Probabilistic Seismic Inversion -  Mar.8,9,11,12 (half days)-  Pat Connolly

Canadian Society of Exploration Geophysicists (CSEG)

AbstractResults from any seismic inversion are inherently uncertain. Uncertainty arises from the difficulty in compensating for the missing low frequencies, the variability of the relationships between reservoir and elastic properties, errors in the seismic amplitudes and so on. Deterministic inversions may, in some situations, be accurate enough for their intended purpose, but often they will contain significant biases that can be hard to detect and which will render the results unreliable.A process that can provide estimates of the probability of results allows for an assessment of their value and is hence fundamentally more useful. Bayes theorem provides the framework for such a process. However, while the theorem itself may be considered straightforward, adapting it to the specifics of seismic inversion is anything but.The first proposals for Bayesian inversion schemes appeared in the late nineties but it is only in recent years that commercial applications have become available. During this time Bayesian experts have been acquiring a deeper knowledge of geophysics and geophysicists a deeper understanding of Bayes theorem resulting in a new fusion of ideas and new applications that have the potential to provide consistently reliable results.In this 4- half day course I will summarise the challenges of seismic inversion, explain the principles of Bayes theorem and describe the various ways it can be adapted for real-world problems. I’ll show how the various Bayesian algorithms deal with the specifics of seismic inversion for facies probabilities and describe the adaptions required by geophysics to ensure, for example, that the final result is a stable image.This is an intermediate level course for participants with experience of seismic interpretation and analysis. Prior knowledge of probabilistic methods is not required. Excel-based exercises will be provided and a full set of PDF handouts.
