Block 192 Summary

192

The two main reservoirs are Vivian Formation and Chonta Basal Sand Member:

• Structural traps with lateral stratigraphic variations and early structural evolution

• 85% Production & Reserves: Vivian Reservoir.

• Vivian: Poros 14-21%; Permeab 20-5000md, Chonta: Poros 12-19%; Permeab 5-1000md.

• Vivian: strong water drive

• Almost al reservoirs are filled to the spill point.

The Block 192 shows three oil

families, from light oil (25°to 35°

API), medium oil (18° to 25° API),

and heavy oil (10° to 18° API).

The traps are anticlines structures

of low relief, axes mainly oriented

NE-SW and N-S. The structural

closures varies from 4 to 20ms.

Stratigraphic Play in Tambo & Ceci Area

Stratigraphic Play:

Seismic Anomalies

Type “Patch Reef”

Tambo area is located in the SW

border of Block 192. Using the 3D

seismic data from the Tambo area

it was possible to detect seismic

amplitude anomalies which could

represent a new stratigraphic play

concept in the Maranon Basin.
