Para efeito desse estudo foi utilizado o seriado House. A discussão sobre esse contexto de tomada de decisão é apoiada em autores como Cyert e March (1963), Simon (1965), Dubrin (1998), Miller, Hickson e Wilson (2004), Weber (1962), dentre outros. É uma abordagem qualitativa e o meio de investigação foi a lógica comparativa proposta por Serres (2003). Os dados foram coletados através de registros elaborados durante a apresentação de 50 episódios do seriado. Os dados indicam que o fato das decisões responderem a estruturas de poder, em muitos casos, e não permitem uma opção mais complexa que envolva os processos simultâneos e de incerteza (MORIN, 2001), como ocorrem no caso do seriado. Os principais fatores que diferem entre as decisões no contexto organizacional e no seriado são: o trabalho em equipe, meritocracia, responsabilização imediata pelos impactos das decisões e análise comparativa e horizontal das alternativas para construção de uma estrutura complexa da decisão.

Published: April 2016

Este artigo tem por objetivo tratar a questão do empreendedorismo social e sua relação com outras organizações e com o Estado brasileiro. São tratadas questões relacionadas à atuação de organizações do terceiro setor - campo onde atuam as Sociedades Civis de Interesse Público (OSCIPs) - e o empreendedorismo social. Foram analisados artigos e trabalhos que abordam o tema do empreendedorismo, notadamente sua origem e finalidades, bem como a atuações de determinadas formas de organizações, aqui compreendida como aquelas auxiliares nas ações dos empreendedores sociais para a realização de uma dada missão social. Faz-se ainda uma apresentação da reestruturação organizacional do Estado até a criação da Lei das OSCIPs, com ênfase para a atuação do terceiro setor, especialmente no que se refere à necessidade estatal de prover benefícios sociais e de gerar indicativos de participação da sociedade, fatos que levaram o Estado a redirecionar suas estratégias de atuação. Como resultado da revisão realizada, constatou-se a difusão do conceito de empreendedorismo social no Brasil por meio da criação de organizações representativas, bem como no acréscimo de recursos investidos no setor. Constatou-se ainda que, para suprir determinadas necessidades da população, é esperado que os empreendedores sociais mostrem capacidade de inovar, de usufruírem de oportunidades de mercado e de serem capazes de aperfeiçoar suas ações, com o objetivo de obter resultados, sejam eles qualitativos ou quantitativos. O processo de legitimação do conceito de empreendedorismo social aparece, assim, altamente relacionado à idéia de geração de benefícios sociais, o que é fundamental para que os empreendedores sociais possam se estruturar por meio de entidades, receber apoio e formar uma rede de atuação no campo social.

Published: April 2016

A idade – especialmente no caso de indivíduos mais velhos – tem sido um tema ainda pouco discutido pela área da Administração, apesar de o envelhecimento populacional já ter se revelado uma realidade no Brasil. Partindo da ideia de que as representações sociais sobre o que é ser velho e/ou idoso em nossa sociedade produzem e reproduzem situações de discriminação e preconceito que levam a desigualdades sociais torna-se pertinente refletir sobre como as ações e práticas organizacionais estão ao mesmo tempo afetando e sendo afetadas pelo envelhecimento intensificado da população e, ainda, como os pesquisadores e acadêmicos da área estão abordando estes temas. Realiza-se, neste artigo, um levantamento das publicações, na área da Administração, a respeito do tema envelhecimento, a fim de identificar como este assunto tem sido abordado pelos estudos organizacionais. Partiu-se da contextualização do processo de envelhecimento e de como este fenômeno vem ocorrendo no Brasil, delineando também um panorama dos estudos sobre o tema. Em relação ao método, optou-se pela meta-análise qualitativa. A coleta de dados foi realizada nos anais do Encontro Nacional dos Programas de Pós-Graduação em Administração – ENANPAD – (de 1997 a 2011), em todas as seções temáticas. Para a busca, utilizaram-se as seguintes palavras-chave: envelhecimento, velhice, idoso (a), velho (a), terceira idade, quarta idade, aposentadoria. Após a análise de 26 artigos, os resultados revelaram que o fenômeno tem sido pouco explorado pela Administração. As áreas de trabalho de Gestão de Pessoas e Marketing concentram a maioria dos estudos publicados, nos quais se pode identificar maior direcionamento para temáticas como aposentadoria e comportamento do consumidor.

Published: April 2016

Abstract
This study deals with the development of a methodology for making low compressive strength cores used in an experimental investigation of the Cold Heavy Oil Production with Sand (CHOPS) process. An experimental setup was designed and built to investigate the effect of rock compressive strength as well as flow parameters, such as oil viscosity, net and total confining pressure and injection rate on core permeability. The approach was to optimize the value of a response variable by changing the values of the affecting factors.
Sand blends were prepared by varying the ratios of aggregate, cementing material and water to prepare synthetic cores. An experimental unit was built to simulate wormhole propagation during the CHOPS process, where oil, at an ambient temperature, was injected at varying rates of 0.5–10 ml/min into 2-inch × 4-inch cores under differential confining pressures of 500 and 1000 psia. The pressure drop across the core was monitored throughout the process.
When non-swelling clay is used as a cementing material compared with actual cement to make synthetic core, the compressive strength of the samples fall dramatically by 64%. Two factors were considered in the experiments: Oil Viscosity (370 and 690 cp) and Injection Rates (0.5 and 3 ml/min) at a net confining pressure of 500 psi, less than the compressive strength of the core. The experimental results demonstrated that at lower pore volumes of injection, the permeability of the core for high viscosity oil is almost 11.2% greater than for low viscosity oil. Also, we used design of experiment approach and developed regression models for permeability based on values recorded at specific pore volumes injected for different injection rates and oil viscosities. It was found that at a constant confining pressure for all rates, at lower pore volumes injected, 99.8% of the variance in permeability can be explained by oil viscosity, injection rate and their interaction. At higher pore volumes injected, the variance in permeability that can be explained by oil viscosity, the injection rate and their interaction is only 40.63%.
An Improved Approach for Sandstone Reservoir Characterization

Published: April 2016

Abstract
This paper presents a field scale reservoir characterization for a late Pennsylvanian clastic reservoir at the Farnsworth Unit (FWU), located in the northeast Texas Panhandle on the northwest shelf of the Anadarko basin. The characterization is undertaken as part of a Phase III project conducted by the Southwest Regional Partnership on Carbon Sequestration (SWP). The target unit is the upper most Morrow sandstone bed (Morrow B Sand). Extensive data acquired from FWU was used to improve previously constructed static and dynamic models.
The Morrow B reservoir was deposited as fluvial low-stand to transgressive clastic fill within an incised valley. It is predominantly, subarkosic, brown to grey, upper medium to very coarse sands and fine gravels with sub-angular, to sub-rounded poorly sorted grains either planar to massively bedded. It was shown that primary depositional fabrics have less effect than post depositional diagenetic features do on reservoir performance, although subtle variations in deposition may have had some effect on later diagenetic pathways.
Three new wells were drilled for the purpose of field infilling and characterization. Cores and advanced wire-line logs from these wells were analyzed for stratigraphic context, sedimentological character and depositional setting in order to better predict porosity and permeability trends within the reservoir. Structural modeling was conducted through the integration of depth-converted 3D seismic data with well log data to create the framework stratigraphic intervals. This information, together with additional core, UBI image logs and an improved hydraulic flow unit methodology (HFU) was used to characterize and subsequently create a fine scale lithofacies based geological model of the field.
Core and log analysis allowed subdivision of the target interval into Hydraulic Flow Units (HFUs). The HFU approach enhanced core analysis and was used to elucidate porosity–permeability correlations. This methodology proved to be an exceptional approach to assigning permeability as a function of porosity during petrophysical modeling.
The integrated approach of combining seismic attributes with core calibrated facies and the HFU methodology was able to better constrain uncertainty within inter-well spacing and accurately quantify reservoir heterogeneity within FWU. The approach illustrated in this study presents an improved methodology in characterizing heterogeneous and complex reservoirs that can be applied to reservoirs with similar geological features.

Abstract
This paper presents an optimization methodology for CO2 enhanced oil recovery in partially depleted reservoirs. A field-scale compositional reservoir flow model was developed for assessing the performance history of a CO2 flood and optimizing oil production and CO2 storage in the Farnsworth field unit (FWU), Ochiltree County, Texas.
A geological framework model constructed from geophysical, geological and engineering data acquired from FWU was used for the reservoir modeling. A laboratory fluid analysis was tuned to an equation of state and subsequently used to predict the thermodynamic minimum miscible pressure (MMP). An initial history calibration of primary, secondary and tertiary recovery are conducted as the basis for the study.
After a good match was realized, an optimization model with proxy was constructed with an objective function that maximized both oil recovery and CO2 storage. Experimental design was used to link uncertain parameters to the objective function. A reduced order proxy model was necessary to reduce computational cost. Control variables considered in this study included: CO2 purchase, recycled CO2, water alternating gas cycle and ratio, infill wells and bottomhole pressure of injectors and producers. Polynomial response surface methodology was used to create the proxy model based on training simulations. This involved an iterative process until a validated surrogate model was achieved. A sensitivity analysis was first conducted to ascertain which of these control variables to include in the reduced order model. A genetic algorithm using a mixed-integer capability optimization approach was employed to determine the optimum developmental strategy to maximize both oil recovery and CO2 storage.
The proxy model reduced the computational cost significantly. The validation of the reduced order model ensured accuracy in the dynamic modeling results. The prediction outcome showed the robustness and reliability of the genetic algorithm in optimizing oil recovery and CO2 storage.
The reservoir modeling approach used in this study showed an improved way of optimizing oil production and CO2 storage within partially depleted oil reservoirs such as FWU. This study serves as a benchmark for potential CO2–EOR projects in the Anadarko basin and/or geologically similar basins throughout the world.

Published: April 2016

Abstract
A new dual-lateral subsea well in the Aasgard Field (Haaland et al 1996) was recently completed with Multilateral Drilling Stimulation Technology (MDST) in one of the lateral legs. MDST was developed in a Joint Industry Project (JIP) with Fishbones AS, Statoil Petroleum AS, Eni Norge AS, Lundin Norway AS and Innovation Norway. The project was also supported by the Research Council of Norway. The technology stimulates wells by creating a large number of laterals from the wellbore into the formation. The laterals are drilled utilizing small diameter tubes with drill bits and turbines which are conveyed into the well as integral parts of an open hole liner. For the laterals' drilling process, drilling fluid is circulated for a few hours using the rig pumps. This circulation turns the turbines which drives the bits into the formation creating the laterals. MDST was qualified to Technology Readiness Level 4 (TRL4), Qualified for First Use, as part of the JIP. A total of 144 laterals were drilled from the mainbore to increase productivity from the tight sandstone formation. The target reservoir, named Upper Garn, is comprised of an undeveloped oil bearing tight sandstone with intermittent cemented stringers overlaying a developed gas formation. MDST was selected as the stimulation method with an objective to increase productivity without the risk for connecting the well with the gas formation. For the drilling and completion operations, a semi-submersible rig was used. The production results indicate that MDST increased productivity in this application.
Life After SAGD – 20 Years Later
Authors: Ali S. M. 
Published: April 2016

Abstract
I presented a paper "Is There Life After SAGD?" at the 1996 Western Regional Meeting1. The paper was published and elicited some 20 discussions. Today, SAGD - Steam-Assisted Gravity Drainage - is a commercially successful recovery method in Canada, if the price of oil is right. The subject of this paper is what we have learned in the past 20 years, and what is the future of SAGD in oil (tar) sands and heavy oil exploitation.
At last count there were 18 SAGD projects in Alberta, and none anywhere. Bitumen production by SAGD is about 800,000 B/D. There have been failures also - in Alberta, California, Venezuela, etc.
The oil recovery factor can be as high as 60%, depending on how one defines it, and as low as 10-20%. The steam-oil ratio varies from 1.6 Bbl steam/Bbl oil, to 8 Bbl/Bbl. (Note that these are based on 95% downhole steam quality and are to be multiplied by ~1.3 to compare with typical steam injection SOR's). There are large variations even within the same project. The heat production can be as much as 50% of that injected. The desired downhole steam quality is 100%. Thus SAGD is a unique recovery method, but its application requires great caution.
Some of the assertions of 20 years ago still apply. A few new aspects of SAGD have come to the fore. Many variations of the basic process have been proposed and tested. Many have failed. In some of the less successful projects, solvents and other additives are being injected with steam to improve performance.
The attractive features of SAGD are described, and application guidelines are offered, based on failures. SAGD is here to stay, but what are the limits to application? This is the focus of the paper.
Maximizing Performance of Residue-Free Fracturing Fluids Using Nanomaterials at High Temperatures

Published: April 2016

Abstract
Polysaccharide-based fluids such as guar fluids are commonly used in hydraulic fracturing operations, primarily because of their abundance, relative low cost, and capability to work at up to 350°F when formulated at high pH. However, one notable disadvantage for most guar is the insoluble residue which tends to cause permeability reduction. Another disadvantage for using guar-based fluids at high pH is the tendency of forming divalent ion scales at high pH.
In general, thermally stable synthetic polymers, such as acrylamide based polymers are considered to be residue-free. They can be used for preparing fracturing fluids around 300-450°F or more. However, high dosage of acrylamide based polymers may still cause formation damage due to factors such as incomplete degradation. This paper demonstrates the advantage of using selected nanomaterials to enhance the thermal stability of the crosslinked synthetic fluids and to reduce the polymer loading. With addition of a small amount of nanomaterials (e.g. 0.02wt%), the polymer loading used at temperatures 300-450°F can be reduced dramatically compared to other existing commercial products.
This paper presents results from rheological studies which demonstrate superior viscosity performance and excellent thermal stability of this novel fluid system enhanced with the nanomaterials at this high temperature range. For example, at 30 pounds per one thousand gallons (pptg) polymer dose, the fluid viscosity stays above 500cP (at 40 s-1 shear rate) at 350°F for more than 3 hours. This fracturing fluid system has therefore shown sufficient proppant carrying and transporting capability. The fluids can be efficiently broken to allow for good cleanup using oxidative breakers. Proppant-pack conductivity tests for a 300°F fluid formulation gives 83% regained perm proving the low damaging potential of this type of fluids. Using low loading of residue-free polymer therefore results in better cleanup, reduced formation damage, and enhanced production rates.
The nanomaterial-enhanced fracturing fluid system based on the synthetic acrylamide copolymers demonstrates the unforeseen combination of a number of advantages including low polymer loading, excellent high-temperature performance, and high retained permeability.
Pilot Test and Economic Analysis of a Wellhead Produced Water Purification System Based on Humidification and Dehumidification Using Co-Produced, Solar, and Waste Heat
Authors: Balch Robert , Abdallah Issah , Garcia Leonard , Cercone David 
Published: April 2016

Abstract
This paper presents field testing results and economics analysis at pilot scale for a humidification- dehumidification (HDH) process, described in SPE 169526, and to demonstrate that the process is viable and cost-effective, using solar, latent geothermal, and waste heat to augment the process for continuous operation.
The HDH process drops produced water heated to 145–185°,F down chambers with up-blowing ambient air which humidifies the air at elevated temperatures to relative humidity &gt;99%. The water- laden air then drops into adjacent cooling chambers and fresh water condenses out. Additional fresh water yield is achieved by using a secondary air-cooled condenser. To accomplish pilot test goals, a field scale prototype was constructed and tested at a field test site near Artesia, New Mexico, to determine operational parameters with solar heating, and then at the Federal 00 well in Eddy County, New Mexico, an oil well that produces ~20 BBLs of water per day, to test unattended operation and economics.
The HDH unit was sized for the Federal 00's water production and can process 51 BBls of produced water per day. The field setup utilizes latent geothermal heat in the produced and heat is added to the water using an array of 16 flat plate solar panels. Heated water passes into an insulated storage vessel, which then feeds the HDH unit. When the solar panels are not generating heat, produced water is fed directly into the heated storage. At night or on cloudy days, additional heat can be supplied to the storage tank by burning waste gas. An Arduino controller manages the process flow, switches fluid flow as needed, and monitors tank levels. The HDH unit can purify ~20% of the inlet water on each pass, and the outlet concentrate, at ~125°F, can be cycled back into the hot water storage tank.
The system was tested in summer and winter conditions. Winter conditions have drier inlet air, but less solar energy, and conversely summer has wetter inlet air, but more available solar heating. Summer tests yielded ~8-9 BBLs per day of purified water, and winter tests produced ~11 BBLs per day, for an annualized average of 10 BBLs per day, potentially cutting the disposal needed for the Federal 00 in half. Purification costs are primarily from electrical use of small pumps, a blower, and an air-cooled condenser. These average $3.82 per day, corresponding to ~$0.55 per barrel in summer and ~$0.35 per barrel in winter to purify water. Cost offsets from selling the fresh water and reduced disposal costs yielded an 85% reduction in annualized produced water handling costs.
