Brazilian oil company Enauta said on Monday it acquired the entire 23% stake held by QatarEnergy Brasil Ltda in some oil fields in the Campos Basin for a total value of $150 million.

In a securities filing, the company said that the transaction to acquire a stake in the Abalone, Ostra, and Argonauta oil fields, components of the so-called Parque das Conchas, was dated July 1, 2023, with $15 million disbursed at the signing.

The remaining amount will be paid in three installments, Enauta said, indicating that the deal still requires approval by Brazil's oil regulator ANP and antitrust watchdog CADE.

Parque das Conchas is operated by Shell, which holds a 50% stake, while the remaining 27% is owned by the Indian company ONGC.
