Camamu Basin - Brazil - 2005

Camamu Ph 1-2 PSDM 3D

The Survey covers the prospective and underexplored Camamu-Almada Basin
Website Map for Survey Camamu Ph 1-2 PSDM
Presalt section as well as Tertiary and Cretaceous Turbidites. BP Pitanga well tested source rock and partial section. Additional section and targets at similar depths and deeper.
Furthest north Brazilian basin with salt involvement. Presalt section is untested and could be either carbonates or clastics. The clastic analogue is the Dentale formation in northern Gabon. Turbidite play analogues are the Farfan, Barra and Moita Bonita discoveries in Sergipe-Alagoas.
The PSDM allows evaluation of a number of play fairways and play types.
