Analysis of oxygen production by applying in situ combustion

摘要

THAI (toe-to-heel air injection) is a process of enhanced oil recovery that consists of integrating the in situ combustion process with technological advances of horizontal wells drilling, and has not yet been applied in Brazil. Motivated by this context, this research aimed at studying the application of the THAI process in a semisynthetic reservoir, with characteristics similar to those found in the Brazilian Northeast. It was analyzed the air injection rate and produced oxygen, indicating that there is a limit to reach a good efficiency and minimized risk explosion.
