Conditional truncated plurigaussian simulation; Simulacao plurigaussiana truncada com condicionamento. The goal of this work was a development of an algorithm for the Truncated Plurigaussian Stochastic Simulation and its validation in a complex geologic model. These sets were used to condition the simulation and to refine the estimates of the non-stationary matrix of facies proportions, used to truncate the gaussian random functions RF.
In this new model its possible to use several facies with different spatial structures, associated with the simplicity of TG. These characteristics of spatial structures of sedimentary facies served to evaluate the simulation model. Two independent gaussian RF were used, as well as an ‘erosive model’ as the truncation strategy. Also, non-conditional simulations were proceeded, using linearly combined gaussian RF with varying correlation coefficients.
It was analyzed the influence of some parameters like: It was showed, step by step, using an example, the theoretical model, and how to construct an algorithm to simulate with the Truncated Plurigaussian Model. The conclusion of this work was that even with a plain algorithm of the Conditional Truncated Plurigaussian and a complex geological model it’s possible to obtain a usefulness product.

En particular, este caso en el que se ha acogido el estudio es el personaje Leonard Shelby Lenny del film de culto Memento de Christopher Nolan. In this paper we present a new claim count distribution with overdispersion. The new distribution is obtained by mixing the p parameter in the binomial distribution with a 0,1 truncated exponential distribution. The new distribution can be considered as an alternative to the classical Poisson, binomial and geometric distributions.
An error occurred.
Some properties of the new distribution and some applications in the field of automobile insurance are given, by fitting empirical cla Transport simulation of mangoes irradiated for exportation; Simulacao do transporte de mangas irradiadas para exportacao. It had been studied the effect of the ionizing radiation gamma in mangoes for exportation, simulating the stage of preservation of the fruit during its transport, through the refrigeration in cold chamber. In a first stage they had been analyzed through loss of weight, pH, treatable acidity, soluble solid, texture and decomposition.
Later, sensorial analyses had been become fulfilled alterations of color, odor, flavor, texture.
The assays had been carried through in two stadiums of maturation of the fruits, that is, 2 and 3, with the intention of studying optimum point of harvest for the best dosage of irradiation. The results disclose together that the treatment of the mangoes Tommy Atkins in the dose of 0,75 kGy was significant, with the weiubll in stadium 2, for the retardation of the matureness and consequent profit of time for the exportation. Modelling and simulation of a photovoltaic generator; Modelagem e simulacao de gerador fotovoltaico.
Cabral, Claudia Valeria T. A photovoltaic generator is subject to diverse variations in solar intensity, ekemplos temperature or load, which alter the optimal operation point.
Thus, one must analyze its behavior regarding such variations in order to optimize its functioning. This paper aims at modeling a photovoltaic generator regarding the features provided by the manufacturer and simulate it, using, for that purpose, simulation and curve digitalisation programs Simulink of Matlabanalyzing its distdibucion with regard to the temperature and solar intensity variation, comparing the obtained curves to those provided by the manufacturer.
The obtained results were satisfactory, the model used being valid for photovoltaic generators simulation. Numerical simulation supports formation testing planning; Simulacao numerica auxilia planejamento de teste de formacao.
A well resyeltos is an operation that allows the engineer assessing reservoir performance and fluids properties by measuring flow rates and pressures under a range of flowing conditions. In most well tests, a limited distribuucion of fluid is allowed to flow from the formation being tested.
The formation is isolated behind cemented casing and perforated at the formation depth or, in open hole, the formation is straddled by a pair of packers that isolate the formation.
During the flow period, the pressure at the formation is monitored over time. Then, the formation is closed or shut in and the pressure monitored at the formation while the fluid within the formation equilibrates. The analysis of these pressure changes can provide information on the size and shape of the formation as well as its ability to produce fluids. The flow of fluid through the column test causes your heating and hence its elongation. Several factors affect the rate of exchange of heat as well and the characteristics of the fluid, the flow of time and the flow and the existence of deep water.
The prediction of temperature over well, in its various components, and the effect caused in the column test is not a trivial task. Some authors, for example, describe a method of calculating the behaviour of columns of production, making it simpler variation of constant temperature throughout the entire column, a fact that this does not occur in practice. The work aims at presenting the advantages of using the numerical simulation in determining the efforts and corresponding movements of the column of test of formation.

We have investigated the effect of temperature in penetration of an inviscid fluid into a porous media saturated with a very high viscous fluid. Gradient of temperature is applied across the medium. The viscosity of the defending fluid is considered as an exponential-like function with temperature. This scheme represents a small fraction of a heavy oil reservoir where steam injection is applied. The results show that the recovery of the viscous fluid is a hyperbolic tangent function with the difference of temperature, where it has a maximum recovery for high gradient.
Our results show, also, that the recovery efficiency can increase substantially with the gradient of temperature. Simulation of batch adsorption systems; Simulacao de sistemas adsorvedores operando em batelada. One of the treatments used to adequate the wastewater from petroleum industry according to environmental laws, is the treatment by the adsorption process.
Powdered activated carbon is the commonly used adsorber material, for this great affinity with various organic compounds.
But there are alternative adsorber materials that can substitute activated carbon, with a low cost, and limited applicability. In this work, will be used the software resulting from Efli project, developed at Federal University of Technology – Parana, to compare the alternative adsorber materials oil shale compounds and fluid catalytic cracking efficiency to that of activated carbon.
Dynamic solution of vessel depressuring; Simulacao dinamica de despressurizacao em vasos. Vessel depressuring is an important phenomenon on chemical and petrochemical processes, specially those related to oil and gas exploration, production and processing. The correct modeling of this phenomenon and prediction of the temperatures, mass and thermal rates involved is essential to the adequate design of the equipment, materials specification and safety standards assurance.
To fulfill these requirements, we developed a method to simulate the phenomenon of depressuring. In this approach, the dynamic process is discretized along time, being calculated at each interval the conditions inside the vessel, material flow and heat exchanges with the environment, through mass and energy balances and thermodynamic equilibrium calculation. The method can include different models to calculate heat exchanges and flow through the relief valve, and new methods can be incorporated if necessary.
The efficiency of the method was verified by comparing its results with the ones obtained by market-leaders process simulators, when it was proved the robustness of the method and precision of the results. Multi-scale approach in numerical reservoir simulation; Uma abordagem multiescala na simulacao numerica de reservatorios. Advances in petroleum reservoir descriptions have provided an amount of data that can not be handled directly during numerical simulations.
This detailed geological information must be incorporated into a coarser model during multiphase fluid flow simulations by means of some upscaling technique. In this work, it is proposed a multi-scale computational model for multiphase flow that implicitly treats the upscaling without using pseudo functions.
By solving a sequence of local problems on subdomains of the refined scale it is possible to achieve results with a coarser grid without expensive computations of a fine grid model. The main advantage of this new procedure is to treat the upscaling step implicitly in the solution process, overcoming some practical difficulties related the use of traditional pseudo functions.
Passive constituents dispersion simulation in Solimoes river; Simulacao de dispersao de constituintes passivos no rio Solimoes. This work presents a passive constituents transport simulation in Solimoes river, that is part of Piatam Project modeling activities.
An ADCP section was used as initial condition in one of the model boundaries. The velocity field was compared with five ADCP section collected along the simulated river and similar velocity magnitude was observed.
Simultaneously to the ADCP data collection an in situ observation has been done to observe the oil spill spreading, using popcorn liberated in the river. The popcorn spill trajectory observed was similar to the one modeled. Simulation model of a micro turbine; Modelo para simulacao de uma microturbina. The introduction of distributed generation DG units in the electric power system has been surrounded by many promises and uncertainnesses.
Hence, new simulation tools are needed in order to assess the issues and the benefits related to the connection of DG in the electric power system. In this paper will be presented and simulated a model of a micro turbine, a new and emerging distributed generation technology. Salt mechanical behavior numeric simulation in oil wells; Simulacao numerica do comportamento mecanico do sal em pocos de petroleo.
Drilling incidents such as stuck pipe and collapsed casing string take place when when some type of salt formations are drilled because of the high pronounced plastic behavior of the salt and the creep behavior as a function of this type of rock. The deeper the salt is found, the earlier and more intense the troubles caused by salt creep will be evidence.

Methodology for transient simulation of a small heliothermic central station; Metodologia para simulacao transiente de uma pequena central heliotermica. The final steps of generating electricity from concentrated solar power technologies are similar to conventional thermal processes, since steam or gas is also employed for moving turbines or pistons. The fundamental difference lies on the fact that steam or hot gas is generated by solar radiation instead of fossil fuels or nuclear heat.
The cheapest electricity generated from solar energy has been achieved with large-scale power distribucionn based on this concept. Computer simulations represent a low-cost option for the design of thermal systems. The present study aims to develop a methodology for the transient simulation of a micro-scale solar-thermal power plant kWe resueltox should be appropriate in terms of accuracy and reuseltos effort.
The facility ehemplos can optionally operate as a cogeneration plant producing electric power as well as chilled water. Solar radiation is collected by parabolic troughs, electricity is generated by an organic Rankine cycle and chilled water is produced by an absorption cooling cycle.
The organic Rankine cycle is of interest because it allows for a plant with relatively simple structure and automated operation. The parabolic trough field component is based on an experimental efficiency weibulo of the solar collector. In the case of distribycion Rankine and absorption cycles, the components are based on performance polynomials generated with EES from detailed thermodynamic models, which are calibrated with performance data from manufacturers.
Distinct plant configurations are considered. An optimization algorithm is used for searching the best operating point in each case. Results are presented for the following Brazilian sites: Fortaleza, Petrolina and Bom Jesus da Lapa.
The latter offers the highest global plant performance.
An rresueltos about the influence of the thermal storage on the annual efficiency and capacity factor shows trends that are similar to results found in literature. An analysis with the absorption cycle demonstrates that it is not feasible to recover waste heat from the Rankine cycle condenser in order to produce chilled water.
The simulation of the facility proves to be numerically stable and appropriate for analyzing the dynamic behavior and the long-term performance of a micro-scale solar-thermal power plant.
