Block 5 is located north of the Kwanza's basin and 95% of its area is less than 200 meters deep.
E&P activity in this Block started in the 1960s, but so far no commercial discoveries were made. Overall this Block has 12 drilled wells - seven of those are dry wells and the remaining five despite yielding good oil samples were considered non commercial discoveries.
Risk factors to consider for this Block:
- Immatureness or lack of a source rock
- Uncertainty over the quality of reservoir
- Inefficiency of the seal in some prospect areas (sometimes with a decrease in thickness)
- Lack of structure seal
- Migration
