WesternGeco
completes first Q-Marine survey in Danish sector of North Sea
Posted: 08 June 2004
WesternGeco announced today that it
has completed acquisition of a Q-Marine* seismic survey for the
Danish Oil and Natural Gas Company (DONG) over the Siri field in
the North Sea.
The 128-square-kilometer, high-resolution Q survey was acquired
in May over a 1996 heritage survey and will include 4D processing
of the vintage data.
"WesternGeco Q-Technology was selected for this monitor survey
because of the high activity level in the area where the increased
spatial Q-marine sampling could enhance noise reduction, “ said
Jesper Wissendorf Hansen, operations geophysicist, DONG E&P
A/S. “Furthermore, the steerable streamers added a safety
element to the work around the installations in the area, in addition
to the advantage of steering the feather.”
The survey was conducted in two phases. First, the Q-Technology*
vessel Western Pride, towing six 3200-meter cables with 100-meter
separation, repeated the 1996 survey. An interleaved pass then
increased data density and will be used for enhanced imaging.
“We are pleased that DONG has chosen WesternGeco Q-Technology
for the repeat survey of this reservoir,” said Roar Bekker,
manager, WesternGeco Europe. "The high repeatability and superior
resolution of the Q survey will enable improved knowledge of the
Siri field.”
