Hydro
selects WesternGeco for North Sea Q-Marine Survey
Posted: 30 April 2004
Hydro awarded WesternGeco a contract to conduct acquisition and
processing of two 3D surveys over the Oseberg field, offshore Norway.
Using the Q-Marine* single-sensor marine seismic system, the 4D
project, scheduled to begin this month, repeats heritage surveys
over areas of approximately 906 and 191 square kilometers.
“We chose WesternGeco Q-Technology* for this important monitor
survey because of the advantages of active steering to best match
the source and receiver positions of the heritage surveys, and to
improve safety and enhance cost efficiency while working adjacent
to our platforms,” said Jens-Petter Kvarstein, geophysical
operations manager, Hydro. “We also expect the high-resolution
Q* survey to provide improved knowledge of the field for asset management
and reduced development risk.”
The Q-Technology vessel, Geco Topaz, towing six 3600-meter cables
with spreads of 750 meters and 500 meters, and utilizing the WesternGeco
proprietary calibrated Q-Marine source, will conduct the surveys.
“The high repeatability of Q-Marine surveys, coupled with
its superior resolution, makes Q the only true 4D Ready technology
for reservoir monitoring," said Roar Bekker, manager, WesternGeco
Europe. “Also, the Q-Marine active steering will reduce the
necessity of infill and provide better coverage around the three
platforms in the survey areas.”
Q is the WesternGeco proprietary suite of advanced seismic technologies
for enhanced reservoir location, description and management.
