HOUSTON, July 21 -- Harvest Natural Resources Inc., Houston, has discovered a second oil accumulation at its Gamba presalt oil discovery off Gabon.
Log evaluation, pressure data, and a fluid sample indicate the discovery of 35 ft of oil pay in the Middle Dentale secondary objective at the Dussafu Ruche Marin-1 well on the Dussafu Marin PSC. Harvest operates the block with 66.667% interest.
The well went to 11,355 ft true vertical depth subsea in 380 ft of water.
Harvest has appraised the Gamba discovery by drilling a sidetrack ¾-mile southwest to test the lateral extent and structural elevation of the Gamba reservoir. The sidetrack was drilled to a TD in the Upper Dentale of 11,562 ft, 9,428 ft TVD ss, and found 19 ft of oil pay in the Gamba reservoir.
Harvest will now sidetrack the DRM-1 well to the northwest of the original DRM-1 wellbore to further appraise the extent and structural elevation of the Gamba and the commerciality of the Ruche discovery.
