RIO DE JANEIRO, Mar. 30 -- Eni SPA has let a contract to Petroleum Geo-Services ASA for a 1,500 sq km marine 3D seismic survey on a Santos basin block on which it has drilled three wells.
The survey of BM-S-4 Block will begin by June and take 45-50 days to complete. PGS shot a seismic survey over the block in 2000.
Last year, Eni reported that its 1-ENI-4A-RJS wildcat, drilled to 5,900 m TD in 387 m of water on the block, had gas shows. A well it drilled on the block in 2003 encountered oil but was plugged and abandoned (OGJ, Nov. 28, 2005, Newsletter).
