1. A TVD scheme for 3d unstructured grids applied to compositional reservoir simulation
Abstract In reducing the grid orientation effect for the numerical solution of partial differential equations, interpolation functions play an important role when the advective transport of the governing equations is considered. This is due to the fact that, in general, the unknowns are evaluated in the vertices of the elements and such properties must be ex

2. AN EOS-BASED NUMERICAL SIMULATION OF THERMAL RECOVERY PROCESS USING UNSTRUCTURED MESHES
Abstract In the past thirty years, the development of compositional reservoir simulators using an equation of state (EOS) has been addressed in the literature. However, the development of compositional thermal simulators in conjunction with the EOS formulation, in particular, has not been addressed extensively. In this work, a fully implicit, thermal, compos

3. Comparison of an impec and a semi-implicit formulation for compositional reservoir simulation
In compositional reservoir simulation, a set of non-linear partial differential equations must be solved. In this work, two numerical formulations are compared. The first formulation is based on an implicit pressure and explicit composition (IMPEC) procedure, and the second formulation uses an implicit pressure and implicit saturation (IMPSAT). The main goal

4. Avaliação do acoplamento explícito entre simulação de reservatório e sistema de produção / Evaluation of explicit coupling between reservoir simulator and production facilities system
Various methodologies to model the coupling of reservoirs and production systems have been applied in the oil industry in recent years due to the need to model properly the integrated solution of models that represent the flow of fluids through the reservoir to the surface. These methodologies are used to forecast production of multiple reservoirs, sharing p

5. Aplicação de redes neurais artificiais em simulação numérica do acoplamento poço-reservatório / Artificial neural networks applied to the numerical simulation of well-reservoir coupling
No presente trabalho, desenvolveu-se uma biblioteca para geração de redes neurais artificiais (NeuralLib) e aplicou-se a mesma para aproximação do acoplamento de escoamento em poços horizontais com reservatório. A biblioteca NeuralLib foi desenvolvida em linguagem C++. A arquitetura de rede gerada e utilizada foi a Multilayer Perceptron (MLP) com uma �

6. Estudo da perda de carga e calor no poço injetor no processo De drenagem gravitacional assistida por vapor (SAGD)
The oil companies in the area in general are looking for new technologies that can increase the recovery factor of oil contained in reservoirs. These investments are mainly aimed at reducing the costs of projects which are high. Steam injection is one of these special methods of recovery in which steam is injected into the reservoir in order to reduce the vi

7. NUMERICAL AND COMPUTATIONAL SIMULATION OF LOW DENSITY TURBIDITY CURRENTS FOR BASIN SEDIMENTATION / SIMULACAO NUMERICA E COMPUTACIONAL DE CORRENTES DETURBIDEZ DE BAIXA DENSIDADE PARA SEDIMENTACAO DE BACIAS
Turbidity currents occur in both natural and man-made situations. In agreement with some researchers, most of the world¿s oil reserves are stored in hydrocarbon reservoir built by turbidity systems. Because of the importance of these currents, this work proposes a consistent and efficient numerical method for simulations of turbidity currents for basin sedi

8. In-Situ combustion : insights on field project and numerical simulation at laboratory and field scale / Combustão In-Situ : considerações sobre projeto e simulações numéricas em escala de laboratório e de campo
Behavior forecast of reservoirs subjected to in-situ combustion is hard and empirical since besides geological complexities it is necessary to reproduce complex fluid models and several chemical reactions that are part of the process. The work flow for field project usually involves: 1) reservoir screening; 2) thermo-analytical experiments; 3) combustion tub

9. Development of natural gas fields under uncertainties / Desenvolvimento de campos de gas natural sob incertezas
This work studied the use of a methodology that allow calculate the risks and the value of information (VOI) in natural gas fields at initial stage of development. It is necessary to know the specific characteristics of recovery from a natural gas field, recognize uncertainties, both geological and the market and also the risks involved in investment decisio

10. A comparative study of implicit and explicit methods using unstructured voronoi meshes in petroleum reservoir simulation
This work presents a comparative study among three linearization schemes widely used in petroleum reservoir simulation, namely the Implicit Pressure Explicit Saturation (IMPES), Fully Implicit (FI) and Adaptive Implicit Method (AIM). Attention is given to the criterion used for switching from IMPES to FI and vice-versa. The black-oil model considering the oi

11. Simulação numérica do escoamento bifásico em meios porosos heterogêneos empregando uma formulação semi-implícita, imitadores de fluxo e o método dos volumes finitos / Numerical simulation of two-phase flow in heterogeneous porous media applying a semi-implicit formulation, flux limiter and finite volume method
A new numerical method is proposed for the solution of two-phase flow problem in petroleum reservoirs. The two-phase (water and oil) flow problem is governed by a pressure-velocity equation coupled to a saturation equation. For computational eficiency an operator spliting technique is used; distinct time steps can be used for the computation of transport and

Todos os cursos de água carream sedimentos com maior ou menor intensidade, sendo responsáveis pela redução da calha de rios e volume de reservatórios. O assoreamento dos reservatórios reduz sua vida útil, comprometendo os sistemas de geração de energia, de navegação, de irrigação, gerando problemas de ordem ambiental. Neste contexto, subsídios
