Title: Edson De Souza Leite: Innovator in Oil Recovery Technologies
Introduction
Edson De Souza Leite is a notable inventor based in Petröpolis, Brazil. He has made significant contributions to the field of oil recovery through his innovative patent. His work focuses on enhancing the efficiency of oil extraction from subterranean formations.
Latest Patents
Leite holds a patent for a process titled "Process for the selective controlled reduction of the relative water permeability in high permeability oil-bearing subterranean formations." This process aims to selectively reduce the water permeability in high permeability, oil-bearing formations while maintaining oil permeability. The method involves using a first layer of cationic polymer for sandstone reservoir rocks, followed by a brine spacer slug and a second layer made of anionic polymer and an anionic or non-ionic microgel. This configuration can be repeated to increase the thickness of the polymer layer, making it suitable for high permeability formations. For limestone rocks, the first layer consists of anionic polymer, while the second layer includes a suspension of cationic polymer and microgel. All polymers are injected as aqueous suspensions in brine or seawater. Leite's innovative approach has the potential to significantly improve oil recovery rates.
