The Diaman-1B well, located over 96.5km away from the nearest pre-salt discovery, was drilled at a depth of 5,585 metres in approximately 1,730 metres of water in the Diaba Licence G4-223. Marathon Oil holds 21.25 per cent non-operated working interest in the licence.

The well discovery results reflected 49–55 net metres of hydrocarbons in the deepwater pre-salt play. Preliminary analysis revealed that the hydrocarbons found could be natural gas with condensate content.

According to the Texas based-energy company, the discovery confirms that a working petroleum system exists.

The operator Total and partners Marathon Oil, Cobalt International Energy and the government of Gabon are currently evaluating the well data.
