Marathon Oil Corporation has discovered that the pre-salt Diaman-1B exploration well offshore Gabon has encountered 160-180 net feet of hydrocarbon pay in the deepwater pre-salt play. Preliminary analysis suggests that the hydrocarbons are natural gas with condensate content, pending results of ongoing analyses of well data.
The Diaman-1B well was drilled to a total depth of 18,323 feet in approximately 5,673 feet of water in the Diaba License G4-223.
The Diaman-1B successfully confirms the existence of a working petroleum system and is the first discovery drilled in the deepwater portion of the pre-salt play. Diaman-1B is located over 60 miles away from the nearest other pre-salt commercial discovery.
