Schlumberger has acquired Staag Imaging, a Houston-based provider of depth-imaging technologies for seismic data processing, for an undisclosed fee. Staag will become part of the Schlumberger WesternGeco business unit.
According to Schlumberger, Staag is one of the first providers of a commercial Full Waveform Inversion (FWI) technique, which promises to change the building of earth velocity models.
Staag’s FWI is an automatic, data-driven tool that uses the two-way wave equation method to build velocity models of the subsurface, including complex geology formations such as salt bodies. This FWI technology can automate a large part of the velocity model-building workflow. The models it produces can then be used to exploit the power of WesternGeco’s high-resolution Reverse Time Migration capability.
‘Our customers’ need for rapid, but accurate, imaging of complex subsurface geology is increasing dramatically,’ said Ginger Hildebrand, vice-president, seismic data processing, WesternGeco.
He added: ‘The combination of Staag’s FWI with our full complement of existing algorithms will allow us to accelerate the delivery of superior images of even the most complex subsurface structures.
‘This capability will unlock the full potential of our newest coil and wide-azimuth acquisition configurations, as well as enhance the value of our extensive multiclient library.’
