RIO DE JANEIRO—As Brazil’s output grows, mainly due to the success of its presalt fields, concerns about CO2 emissions caused by increased E&P activity have grown.
The country is among those that are aiming to limit greenhouse gas emissions, having signed the Paris climate agreement.
Researchers at the Research Centre for Gas Innovation (RCGI), which was created by a partnership between the University of São Paulo (USP), Royal Dutch Shell and the State of São Paulo Research Foundation, are looking for a method to significantly reduce the amount of CO2 emitted from southeastern Brazil.
The research encompasses two regions where there are rocks that could store the gas: the Paraná Sedimentary Basin and the Santos Basin. Oil is extracted from both of the basins’ presalt and post-salt layers.
The carbon capture and sequestration (CCS) project aims to verify types of rock capable of storing CO2. CCS, in its integrated form, involves capturing CO2, purifying, compressing and transporting CO2 to a sequestration site and injecting it into a geological reservoir or in the ocean.
