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. 3D COMPOSITIONAL RESERVOIR SIMULATION IN CONJUNCTION WITH UNSTRUCTURED GRIDS
Abstract In the last decade, unstructured grids have been a very important step in the development of petroleum reservoir simulators. In fact, the so-called third generation simulators are based on Perpendicular Bisection (PEBI) unstructured grids. Nevertheless, the use of PEBI grids is not very general when full anisotropic reservoirs are modeled. Another p

3. 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

4. Simulação computacional do escoamento em bombas de cavidades progressivas
O uso de bombas de cavidades progressivas (BCP) para elevação artificial de petróleo em poços de baixa a média profundidade está se tornando mais comum na indústria do petróleo devido, dentre outras características, à sua habilidade de bombear óleos pesados, produzir óleo com grandes concentrações de partículas sólidas, e tolerar grandes fra�

5. Análise de esquemas numéricos de cinco e nove pontos para malhas tipo corner-point
In petroleum reservoir simulation is common to use numerical calculations that simplify the governing conservation equations in order to reduce the computational time, increase the simulator robustness and simplicity. However, these approximations may result in considerable errors. A classic type of this approximation, studied in this work, is the five point

6. Simulação de reservatórios de petróleo utilizando o método EbFVM e multigrid algébrico
Este trabalho propõe uma metodologia numérica para a simulação do escoamento multifásico em reservatórios de petróleo utilizando o Método de Volumes Finitos baseado em Elementos (EbFVM). Este método emprega malhas não-estruturadas com elementos triangulares e/ou quadrangulares, o que lhe confere maior flexibilidade e generalidade. Os poucos método
