Abstract :
Block 15/06 is located in the Angola deep sea, which belongs to Lower Congo basin. The primary source rock of the Block is the marine shale of Iabe and Landana formation of Upper Cretaceous & Lower Tertiary. The main reservior of supra-salt strata is Tertiary turbidite channel sandstone. Oil-bearing strata of the block are Miocene and Oligocene formations, mainly Miocene. The cap rock is the marine mudstone and shale of Tertiary. The type of trap is structure-lithology complex which is on the background of salt structure. The main factors of hydrocarbon accumulation are Salt dome and faults. Faults are the main channels for hydrocarbon migration.
