Although a phase of energy transition is taking place in the world, with high growth in interest and consumption of renewable energies, oil is still the world's leading energy matrix. In Brazil, oil accounts for almost ...

The alternating injection of water and carbon dioxide (WAG-CO2) enhanced oil recovery method utilizes the injection of water and gas, normally miscible to improve production and oil recovery factor. With the discovery of ...

The pre-salt field is composed of large concentrations of light oil, with good quality and high commercial value, being an important historic mark in the last decades in Brazil and in the world. There are several reservoir ...

The pre-salt province is composed by large amounts of light oil and with good quality, a reality that puts Brazil in a strategic position facing the great demand for energy worldwide. In this province are the largest ...

In Brazil, the development of giant deepwater fields seems to have reached a new scale in 2006, with the huge Tupi discovery. As the water-alternating-gas (WAG) process can take advantage of the only two somehow abundant ...

After the decline of production from natural energy of the reservoir, the methods of enhanced oil recovery, which methods result from the application of special processes such as chemical injection, miscible gases, thermal ...
