they are close to their life end. The relatively low cost of these solutions, and the immediate benefits they can provide makes it meaningful, even in a short-term perspective. A staged implementation lowers both the project risks and the required initial investment, while easing the adoption process by the users.
The main differences with application to green fields is an increased focus on data quality improvement, and a lower focus on models and complex engineering workflows. The surveillance platform should also focus more intensively on exception based surveillance, allowing to pre-process large amounts of data, rather than providing extremely fine detail.

Authors: Nguyen Amanda Phoon , Frydrych Agnieszka M 
Published: October 2017

Introduction:Oral leiomyomas are rare, benign neoplasms of smooth muscle origin, presenting as a solitary, asymptomatic, nodular mass.Case Presentation:Here we present the case of a 54-year-old male with a lesion in the midline of his hard palate, which was diagnosed as a localized benign leiomyoma, along with a review of the recent literature.Discussion:Diagnosis of a leiomyoma must be based on the histopathological assessment of tissue as the clinical appearance is non-specific. The peak prevalence of head and neck leiomyoma is observed in the 4thand 5thdecade of life with uncertain gender predilection. Histological features include interlacing fascicles of smooth muscle small cells with eosinophilic cytoplasm. Complete excision is usually curative and recurrence is rare.Conclusion:Due to their rare nature, it is important that cases of oral leiomyoma can be reported in the literature to improve our understanding of this entity.

Background:The BD FACSPresto™system uses capillary and venous blood to measure CD4 absolute counts (CD4), %CD4 in lymphocytes, and hemoglobin (Hb) in approximately 25 minutes. CD4 cell count is used with portable CD4 counters in resource-limited settings to manage HIV/AIDS patients. A method comparison was performed using capillary and venous samples from seven clinical laboratories in five countries. The BD FACSPresto system was assessed for variability between laboratory, instrument/operators, cartridge lots and within-run at four sites.Methods:Samples were collected under approved voluntary consent. EDTA-anticoagulated venous samples were tested for CD4 and %CD4 T cells using the gold-standard BD FACSCalibur™system, and for Hb, using the Sysmex®KX-21N™analyzer. Venous and capillary samples were tested on the BD FACSPresto system. Matched data was analyzed for bias (Deming linear regression and Bland-Altman methods), and for concordance around the clinical decision point. The coefficient of variation was estimated per site, instrument/operator, cartridge-lot and between-runs.Results:For method comparison, 93% of the 720 samples were from HIV-positive and 7% from HIV-negative or normal subjects. CD4 and %CD4 T cells venous and capillary results gave slopes within 0.96–1.05 and R2≥0.96; Hb slopes were ≥1.00 and R2≥0.89. Variability across sites/operators gave %CV <5.8% for CD4 counts, <1.9% for %CD4 and <3.2% for Hb. The total %CV was <7.7% across instrument/cartridge lot.Conclusion:The BD FACSPresto system provides accurate, reliable, precise CD4/%CD4/Hb results compared to gold-standard methods, irrespective of venous or capillary blood sampling. The data showed good agreement between the BD FACSPresto, BD FACSCalibur and Sysmex systems.
Association of Kidney Transplantation with Survival in Patients with Long Dialysis Exposure
Authors: Rose Caren , Gill Jagbir , Gill John S. 
Published: October 2017

Background and objectives
Evidence that kidney transplantation is associated with better survival compared to dialysis stems from data in populations with short durations of dialysis exposure. Recent changes in allocation policy increase access to transplantation for patients with longer dialysis exposure. The objective of this study was to determine the association of transplantation with survival in patients with ≥10 years of dialysis treatment.

Design, setting, participants, & measurements
Our study of n=5365 patients in the Scientific Registry of Transplant Recipients determined the adjusted relative risk of death in recipients of a deceased donor kidney transplant after ≥10 years of dialysis treatment compared with waitlisted patients with the same dialysis exposure in a time-dependent nonproportional hazards analysis.

Results
The adjusted relative risk of death in n=2320 transplant recipients compared with patients on dialysis who had equal lengths of follow-up from their 10-year dialysis anniversary was 0.60 (95% confidence interval, 0.53 to 0.68), and this benefit was observed in a variety of patient subgroups, including patients ≥65 years of age and patients with diabetes. However, transplant recipients were at higher risk of death for 180 days after transplantation and did not derive survival benefit until 657 days after transplantation, despite receiving good-quality kidneys. The study patients were younger and had higher expected post-transplant survival than patients currently waitlisted with ≥10 years of dialysis.

Conclusions
Transplantation is associated with better survival in patients who were actively waitlisted with dialysis exposure ≥10 years. Whether transplantation is associated with better survival in currently waitlisted patients with similar dialysis exposure and whether transplantation of lower-quality deceased donor kidneys is associated with better survival are uncertain.
Un discurso de modernidad y tradiciónVerna Cook Shipway y la representación de la casa mexicana
Authors: Ettinger McEnulty Catherine R. 
Published: October 2017

El presente artículo aborda como temática una serie de cinco libros sobre la casa mexicana publicados entre 1960 y 1970 en los Estados Unidos. Al considerar su im-portancia por la circulación que tuvieron tanto en México como en el extranjero, se plantea una revisión cuidadosa de sus contenidos: localidades, propietarios, arquitectos y rasgos de las casas presentadas. A partir de este estudio, y de una reseña de la vida profesional de la autora principal (Verna Cook Shipway), se concluye que el formato (fotografías, dibujos y breves leyendas) prolongó una tradición existente de libros sobre arquitectura mexicana gestadas en el extranjero, además, el contenido, el énfasis en el trabajo artesanal, los espacios de transición y la vegetación tropical, los patios interiores como evidencia de la intimidad y aislamiento, entre otros, mostraban una inquietud de la autora, en particular, y de su público –en general extranjero– por rechazar la modernidad. En este sentido, los libros presentan no sólo casas, sino un retorno a valores tradicionales, y representan para los lectores la posibilidad de otra manera de vivir residencial en México con la llegada de jubilados extranjeros al país.

Published: October 2017

O uso de plantas medicinais é muito difundido no Brasil, este meio terapêutico pode ser muito eficiente, contudo sua administração deve ser realizada com cautela. Todos os dias, pessoas procuram auxílio médico com sintomas de intoxicação por ingestão de compostos provenientes de ervas consideradas curativas e não são raros os casos de óbito relacionados ao uso dessas substâncias. Para garantir o uso seguro das plantas medicinais deve-se submetê-las a testes de citotoxicidade e mutagenicidade, porém pouco foi estudado nesse sentido.Comumente para realizar essa testagem, os pesquisadores lançam mão de bioindicadores que podem ser bactérias, microcrustáceos, insetos e vegetais como é o caso do Sistema Teste Allium cepa, cujo nome vulgar é cebola. Este último sistema é considerado pela literatura como o bioindicador ideal da citogenotoxicidade de infusões de plantas medicinais, pois possui confiabilidade comprovada através de certificado em órgãos internacionais, é um item universal, de baixo custo, cultivável o ano todo, possui rápido desenvolvimento de células e cromossomos grandes.A metodologia do Sistema Teste Allium cepa é simples e de fácil execução. Essas características o elegem como o instrumento preferido pela comunidade científica para um primeiro screening da citogenotoxicidade de infusões de plantas medicinais.
Varastettu kuolema (1938) poliittisena elokuvana
Authors: Seppälä Mikko-Olavi 
Published: October 2017

Artikkeli tarkastelee Nyrki Tapiovaaran ohjaamaa elokuvaa Varastettu kuolema (1938) poliittisena kommenttina 1930-luvun vasemmistolaisen aktivismin ja etsivän keskuspoliisin väliselle jännitteelle. Artikkelissa analysoidaan elokuvan roolien miehitystä ja esitetään siitä uutta tietoa erityisesti suhteessa Työväen Näyttämö -nimiseen harrastajateatteriin. Artikkeli osoittaa, että Tapiovaara haki rooleihin osuvia ”tyyppejä”, joiden siviiliroolilla – taustalla tai henkilöhistorialla – oli merkitystä roolivalinnassa. Erityisen selvästi tämä näkyy entisten punavankien, tuomittujen kommunistien ja fasisminvastaiseen taisteluun sitoutuneen teatteriryhmän jäsenten kiinnittämisellä sotilaiden, santarmien ja salaisen poliisin rooleihin. Viittaukset esiintyjien siviilirooliin tai ohjaaja Tapiovaaran omaan henkilöön saivat tilaa elokuvassa pienissä yksityiskohdissa. Varastettu kuolema leikittelee useilla kaksoisvalotuksilla. Ennen muuta se rinnastaa 1900-luvun alun sortokauden 1930-luvun poliittisen tilanteen kanssa ja luo henkilökuvaukseen uusia tasoja tarkkaan harkitulla roolituksella. Ironinen tunnistaminen ruokkii katsojaa irrottautumaan historialliseen tarinaan eläytymisestä osoittamalla yllättäviä, usein nurinkurisesti kuvattuja yhtymäkohtia elokuvan tekoajan yhteiskunnalliseen todellisuuteen.
Paluu Hoikkaan

Televisiosarja Metsolat saavutti aikanaan suuren suosion 1990-luvun Suomessa. Tutkijat selittivät sarjan miljoonayleisöä etenkin sillä, että sen nostalginen maaseutumiljöö puhutteli talouslamasta kärsivää kansaa. Keskustelussa Metsoloita tulkittiin lähinnä symbolisella tasolla, jolloin sarjan sosiaaliset merkitykset jäivät huomioimatta.
Sosiaalityötä ja kulttuurintutkimusta yhdistävä artikkeli palaa Metsoloiden pariin ja avaa uuden näkökulman sen merkityksiin. Huomion keskiössä ovat nyt sarjan poikkeuksellisen monipuoliset vaikeuksien voittamisesta kertovat tarinat eli selviytymistarinat. Kerronnalliseen tutkimusperinteeseen kiinnittyen aineiston selviytymistarinat ymmärretään artikkelissa kulttuurisiksi mallitarinoiksi, joilla on seurauksensa todellisten ihmisten arjelle. Siksi sarjan tarinat tulee myös ottaa vakavasti. Artikkeli keskittyy analyysissään Metsoloiden kahden keskeisen henkilön, Erkki Metsolan ja Risto Metsolan, tarinoihin. Erkin ja Riston selviytymistarinoiden avulla pohditaan, miten selviytymisen ilmiö rakentuu sarjassa ja mistä elementeistä tuo selviytyminen koostuu.
Artikkelin mukaan Metsoloiden selviytymistä ei voida jäljittää vain tiettyyn tarinatyyppiin kuten sankaritarinaan. Sen sijaan sarjan selviytymisessä on kyse jatkuvasta elämänkulun prosessista. Artikkeli tuo esiin kulttuuristen selviytymistarinoiden inhimillisyyden ja osoittaa siten vuosikymmenten takaisen televisiosarjan ajankohtaiset ja universaalit merkitykset.
La escuela no es una empresa, ni la educación un negocio
Authors: Espinosa Gómez Deyby Rodrigo 
Published: October 2017

El presente artículo propone una reflexión crítica sobre la influencia del discurso empresarial en la escuela, el cual considera a la educación como un bien esencialmente privado y cuyo valor es ante todo económico. Hoy no cesa de escucharse cómo conceptos propios del mundo empresarial y mercantil se adhieren a la educación: «calidad», «competencias», «indicadores», «excelencia», «estándares», «evaluación por resultados», «pruebas estandarizadas», «oferta y demanda», «cliente y servicio», etc. Esto ha hecho que se sobrevalore esta clase de conceptos y no a la educación misma; es decir, los conceptos empresariales se usan como expresión genérica y como única verdad para caracterizar la educación. En ese sentido, en primer lugar, se expondrá las trampas, efectos y consecuencias de uno de los conceptos ori­ginarios del mundo empresarial como lo es el de calidad de la educación. En segundo lugar, surge la necesidad y la urgencia de develar prácticas alternas en defensa de una escuela que recupere la educación como valor social.
