Published: June 2017

Resumo: A energia eólica é cada vez mais utilizada em todo o mundo como uma importante contribuição para a energia renovável. Entretanto os países de interesse estão preocupados com seus respectivos impactos ambientais. Assim, com a finalidade de contribuir com a discussão sobre este tema, o presente estudo teve como objetivo analisar o uso da energia eólica como fonte renovável e limpa, e apresentar o seu respectivo potencial gerador, podendo ser ela uma alternativa energética e grande aliada no combate a emissão de gases do efeito estufa. Assim concluiu-se neste estudo que a energia eólica tem um futuro ainda mais promissor com a conscientização pública das suas vantagens como fonte renovável e progressiva competitividade econômica. Contudo mesmo apresentando, como toda tecnologia energética apresenta, algumas características ambientais desfavoráveis, conforme visto neste trabalho, o aproveitamento dos ventos para geração de energia elétrica deve ser encorajado e algumas destas características podem ser significativamente minimizadas e até mesmo eliminadas com planejamento adequado e inovações tecnológicas.

Resumo- Estudos sobre a biologia populacional das espécies são de grande importância, pois fornecem base para o acompanhamento da flutuação populacional. Dessa forma, o objetivo deste estudo foi analisar a estrutura populacional do ermitão Calcinus tibicen em Anchieta e Guarapari, litoral do Espírito Santo, com ênfase na distribuição de frequências dos indivíduos por grupo de interesse e a razão sexual. Em cada região, foram amostrados quatro pontos (P1, P2, P3 e P4), durante o período de outubro/2014 a setembro/2015. As coletas foram realizadas manualmente, com esforço de captura de um coletor, e com duração de 10 minutos. Os animais foram identificados, sexados e mensurados. A razão sexual foi calculada pelo teste X². Foram coletados 1029 indivíduos, e estes apresentaram distribuição unimodal, caracterizado por um equilíbrio dinâmico e uma estrutura estável. A razão sexual foi maior para as fêmeas, nas duas regiões amostradas. Os resultados do presente estudo sugerem que Anchieta e Guarapari, litoral do Espírito Santo, apresentam condições propícias para o desenvolvimento e estabelecimento de C. tibicen. Palavras-chave: estrutura populacional, crustáceos, distribuição unimodal.

Published: June 2017

Alcachofra é um vegetal utilizado na culinária e algumas de suas ações biológicas foram descritas, como ação antioxidante e anti-inflamatória, porém foi pouco relatada sua atividade sobre micro-organismos. Com isso, o objetivo do presente estudo foi verificar o efeito antimicrobiano do extrato de alcachofra sobre P. aeruginosa. Primeiramente, foi verificada a ação deste extrato sobre cultura planctônica, pelo método de microdiluição em caldo (50 a 0,09 mg/mL), em seguida, sobre biofilme formado por 48 h em poços de placas de microtitulação, com exposição de 5 min ao extrato de alcachofra (200 mg/mL). Solução salina 0,9% e clorexidina 0,12% foram utilizadas como controles. As reduções do biofilme foram verificadas pelo teste de MTT e analisadas estatisticamente por ANOVA e Tukey Test (p ≤ 0,05). Em culturas planctônicas foi verificado que as concentrações avaliadas não foram efetivas (CIM > 50 mg/mL), contudo, sobre o biofilme foi verificada redução significativa de 42 ± 16%. Desta forma, pode-se concluir que o extrato de alcachofra apresentou efeito antimicrobiano sobre biofilme de P. aeruginosa.

Background: Corticosteroids are extremely effective drugs and are used extensively in the management of asthma. Inhaled corticosteroids may offer some benefit in patients with mild to moderate obstruction in acute exacerbation and also offer the advantage of administration directly to the lungs. Hence this study was done to evaluate the efficacy of nebulized budesonide as compared to oral prednisolone in the management of moderate exacerbation of acute asthma.Methods: A total of 80 children attending pediatric emergency of SMGS Hospital Jammu aged 1 to 18 years with a moderate exacerbation of asthma despite three salbutamol nebulizations were enrolled and randomized into two groups. First group recieved nebulized budesonide (800 mcg) at hourly intervals for three doses followed by twice a day (n=37) while second group recieved oral prednisolone 2 mg/kg/day in two divided doses (n=43). Both groups continued to receive oxygen inhalation and nebulized salbutamol (0.15 mg/kg/dose) initially at hourly intervals for 3 doses followed by 6 hourly. The pattern of response as observed by the pulmonary scores in the two groups was compared.Results: The pulmonary scores were significantly improved at 1, 2 and 6 hours after starting treatment in the budesonide group as compared to prednisolone group (p < 0.01) although the difference was not significant after 12 hours. Oxygen saturation also showed a significant early improvement.Conclusions: This early demonstrable significant improvement in the clinical parameters of the inhaled budesonide group apparently suggests that inhaled budesonide may be efficacious in treating moderate exacerbations of asthma.

An ROP Predictive Model in Nile Delta Area Using Artificial Neural Networks
Authors: Amer Mustafa M. , DAHAB Abdel Sattar , El-Sayed Abdel-Alim Hashem 
Published: June 2017

Abstract
Bit performance is a key factor to improve drilling performance and reduce drilling costs; however, factors controlling bit performance are many and the interactions between these factors are very complicated.
This research provides a tool that represents this complex physical phenomenon using artificial neural networks (ANN) to predict the rate of penetration (ROP) to optimize bit selection. Lithology changes, drilling parameters data, and bit data were the inputs of our model.
Field datasets were collected from six different wells in the Nile Delta area represented by more than 12,000 records; these records were subjected to statistical analysis to exclude the data outliers and bad quality records. The cleansed datasets (more than 7,000 records) were normalized as a preprocessing step prior to building the ANN model.
Many exploratory models were developed prior to building the final model. These exploratory models indicated that a back-propagation feed-forward ANN is the proper ANN type that will produce acceptable representation of the physical process with reasonable predicted values of ROP.
The developed ANN model was trained, validated, and tested to predict ROP using the cleansed data set. The correlation coefficient was over 0.90 for the training data. For testing data, the correlation coefficient ranged from 0.88 to 0.90.
Statistical analysis of the model outputs comparing the actual measured values shows a low average absolute percent error, low standard deviation, low maximum error, and low root mean square error. When datasets from outside the selected research area were used for prediction, the model introduced an unsatisfactory result of ROP predictions with a correlation factor less than 0.5; which means that the model should be retrained using data records from the area of concern before using the model for predicting ROP. The newly developed model can be used only within the range of the training data used; therefore, care should be taken if other data beyond this limit is utilized.
Impaction and Wear-Resistant Carbon Elastic Seal for HTHP Downhole Valve Application
Authors: Zhao Lei , Xu Zhiyue , He Peter 
Published: June 2017

Abstract
In this work, an elastic carbon composite, a new category of high-pressure/high-temperature (HPHT) seal material, was developed and its successful application in downhole valves is discussed to demonstrate how it could address sealing challenges in HTHP and sour wells exploration.
As conventional oil and gas resources decline, exploration and production (E&P) activity increasingly involves operations in extreme HPHT conditions and corrosive sour environments (high in H2S and CO2), posing tremendous challenges on almost all aspects from drilling to completion and production. One of these challenges is developing reliable seals for various kinds of downhole valves, e.g., safety valves, chemical injection valves, pressure relief valves, etc., that must withstand HPHT and sour environments and must work under frequent impact and wear caused by operation or sands from downhole fluids. Under HT conditions (usually above 500° F), current valve seals made of plastic or rubber are no longer suitable, because the material loses its mechanical strength and becomes very soft. Therefore, these seal can easily extrude and fail under pressure. Metal-to-metal seals may perform better in HPHT conditions, but they have a very high failure rate due to low elasticity and high metallic hardness.
To address this issue, an elastic carbon composite, a new category of HPHT seal material, was developed. Material tests show that this novel carbon composite material has excellent thermal stability up to 1,000° F and strong resistance to impact and wear. This paper discusses the material property of this novel elastic carbon composite. The application of the material in a chemical injection valve is also be provided as an example to show how this new composite addresses downhole seal challenges for valve applications.
The novelty of this work is developing a new seal material that could enable downhole valve work at extreme HPHT conditions. Related knowledge and information of this work would benefit engineer in developing new technologies for various downhole valve tools.
Unconventional Pre-Workover Diagnosis and Decision Making using High Precision Temperature and Spectral Noise Logging: Case Study
Authors: Abduljabbar Ahmad M. , Guzman Julio C. , El Sheshtawy Mohamed 
Published: June 2017

Abstract
The current practices to monitor Tubing-Casing Annulus (TCA) integrity involves applying a sustained pressure with inhibited fluid in the annulus space. This is to allow for a positive indication of pipe integrity. In such cases where integrity is lost, it is challenging to diagnose or pinpoint the exact leak source. Because of the current limitations in the assessment procedures, inaccurate diagnostics can result, which can lead to expensive and time consuming operations and deferred production.
Well-A is a single string well drilled as a vertical oil producer. The well has undergone several workover operations and was recompleted as a single string observer many years ago. After being healthy for a long period, it was reported in recently that this well was suffering loss of TCA integrity. In addition, the tubing was reported to have an obstruction above the packer, and the master valve was in a partial stuck-open position. Since diagnosing downhole problems will allow for a safe, optimized and long lasting remedy job, it was decided to run High Precision Temperature (HPT) and Spectral Noise Logging (SNL), to assess the integrity of the TCA, and identify the source of the leak. The investigation was carried out rig-less, prior to moving the rig, to reduce time and optimize cost.
The results showed that the loss of TCA integrity was due to a casing leak, and confirmed the packer and seals integrity. This useful information eliminated the necessity of securing the reservoir below the packer, reducing costs and saving one week of rig time. In addition, proving that no communication existed between the reservoir and the TCA prevented sidetracking the well, which would have resulted in incurring a significant cost and about 1.5 weeks of rig time.
Surface Jet Pump Trial Test in Safaniya Field: Evaluation and Case Study
Authors: Mei Wenrong , Peeran Syed 
Published: June 2017

Abstract
Oil producers sometimes perform unexpectedly below expectations. Low performance could be caused by many reasons. Formation damage inside the near wellbore region, liquid load-up, and high back pressure imposed by the production system are just some listed among the many reasons. To revive or to boost the production of under-performing wells, especially impacted by liquid load or by high back pressure, a surface jet pump provides a quick and economical way as it consumes no external energy such as electricity and contains no moving parts. The surface jet pump utilizes the pressurized fluids from a good producer to generate a suction power. The suction power created can be then used to reduce the back-pressure imposed on a weak producer sitting beside the good producer. The performance of this weak producer is therefore improved.
Presented and discussed in this paper is the brief description of working principle of a surface jet pump, factors affecting its performance, candidate well selection for the application, and a case study for one trial test of a surface jet pump in Safaniya field. Intensive well rates data along with wellhead pressure reduction over 60 days under different testing scenarios were collected, analyzed and presented to showcase the success of its application in one location of Safaniya field.
The trial test was successfully completed with positive results showing the feasibility of production boosting capacity achieved by a surface jet pump through both real production increase and reduction of back pressure imposed on the weak producers. To streamline the field implementation of the surface jet pump, and to meet the production increase expectation, some factors highlighted in the paper, which have a big impact on its outcome, must be carefully examined when choosing a candidate well for the application. Failure to consider the importance of those factors would result in no production gain at all.
Scale Resistant Production Tools

Abstract
A novel silicon and oxygen doped diamond like carbon coating was developed to reduce the build-up of scale from oilfield production tools such as sub-surface safety valves and gas-lift valves. The coating was deposited on 2" × 2" flat metallic coupons, and its performance was compared with those of commercial coatings conventionally used as anti-scale coating by the industry, such as fluoropolymer and Ni-P-fluoropolymer coating via custom scale growth experiments at 85°F and 150°F, micro-scratch testing for coating-substrate adhesion, and environmental compatibility in downhole brine and oil at temperatures up to 400°F.
The results showed that the doped-DLC coating had the best anti-scale property. Under identical test conditions, the weight of scale deposit on the doped-DLC coating was substantially (up to 90%) less than other coatings, likely due to its low surface energy and smooth surface roughness. The abrasion resistance (5 times higher) and environmental compatibility of the doped-DLC coating was also superior to the other coatings.
Field trial studies of the coating is currently underway on multiple coated sub-surface safety valves and gas lift valves. The coated valves were put in the same wells and completion configurations in which an operator was having to replace the safety valves every 5-6 months due to scale plugging, whereas it's been 8 months since the doped DLC coated valves were deployed and the coated valves are functioning properly. These results suggest that the coating is preventing or minimizing the scale build-up from the valves. Analysis of the valves, once they are retrieved from the wells, will be conducted to fully determine the benefits of the coating.
