PARIS, January 5, 2011 /PRNewswire/ -- NIGERIA

In Nigeria, operated production levels (oil + condensate) varied between 15,000 boepd and 30,000 boepd (with 20.25% attributable to Maurel & Prom) during the fourth quarter of 2010. This fluctuation was due to technical issues linked to production starting up again after the fields had been shut down for 15 months.

Two lifting took place during the fourth quarter of 2010 for a total of 1.1 million barrels for the SEPLAT share (with 45% attributable to Maurel & Prom).

Gas production is currently 95 million cubic feet per day. The purchase price is rising and should reach the international prices end of 2012. The immediate production capacity of the fields is 40% greater than current level; production being temporarily limited because of maintenance work in progress on the electric plant supplied.


ONAL AEE (operator, 85%)

Maurel & Prom is announcing the positive result of the OMOC-N-501 and OMOC-103 delineation wells in the Onal AEE.

The wells have shown a height respectively impregnated with oil of 32 m on OMOC-103 m and 9 m on OMOC-N-501.

The drilling of these wells, targeting the Kissenda Sandstone (Gres du Kissenda), is part of the OMOC-North field delineation programme which, in addition to the discovery well (OMOC-N-101), included plans to drill six appraisal wells (OMOC-N-201, OMOC-N-301, OMOC-N-302, OMOC-103, OMOC-N-501 and OMOC-N-601).

The findings from these wells confirm that the reserves extend into the Kissenda on this part of the field where the production of the wells should be 500 boepd in average.

The predominantly Gres de Base wells (OMOC-N-301 and OMOC-N-302) were connected up to the oil pipeline serving the Onal platforms (in blue) on 15 December 2010.

The predominantly Kissenda wells which have already been drilled and the future OMOC-N-601 well - to be drilled during the first quarter of 2011 - will be connected up to the production centre via a new pipeline, which is going to start to be laid (in red on the map).

Alongside this, the Group is assessing the OMOC field discovered in March 2009 with the OMOC-101 well to the south of ONAL. With this in mind, the OMOC-102 well and the drilling of the OMOC-201 well will resume during the first quarter of 2011.

Following this work, the wells will be connected up to the OMOC-North pumping facilities from the second quarter of 2011.

On 17 December 2010, exclusive development authorisation obtained for the Gwedidi (OMGW) and M'Bigou (OMBG) fields

Maurel & Prom owns 100% of the interests in these two fields, on which the company Tulipe Oil has a 15% back-in right, which would take Maurel & Prom's interest down to 85%.

Group production in Gabon

The Group's production in Gabon, which peaked at 20,198 boepd on 31 December 2010, was affected during the fourth quarter of 2010 by more maintenance work being carried out than planned on the pumps for wells in the Onal field, as well as water injection starting up on the Omko field, work carried out to optimise surface facilities on the Gwedidi field and the connecting up of the two OMOC-N-301 and OMOC-N-302 wells.

As a result, the level of production in Gabon averaged out at 16,900 boepd for the fourth quarter of 2010.
