The company purchased the ownership for $2.33 billion, which allows it to assume full operatorship of the field located in Brazil’s Campos Basin, east of Rio de Janeiro.

The field, which currently has an FPSO and three fixed platforms, has been a key part of Equinor’s international operations since 2011, producing approximately 300 million bbl of oil.

PRIO serves as operator with 80% interest in the field. Equinor holds the remaining 20%.
