The NFW lies the southeastern part of the north south oriented Saturno prospect, which is about 20 km south of the Alto de Cabo Frio Central prospect and about 74 km east of the Libra field. The Saturno prospect was identified by the ANP during the 5th PSC Pre-Salt Bid Round and it is estimated it can have original oil in place (OOIP) of 7.5 Bbo and 1.8 Bbo of recoverable resources, if a 24% of recovery factor (RF) is assumed. As for gas, it is estimated the prospect might have original gas in place (OGIP) of 10.7 Tcfg and 5.4 Tcfg of recoverable, assuming a 50% RF.
