Maurel & Prom Abandon's Doungou-1 Exploration Well

Maurel & Prom's Doungou-1 exploration well on the La Noumbi permit, whose main objective was the Vandji sandstone recervoir, was plugged and abandoned.

The well was the first to be drilled by the La Noumbi Joint Venture, comprising Maurel & Prom (operator and 49% working interest), Burren (37% working interest) and Afren (14% working interest).

The Doungou well was spudded on 13th August 2007 and reached a total Depth of 2,602m (2,168 tvdss) on 26th September 2007.

Oil and gas shows were observed in several intervals in pre-salt formations. A comprehensive logging suite, including pressure tests and sampling data, was acquired across the intervals of interest. Reservoir quality is poor, due to low permeability and the well was plugged and abandoned.

The well proves the existence of a working hydrocarbon system at several levels in an under explored part of Congo Brazzaville, which is encouraging for future exploration activity.

A new 2D seismic data set was recently acquired in the north of the La Noumbi license covering 200 kilometers in the area adjacent to the Tie Tie oil discovery. Together with the new data acquired in 2006 and the reprocessed existing data, these will be interpreted with the benefit of the Doungou well results to determine new prospects to be drilled in 2008.
