Abstract
Summary
Accurate low frequency background models are essential for pre-stack inversions. We compare horizon based to image-guided interpolations’ ability to build low frequency background models. We show that image-guided interpolation produces either comparable or improved low frequency models compared with horizon based interpolation while saving a significant cost. This is demonstrated through a few examples which show horizon based interpolation depends heavily upon having accurately picked horizons. If all the necessary horizons are not picked, horizon based interpolation will produce a non-geological background model which will impact the absolute inversion results.
