This research studies the dissolution and mineralogical alteration caused by carbonated water injection (CWI) and its effects on the petrophysical properties (porosity and permeability) of limestone samples from the Mupe ...

During the last decade, there has been a significant development of oil and gas exploration in deep water in Brazil, along with the discovery of turbiditic reservoirs in Sergipe-Alagoas basin, as part of an entirely post-rift ...

MOSFiT (Magnetic Observatories and Stations Filtering Tool) is a python package to visualize and filter data from magnetic observatories and magnetometer stations. The purpose of MOSFiT is to automatically isolate and ...

In this work, we studied real and synthetic earthquake data from the viewpoint of Complex Networks and Nonextensive Statistical Mechanics (NESM). Through the analysis of spatial and temporal probability distributions between ...

n the last 60 years, the largest displacement of the magnetic equator (about 1100 km northwards) occurred in the Brazilian longitudinal sector. The magnetic equator passed by Tatuoca magnetic observatory (TTB, north of ...

Abstract Between 1993 and 2000, a total of 101 magnetotelluric stations were acquired by the National Observatory along the southeastern edge of the Parnaiba basin. The stations were distributed in 10 NW-SE profiles. The ...

Environmental magnetism evidences for longshore drift distribution of Fe bearing minerals between the Paraíba do Sul and Itabapoana rivers, state of Rio de Janeiro (Brazil) Over the last decades, studies based on sedimentary ...

The present work aims to develop a methodology that enables the prediction and harmonic analysis of ocean tides. Three computer codes were developed in Fortran. Two of them make the harmonic analysis to generate the fifteen ...

Reverse-time migration (RTM) is a seismic migration technique widely used when geological structures in subsurface presents high dip angles and velocity models are complex. It is in this cases that RTM migration take ...
