The appraisal well was spudded in June 2008 and the hydrocarbons were encountered in formations of lower carboniferous age. StatoilHydro and its project partner, Algerian state-owned company Sonatrach, are reportedly satisfied with the results of the well.

The recently completed Tinerkouk-2 well is the sixth positive well in the license drilled by StatoilHydro. The Norwegian company is currently drilling the TGN-1 well, an exploration well also situated in the southern part of the Hassi Mouina license.

StatoilHydro has a 75% interest in Hassi Mouina, while its partner Sonatrach has a 25% interest.
