Authors: Freitas Maria Cristiane 
Published: June 2017

Os meios de comunicação percorrem a linguagem verbo-visual para transmitir as informações que não são totalmente percebidas pelo leitor, mas são importantes para estabelecer sentidos aos enunciados. O objetivo deste artigo é investigar mecanismos e estratégias linguístico-discursivas e visuais da revista ÉPOCA EDIÇÃO ESPECIAL na respectiva capa de uma edição que tratou da morte de Osama Bin Laden, para compreender a arquitetônica linguística das capas de revista em suas relações dialógicas com o leitor implícito e o contexto histórico-social de que faz parte. As análises apontam com clareza que a revista, apesar de ser um veículo de informação que deveria ser imparcial, deu um tratamento ao assunto de forma a apoiar todas as decisões tomadas pelo governo americano, encaminhando o leitor a concordar com essas tomadas de decisões, não lhe restando alternativa. Este artigo está fundamentado na teoria dialógica da linguagem de Mikhail Bakhtin.

O objetivo foi avaliar a eficiência da estimação simultânea de índices morfométricos da copa de árvores de eucalipto em um plantio adensado empregando RNA. Foram estabelecidas três parcelas experimentais em uma plantação de eucalipto localizada no IFMG – campus de São João Evangelista. Realizou-se o inventário florestal aos 37 meses de idade. Calculou-se para cada árvore três índices morfométricos de copa. Foram treinadas 400 RNA para estimar simultaneamente os índices, sendo 200 Multilayer Perceptron (MLP) e 200 Radial Basis Function (RBF). Uma desvantagem observada foi a perda na precisão das estimativas de formal da copa, fato que pode ser atribuído a maior variabilidade dos valores observados (CV de 48 %) e à sua tendência linear constante. Conclui-se que a modelagem por RNA com arquiteturas MLP e RBF demonstraram adequabilidade e precisão para estimar os índices morfométricos proporção da copa e índice de abrangência, respectivamente.

Published: June 2017

<p>Criado pela Lei n° 10.861, de 14 de abril de 2004, o Sistema Nacional de Avaliação da Educação Superior (Sinaes) é formado por três componentes principais: a avaliação das instituições, dos cursos e do desempenho dos estudantes. A avaliação dos cursos é realizada por especialistas que fazem parte do banco de avaliadores do Inep. Por meio do preenchimento do instrumento de avaliação e de visita in loco, esse processo de avaliação conduz a um resultado, que varia de 1 a 5, denominado de Conceito do Curso (CC). O desempenho dos estudantes é verificado por meio do Exame Nacional de Desempenho dos Estudantes (ENADE), que dá origem a um conceito, também variando de 1 a 5, denominado de Conceito Preliminar de Curso (CPC). Como os dois conceitos referem-se ao curso, indaga-se se os resultados obtidos para um mesmo curso são ou não coerentes. Com base nos dados obtidos no PORTAL E-MEC (http://emec.mec.gov.br), uma comparação entre esses conceitos foi feita para os cursos de Engenharia Civil, Mecânica e de Produção. Este artigo apresenta os resultados obtidos e as principais conclusões que podem ser tiradas dessa comparação. Aparentemente, pela grande diferença entre os dois conceitos para um mesmo curso, parece haver uma necessidade urgente de se revisar as metodologias de atribuição dos valores do CPC e do CC.</p>

A Methodology for Screening Surfactants for Foam Enhanced Oil Recovery in an Oil-Wet Reservoir
Authors: Boeije C. S. , Vad Bennetzen M.. , Rossen W. R. 
Published: June 2017

Summary
A surfactant-screening methodology for foam enhanced oil recovery (EOR) is proposed that comprises both bulk-foam tests and foam flooding in model porous media. The initial foam screening (bulk-foam stability in test tubes) is aimed at quickly providing a qualitative indication of a surfactant's foaming potential as well as salinity and oil tolerance at reservoir temperature. Surfactant formulations passing these tests are tested further in a series of foam-flooding experiments in model porous media (bead packs) under reservoir conditions (100-bar backpressure, at 55°C) at 95% gas fraction, with and without crude oil (32°API) present. The mobility-reduction factor (MRF) (i.e., ratio of pressure drop across the pack with foam compared with that for water) is a direct measure of foam strength in porous media. To investigate the effect of wettability, tests are performed in both strongly water-wet (glass beads) and oil-wet (polypropylene beads) porous media.
The bulk-foam tests screened out most of the considered surfactants. Out of 31 surfactants tested, 26 precipitated in the highest-salinity brine (200,000 ppm). Also, the presence of crude oil resulted in foam collapse for most surfactants in the bulk tests. Surfactants that retained some foam stability in the presence of oil were carried forward to the porous-media tests. In our study, qualitative foam stability inferred from the bulk-foam-stability tests correlated well with the MRF in the water-wet bead packs. We found large variations in MRF comparing different surfactants; some have MRFs on the order of 10 and others are as high as 1,000. For all investigated surfactants, the presence of crude oil reduced MRF, but for some mobility reduction was still significant. The bulk-foam tests showed similar results, with foam retaining some stability even in the presence of oil for the surfactants that were analyzed in both bulk form and in porous media. Oil-wetness was found to have a detrimental effect on foam strength: Values of MRF were approximately one order of magnitude lower than those measured in the water-wet porous media. However, the decrease in MRF was not the same for all surfactants. The best-performing surfactant in the oil-wet pack was not the same as the best performer in the water-wet pack, proving the value of these additional tests.
The goal of the protocol is to obtain a method for rapid testing the foaming performance and stability of a range of surfactants under conditions that are as realistic as possible. The most-promising surfactant(s) identified by use of this protocol are then selected to be evaluated further in long consolidated cores.
New Algorithm to Quantify Well Productivity of Wells in Solution Gas Drive Reservoirs with More Than One Permeability Circular Region
Authors: Sadeed Ahmed , Al-Nuaim Sami 
Published: June 2017

Abstract
Oil well Inflow Performance Relationship (IPR) defines the reservoir potential to deliver fluid from reservoir into the wellbore. The IPR curve plays an important role to ensure the feasibility of drilling wells at a lower scale and the field development at a larger scale. Most of the available existing IPR correlations were developed for homogenous reservoirs. In reality, the reservoir seldom shows homogenous behavior. Using incorrect IPR correlation for a particular reservoir may induce uncertainty in the estimated flow rate for a given drawdown. This may affect the process of decision making especially in large-scale field development projects. Even though many analytical IPR correlations are available in the literature, but they are either complex or require unknown input parameters. This study focuses on the effect of composite reservoirs (more than one permeability regions/rings) behavior on IPR for solution-gas drive oil reservoirs. The main objective of this study is to develop a new empirical IPR correlation for composite reservoirs. Many investigators have developed correlations for a solutions gas drive reservoir for specific well/reservoir types such as dual permeability, multilateral, etc. where they fit well for a specific reservoir behavior and might be unrealistic for different reservoir types. The inflow performance relationships for composite reservoir with more than one reservoir properties regions (rings) are not yet investigated. Hence, there is a need to develop such correlation. The accuracy of the new IPR model is also quantified showing acceptable error as compared to other existing correlations. The new generated empirical IPR equation can be used to predict the performance of vertical wells in a solution gas drive composite reservoir with more than one heterogeneous regions (rings). This simple IPR correlation would provide petroleum engineers a simple and accurate tool for predicting the well inflow performance of composite reservoirs.
Investigating the Compatibility of Enzyme with Chelating Agents for Calcium Carbonate-Filter Cake Removal

Published: June 2017

Abstract
Removal of water-based filter cake that formed either during drilling or hydraulic fracture operations is a difficult task. Chelating agents were introduced in the oil industry to solve the common problems associated with the conventional acids (hydrochloric acid, an organic acid, or a mixture of these acids), such as rapid and uncontrolled reaction rate and corrosion to well tubulars, especially in horizontal and deep wells.
The objectives of this study are to (1) assess the reaction of starch with different chelating agents (GLDA, EDTA, DTPA) at different conditions of pH and temperature, (2) evaluate the compatibility of chelating agents with HTA enzyme (a-amylase enzymes), (3) assess the reaction of enzyme with starch and xanthan gum, and (4) design the best scenario for calcium carbonate filter cake removal.
The obtained results showed that EDTA (20 Wt%, pH 7, and 12), DTPA (20 Wt%, pH 7, and 12), and GLDA (20 wt%, pH = 4, 7, and 12) were not able to break the starch after hot rolling for different time period (12 hrs) at 200°F. These chelating agents were incompatible with α-amylase enzyme (HTA enzyme), which was able to completely break the starch in 6 hrs at 200°F. The best scenario to remove the calcium carbonate filter cake is to soak the filter cake with use α-amylase enzyme for 6 hrs and after that soak the filter cake with GLDA (20 Wt%, pH 4) for 16 hrs.
Low Salinity Water Flooding Possible Mechanisms and the impact of Injected Sulphate variation on Oil Recovery in Carbonate Reservoirs: Compositional Modelling Approach
Authors: AlSada Abdullah , Mackay Eric 
Published: June 2017

Abstract
Carbonate reservoirs store more than 50% of the earth hydrocarbon reserves with mostly mixed wettability. Water injection in these reservoirs likely results in low recovery due to uneven water movement.
In the past years, it has been noticed that Low Salinity Water Flooding (LSWF) regularly led to incremental recovery. Some of the possible Enhanced Oil Recovery LSWF mechanisms on the relation of the injected fluid composition and orginal reservoir fluids.In this study the effects of altering the concentration of the injected Sulphate ions on pH, CO2, calcite dissolution and its impact on oil recovery in carbonates are investigated.
Ca2+, Mg2+ and SO-4 2are determining ions to the carbonate surface which impact the surface charge of the rock (Zhang, 2006). The adsorption of the determining ions having conflicting charges Ca2+ and SO4 -2 on the carbonate rock surface is dependent on the relative concentration and equilibrium. An increase in pH causes a reaction with the acidic components of the oil which improves reservoir in-situ surfactants.
This study describes LSWF five spots simulation model with 4 producers and one injector. A 3D homogeneous reservoir was built using CMG simulators specifically the compositional simulator GEM. The basic data used to build the model like PVT data, crude composition, injected and connate water geochemical compositions were collected from several case studies conducted in a carbonate reservoir.
From the simulation results, pH was found to increase during the interaction between low salinity brine and reservoir rocks. The results show that dissolution of carbonate minerals can occur and this will alter the composition of the injected low salinity brine, the concentration of divalent ions on rock surface and hence the potential of low salinity to improve recovery. Calcite dissolution and indirectly Anhydrite Precipitation is being accelerated and controlled by the CO2 within the residual oil.
The study indicates strong bond between pH and CO2 and their effect on oil recovery while preforming LSWF. Enhancements on the injected water composition on a LSWF project based on the recommended chemical reaction controlling factors will enhance the understating of the driving mechanism of the LSWF and improve the oil recovery.
Advances in Transient Modeling: Conducting High Resolution Transient Modeling on Full-Field Coarse Simulation Models

Published: June 2017

Abstract
In this paper, we investigate the cause of the time-shift that occurs between the derivatives of the observed and simulated pressure transient data and present a methodology to perform full-field transient modeling without the need for single well fine grid sector models.
Pressure transient modeling is the process of simulating an observed well test sequence with the goal of comparing the derivative of field measured pressure transient to the derivative of numerically simulated pressure transient. Beginning from first principles, we investigated and showed in the current paper that simulation grid-block size introduces an undesireable shift in the derivative of simulated data which disappears as we approach fine grid simulation. We have termed this shift as grid-block storage phenomenon. As a result of this undesireable shift that occurs when coarse gid blocks are used, transient modeling is currently done using local grid refinement on sector models. The limitations of the current practice include; (i) large simulation run times due to use of fine grid simulation (ii) error related to boundary conditions when using sector models.
In this paper, we develop the equations governing pressure buildup behavior during grid-block storage dominated period as a function of simulation grid-size and simulation grid permeability. The insight from the derived equations reveals that the infinite acting radial flow stabilization (IARF) of the derivative of simulated pressure transient is always the same regardless of simulation grid-size. However, the onset of this stabilization is delayed as simulation grid-size increases and as simulation grid permeability decreases. Based on this insight, we then present the basis for an approach to history match the derivative of observed pressure transient without using local grid refinement on sector models. This approach is based on the use of derivative time-shift. Instead of using a fine grid sector model, we simply use the coarse full-field model to simulate pressure transient until the onset of IARF stabilization. We then shift the derivative of observed pressure transient right-wards to overlay corresponding features of the derivative of simulated data in a manner similar to type-curve matching.
This new approach called Time-Shift Methodology (TSM), presents a practical and efficient way of performing transient modeling on a full-field multi-well model without resorting to the time consuming conventional approach of using several single-well fine grid sector models.
