Brazil’s Petrobras expects to conclude key tests by the end of the month regarding the future use of its innovative Hi-Sep technology ahead of a planned application in commercial scale in the domestic Mero pre-salt field.

Hi-Sep is a Petrobras patented technology focused on dense separation of associated gas with carbon dioxide content through the use of subsea centrifugal pumps. It is expected to assist in the development of pre-salt fields with a high gas-to-oil ratio and contaminants.
