High-resolution imaging of subsurface structures for the creation of accurate 3D geologic models and reliable inversion to reveal indicators of rock properties requires bandwidth-enhanced seismic data as input, not only in a temporal sense but also spatially. The benefits of spatial bandwidth enhancement have not been widely documented for marine seismic acquisition because operational and technical constraints have, until recently, proved prohibitive to a towed-streamer solution. A new technology has now been introduced that is able to address both the temporal and spatial bandwidth constraints in a joint interpolation and deghosting method, enabling full 3D processing capabilities that go well beyond what is traditionally understood under broadband. The benefits of the new technology include improved 4D analysis, effective seismic interference removal, and enhanced imaging and inversion.
