AS CONSTRUÇÕES DAS CIDADES SEGUNDO SEUS PRINCÍPIOS ARTÍSTICOS A PARTIR DA PRAÇA EM CAMILO SITTE
Authors: Silva Júlio César Da 
Published: March 2018

Na obra A Construção das Cidades segundo seus Princípios Artísticos,de Camillo Sitte marcou suas teorias urbanísticas ao tratar da dimensão estética das cidades tal qual obra de arte, ampliando a preocupação para além do que é atender as necessidades funcionais. A crítica é bastante profícua ainda na atualidade, pois as novas construções ficaram simplesmente técnicas perdendo o efeito artístico que fazia bem ao espirito; e ainda, a questão de até que ponto na modernidade as construções passaram a ser vistas do ponto de vista artístico somente, deixando, assim, a funcionalidade, a humanidade, de lado. Destarte, o sucesso desta obra se deu principalmente por tratar sobre a construção das cidades sobre a visão do cidadão, que transita pelas ruas, pelas praças, nos mais variados percursos, enxergando-a como uma somatória de fragmentos, para assim ter a visão totalizante da cidade. É claro que o ponto de partida de Sitte é a praça, pois, ela liga as partes, faz com que as partes sejam sentidas quando o que passa encontra seu espaço livre.
O BELO E O ORNAMENTO: relações entre Vitruvio, Leon Battista Alberti e Guarino Guarini
Authors: Borges Carolina Da Rocha Lima 
Published: March 2018

O presente artigo discorre sobre as concepções dos arquitetos e teóricos italianos Vitruvio (Marcos Vitrúvio Polião – séc. I a.C.), Leon Battista Alberti (1404 — 1472) e Camilo Guarino Guarini (1624 -1683) a respeito da beleza e do ornamento na arquitetura. Vitruvio entende o ornamento como parte da arquitetura, Alberti separa ornamento de estrutura, sendo que o primeiro completa a arquitetura. Guarino Guarini propõe que os esquemas das linguagens clássicas não são imutáveis e podem ser corrigidos em função das necessidades modernas.
LEI NATURAL, CAUSALIDADE E DESTINO: alguns apontamentos sobre a relação entre as moiras e os deuses em Ésquilo
Authors: Leão Eryc De Oliveira 
Published: March 2018

O que se lê nas próximas páginas é o início de um estudo dos conceitos de Natureza, Destino e Causalidade Natural, de importância central à física grega e a toda a história da ciência posterior, por meio de estudo filológico e lexicológico de figuras mitológicas olímpicas – responsáveis, cada uma, por uma parte da natureza – e das Moiras, responsáveis pela partilha inicial das responsabilidades, pela divisão dos domínios naturais entre os deuses e, de modo geral, pelo estabelecimento daquilo que poderia ser chamado de lei natural da qual os olímpicos não poderiam escapar. Esse trabalho segue de perto a tese de historiadores como Cornford e Dodds, segundo a qual as categorias do pensamento filosófico e científico sobre a natureza carregam traços e sobrevivências vigorosas de categorias do pensamento religioso primitivo, e são melhor entendidas nesse contexto geral. Ésquilo foi escolhido dentre os tragediógrafos clássicos por ser considerado um espelho mais fiel da tradição homérica e religiosa de seu período e melhor porta de entrada para o assunto.

Published: March 2018

Au cours d’une enquête menée dans 88 fermes de deux provinces du nord-est de l’Algérie – Oum El Bouaghi et Skikda –, 89 cas cliniques de piroplasmoses, soit un taux d’infection de 11,6 % des bovins examinés, ont été enregistrés entre mai et septembre 2011 dans 86,4 % des fermes visitées. Trois espèces de piroplasmes ont été identifiées dans les étalements sanguins colorés au Giemsa : Theileria annulata (chez 94,0 % des bovins malades), Babesia bovis (33,7 %) et Babesia bigemina (3,4 %), avec 31 % de co-infections. Il n’y avait pas de différence significative de prévalence entre les deux provinces ni entre les races bovines. La theilériose tropicale a provoqué une baisse significative de la production laitière, estimée à 319 litres par vache infectée pendant les deux mois suivant la maladie. Sept espèces de tiques ont été collectées dans les fermes pendant l’étude. Le pic d’infestation a été observé en juillet pour Hyalomma scupense (syn. H. detritum), H. lusitanicum, H. anatolicum, Rhipicephalus bursa et R. turanicus, et en août pour H. marginatum et H. excavatum. Une corrélation positive a été observée entre les cas cliniques de theilériose tropicale bovine et la charge parasitaire en H. scupense, d’une part, et entre les cas cliniques de babésioses et la charge parasitaire en R. bursa, d’autre part.

L’alimentation des cailles (Coturnix coturnix japonica) dans les fermes ivoiriennes est basée principalement sur les aliments commerciaux de poules pondeuses. Cependant, cette pratique pourrait nuire à la qualité nutritionnelle des œufs. L’objectif de cette étude était de déterminer l’impact de cet aliment (régime témoin) ou de sa supplémentation avec 5 % de graines d’euphorbe (Euphorbia heterophylla) (régime R5) sur le profil en acides gras des jaunes d’œufs de 30 cailles de 172 ± 2 g durant 15 jours. Les résultats ont montré que le régime R5 ne modifiait pas les teneurs en acides gras saturés, en acides gras mono-insaturés et en acides gras polyinsaturés oméga-6 (AGPI n-6) (p > 0,05). Cependant, il a induit une amélioration de la teneur en acides gras polyinsaturés oméga-3 (AGPI n-3) (p < 0,05) qui était cinq fois plus élevée que celle du régime témoin. Les proportions des acides gras C18:3 n-3, C20:5 n-3 et C22:6 n-3 des jaunes d’œufs issus de R5 ont été multipliées respectivement par 17, 11 et 3. Par ailleurs, le rapport AGPI n-6 / AGPI n-3 était inférieur à 4. Ainsi, l’incorporation de 5 % de graines d’euphorbe dans l’aliment commercial de poules pondeuses a permis d’améliorer la qualité nutritionnelle des œufs de cailles.

SummaryIn oil and gas drilling, cuttings-transport-related problems are a major contributor to well downtime and costs. As a result, solutions to these problems have been extensively researched over the years, both experimentally and through simulation. Numerous review articles exist, summarizing not only the research history but also the qualitative effect of individual case parameters such as pump-flow rate, pipe rotation, and rate of penetration (ROP) on cuttings transport. However, comparing different studies is challenging because there is no common reference defined in the form of a typical and representative set of case parameters.To develop relevant and accurate cutting-transport models, it is critical that both experiments and models are targeting flow cases relevant for respective drilling operations. Development of a clear understanding of the industrial-parameter space, as well as establishing benchmarks, will help achieve a more-concerted effort in development of models and corresponding laboratory experiments.Other industries have established research benchmarks, such as the “NREL offshore 5-MW baseline wind turbine” (Jonkman et al. 2009) in wind-power research, providing a standardized set of case parameters and profiles, readily available for use to researchers worldwide, and resulting in straightforward benchmarking and validation as well as faster establishment of projects.For application to the modeling of cuttings-transport phenomena, we propose a methodology for deriving a well-defined and standardized set of geometrical, operational, and environmental case parameters describing various operating points of drilling operations and procedures as well as simplified problems. The methodology is exemplified with an 8.5-in.-section drilling-ahead use case with aggregated wellbore data from the Norwegian Petroleum Directorate (NPD). The relevance and application of the derived parameters are briefly discussed in light of modeling, both experimentally and through simulations. Applying this methodology before any cuttings-transport study may enable a better definition of industry-relevant case parameters.In Part 2, we will apply and discuss the derived parameter sets in the context of nondimensional numbers for assessment of scalability.
Oil Bank Build Up: An Experimental Approach
Authors: Saadi Faisal Al , Wolf Karl-Heinz , Kruijsdijk Cor Van 
Published: March 2018

Abstract
In chemical Enhanced Oil Recovery surfactants, solvents or other water based additives are used to mobilize micro bubble size trapped oil. Under favorable physical, chemical and spatial conditions the mobilized oil collects in an oil bank that will be displaced to the producer. Our understanding of when, and under which conditions an oil bank is formed, is very limited. This is relevant when core flow experiments are interpreted and upscaled from centimeter scale to field scale in various steps.
We built two experimental high precision setups for different volume scales to obtain reliable and accurate results. The first one is a Microfluidic setup, which visualizes and characterizes the dynamic of fluid flow at micrometer/pore scale. The second one is a high-end core flow setup which is used to study the dynamics of a mobilization process at meter/Darcy scale. These high-end development set-ups provide us with robust, accurate and repeatable experimental data for oil mobilization from micrometer/pore scale to one meter scale samples.
We experimentally demonstrated the process of oil bank build up at two different pore framework scales. These experimental results provided a high degree of data integrity. In addition, results give direct evidence for the mechanism of oil bank build up and upscaling procedure. We ensured the repeatability, reproducibility and integrity of the experimental data. We visualized and explored semi-quantitatively the entire process from mobilizing residual oil to dispersed flow to oil bank formation using a micro-fluidic device and core flow tests using cores of different lengths (7 – 100 cm)

Abstract
Thermal field development often requires trials or pilots to unlock additional oil recovery. "A" East (ALE) is a thermal EOR oil development project located on the Eastern Flank of the South Oman Salt Basin. An initial/ongoing development phase in the upper part of the reservoir primarily consists of Cyclic Steam Stimulation (CSS) followed by steam drive. Aiming to increase the field's total ultimate recovery, the next development phase was conceived to target the more viscous oil (up to 200,000 cP) in deeper zones, deemed too challenging in the first phase.
Many concepts were evaluated, however "Cross Top Down Steam Drive" (X-TDSD) was ranked as the most favorable option to address the development uncertainties. Similar to the Steam Assisted Gravity Drainage (SAGD), the injection wells will be positioned above the production wells. However unlike SAGD, the injectors will be placed perpendicular (cross) to the producers. Additionally, the XTDSD will assess the approach of utilizing a combination of steam flooding at the top, using vertical wells, and a gravity drainage process at the bottom using horizontal wells.
The X-TDSD trial scope includes the drilling and completion of two horizontal injectors, three horizontal producers, and three vertical observation wells. These will be accommodated within the existing infrastructure. The acceleration of the three observation wells reduced some of the main uncertainties prior to executing the horizontal wells. These included structural geology, stratigraphy, and grain size analysis for sand control requirements.
The success of the X-TDSD trial depends not only on reservoir properties, but also on the well and reservoir operating strategy. A clear plan for operating parameters and real-time surveillance were incorporated into the project development plan. Permanent production and injection monitoring are included, to facilitate systematic adjustment of the well parameters. This aims to optimize steam chamber development during the pilot's operating life. Flexibility was incorporated in the wells and facility design to accommodate the six planned modes of operation, as described later.
This paper will focus on the design details, which required integrated input from several disciplines.
Alkaline-Surfactant-Polymer Flooding: Where is the Enhanced Oil Exactly?

Published: March 2018

Abstract
With the advantages of high sweep efficiency and displacement efficiency, alkaline-surfactant-polymer (ASP) flooding can greatly improve the oil recovery by 20%. The microscopic displacement mechanisms have been reported in detail, however, the macroscopic 3D fluid flow characteristics still lack enough research. This paper is aimed to study the macroscopic flow dynamics in ASP and further clarify the distinctions of remaining oil saturation between waterflooding and chemical flooding.
The flow dynamics were examined at both laboratory and numerical scale. A sandpack physical model was designed to simulate the vertical heterogeneous reservoir. To analyze the pressure distribution during the ASP flooding, the model was equipped with 25 pressure transducers. Then we built the corresponding numerical model to simulate the ASP process. Basic experiments data were used for history match and chemical parameters. In the simulation, we investigated the base case (pure waterflooding) and seven chemical flooding scenarios (alkali, surfactant, polymer, alkali-surfactant, alkali-polymer, surfactant-polymer, alkali-surfactant-polymer flooding, respectively).
"Enhanced oil saturation (EOS)" is defined by subtracting each chemical flooding from waterflooding case. The distribution maps/profiles were generated for comparison in eight cases. Viewed from the x-y areal plane, in the cases added with polymer, the injected chemicals from main streamline were observed to gradually spread to the two sides apart to displace the remaining oil. Besides, chemicals were diverted into lower permeability at vertical section. Based on the saturation profile presented in each chemical flooding scenarios, we classified the enhanced oil area into 4 subzones: A-zone, S-zone, P-zone and ASP-zone. This division characterized both individual and synergistic effects in alkali, surfactant, and polymer. Sensitivity analysis was conducted to compare the influence of alkali, surfactant, and polymer with different concentrations on the area where oil was extracted. Results show that: (1) as the polymer concentration grew higher, all the sub-zones displayed increasing tendency, but the impact would diminish if the concentration exceeded 1500 mg/L; (2) a relatively rich surfactant-bearing solution helped expand P-zone, and the ASP-zone is also benefited; (3) an optimal alkali concentration is advised to be 1% ~1.5%.
We establish a comprehensive characterization of the fluid flow dynamics by performing physical experiments and numerical simulation. The novelty of the paper is the inspection on the location where extra oil is driven by the function of each component. The synergy in ASP is recognized by pressure and saturation distribution. The study provides a better understanding of macroscopic flow mechanisms in chemical flooding projects.
Hydraulic Concentric Tubular Pumping System for Lifting Oil in EOR Completions
Authors: Langbauer C. , Jax G. , Vita P. , Hofstätter H. 
Published: March 2018

Abstract
Conventional artificial lift systems are limited in their application by depth, borehole trajectory, and chemistry of the produced media. This paper presents a concentric tubular pumping system, combined with an efficient hydraulic pump to overcome the limitations of existing artificial lift systems and to assure a cost-effective production.
This pumping system consists of a specially designed pump&piston combination which is driven by a hydraulic pressure unit from the surface without any mechanical connection. The hydraulic pump itself can be circulated into and out of the borehole or can be run by slickline, resulting in fast and low-cost operations. The pump is designed to be run as a concentric tubular pumping system, which causes several advantages, especially in gas, thermal or chemical injection EOR installations. This new pump type is designed and manufactured in cooperation with the industry and tested at the Montanuniversität Leoben, Austria.
The performance and wear tests have demonstrated the saving potential in terms of energy efficiency as well as reduced CAPEX and OPEX. The unique design of this pump owns a very low number of moving parts, such no mechanical connection to the surface, and such providing minimal exposure to wear and corrosion. Tests have shown that the pump is very adaptable in terms of production rate, which just requires a change in surface hydraulic pressure. Based on experience the concentric tubular pumping system is the best selection for thermal and chemical EOR methods to enhance the lifetime of the completions. As a result of the natural phase separation of liquids and gases the presented pumping system has shown to be the ideal choice for the usage in all types of wells for gas injection EOR methods too.
This completely new pump type exceeds the performance of existing artificial lift systems, increases the mean time between failures and reduces the lifting costs essentially. These major issues are most important in times of low oil price, especially for tertiary recovery methods.
An Experimental Validation of a Smart Emulsion Flooding for Economic Chemical EOR
Authors: Wei Bing , Ning Jian , Shang Jing , Pu Wanfen 
Published: March 2018

Abstract
The depression of the current global oil market renders the majority of chemical EOR projects worldwide unprofitable, especially in china. Therefore, economic alternative technologies must be quickly developed. This paper evaluated the potential of a smart pre-formed emulsion flooding EOR in Block 9 based on the reaction between alkali and highly acidic crude oil. The static properties and dynamic displacement behaviors of the emulsion were thoroughly investigated. Particular emphasis was placed on the relationship between emulsion stability, droplet particle/pore radius matching, and EOR efficiency. The experimental results showed that the petroleum acids of the crude oil reacted with alkali (NaOH), and producing neutral emulsions (pH≈7.0). The emulsion rheology and morphology were strongly dependent on oil water ratio. From the economic point, the oil/water ratio of 0.5:9.5 was used to prepare two types of O/W emulsions (unstable and stable emulsions) with different particle sizes. The core flooding tests proved that a higher pressure during emulsion injection was generated than that of water injection due to Jiamin effect induced by the dispered oleic phase. As a consequence, the oil recovery factor was further improved by 6-17%. High matching factor and emulsion stability accounted for more significant EOR effect as we observed.
