 W-16: Inversion-Based High-Resolution Imaging of ReservoirsSEG 2012 Annual Meeting Technical Program DescriptionSeismic processing, and what we now more broadly call seismic imaging, have historically been accomplished by applying adjoint operators. Under simple circumstances this approach provides satisfactory results. When the overburden is complex, when scattering from the target is not simple (e.g. multipathed or multiply scattered), when the acquisition geometry is irregular, or when the waveforms are not spectrally balanced, adjoint operators often do not provide images of sufficient quality. These may be manifest as artifacts in the image, loss of resolution, acquisition footprint, and incomplete signature removal. In principle, we can use inversion to correct for these effects. Doing so can lead to higher resolution, artifact-reduced, proper amplitude calibrated and spectrally balanced images. Obtaining the benefits of the inversion-based approach to imaging can be challenging however. We are limited by our knowledge and choices of the physics we use in forward modeling operators; we are limited by the amount of distortion caused by illumination, complex scattering, and spectral distortions that are observed in difficult imaging situations. We are not without hope however; witness the recent revolution in full waveform inversion for estimating velocity models. This workshop provides a venue to discuss recent advances in inversion-based imaging of all forms, from acquisition through processing and imaging. We also hope to describe the likely way forward to improve seismic imaging through inversion. What physics should we use? What are the limits of our approaches? Is inversion-based imaging allowing us to image targets we could not image before? What changes to acquisition might be beneficial? The workshop will consist of a series of invited presentations on the current state of inversion-based imaging, and likely future advances to set the stage for audience questions and an audience/panel discussion.
