FORMATIONS

SOURCE ROCK

The existence of an effective source rock can be proved by the presence

of oil throughout the majority of the structures in the Oriente Basin.

Marine shales and limestones from the Cretaceous Napo formation are

the primary source rocks.

RESERVOIR ROCK

The Hollin and Napo formations contain the main reservoirs for the

Oriente Basin

Formation Porosity (%) Permeability (mD) Thickness (ft)

Hollín 12-19 10-250 100-300

Napo T 8-18 10-450 > 80

Napo U 10-22 30-850 > 50

Basal Tena 5-12 20-200 ~ 30

The Oriente basin is one of the most prolific petroleum systems in South America

REGIONAL GEOLOGY

13

SEAL ROCK

The primary seal rock of the Oriente basin is composed of fine-grained and

very fine sediments (shale and clay):

Clays and siltstones in the Basal Tena sands reservoir

Upper Napo shales in the “U” sands reservoir

Middle Napo shales in the “T” sands reservoir

Lower Napo shales in the “Hollin” sands reservoir

FORMATIONS

The Oriente basin is one of the most prolific petroleum systems in South America

REGIONAL GEOLOGY

GEOLOGICAL TRAPS

1. Structural Traps: Associated to anticlines caused by inverted faults

with north to south trend formed at Late Cretaceous, Eocene, Miocene

and Pliocene.

2. Stratigraphic Traps: Associated to the sand reservoirs from the

Cretaceous Napo and Hollin formations.

TIMING

The petroleum system had essential elements and processes to allow

the generation, migration and accumulation of hydrocarbons for the Oriente

basin
