- W2896883268 abstract "Summary Prestack scaling is an essential step which is used to correct the amplitudes of seismic reflection data as part of quantitative interpretation workflows such that they honour the background AVO behaviour. The resulting scalers are fed into prestack seismic inversion algorithms to yield better results. Prestack scaling analysis is often performed in the reflectivity domain, however, we propose an algorithm to optimise these scalers further by defining an optimisation engine based on minimising the misfit between measured and inverted acoustic and shear impedances along selected wells. Also, we add constraints to avoid unstable solutions due to possible local minima. In this paper, we show two examples of this algorithm; a synthetic example which shows how the technique should work and a real dataset example where we compare the inversion results before and after amplitude scaling optimisation." @default.
