“…This system consists of five permanently installed seabed cables in the southern fault block (Panel 4) of the field and is supplemented with surface towed streamer data (Cooper et al 1999c). A base line survey over Panel 4 was acquired before production in 1995 and repeated in 1998 after ten months of production.…”

The Foinaven Field was discovered in 1992 and is estimated to hold up to one billion barrels of oil, with the current development expecting to recover 250 million barrels. BP Amoco is the operator of the field, holding a 72% interest with Shell UK as partner. The Foinaven structure is a faulted anticline and the trapping mechanism has elements of stratigraphic pinch-out, fault and dip closure. The field is divided into five fault/stratigraphical segments with varying oil-water and gas-oil contacts. The reservoir is Paleocene in age and comprises channelized, silici-clastic turbidites, with three main oil-containing sandstone intervals. Reservoir rock varies in character from thinly interbedded sandstones to massive channel sandstone. The reservoir is good quality, fine to medium grained, with 20-
