Maurel & Prom reported that the Onal 1002 well has reached a vertical depth of 1,195 meters. The well has encountered 82 meters of hydrocarbon-impregnated reservoirs in the Kissenda Sandstone. Selective tests at a depth of 41 meters 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 results of test 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.
