A cadaveric study on anatomical variations of kidney and ureter in India
Authors: Choudhary Umesh , Kumar Saroj , Jee Kanhaiya , Singh Anand , Bharti Priyanka
Published: May 2017

Background: The kidneys are a pair of bean - shaped organ located in the back of the abdomen between the 12th thoracic and 3rd lumbar vertebrae. Each kidney is about 4 or 5 inches long - about the size of a fist. The objective of this study was to study the major anatomical variations of kidney and urinary tract.Methods: The study was conducted during routine dissections of 32 cadavers over a period of 5 years. All specimens included in the study was adult cadavers of which 20 were males and 12 were females.Results: Out of 32 cadavers, 1 cadaver showed bilateral and 2 showed unilateral (2 L) lobulated kidney, 2 cadavers showed unilateral (1 L,1 R) and 1 showed bilateral accessory renal artery. 2 cadavers showed unilateral (1 L,1 R) incomplete double ureter.Conclusions: 12.5% of the cadavers showed anatomical variations in kidney and 6.25% showed bifid ureter. The knowledge of anatomical variations of kidney and ureter is of great importance for surgical, radiological and academic perspective. Hence, the early detection may be helpful in better management and increased survival rates.
Potentials and limitations for the use of accessibility measures for national transport policy goals in freight transport and logistics: evidence from Västra Götaland County, Sweden
Authors: Larsson Anders , Olsson Jerry
Published: May 2017

In Swedish national transport policy is freight transport regarded as a major facilitator for economic development on all geographical levels. At the same time it is noted that methods and data on business location and transportation is not adequate in order to follow-up transport policy objectives. This paper reports on a pilot study on the potential to develop accessibility measures to support and follow up policy objectives in Swedish context. The concept of accessibility and its practical use in concrete measures is discussed and problematized. A number of practical examples from Region Västra Götaland are used as illustrations. In terms of results the study identifies a number of potentials and limitations of using accessibility measures for freight transport issues. The usefulness is mainly driven by the integration capability of transport and land-use. This opens up for more complex questions and measures and thus supports the integration between planning specialisations. Limitations are to a large extent related to data availability and quality and to the degree of which models are possible to communicate to non-experts. The concluding discussion highlights how the policy and governance context is key in understanding how to best utilise the potential strengths of the accessibility concept and measures.

Treatment of Localized Aggressive Periodontitis With Guided Tissue Regeneration Technique and Enamel Matrix Derivative
Authors: Momen‐Heravi Fatemeh , Kang Philip
Published: May 2017

Introduction: Aggressive periodontitis (AgP) is a form of periodontitis characterized by rapid attachment loss in otherwise healthy individuals. Although different treatment options have been explored for management of the disease, control of disease progression and subsequent regeneration of the attachment apparatus are considered the ideal treatment objectives. Limited evidence is available with respect to the efficacy of different regenerative materials in the treatment of AgP.

Case Presentation: The present case report describes periodontal regeneration techniques and 6‐month outcomes in bilateral intrabony non‐contained defects around mandibular first molars in a 21‐year‐old patient diagnosed with localized AgP (LAgP). Periodontal lesions were treated with regenerative therapy with enamel matrix derivative (EMD) and allograft on the right side and allograft with bioabsorbable collagen membrane without EMD on the left side. Treatment yielded favorable clinical outcomes in terms of probing depth reduction, clinical attachment level gain, minimal gingival inflammation, and radiographic bone fill. Radiographic bone fill was observed after 6 months, suggesting possible periodontal regeneration.

Conclusion: Both regeneration techniques used in this clinical report (guided tissue regeneration involving allograft and bioabsorbable membrane versus EMD combined with allograft without a barrier membrane) resulted in favorable outcomes in the treatment of deep (≥7 mm) non‐contained intrabony defects in LAgP.

El Triángulo del Café, en Colombia, está conformado por los departamentos de Caldas, Quindío y Risaralda. Su diversidad geográfica, climática y de suelos permite identificar varios ecotopos cafeteros que se determinan por respuestas similares en cuanto a productividad. La caracterización de los ecotopos que se presenta en este artículo fue posible por la disponibilidad de información geográfica de libre acceso, producto de la Ley de Transparencia y del Derecho de Acceso a la Información Pública Nacional (Ley 1712 de 2014). La información utilizada para la caracterización está relacionada con geografía, hidrología, clima, geología, suelos y biomas. El análisis fue realizado empleando las herramientas de los sistemas de información geográfica. Los resultados permiten una mejor comprensión de los factores climáticos y geográficos que son determinantes de la productividad cafetera y, a su vez, brindan lineamientos para la ordenación y planificación del territorio.
Del poblamiento prehispánico al modelo territorial colonial en el municipio de Soacha, Cundinamarca: reflexión geohistórica de su configuración socioespacial
Authors: Rodríguez Silva Fabio Alejandro
Published: May 2017

A través de este artículo se presenta una síntesis espaciotemporal sobre la ocupación y transformación territorial de Soacha, Cundinamarca, en los periodos prehispánico y colonial. Para ello se recurre al método geohistórico, a conceptos de geografía urbana (situación, sitio, función y plano), a herramientas de cartografía temática e histórica, sistemas de información geográfica (SIG), fuentes secundarias y a otras disciplinas. En cuanto a la estructura del texto, se parte de la descripción de la situación geográfica de Soacha y se contextualiza el proceso de poblamiento de los cazadores recolectores y la cultura Herrera y Muisca, que denotan pautas de vida, producción, apropiación y organización territorial. Posteriormente, se enfatiza en la etapa colonial, en el cambio social y espaciotemporal dado en el contacto de nativos y europeos, analizando las formas de emplazamiento surgidas en la encomienda, el resguardo, la hacienda y el pueblo de indios, retomando, para este último sistema, las nociones de sitio, función y plano que permiten entender el origen morfológico de la ciudad de Soacha.
Topofobias e imaginarios del miedo sobre el espacio urbano de la localidad de Fontibón, Bogotá, Colombia

Published: May 2017

En la localidad de Fontibón, al occidente de Bogotá, D. C., las expresiones del delito poseen una lógica recurrente a partir de los lugares o espacios en que estos se presentan, situación que ha llevado a la configuración de imaginarios de miedo y topofobias en la población residente. Para analizar de forma comprensiva las relaciones de coincidencia o divergencia de estas dos perspectivas (la geografía del delito, junto con la geografía de la percepción), se asumen elementos metodológicos mixtos para caracterizar la existencia o no de factores explicativos desde una mirada territorial. Es así que, como resultado de esta reflexión, fue posible plantear algunas particularidades socioespaciales para comprender la territorialidad de la inseguridad urbana en la localidad.

Published: May 2017

O artigo identifica e delimita a existência de duas trajetórias tecnológicas em combustíveis líquidos sintéticos. O conceito de trajetória tecnológica é delimitado em função do ambiente de seleção e dos programas de pesquisa tecnológica, sendo aplicável ao nível das tecnologias. A primeira trajetória tecnológica tem por ambiente de seleção as limitações econômicas e militares observadas pelos países não-produtores de petróleo, o que culminou com os embargos da Segunda Guerra Mundial. Os programas de pesquisa buscavam desenvolver as tecnologias Fischer-Tropsch, hidrogenação em alta pressão e LTC (low temperature carbonization). O ambiente de seleção da segunda trajetória é delimitado pelo aumento das reservas de gás natural, pelas restrições ambientais e pela demanda por flexibilidade na cadeia de gás e energia. Os programas de pesquisa têm por objeto de estudo o processo de produção do gás de síntese necessário ao processo Fischer-Tropsch. A conversão direta do gás natural para combustíveis líquidos sintéticos apresenta-se como a promessa de uma inovação radical. Por fim, o artigo compara as duas trajetórias, identificando aspectos comuns e diferenças entre elas.
Struktura konstrukta čuječnosti: zavedanje doživljanja in sprejemanje doživljanja
Authors: Černetič Mihael
Published: May 2017

Čuječnost je v zadnjih dveh desetletjih v psihologiji in sorodnih vedah doživela močan razmah, vendar se je razmeroma malo raziskav osredotočilo na sestavo samega konstrukta. Namen prispevka je predstaviti, medsebojno primerjati ter kritično ovrednotiti različne vrste modelov konstrukta čuječnosti. Enodimenzionalni modeli opredeljujejo čuječnost kot zgolj posameznikovo zavedanje svojega trenutnega doživljanja. Dvodimenzionalni modeli čuječnosti vključujejo zavedanje trenutnega doživljanja ter sprejemanje tega doživljanja. V večdimenzionalnih modelih pa je čuječnost pojmovana kot konstrukt s tremi ali več faktorji. Problem enodimenzionalnih modelov je, da ne opredeljujejo kvalitete zavedanja, saj je lahko v določenih primerih posameznikovo samozavedanje tudi kontraproduktivno (npr. pretirano samokritično). Pri multidimenzionalnih modelih sta problematična precejšnje vsebinsko prekrivanje faktorjev ter vključitev pojavov, ki morda niso del same čuječnosti. Kot najustreznejši se tako izkažejo dvodimenzionalni modeli, ki najbolj jedrnato in hkrati dovolj kompleksno zajamejo vsebino konstrukta.
Severe trimming and enhanced competition of laterals as a tool to delay ripening in Tempranillo vineyards under semiarid conditions
Authors: Santesteban Luis Gonzaga , Miranda Carlos , Urrestarazu Jorge , Loidi Maite , Royo José Bernardo
Published: May 2017

Aim: An advance in grapevine phenological stages (including ripening) is occurring worldwide due to global warming and, in the hottest seasons, already results in a lack of synchrony between sugar and phenolic ripeness, leading to unbalanced wines. In order to cope with this fact, a general effort is being made by researchers and growers aiming at delaying ripening through cultural practices, particularly under warm growing conditions, where these effects are more deleterious. The aim of this work is to evaluate to which extent severe trimming and enhanced competition of laterals can delay ripening in Tempranillo vineyards under semiarid conditions.

Methods and results: The experiment took place during two consecutive seasons in Traibuenas (Navarra, Spain) in a cv. ‘Tempranillo’ vineyard trained to a vertical shoot positioned (VSP) spur-pruned bilateral cordon. Severe mechanical pruning was performed ca. 3 weeks after fruit-set in order to reduce leaf-to-fruit ratio, and in the trimmed plants, three irrigation doses were applied until harvest aiming at enhancing lateral growth, hypothesized to compete with ripening. All measurements were performed in six 10-vine replicates per treatment. Trimming significantly reduced leaf area and yield, resulting in higher water availability in trimmed plants. The whole ripening process was delayed by trimming: mid-veraison was delayed by about 5 days, and the delay in sugar accumulation and acid degradation was longer, differences being more marked in malic than in tartaric acid concentration. The use of increased irrigation levels compensated the losses in yield caused by trimming, enhanced laterals’ growth and implied an additional delay in ripening.

Conclusion: trimming and increased irrigation had an additive effect in terms of delaying ripening, and they can be used jointly when that delay is needed.

Significance and impact of the study: this study proves the potentiality of the joint use of trimming and increased irrigation to delay ripening, although it is necessary to analyze the implications the obtained delay has on other quality aspects. The lower anthocyanin and phenolic values observed in trimmed vines were not solely due to delayed ripening, as lower values were observed even when data were compared for a given total soluble solid content.
Multi-seasonal effects of warming and elevated CO2 on the physiology, growth and production of mature, field grown, Shiraz grapevines
Authors: Edwards Everard J. , Unwin Dale , Kilmister Rachel , Treeby Michael
Published: May 2017

Abstract: Industry concerns in Australia about the impacts of climate change have, to date, focused on the effects of warming, particularly shorter maturation periods. The effects of elevated CO2 concentration (eCO2) on C3 plant physiology have been extensively studied and suggest that eCO2 impacts on viticulture could affect grapevine shoot growth, fruit production and fruit composition. We previously used open top chambers (OTC) with an active heating system to study the effects of elevated air temperature (eTemp) on mature grapevines in the field. This system was augmented with the ability to elevate atmospheric CO2 and established in a mature Shiraz vineyard in a factorial combination of eTemp and eCO2. Three seasons of observations on the eTemp only treatment corroborated our previous study; all aspects of phenology were advanced, but leaf function was largely unaffected. In contrast, the effects of eCO2 on phenology were small in the first season, but increased over the subsequent two seasons. Interactive effects of the treatments on gas exchange were observed; photosynthesis rates were significantly higher in the eCO2+eTemp treatment, compared to eCO2 alone, suggesting that the likely future climate will have a larger impact on viticulture than might be predicted from experiments examining only one of these factors.
Combining ecophysiological models and genetic analysis: a promising way to dissect complex adaptive traits in grapevine

Designing genotypes with acceptable performance under warmer or drier environments is essential for sustainable crop production in view of climate change. However, this objective is not trivial for grapevine since traits targeted for genetic improvement are complex and result from many interactions and trade-off between various physiological and molecular processes that are controlled by many environmental conditions. Integrative tools can help to understand and unravel these Genotype × Environment interactions. Indeed, models integrating physiological processes and their genetic control have been shown to provide a relevant framework for analyzing genetic diversity of complex traits and enhancing progress in plant breeding for various environments. Here we provide an overview of the work conducted by the French LACCAVE research consortium on this topic. Modeling abiotic stress tolerance and fruit quality in grapevine is a challenging issue, but it will provide the first step to design and test in silico plants better adapted to future issues of viticulture.
A review of the current knowledge of red wine colour.
Authors: De Freitas Victor Armando Pereira , Fernandes Ana , Oliveira Joana , Teixeira Natércia , Mateus Nuno
Published: May 2017

Anthocyanins are the main compounds present in young red wines, being responsible for their intense red colour. These pigments are mainly located in grape skins and their extractability during winemaking depends on many factors, such as their concentration in vacuoles and interaction with the cell-wall polysaccharides, affecting their stability and concentration in the must. The red colour of anthocyanins at wine pH is explained by the stabilization of the flavylium cation form that displays a red colour; otherwise at this pH the hemiketal colourless is the dominant form, bleaching the wine. Besides the contribution of free anthocyanins, a phenomenon called copigmentation influences the colour of young red wines. Copigmentation can be defined as a series of stabilization mechanisms involving van der Walls interactions that occur naturally in red wines and that can explain this unanticipated colour behaviour. Copigmentation is also pointed as the first interaction between anthocyanins and other wine components leading after that to the formation of new coloured compounds during red wine ageing. Some of these pigments have already been identified and characterized but many are still undiscovered. The detection and structural characterization of new pigments, and the knowledge of their chemical formation pathways are crucial to better understand the evolution of the colour of red wine during ageing.
CFD Analysis on the Air-Side Thermal-Hydraulic Performance of Multi-Louvered Fin Heat Exchangers at Low Reynolds Numbers
Authors: Saleem Arslan , Kim Man-Hoe
Published: May 2017

The air side thermal hydraulic performance of multi-louvered aluminium fin heat exchangers is investigated. A detailed study was performed to analyse the thermal performance of air over a wide range of Reynolds number i.e. from 30 to 250. Air-side heat transfer coefficient and air pressure drop were calculated and validated over the mentioned band of Reynolds numbers. Critical Reynolds number was determined numerically and the variation in flow physics along with the thermal and hydraulic performance of microchannel heat exchanger associated with R_cri has been reported. Moreover, a parametric study of the multi-louvered aluminium fin heat exchangers was also performed for 36 heat exchanger configurations with the louver angles (19-31°), fin pitches (1.0, 1.2, 1.4 mm) and flow depths (16, 20, 24 mm); and the geometric configuration exhibiting the highest thermal performance was reported. The air-side heat transfer coefficient and pressure drop results for different geometrical configurations were presented in terms of Colburn j factor and Fanning friction factor f, as a function of Reynolds number based on louver pitch.
Flavonoid and Antioxidant Capacity of Propolis Prediction Usingnear Infrared Spectroscopy
Authors: Betances-Salcedo Eddy , Revilla Isabel , Vivar-Quintana Ana M. , González-Martín M. Inmaculada
Published: May 2017

Propolis is a bee product widely used as a dietary supplement and included in sweets or baby foods due to its well-known antioxidant and nutritional properties that are directly correlated with its phenolic composition. For this reason, this study analysed the total contents of flavones and flavonols, flavanones and dihydroflavonols, and the antioxidant capacity by using the methods of ABTS and linoleic acid/β-carotene in 99 samples of propolis from Spain and Chile. A rapid method was developed for quantifying these parameters in raw propolis using near infrared (NIR) spectroscopy with an optical fibre probe of remote reflectance applied directly to the ground up sample. The models developed allow the determination of the total of flavones and flavonols (0-183 mg rutin/ g propolis), of the total of flavanones and dihydroflavonols (9-109 mg pinocembrin/ g propolis extract), and the antioxidant capacity by the ABTS method (0-3212 nmolesTrolox/ mg of propolis) and of linoleic acid/β-carotene (22-86% inhibition). The NIR spectroscopy models were applied in external validation to different samples of the calibration group, which led to the conclusion that the methods developed provide significantly identical data to the initial chemical data of reference.
Environmental, Human Health and Socio-Economic Effects of Cement Powders: the Multicriteria Analysis as Decisional Methodology
Authors: Moretti Laura , Di Mascio Paola , Bellagamba Simona
Published: May 2017

The attention to sustainable-related issues has grown fast in recent decades. The experience gained with these themes reveals the importance of considering this topic in the construction industry, which represents an important sector in the world. This work consists on conducting a multicriteria analysis of four cement powders, with the objective of calculating and analysing the environmental, human health and socio-economic effects of their production processes. The economic, technical, environmental and safety performances of the examined powders result from official, both internal and public, documents prepared by the producers. The Analytic Hierarchy Process permitted to consider several indicators (i.e. environmental, human health related and socio-economic parameters) and to conduct comprehensive and unbiased analyses which gave the best, most sustainable cement powder. As assumed in this study, the contribution of each considered parameter to the overall sustainability has a different incidence, therefore the procedure could be used to support on-going sustainability efforts under different conditions. The results also prove that it is incorrect to consider only one parameter to select the ‘best’ cement powder, but several impact categories should be considered and analysed if there is an interest for pursuing different, often conflicting interests.
Kinetic of an In Situ Combustion Process in a Colombian Heavy Oil Using the Isoconversional Principle
Authors: Padilla J. , Muñoz S. F. , Trujillo M. L. , Rodríguez E.
Published: May 2017

An efficient way to increase oil production in heavy oil reservoirs is by the In Situ Combustion (ISC) process implementation. Part of the oil in place is oxidized, generating heat that increases mobility by reducing oil viscosity. The increase in oil production is associated with displacement mechanisms such as flue gas flooding, steam drive, viscosity reduction by oil swelling and temperature increase, among others. However, not all reservoirs are suitable for an ISC process. Therefore, prior to the implementation of an ISC project, the reservoir properties and reactive characteristics of oil should be evaluated.

The isoconversional principle is a technique to obtain information about oil oxidation characteristics, using the kinetic of the oil oxidation/combustion reactions. The isoconversional methods obtain the kinetic from different Ramped Temperature Oxidation (RTO) tests, usually three to five; this technique provides direct information of the effective activation energy. In addition, the technique can be used as a screening tool to identify good candidates to an ISC process and allow recognition of the number of dominant reactions to model the process in numerical simulators.

This paper presents the results obtained after applying the isoconversional principle in a Colombian heavy oil. Furthermore, a reaction scheme to model the process in a commercial numerical simulator is proposed. The reaction scheme was validated by matching the experimental results in a numerical thermal simulator.
Using Hybrid Propulsion Autonomous Marine Vehicles to Better Characterize Geomagnetic Fields Offshore
Authors: Poedjono B. H. , Pai S. , Maus S. , Paynter R.
Published: May 2017

We present a study conducted to develop and validate new capabilities for offshore geomagnetic surveying that employs the autonomous marine vehicle (AMV) to map the crustal magnetic field and monitor disturbance fields surrounding offshore drill sites. Knowledge of geomagnetic field direction and strength in the wellbore are essential parameters needed for directional drilling. To compute wellbore azimuth, the directional driller compares the magnetic field measurement provided by the measurement-while-drilling (MWD) tool with the geomagnetic field reference data to position the wellbore in real time while drilling. Correction for variations in the disturbance field is essential for accurate mapping of the crustal geomagnetic field. Unfortunately, land-based stations are not ideal for mapping the disturbance field in the offshore because of the distance of the station from the measurement site and the different electrical conductivity of the subsurface. To address the need for improved measurement of the disturbance field in offshore surveys, this study also investigated whether the new-generation, hybrid, wave- and electric-thruster powered AMV is suitable for use as a "base station" to monitor time variations of the geomagnetic disturbance field.

To conduct the study, we equipped two hybrid AMVs with towed marine magnetometers. Highly sensitive sensors established the minimum required separation between the AMV's electric thruster and the magnetic sensor payload. For validation as a base station, data collected by the vehicles from May 11 to May 14, 2015, was analyzed and compared with data obtained from the USGS Honolulu Geomagnetic Observatory (HON). To then evaluate the survey measurement system offshore, we compared data from a previous 2013 wave-powered AMV geomagnetic survey (Poedjono et al., 2015) with repeat data of the main, tie, and perimeter lines newly collected by the AMVs in this 2015 study.

Our results show that the AMV is ideally suited to carry out geomagnetic surveys in offshore remote locations, and a second AMV circulating at a fixed location provides a more accurate base station than a land-based station.

The hybrid AMV offers distinct advantages for geomagnetic data collection in offshore environments. The low cost compared to a seaborne or airborne vehicle allows AMVs to be deployed in tandem and collect data repeatedly over predefined areas, yielding accurate measurements to determine the disturbance and crustal magnetic fields. Use of the AMV solves the long-standing problem of how to accurately map the previously unknown geomagnetic reference field in offshore locations.

The objective of this paper is to introduce the Uruguayan Petroleum Fiscal Regime and to compare it against worldwide standards, with regards to the most commonly used statistic: Government Take, but also using other important statistics like Effective Royalty Rate, Savings Index, Lifting Entitlement and Progressivity. The ultimate goal is to measure the attractiveness of the Uruguayan oil and gas fiscal regime.

Based on the probabilistic model of a hypothetical oil and gas field development offshore, and Production Sharing Contracts cash flow diagrams, the Government Take, Effective Royalty Rate, Savings Index and Lifting Entitlement were calculated and averaged for all the Production Sharing Contracts in force in Uruguay. In addition, the Progressivity of the Uruguayan fiscal regime for oil and gas was tested, a crucial feature of the fiscal regime design considering the fluctuations in crude oil prices. The calculated mean values were compared with international petroleum contract averages obtained from literature.

Regardless of the fact that third party assessments attribute important volumes of hydrocarbon prospective resources to Uruguayan frontier basins (USGS 2011, 2012), there has never been a discovery in them yet and the geological risk is still significant. The main results of this work are that the terms of the contracts in force result in an average Government Take of approximately 70%, comparable with the Government Take of several hydrocarbons producing countries. Additionally, the calculated average Effective Royalty Rate was 9%, the Entitlement for the IOC averaged 52%, and the Savings Index resulted in 48%, all of them among worldwide standards. The Uruguayan fiscal system proved to be progressive, revealing state-of-the-art fiscal design. The overall conclusion is that the Uruguayan fiscal regime is fair (or could even be regarded as too harsh) considering the geological risk of the country's basins.

This work is useful for petroleum companies interested in assessing the hydrocarbon exploration and production potential of Uruguay, to easily compare the contract economy and its fiscal regime with other destinations. Furthermore, it might provide good insight to authorities to understand the attractiveness of the Uruguayan petroleum fiscal regime for design improvements.

Published: May 2017

As fields become mature and more laboratory data is available from specific geographical locations, it is possible to characterize, classify crude oils and develop or modify published correlations to better predict oil PVT properties. This paper shows the results from the attempt to classify and to provide calibrated correlations for the Ecuadorian crude oils. This study is divided in two sections, the first one makes a brief introduction to the main Ecuadorian oil fields, then the Oriente basin´s geology is described, geographical and statistical variation of crude oil properties is shown by reservoir and geological play. At the end of the first section, different criteria are applied to classify PVT samples showing that most data lie in the range of heavy oil. The second part uses the minimum square method to modify published correlations to provide relationships that helps the reader to better estimate oil properties in the absence laboratory data. Modified correlations as well as statistical results from the comparison of measured and predicted properties are listed at the end of this section.
Oil Mobilization by Viscoelastic Flow Instabilities Effects during Polymer EOR: A Pore-Scale Visualization Approach
Authors: Hincapie R. E. , Rock A. , Wegner J. , Ganzer L.
Published: May 2017

This paper investigates the additional oil recovery associated to viscoelastic flow instabilities encountered during polymer flooding. Single and two-phase polymer EOR experiments were conducted in micromodels that resemble porous media. To set a benchmark for non-viscoelastic flooding processes, Polystyrene Oxide (PEO) experiments are presented as well.

The experimental workflow consists of three main steps. First, saturation of the micromodel with a synthetic oil. Second, displacement of synthetic oil by an aqueous PEO solution. Third, displacement of the remaining oil by a viscoelastic polymer solution. For evaluation purposes, viscosity of the polymer and polystyrene oxide solution are approximately matched. Furthermore, tracer particles are attached to the aqueous phase to enable high quality streamline visualization. The streamline data is gathered using a highspeed camera mounted on an epifluorescence microscope.

In this study we demostrate that viscoelastic flow instabilities are highly caused and influenced by polymer properties. It is also shown flow instabilities dependence on pore space geometry and Darcy's velocity. We have observed a dependency of elastic turbulence on mechanical degradation, polymer concentration and solvent salinity. Furthermore, two-phase flood experiments in complex pore-scale geometries have confirmed that elastic flow inconsistency provides a mechanism capable of increasing oil phase mobilization by the viscoelastic aqueous phase. Due to high resolution particle tracing in the micromodels, the main causes of enhanced mobilization can be described as: (1) Moffatt vortices, (2) crossing streamlines, especially near grain surfaces and (3) steadily changing flow directions of streamlines. Thus, by adding viscoelastic additives to injection fluids and considering a sufficient shear rate, even a creeping flow is able to further enhance the displacement process in porous media by its elastic instabilities.

This work provides an adittional understanding of pore-scale polymer displacement processes, namely oil mobilization due to elastic turbulence/flow instabilities. Using the potential of state-of-the-art micromodels enables to conduct high quality streamline visualization which is the key to an improved polymer EOR screening. Thereby enables to understand which properties of viscoelastic solutions contribute to oil recovery. Moreover, this analysis can be used to modify subsequently the fluid characteristics in order to achieve an optimized process application.
Application of Numerical Simulation as an Integrated Methodology for Selecting the Best Candidates for Down Hole Heating. Huyapari Field, Orinoco Oil Belt, Venezuela, as a Case of Study
Authors: Landaeta G. , Lara V.
Published: May 2017

Exploration and production of heavy and extra heavy oil have always presented challenges that gradually have been overcome by reservoir engineers through the application of new technologies like downhole heating and diluent injection. However, it is recommended to conduct pre-assessment studies of these technologies in order to optimize resources associated with the implementation phase and subsequently with a large scale implementation of these technologies in the field.

One successful example where this pre-assessment study was applied, is the one performed in the Huyapari field located at the Orinoco Oil Belt, currently with more than 600 active horizontal wells where the productivity of the wells could be affected by the frictional pressure losses in the horizontal section. This is the reason why the main objective of this paper is to develop a reliable methodology to conduct a pre assessment study of the downhole heating cable technology by the integration of different methodologies such as analytical and deterministic analysis, operational evaluation, and numerical simulation.

Based on the results of the implementation of a downhole heating cable in the A-P10 well (producing with downhole heating cable since 2005) and the representation of these results by numerical simulation, it was established a procedure that takes into account the characteristics of the reservoir and some operational variables. The response in production of this well due to a slight increase in temperature in the horizontal section was evaluated through numerical simulation. Some other parameters such as changes in viscosity vs temperature, frictional pressure losses in the horizontal section, heating time were also investigated.

This procedure allowed the selection of the most prospective wells to install this technology, among more than 200 horizontal wells in the same reservoir; just 30% of the wells met all the requirements. This selection methodology added value to the well optimization strategy of the field saving considerable resources.

In conclusion, this study helped to represent the performance of the well when it has undergone a stimulation with a downhole heating cable, allowing to quantify the barrels associated with cumulative production and the developed reserves in different scenarios. This result could be of great importance for the Orinoco Oil Belt with its more than 297 MMMBP that represents today the largest accumulation of reserves of heavy and extra heavy oil in the world.
