Prospect partner Murphy Oil said it and operator ExxonMobil came away with disappointing results from their Cutthroat-1 exploration well in Block SEAL-M-428 in the Sergipe-Alagoas Basin offshore Brazil. While the presence of hydrocarbons was not found, the partner group said it will continue to integrate the exploration well data into its regional subsurface interpretation efforts to better understand the exploration potential of its deepwater blocks located in the basin.

Cutthroat-1 was located nearly 90 km offshore Brazil and was drilled in 3094 m of water by the Seadrill West Saturn drillship. It is one of multiple prospects that the partner group has mapped in the basin.

ExxonMobil is the operator and holds 50% working interest in nine offshore SEAL blocks that span more than 6800 km2. Enauta Energia and Murphy Oil each hold a 30% working interest.
