Geology

• The field is in an east-northeast-west-southwest-trending asymmetric anticline, which formed in a foreland setting bounded by reverse faults to the north and south and srike-slip faults east and west. Sandstones of the Caratas Formation of Eocene age and Los Jabillos and Naricual formations of Oligocene age constitute the reservoirs. Thickness of these intervals is 793-854 m with 366 m of net oil sandstone. The depth of the Naricual reservoirs is around 4,116 m, with average porosity of 15%, permeability of 500 md, and water saturation of 20%. A 2,000-m-thick sequence of Oligocene-Miocene shales constitutes an effective regional seal. The main reservoirs correspond to the Naricual Formation which yields a high average rate of production per well
