A capacidade do profissional contabilista em gerar informações é altamente reconhecida, porém, a de externá-Ias não se repete com a mesma eficiência. Esta menor capacidade em tornar pública suas aptidões e conhecimentos pode comprometer a valorização do profissional em um ambiente altamente competitivo. No entanto, o avanço tecnológico, o advento da globalização, a difusão massificada da informação criou um ambiente favorável para correlacionar o marketing com os serviços profissionais e a capacidade potencial de influenciar a valorização da profissão contábil. O objetivo deste artigo é mostrar que o marketing contábil deve ser um instrumento de ajuda no enfrentamento de mudanças ambientais rápidas, de ampliar o relacionamento com os clientes atuais, atrair novos clientes, melhorar a eficiência dos esforços para o desenvolvimento de seus negócios e satisfazer as necessidades do cliente. Sua função é tornar a empresa mais competitiva, sem abalar a ética da profissão. Ainda que exista uma infinidade de contabilistas absolutamente contra a prática da comunicação, entendendo-a como um artifício antiético e de pouco merecimento, todos aplicam diariamente conceitos e técnicas de marketing, mesmo sem o perceber. O estudo caracteriza-se como exploratório e objetiva descrever as características e a forma de utilização do marketing pelas organizações contábeis da cidade de Chapecó-SC. Os dados foram coletados por meio de questionário aplicado em 37 organizações. Os resultados obtidos pela pesquisa demonstram que alguns dos profissionais contábeis possuem uma certa retração no que diz respeito à prática de marketing.
Summary One of the main problems regarding the use of the artificial-lift method of electrical-submersible-pump (ESP) systems is the presence of gas in the pump. This paper presents and describes an analysis of ESP systems with a stage-by-stage calculation to determine intake and discharge pressures to adjust total dynamic head (TDH) for each stage of the pump. The modeling was designed to acknowledge free gas in the pump, and iterative calculations are applied to recalculate, for each stage, fluid characteristics and physical properties, such as viscosity, density, formation volume factor (FVF), surface tension, solubility ratio, gas/oil ratio (GOR), and other flow characteristics along the tubing, such as temperature and pressure. Developed modeling validation was achieved by comparisons in two scenarios. In the first one, fixed values of intake pressure and changeable values of GOR were used to assess gas effect. In the tests for the second scenario, fixed values of GOR and changeable values of intake pressure were used. Necessary research was conducted through a developed computational tool used to size ESP components. The results were different from those obtained with the usual calculations, and it may be implied that the developed modeling is more accurate to determine parameters related to this artificial-lift method. Also, the results were more consistent and closer to the actual behavior of multiphase-flow phenomena within the tubing because each stage has its characteristics individually evaluated. These observations may have an effect on the number of pump stages and influence in choosing the adequate equipment of the system.
This paper proposes a numerical solution for the calculation of the downhole dynamometer card for deviated wells equipped with sucker-rod pumping. The solution shown is based in the model developed for the project of sucker-rod pumping systems considering three-dimensional trajectories. The results shown indicate that the incorporation of the three-dimensional model to the algorithm allows the adequate calculation of downhole dynamometer cards for vertical and deviated wells. The model enables the estimation of important productive parameters for any sucker-rod pumping system, such as flow rate and intake pressure, besides calculating significant data for deviated systems, such as lateral load acting throughout the rod string.
