Maurel & Prom Announces Discovery of a New Reservoir at Kissenda in Gabon

Sunday, November 22, 2009

The Onal 1002 well has reached a vertical depth of 1,195 metres. The well encountered 82 metres of hydrocarbon-impregnated reservoirs in the Kissenda Sandstone. Selective tests at a depth of 41 metres have given a cumulative oil flow rate of 1,300 bpd. The extent of these results was unexpected.

The discovery of oil reservoirs in the Kissenda formation in the South-East of Onal and the test results obtained on OMOC-1 in March 2009 (1,130 bpd in the two formations) indicate a strong probability of extension of the reservoirs between these two zones.

The importance of this discovery, the majority of it situated in the Onal operating permit, will depend on the level of the water surface at Kissenda and the thickness of the impregnated reservoirs.

These two uncertainties will be lifted after the drilling of a well by Caroil 9, once the platform is built. Production from the Onal-1002 well could replace the production expected from the Omko 301 well, which has shown disappointing results.

Failure of well OMSN-1
The OMSN-1 well has encountered non-mobile hydrocarbons indications. The drilling of this well confirms that oil was indeed generated in this section of the Omoueyi license (M&P 100%). An additional seismic survey has been initiated to locate, ahead of the well, any potential oil traps for the oil that presence has been proved by the previous wells.

Update on current projects

Mafia - Tanzanie
Drilling has encountered technical problems that are not serious but given the depth and temperature have created long delays at each maneuver. If there are no further incidents, the first test results are expected by the end of the month.

Draco - Syrie
Drilling has reached a depth of 2,962m (in the Trias). The target is 3,600/3,900m.

Cascabel - Colombie
The well has reached a depth of 2,915m. The target is 5,100m (early February 2010), common depth in
this region. The results are perfectly in line with predictions.

Tiétié - Congo
This well has been held back but should start before the end of the month.

M’Bafou - Congo offshore
The rig will be in place before the end of November.

N’Goumba - Congo
The start of the drilling is depending of the weather conditions. It is expected for mid-December.

Gwedidi - Gabon
The drilling of the well is expected to start on 23 November.
