1. Estudo de propriedades petrofísicas de rochas sedimentares por Ressonância Magnética Nuclear / Petrophysical properties study of sedimentary rocks by Nuclear Magnetic Resonance
The Nuclear Magnetic Resonance (NMR) technique is one of the most versatile techniques for scientific research, specially for the study of dynamics, structure and conformational of materials. In particular, its application in oil science is one of its first routine applications. Methodologies developed specifically to match this scientific community proved t

2. A mathematical model for isothermal heap and column leaching
Leaching occurs in metals recovery, in contaminated soil washing, and in many natural processes, such as fertilizer dissolution and rock weathering. This paper presents a model developed to simulate the transient evolution of the dissolved chemical species in the heap and column isothermal leaching processes. In this model, the solid bed is numerically divid

3. DESENVOLVIMENTO DE EQUIPAMENTO E METODOLOGIA DE TESTES PARA AVALIAÇÃO DA INTERAÇÃO FOLHELHO-FLUIDO DE PERFURAÇÃO / DEVELOPMENT OF EQUIPMENT AND TESTING METHODOLOGY TO EVALUATE ROCK-DRILLING FLUID INTERACTION
The drilling of oil wells through shales, which constitute the majority of rocks in the stratigraphic column, may present instability problems due to physico-chemicals interactions between the drilling fluids and these rocks. The costs associated to the solution of these problems are very high and, depending upon the intensity of these problems, wells can be

4. AVALIAÇÃO DA INFLUÊNCIA DA INTERAÇÃO ROCHA-FLUIDO NA ESTABILIDADE DE POÇOS / ESTIMATE OF THE INFLUENCE OF ROCK-DRILLING FLUID INTERACTION ON WELLBORE STABILITY
Os problemas na perfuração associados à instabilidade do poço são geralmente agravados quando camadas de folhelho são atravessadas, as quais constituem uma alta porcentagem do total das rochas perfuradas no mundo. O folhelho, quando submetido às tensões in situ, pode atuar como uma membrana semipermeável à passagem de íons através do seus poros.
