West Katakolo field as a key case

• The field was discovered in 1981. The producing layers are the Eocene-Upper

and Lower Cretaceous carbonates of a paleostructure, unconformably covered

by Plio-pleistocene clastic sediments. Estimated resources in place: 28-30

million bbl of oil and > 40 bcf of gas.

• West Katakolon oil field has been proven by 3 wells: WK-1 , WK-1A and WK-2

(1981-1982)

• Different production performance had been recorded:

• In WK-1a gas flowed from two layers in the Gas Cap with flow rates up to

11MMSCFD from each zone.

• In WK-2 oil flowed from two zones with flow rates between 1000-1400

bbl/day each.

West Katakolo Field: E&P Program and Main Issues to be solved

West Katakolo field reservoir rocks

Work to be done:

Potential reservoir rocks mapping - done

Potential reservoir rocks sampling OK

Potential reservoir rocks has been analyzed (porosity, permeability)

Reservoir Studies - Reservoir sampling of potential reservoir analogues

Rocks has been analyzed in terms of porosity and permeability properties, whereas oil has been analyzed in terms of geochemical properties, provenance and migration.

Potential reservoir rocks sampling Eocene limestones samples impregnated with oil
