The drillship Deepsea Metro-1 drilled Sunbird-1 in 723 m (2,372 ft) of water in offshore area L10A, and to a final depth of 2,850 m (9,350 ft) below the drill floor.
The well penetrated the top of the Sunbird Miocene pinnacle reef at 1,583.7 m (5,196 ft) subsea, intersecting a hydrocarbon column. However, the vertical extent of the column remains unclear due to difficulties assessing wireline logs in the upper section of the reef, with extensive losses of drilling fluid into porous and permeable parts of the reservoir.
Recovered hydrocarbon samples will undergo geochemical and other analyses.
BG says it is unclear at this stage whether the find is commercial. Sunbird-1 will be P&A’d.
