Deep High-Pressure Completions: A Case History Offshore Gulf of Mexico
Authors: Carpenter Chris
Published: August 2017

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 181557, “Pushing the Completion Design Envelope in Ultradeepwater: Design, Installation, and Performance of Deep High-Pressure Completions—A Case History of the Gunflint Development, Offshore Gulf of Mexico,” by Jack Sanford, SPE, John Healy, SPE, Tim Hopper, SPE, Josh Fink, SPE, Ladd Grammer, SPE, James Koy, SPE, Jocelyn Perroux, SPE, Ian Magin, SPE, Kevin Williams, and Tom Seeley, Noble Energy, prepared for the 2016 SPE Annual Technical Conference and Exhibition, Dubai, 26–28 September. The paper has not been peer reviewed.

A Gulf of Mexico case history is presented describing the successful delivery of two deep high-pressure high-rate-designed oil wells in an ultradeepwater environment. Well conditions, coupled with challenging production requirements (depletion of 10,000 psi), posed an arduous design challenge. More than two dozen firsts for the operator, and indeed for the industry, were required to deliver the final completion designs. 

Introduction

The Gunflint field is located in five Mississippi Canyon blocks in approximately 6,100 ft of water. The discovery well (MC948 2) was drilled in 2008. The field contains stacked Middle Miocene age reservoirs between depths of 23,800 and 27,000 ft true vertical depth subsea. A mixture of black oil, rich gas condensate, and dry gas has been penetrated in seven reservoirs. Only three oil reservoirs, Green B, Green C, and Blue E, are considered commercially viable for development. Reservoir pressures and temperatures range from 17,000 to 19,000 psi and from 210 to 240°F, respectively. Petrophysical analysis determined that the primary reservoir sands are high-quality sandstones with good permeability.

The development plan consists of two subsea wells tied back to the Gulf Star I platform. The first well (G4, the “Blue” well) is a twin to the original discovery well in the top of the structure and targets the Blue E horizon as a single completion.  The second well (G2, the “Green” well) is a sidetrack of the original discovery well targeting the Green B and C reservoirs in a dual commingled smart completion. 

Initial well productivity was designed for 15,000 BOPD for the Blue well and 20,000 BOPD from the commingled Green well. Instantaneous initial total oil potential is expected to be between 30,000 and 35,000 BOPD, and each well will have a dedicated 6-in. pipeline for flowback to the host facility. However, the expected total field plateau rate is 25,000 BOPD owing to capacity limits at the remote host. Specifically, the project’s statement of requirements stipulated that G4 was to deliver a production capacity of 15,000 BOPD at a skin (production efficiency) of less than 3, while G2 was to deliver a production capacity of 20,000 BOPD (combined) at a skin (production efficiency) of less than 3.

Authors: Hamuaty Rambu Beppy , Sukmawati Indriyanti Rafi , Sandra Ferry
Published: August 2017

Background: Interaction between advanced glycation end product (AGE) and receptor for AGE (RAGE) triggers the escalation of inflammatory cytokine expressions. High-sensitivity C-reactive protein (hsCRP), an important inflammatory marker, has been reported to be modulated by soluble RAGE (sRAGE). However, the relationship between hsCRP and sRAGE in diabetes was not clearly described. Therefore present study was conducted to determine the relationship between sRAGE with hsCRP in men with central obese diabetic and non-diabetic. Materials and Methods: Adult men aged 25-60 years with central obese diabetes and non-diabetes, were recruited. Patient’s profiles were collected before the physical and blood examination. Physical examinations were conducted by measuring waist/abdomen, blood pressure, height, and weight. The routine blood test was performed to obtain concentrations of fasting blood glucose, HbA1c, hsCRP and sRAGE level.Results: Fifty-seven subjects with central obese and waist size ≥90 cm were selected. It was found that hsCRP values were significantly different (p=0.000) in HbA1c <6.5% dan HbA1c ≥6.5% groups. There was an inverse relationship between hsCRP and sRAGE levels for both in HbA1c <6.5% (r=-0.073) and HbA1c≥6.5% (r=-0.022) groups. In HbA1c ≥6.5% group, sRAGE showed strong positive correlation with 1 mg/dL ≤ hsCRP <3 mg/dL group (r>0.5).Conclusions: In the early stages of diabetes with hsCRP <1 mg/dL, the protective function was demonstrated with greater sRAGE levels. However, in further phase with 3 ≤ hsCRP < 10 mg/dL, the level of sRAGE was low, which is assumed to be associated with complications. Hence, sRAGE could be suggested as a complementary marker for hsCRP to evaluate diabetic men with central obesity.Keywords: sRAGE, hsCRP, diabetes, HbA1c, central obesity

Published: August 2017

Reciprocal interaction between oral ectodermal epithelial cells and mesenchymal stem cells (MSCs)-derived from the cranial neural crest starts the teeth development. The role of dental MSCs continues throughout life. The dental MSCs do not only play a role in tooth development but also in tooth homeostasis and repair. There are many kinds of dental MSCs, such as dental pulp stem cell (DPSC), stem cell from apical papilla (SCAP), stem cell from exfoliated deciduous teeth (SHED), periodontal ligament stem cell (PDLSC) and stem cell from dental follicle (DFSC). Aligned with the proposed criteria by the International Society for Cellular Therapy (ISCT), dental MSCs are adherent cells and like other MSCs, dental tissue MSCs are capable of giving rise to cell lineages such as osteo/odontogenic, adipogenic, and neurogenic. Various surface antigens of dental MSCs were reported, however, mostly typical antigens suggested by ISCT were fulfilled. Surface antigens from each dental MSCs (DPSC, SCAP, SHED, PDLSC and DFSC) are being described in the current report.Keywords: dental stem cells, mesenchymal stem cells, tissue regeneration, DPSC, SCAP, SHED, PDLSC, DFSC
Algunas consideraciones sobre política exterior y de defensa. El caso de Costa Rica
Authors: Murillo Zamora Carlos
Published: August 2017

Tradicionalmente las políticas exterior y de defensa se conciben y estudian como políticas públicas separadas y, generalmente, formuladas a partir de criterios y parámetros diferentes. Si bien se reconoce que se trata de dos políticas sui generis, porque se formulan a lo interno de los Estados, su implementación se produce en el ámbito externo, y por tanto responde a la forma de cómo los “decisores” (gestores con capacidad de decisión) conciben su rol como actores internacionales, y la percepción que tengan de las interacciones con otros Estados. Esto último evidencia que tienen cosas en común. Así, al profundizar en su análisis se comprueba que la política exterior y la política de defensa están entrelazadas, y responden al interés de sobrevivir y progresar que tiene el Estado. Por supuesto, tienen diferencias; una utiliza el recurso de la diplomacia y generalmente está basada en las relaciones en tiempos de paz, y la otra recurre a los medios militares y se orienta tanto a tiempos de paz como de guerra.

Authors: Clavijo Ardila Adolfo
Published: August 2017

El artículo analiza la situación de la seguridad nacional en torno a un interrogante central: ¿por qué no se le ha dado término a 50 años de conflicto interno en Colombia? Se tratan cuestiones como el diagnóstico incompleto con el que se ha pretendido darle término al conflicto; el manejo equivocado que siempre se le ha dado al enfrentamiento; la falta de organización del Estado para encarar el problema; y la carencia de políticas, estrategias y planes que conduzcan al desenlace de la confrontación. El documento discute algunos instrumentos que podrían encauzar estrategias más adecuadas a la situación actual.

Published: August 2017

Este artigo visa apresentar algumas reflexões a partir de uma pesquisa de doutorado realizada em três escolas, situadas em comunidades quilombolas do município de Bom Jesus da Lapa-BA, no Território de Identidade do Velho Chico. Buscamos analisar de que modo a educação escolar dialoga com as especificidades étnicoculturais das comunidades quilombolas. Para a coleta de dados, utilizamos entrevistas semiestruturadas com professores, gestores, coordenadora pedagógica, pais e lideranças quilombolas, grupos focais com os alunos, análises dos projetos político-pedagógicos das escolas, observações de eventos, registros fotográficos e anotações em diário de campo. Os resultados demonstram que as escolas tratam as especificidades étnico-culturais das comunidades quilombolas de maneira pontual, descontextualizada e superficial, em datas comemorativas, no componente curricular de história, gincanas e outros eventos. Todavia, constatamos algumas experiências pedagógicas significativas que vêm transgredindo os currículos escolares para dialogarcom o universo sociocultural dos alunos
História da educação e políticas educacionais entre saberes, conhecimentos e circulação internacional de discursos
Authors: Quadros Claudemir de
Published: August 2017

Este texto se caracteriza, sobretudo, como um exercício pelo qual se tentou perceber algumas relações entre duas áreas relevantes no âmbito da educação: história da educação e políticas educacionais. Para tanto, foram escolhidos quatro artigos publicados na revista História da Educação entre 2013 e 2015, selecionados a partir do critério de inserção internacional dos seus proponentes e porque potencializam perceber a perspectiva de circulação internacional de discursos no âmbito da formulação de políticas educacionais. Por esses textos procura-se demonstrar como aquilo que estamos acostumados a dizer é resultado de uma ampla rede de relações cuja autoria não é necessariamente nacional ou, em outros termos, que aquilo que conseguimos pensar acerca das políticas educacionais é circunscrito pelos discursos que circulam internacionalmente. Assim, o texto é atravessado por uma ideia geral: a circulação de discursos que, de um modo ou de outro, tem o potencial de estruturar, fixar, delimitar, circunscrever aquilo que pode ser considerado correto e verdadeiro. O esforço foi no sentido de perceber que ideias criadas, pensadas, fundamentadas pela pesquisa, pela ciência, propostas por intelectuais, lograram visibilidade e, além de contribuir para a estruturação de todo um campo de ação denominado políticas educacionais, têm o potencial de demonstrar que a formação dos sistemas escolares nacionais emergiu a partir de um amplo leque de relações internacionais.
Ativismo político e juventude:catracas na escola e na cidade para os Jovens mais jovens
Authors: Leite Miriam
Published: August 2017

Os movimentos de ocupação urbana ocorridos em diversas partes do mundo desde o início desta década foram, com frequência, associados à juventude. No entanto, o termo juventude é reconhecidamente pouco preciso quanto à idade que refere: estariam aqueles que frequentam os anos finais do ensino fundamental incluídos nesse reconhecimento de agência política? No contexto da greve docente da rede pública municipal de ensino do Rio de Janeiro, em 2013, realizamos entrevistas com professoras que participaram desse movimento, considerando que suas narrativas poderiam trazer notícias desse reconhecimento (ou não reconhecimento). Em diálogo com teorizações de Jacques Derrida, Judith Butler e Leonor Arfuch, discutimos sobre os textos produzidos nesses encontros, a partir das noções de performatividade,iteração, interpelação e entrevista narrativa. Assinalamos, nessa leitura, além da já suposta potência da interpelação docente, a força da própria cidade no favorecimento ou obstaculização da agência política desses jovens mais jovens.
A Case Study of Meditation to Reduce Alcohol Use Disorder Symptomology in Veteran PTSD Comorbidity
Authors: Hicks Craig Cameron
Published: August 2017

Background: Post traumatic stress disorder (PTSD) and alcohol comorbidity is becoming a rising issue within the military veteran community highlighted by research indicating individuals diagnosed with PTSD are more likely to have a drinking problem [1]. The implementation of meditation as an alternative form of stress release was aimed at reducing PTSD symptomology and therefor reducing factors that lead to drinking.Methods: A single veteran was recruited to complete a two-week intervention. The participant completed a behavioural diary noting alcohol consumption and mood respectively. During the middle of the study, an interview was undertaken to determine reasons of alcohol consumption and potential reasons and motivations for the cessation of drinking.Results: A moderate correlation between using meditation as a tool to reduce alcohol consumption in veterans with PTSD however this was not significant. Conversely, meditation was able to reduce PTSD symptomology.Conclusions: These results indicate that an alternative to drinking can be implemented as a successful form of treatment. However, these findings are specific to this study and need to be amplified and reproduced to determine if it can be applied to the general population.

Published: August 2017

Background

There is a need for brief screening methods for psychiatric disorders in clinical practice. This study assesses the validity and accuracy of a brief self-report screening questionnaire, the Web Screening Questionnaire (WSQ), in detecting psychiatric disorders in a study group comprising the general population and psychiatric outpatients aged 18 years and older.

Objective

The aim of this study was to investigate whether the WSQ is an adequate test to screen for the presence of depressive and anxiety disorders in clinical practice.

Methods

Participants were 1292 adults (1117 subjects from the general population and 175 psychiatric outpatients), aged 18 to 65 years. The discriminant characteristics of the WSQ were examined in relation to the (“gold standard”) Mini-International Neuropsychiatric Interview-Plus (MINI-Plus) disorders, by means of sensitivity, specificity, area under the curve (AUC), and positive and negative predictive values (PPVs, NPVs).

Results

The specificity of the WSQ to individually detect depressive disorders, anxiety disorders, and alcohol abuse or dependence ranged from 0.89 to 0.97 for most disorders, with the exception of post-traumatic stress disorder (0.52) and specific phobia (0.73). The sensitivity values ranged from 0.67 to 1.00, with the exception of depressive disorder (0.56) and alcohol abuse or dependence (0.56). Given the low prevalence of separate disorders in the general population sample, NPVs were extremely high across disorders (≥0.97), whereas PPVs were of poor strength (range 0.02-0.33).

Conclusions

In this study group, the WSQ was a relatively good screening tool to identify individuals without a depressive or anxiety disorder, as it accurately identified those unlikely to suffer from these disorders (except for post-traumatic stress disorders and specific phobias). However, in case of a positive WSQ screening result, further diagnostic procedures are required.

Published: August 2017

One of the major benefits of the air transport services operating in bigger countries is the fact that they provide a vital social economic linkage. This study is an attempt to establish the determinants of the passenger air traffic in Indonesia. The main objective of the study is to determine the economic variables that affect the number of airline passengers using the econometrics model of projection with an emphasis on the use of panel data and to determine the economic variables that affect the number of airline passengers using the econometrics model of projection with an emphasis on the use of time series data. This research also predicts the upcoming number of air traffic passenger until 2030. Air transportation and the economic activity in a country are interdependent. This work first uses the data at the country level and then at the selected airport level for review. The methodology used in this study has adopted the study for both normal regression and panel data regression techniques. Once all these steps are performed, the final equation is taken up for the forecast of the passenger inflow data in the Indonesian airports. To forecast the same, the forecasted numbers of the GDP (Gross Domestic Product) and population (independent variables were chosen as a part of the literature review exercise) are used. The result of this study shows the GDP per capita have significant related to a number of passengers which the elasticity 2.23 (time-series data) and 1.889 for panel data. The exchange rate variable is unrelated to a number of passengers as shown in the value of elasticity. In addition, the total of population gives small value for the elasticity. Moreover, the number of passengers is also affected by the dummy variable (deregulation). With three scenarios: low, medium and high for GDP per capita, the percentage of growth for total number of air traffic passenger from the year 2015 to 2030 is 199.3%, 205.7%, and 320.9% respectively.

Minimizing the distribution time in supply chain networks is critical. By minimizing the total time of distribution in the network we can reduce the cost as well as decrease the product wastage for goods with fast approaching expiration date such as dairy products. In real-world the traveling time in supply chain network is not deterministic most of the time and uncertainties in the form of randomness are not avoidable. For this reason, for finding the optimal path of distributor vehicles in the distribution network that has the lowest travel time, a probabilistic dynamic optimization model has been used in this study and the results of a numerical example are discussed.

Published: August 2017

The study investigated determinants of marriage stability among married couples in North Central Nigeria. In order to carry out this study, four hypotheses were formulated. An instrument known as “Determinants of Marriage Stability Questionnair (DOMSQ)” was constructed by the researcher and used to collect information from the field. The instrument had content and facial validity and its reliability coefficient is 0.87. The investigator used eight research assistants to administer nine hundred and ninety copies of the questionnaire on the respondents in Kogi and Benue States. Nine hundred and eighty three copies were retrieved from the respondents indicating 99.3 percent return rate. The researcher collated the information got from the field work and the Z statistics was used to test the hypotheses at 0.05 level of significance. The findings showed that, there was no significant difference between male and female married couples in their identification of childlessness as determinant of marriage stability, there was no significant difference between married couples in the urban and rural areas in their identification of sexual satisfaction as determinant of marriage stability, there was no significant difference between old and young married couples in their identification of cultural background as determinant of marriage stability, there was no significant difference between married couples from Kogi and Benue States in their identification of communication as determinant of marriage stability. One of the recommendations is that couples who are faced with the problem of childlessness should seek medical assistance and also be positive about such outcome.
The Pedagogic Role of Children’s Literature Walter Benjamin’s Theory in Modern Education
Authors: Ph.D Anastasia Chournazidi
Published: August 2017

This article focuses on the theory of German philosopher and literature critic Walter Benjamin (1892-1940) on the role of children’s literature and the degree by which his aesthetical theory, as expressed in the early 20th century, may be applied in modern education. Particularly in preschool ages, children’s literature plays a defining role in children’s development, stimulating learning memory and providing the foundations for the child’s perception of the world around him/her. Children’s literature and illustrations of children’s books, introduce children in learning and writing. In his theory, Benjamin describes how literature, and in particular the magic perceived by children’s mentality in fairytale, can and should be an integral part of education that does not apply standardized pedagogic norms or psychological interpretations, but promotes the way in which the child observes the world, imagination and intuitive perception.

Published: August 2017

Outcome-Based Education (OBE) is now identified as essential to excellence in education. OBE can be described as the transparent application of a set of measurable criteria in setting a standard of proficiency. The students’ perception is the most crucial part as they are the medium of the system, as they are the ones who undergo the system thoroughly, and are the final product of the OBE system. Thus, their perception will directly show the effectiveness of the OBE system. This study focused on students’ perception on OBE system that had been applied in KPJ Healthcare University College (KPJUC) since 2014, in terms of students’ understanding and academic achievement. This is a mixed model study, which consisted of quantitative and qualitative study. A descriptive method of analysis was used, wherein the quantitative data were gathered using questionnaires and a survey interview was done as a qualitative supplementary data. The findings of this study discovered that the students have a positive perception toward the system.

Stable carbon and oxygen isotopes were determined in molar enamel from fossil Pliocene equids from Rancho El Ocote in the San Miguel Allende basin, Guanajuato, and from Santa María, Tecolotlán basin, Jalisco. At each locality, the source was one molar from an individual Dinohippus mexicanus and one molar from an individual Neohipparion eurystyle. Results indicated that the N. eurystyle individuals from both localities had been C3/C4 mixed feeders, and had lived in open-zone vegetation (δ13C: -3.1‰ to -1.3‰; δ18O: -4.9‰ to -6.4‰). On the other hand, the D. mexicanus from Rancho El Ocote had fed upon C4 plants and lived in open zones (δ13C: -1.3‰; δ18O: -4.9‰), whereas the D. mexicanus from Santa María was a C3/C4 mixed feeder with considerable consumption of C3 plants (δ13C: -7.7‰; δ18O: -6.4‰). These results could be contrast to suggestions from previous isotopic work that D. mexicanus in Mexico predominantly fed on C4 plants and further samples analyses are warranted. This study contributes to the understanding of the Pliocene equid taxa from central Mexico and emphasizes the presence of different diets, ranging from exclusive C4 to mixed C3/C4 plants.

Understanding Machines: A History of Canadian Mechanology
Authors: Thibault Ghislain , Hayward Mark
Published: August 2017

Background The paradigms of cybernetics and media theory developed in the postwar era in response to new developments in technology and science. At their margins, an intellectual movement called “mechanology,” or the science of machines, also attempted to apprehend such changes.

Analysis The article uses the archival material of two major figures of mechanology, Canadians John Hart and Jean Le Moyne, to examine the overlooked contribution of mechanology to postwar debates on technology and culture. It contrasts the theories, concepts, and epistemologies of mechanology with both cybernetics and media theory.

Conclusion and implications The article reveals some of the reasons behind mechanology’s inability to establish itself as new field, and shows how the concept of “the machine” lost ground in the postwar era.
