The importance of field recovery technique

Enhanced Oil Recovery (EOR) also called tertiary recovery is a term used for techniques that increase the amount of oil that cannot be extracted otherwise from a field. Its use causes 30% to 60% or more of the original oil to be extracted, in 20% to 40% using primary and secondary recovery.

With the decline in oil and gas discoveries in recent decades, it is believed that improved oil recovery will play a role in to meet energy demand in the coming years. Other than that, the sector that is present in maritime or land fields, has been innovating each time injection CO2, high pressure air injection (HPAI) and flood of Chemical.

According to the IBP website (Brazilian Institute of Petroleum, Gas and Biofuels), the National Agency for Petroleum, Natural Gas and Biofuels (ANP) already sees unique opportunities to revitalize activities in land fields and shallow water fields. In addition, the increase in recovery of mature fields in primary or secondary production will be critical to meet the growing energy demand in the coming years.
