24-07-08 The exploration well OMKO-1, formerly named Alonha-C and located at 6 km East of the Onal field (3.6 km East of the production centre), has been drilled at a 1,800 m depth. The OMKO-1 well met two oiled sandstone intervals in the following geological formations:
-- The Kissenda over 56 m, a new subject in this area of Gabon. This level reached an eruptive production of 3,050 bpd on a 40/64 inch choke with a 595 psi head pressure.
-- The Base Sandstone over 43.5 m, a topic that Maurel & Prom has already highlighted in Congo with the M’Boundi and Kouakouala fields and in Gabon with the Onal field. This level reached an eruptive production of 2,460 bpd on a 32/64 inch choke with a 660 psi head pressure. In both cases, the oil is between 35.7 and 36.7 degrees API.

This oil discovery in Gabon by Maurel & Prom validates the exploration subjects in the sedimentary basin in the North-East area of the Onal field. This well will be immediately followed by the exploration well OMBG (ex Alonha B). Other exploration wells are scheduled in this area, and amongst them Alonha A, Onal East and Maroc.
Simultaneously, the drilling of the exploration well N’Zamo will be resumed in order to study the South-West area of the field.

Depending on rigs availability, Maurel & Prom will undertake the appreciation of this discovery by the end of the year. Maurel & Prom, operator, owns 100 % of the exploration permit Omoueyi, signed on September 27, 2005, with the Gabonese State. The Gabonese State has right of return of 15 %.
