Ene Basin Petroleum Systems
Baseline Resolution & GSI
The Ene Basin is located within the sub-Andean fold-thrust belt in the foothills of Eastern Cordillera of Peru. The Ene Basin is designated as a basin largely due to the presence of the Tertiary sediments. These Tertiary sediments, however, only represent the remnants of younger sediments within the intervening lows between WNW-ESE trending thrust sheets that expose Cretaceous and older units .
The Ene Basin occupies an area of about 5545 km2 (554,527 hectares). The basin was divided by Elf (1997a) into three sectors, namely, the northern, central, and southern Ene sub-basins based on the differences in structural style, gravimetric and magnetic data, and microseismicity is the geological map of the Ene Basin.
The northern Ene sub-basin is bounded to the east by the San Matias thrust that abuts against the Pachitea Basin in the northern part, and against the Shira Mountain (Pajonal High) in the southern part. The southern margin of the northern Ene sub-basin is roughly the northwestward prolongation of the NW trending Tambo Fault zone.
The central Ene sub-basin is bordered to the west by the Internal Zone (where Jurassic and Permo-Carboniferous series outcrop), and to the north and east by the Tambo Fault Zone. Its central part is occupied by a huge Tertiary syncline. The synclinal axis crosses through the limit of the central Ene sub-basin into the northern Ene sub-basin.
