Schlumberger Launches Breakthrough Marine Seismic Technology
New IsoMetrix service delivers the first true 3D wavefield measurement
Schlumberger today announces the launch of IsoMetrix* marine isometric
seismic technology and the IsoMetrix family of marine seismic products.
This breakthrough technology outputs isometrically sampled
point-receiver data in both crossline and inline directions?capturing
the returning wavefield in three dimensions and providing the most
accurate images of the subsurface ever recorded.
The IsoMetrix system uses calibrated, multisensor MEMS technology that
forms part of the new WesternGeco Nessie-6* point-receiver seismic
streamer. The sensors measure acoustic pressure as well as vertical and
crossline acceleration throughout the frequency range, and these
measurements are provided as customer deliverables.
'Through an extensive 10-year research and engineering program, we have
developed a new category of seismic that not only includes the
acquisition technology, but also the algorithms and workflows needed to
manage such an unprecedented amount of data,? said Carel Hooykaas,
president, WesternGeco. 'The step change in imaging is as profound as
was the move from X-rays to full 3D scans in the world of medicine.?
IsoMetrix technology enables efficient exploration, high-resolution
near-surface characterization, well integrity planning and unmatched 4D
repeatability. The technology is compatible with other WesternGeco
services such as the Coil Shooting* and Dual Coil Shooting* acquisition
techniques. Field trials last year proved the technology′s high
accuracy, achieving a 12:1 crossline reconstruction ratio and producing
a 6.25-m data grid from streamers 75 m apart.
A new range of applications is now being developed based on IsoMetrix
technology to address currently intractable exploration and development
challenges while simultaneously improving productivity.
