Summary • Location • Infraestructure and Operational Conditions • Exploratory Background • Tectono-Stratigraphy Evolution • Petroleum Systems • Plays • Analogous Exploratory Sucesses • Area on Offer • Final remarks Final remarks The New Frontier Basin with the presence of structural features / stratigraphic prominent; Existence of a western graben (NE-SW), with about 3,500 m of thickness in the Cupe region with great possibility of the generation of hydrocarbons; The "Sub-Basin Plateau“ Pernambuco basin have thicknesses on the order of 6,000m. Existence of an evaporite sequence halocinetics and structures that affect the post-rift sequence. Final remarks There is evidence of the existence of a petroleum system (thermogenic) active in Pernambuco portion of the basin. The "Sub-Basin Plateau” is the main area potentially generating of HC in the basin (greater thickness and burial for the syn-rift section). It is expected a lateral migration to medium / large distance to potential structural traps present in the High Plateau (mostly in the syn-rift section). Associated Structures with magmatic features may also be possible targets for exploration; Secondly, maybe consider probable stratigraphics traps presents in the section K upper/ Tertiary age in "Sub-Basin Plateau" (conditioned the existence of faults).
