Authors: Cunha Rafael da Silva da , Ribeiro Cynara Teixeira , Soares Alessandra Miranda Mendes 
Published: March 2017

Resumo: O presente trabalho visa analisar as contribuições das disciplinas Psicologia da Educação e Prática de Ensino nos cursos de formação docente, especialmente no âmbito da Licenciatura em Computação e Informática (LCI), como também apresentar uma experiência de entrelaçamento destas duas disciplinas, realizada a partir de um projeto de extensão. A escolha da LCI justifica-se pelo fato de ser recente no Brasil e comprometer-se com a qualificação dos futuros professores para o uso das Tecnologias da Informação e Comunicação (TICs) no processo educativo. A experiência consistiu na aproximação de licenciandos com a realidade de escolas circunvizinhas à Universidade, com foco nas percepções de como as TICs estão articuladas à prática pedagógica para a posterior elaboração de oficinas pertinentes às demandas institucionais. Através desta experiência vislumbramos práticas pedagógicas capazes de contribuir para o saber-fazer e o aprender a ensinar a partir da ação-reflexão-ação. Palavras Chave: Formação Docente.

FORMAÇÃO PARA DOCÊNCIA NO ENSINO SUPERIOR: ESTUDOS SOBRE OS SABERES DOCENTES E OS PROGRAMAS DE MONITORIA
Authors: Souza Renato Oliveira de , Nery Vitor Sousa Cunha 
Published: March 2017

Resumo: O presente trabalho objetiva realizar um diagnóstico das produções cientifico-acadêmicas, partindo de eixos temáticos como: Saberes Docentes, Monitoria e Formação Docente para o Ensino Superior. Para tanto, sistematizou-se uma pesquisa bibliográfica das produções de teses e dissertações elaboradas no período de 2006 a 2014, de modo a estabelecer o Estado da Arte dessas produções e, assim realizar um balanço das mesmas de acordo com suas dimensões temporais, espaciais e teóricas. O corpo do trabalho se encontra divido em dois capítulos principais; O primeira aborda os aspectos conceituais e formativos dos Saberes Docentes conforme autores renomados na área, em seguida apresenta os aspectos conceituas, históricos e legais da Monitoria acadêmica, aludindo a trajetória e as transformações da monitoria ao longo da história brasileira; o segundo capítulo, apresenta um diagnóstico das produções de teses e dissertações elaboradas no Brasil, seguido da análise das mesmas. Os resultados evidenciaram que há poucas variantes metodológicas e referenciais nas produções, porém apresentam uma grande lacuna na produção trabalhos com a agregação dos referidos temas, pois somente um trabalho apresenta em sua pesquisa os três eixos temáticos. Diante de tudo, conclui-se que são poucas as produções com os temas supracitados, talvez por falta de interesse ou de informação, apontando para o não reconhecimento do potencial formativo docente das atividades de monitoria.

El fortalecimiento de la Fuerza Aérea Colombiana: una efectiva estrategia hacia la negociación
Authors: Melamed Janiel 
Published: March 2017

El presente artículo analiza cómo el fortalecimiento de la Fuerza Aérea colombiana a partir del inicio del nuevo milenio, permitió proporcionar importantes golpes militares a las Fuerzas Armadas Revolucionarias de Colombia (FARC-EP), llevando a esta organización si bien no a una derrota militar, si a un detrimento en sus capacidades operativas. Estas circunstancias de fortaleza en el terreno de batalla, permitieron que el Estado colombiano pudiera abordar un proceso de negociación y diálogo con esta debilitada organización subversiva, muy diferente a las desarrolladas en el pasado.
EOR Feasibility for Mexico's Mature Fields

Published: March 2017

Abstract
Within the Mexico energy reform, a static and dynamic characterization was made from two representative sectors from the mature fields bidded on the R1-L03 to evaluate the implementation potential for EOR.
Two reservoirs were studied using public and generic information in each of them:A naturally fractured carbonate reservoir, dual porosity (matrix/fracture), with tight porosity (6.3%) and permeability in the matrix and high permeability in the fracture. Clean Carbonate with low clay content, average depth: 3400 [m], fluid type is a gas and condensate with retrograde condensation (49.7 °API), with an underlining regional aquifer as the primary drive mechanism.The model is populated by 5 wells with a combined 2670 [m3/d] maximum production of oil and 3766140 [m3/d] of gas. This production declined to 16 [m3/d] of oil and 70800 [m3/d] of gas. The initial pressure of 376 [bar] being declined about 30% 279 [bar]. The model also contains a numerical aquifer.A shaly sandstone sequence reservoir highly laminated, containing high porosity (20%) and high permeability. Unconsolidated sandstone with average depth of 320 [m], the fluid is heavy oil of 20 °API, The reservoir is mainly discontinuous having poor or none vertically communication, arealy there are evidences of communication. The reservoir drive is mainly volumetric with no evidence of aquifer support.A sectorial model which contains 12 wells is used, this reservoir had produced for 46 years. The maximum production reached 825 [m3/d] of oil, currently the oil production is under 95 [m3/d].
In both models a history matching was made representative for pressure and production, then it was simulated a production forecast of 15 years with natural depletion and enhanced oil recovery implementation.
They were modeled through numerical simulation evaluating different enhanced oil recovery processes, both miscible injection (natural gas, N2, CO2, hydrocarbon gas injections) and thermal recovery (cyclic steam, continuous steam injection, SAGD and HASD); these methods were selected trough compatibility criteria for every case studied.
Miscible gas injection was simulated in the naturally fractured reservoir, the additional recovery factor achieved lies between 0.4 and 1.6%. With economic analysis this recovery factor might result in economic unviability, on the other hand according to simulation results a higher recovery factor and profitability could be reached with natural depletion adding drilling new wells and major workovers to the actual ones.
The thermal EOR methods were simulated in a sandstone reservoir containing heavy oil, in this reservoir a 0.7 to 4.2 % additional recovery factor was achieved and this indicates technical feasibility in the implementation of this kind of processes.
The Use of WalnutShell Filtration with Enhanced Media for Reduction and/or Elimination of Upstream Produced Water Treatment Equipment
Authors: Wiercinski Shane 
Published: March 2017

Abstract
Walnut shell media filtration has traditionally been used in upstream and downstream produced water treatment applications onshore. This has been largely driven by the footprint required for the flux rates traditionally applied to walnut shell filtration. At the traditional flux rates, walnut shell filters typically require a larger footprint atop a platform or FPSO than equipment such as hydrocyclones and gas flotation units. Recent developments including the incorporation of internalized backwash systems as well as increased processing capacity using reduced footprint has made media filtration using walnut shells more appealing to both onshore and offshore users and operators. In addition, there has been a trend to use tertiary treatment technologies downstream of secondary equipment such as flotation cells, due to the need to reduce hydrocarbon discharge to the environment.
One limitation in using walnut shell media is that walnut, as well as other nut shell media, are produced by, and are subject to, an agricultural season. Due to the fact that nut shell media are subject to uncontrollable environmental factors, crop yields can be sparse resulting in reduced availability. More recently, a synthetic alternative has been developed to replace nut shell media. The synthetic media is manufactured from materials that are not subject to yearly agricultural limitations. Through experimental and field testing, the following benefits have been observed in using this synthetic media:
Ability to handle greater than four to five times the amount of oil before requiring a backwash as compared to standard nut shell media Ability to maintain feed concentrations of greater than 500 mg/L while producing effluent well under 29 ppm Applicability to a wide range of oil API from 10-35+ and elevated temperatures greater than 90°C
This paper will highlight the performance data and results, backwash frequency, ability to remove and/or eliminate treatment equipment upstream of media filtration such as gas flotation and its combination with standard nut shell filtration. It will also highlight the potential reduction of treatment chemicals needed to enhance gas flotation and reduction or elimination of waste sludge into recoverable crude. It will also capture comparison of reduced footprint and weight as compared to full produced water treatment systems.

Published: March 2017

Abstract
This paper aims to discuss the behavior of different sucker rods steels in corrosive environments, the influence of manufacturing techniques and the development of a new Steel for Sucker Rod with enhanced properties for Corrosion-Fatigue.
Corrosion-fatigue is a major cause of premature failures in O&G industry and it is hard to predict its behavior. Besides the level of stresses, Corrosion Fatigue depends on many others factors, among which the most relevant are pressure, temperature, H2S and CO2 concentration, water, PH, chlorines and flow conditions.
Under harsh environment, steel performance is not only related to its mechanical properties. Parameters like alloying and residual elements, steel cleanliness, microstructure, toughness, among others play an important role.
Increased volumes of injection water/gas for mature fields, EOR and shale operations increase the risk of failures related to corrosion-fatigue mechanisms.
The performance of a steel material under the combined action of cycling loads and corrosive environments, depends on many factors, including the environment characteristics, the material properties, and the applied stresses. In corrosive environments, the fatigue life, both in terms of failure stresses or failure times, can be drastically reduced compared to the cycling stress in a non-corrosive environment.
A deep understanding of the behavior of standard steels and they failure mechanisms, allowed the development of a steel able to withstand harsh environments. Results of this research led to the development of new steel composition and processing routes, both for sucker rods and couplings, that notably increase the performance under corrosive environments.
Steel chemistry and manufacturing process were specially design to obtain a fine grain and ultraclean steel with increased hardenability and tempering resistance, and improved toughness. This features provides to the final product an outstanding Fatigue resistance in corrosive environment such us H2S and CO2.

Published: March 2017

Abstract
Certain heavy oils that foam under severe depressurization give rise to increased recovery factor and an increased rate of production under solution gas drive. Alongwith stabilizing foam, at lower volume ratios, these oils have the ability of stabilizing dispersion of gas bubbles. Chemistry of oil and its viscosity are the reasons for this. In comparison to conventional oils, response of foamy oils to drawdown of pressure is more favorable; primary recovery factor, rate of production, volume ratio of oil to gas that is recovered and the length of time that a given pressure gradient or rate of production can be maintained, all increase substantially. It is a complex phenomenon with intrinsic properties, thus it requires a robust understanding of each factor in this recovery process. In this study, the significance of factors that influence foamy oil recovery in horizontal wells is investigated and outlined.
A robust commercial optimization and uncertainty software is coupled with a full-physics commercial simulator that models the phenomenon with bubbly oil approach in order to investigate the significance of major parameters, on performance of horizontal wells in a foamy oil reservoir in the North Sea. Fluid properties of Maini et al. are employed. Foamy oil is modeled as small bubbles in oil along with small mobile droplets of gas in oil, larger trapped droplets of gas phase and flowing discontinuous gas foam where bubbles can affect viscosity and compressibility along with foam mobility reduction in relative permeability effects, which are region dependent is incorporated.
Sensitivity and optimization has been done on major reservoir parameters, such as, fluid and rock properties and well operational parameters. Tornado diagrams have been used to portray the significance of each parameter. It is observed that a robust approach on handling of uncertainties in reservoir are as important as management of well operational parameters in the scope of reservoir management.
Reasons for the favorable response of foamy oils in solution gas drive are not well understood and tentative explanations that have been put forward are controversial, where utilization of horizontal wells adds another degree of complexity. This study provides an in depth optimization and uncertainty analysis to outline the significance of each major parameter involved in production performance and ultimately the recovery efficiency in foamy oil reservoirs produced with horizontal wells.
Geochemical Modelling of Carbonated Low Salinity Water Injection CLSWI to Improve Wettability Modification and Oil Swelling in Carbonate Reservoir
Authors: Lee Ji Ho , Jeong Moon Sik , Lee Kun Sang 
Published: March 2017

Abstract
Conventional carbonated water injection (CWI) induces oil swelling and reduction of oil viscosity and density. The CO2 solubility in carbonated water is a key factor to determine these effects and is sensitive to pressure, temperature, and salinity. The CWI has another aspect of CO2 storage due to solubility trapping mechanism. Low saline water is a favorable condition to solubilize CO2 into brine due to salting-out phenomenon. As well, the low saline water injection (LSWI) has potential to enhance oil recovery originated from wettability modification in a carbonate reservoir. In terms of geochemical aspect, low saline brine introduces higher CO2 solubility and wettability modification effect. It has triggered the evalution of hybrid process, which integrates LSWI with CWI. The CO2 dissolution and wettability modification effects are highly related to geochemical reactions in brine/oil/rock system. This study has constructed the numerical modelling of carbonated low salinity water injection (CLSWI) coupled with geochemical reaction and evaluated the performance in terms of oil production and CO2 storage.
In core and pilot systems, the wettability modification effect of CLSWI contributes to 9% and 15% increased oil recovery over CSWI. In both systems, more CO2 has been captured up to 17% and 45% due to salting-out phenomenon, respectively. CLSWI enhancing oil swelling and oil viscosity reduction has also improved injectivity up to 31% over CSWI in pilot system. The results from this study has demonstrated that CLSWI is a promising water-based hybrid EOR.

Sandpack Filterability- Faster Way to Screen Polymers and Measure Resistance Factors for Laboratory and Field Applications for EOR
Authors: Rane J.. , Howard S.. , Fournier F. M. 
Published: March 2017

Abstract
Objective of this study is to introduce a novel derivative screening technique using a field sandpack based on modified Seright's filterability apparatus to deliver fast and effective results. For polymer manufacturers, it is often important to understand injectivity of several polymers for a particular EOR application. Space, time and labor constraints can make polymer screening by core flood testing quite cumbersome and expensive. This technique could be of help in such situations. For oil operator companies, it could be useful to screen and reduce the number of polymers to evaluate through third party tests. This technique also could be used at a field location to understand if there is blocking potential of polymer solution for different batches and estimate the resistance factor (RF). This new technique, sandpack filterability, could act as effective tool to screen various polymers for a particular EOR application using field sand instead of core flood techniques currently utilized.
Sandpacks can be prepared from field or generic sand. A chromatography column is used to prepare a sandpack, which is connected to a pressure tank. Different polymers are chosen for a particular field application. Polymer solution corresponding to throughput of 1000 cm3/cm2 of polymer is passed through the sandpack and sandpack resistance is calculated over throughput at a constant pressure of 20 psi. Polymers showing increase in sandpack resistance with increase in throughput could potentially block the formation.
For RF measurements- flow rates of brine and polymer solutions through sandpacks are measured at different pressures. Using Darcy's law, RF is the ratio of flow rate of brine to that of polymer at constant pressure. RF against shear rate (or flux) is plotted. This technique effectively measures RF that is in close agreement with the core flooding data. Case study of 5 Kemira polymers is shown for a particular field.
Although 5 polymers pass traditional tests with a filter ratio of less than 1.2 through 1.2 microns polycarbonate filter, sand pack filterability results differ. Based on mineralogy of field sand and pore throat size distribution, the flow of polymer through the porous media can change. Flow through the sandpack should demonstrate more realistic behavior of the polymer in the field. This technique narrowed down the polymer selections to 2 polymers based on filterability and sand pack filterability results.
Those 2 polymer were screened for RFs in sand packs and core floods at different shear rates for correlation. Differences and similarities between these two techniques (novel sand pack filterability and core flooding) are compared in this study to understand strengths and weaknesses of the novel test. This novel testing could help in many scenarios to understand injectivity of the polymer and help measuring RFs with minimal equipment, time and cost.
