− | Data currently available preclude a precise correlation of the East Breaks 160-161 field oils with a specific source rock. Therefore, the petroleum system(s) charging the ''Glob alt'' reservoirs is speculative. However, the data do suggest that the hydrocarbons originate from more deeply buried thermally mature rocks than those encasing the reservoir and therefore vertical migration has occurred. | + | Data currently available preclude a precise correlation of the East Breaks 160-161 field oils with a specific source rock.
