Abstract
Summary
This work shows a revisited multiple attenuation workflow applied over a selection of the Minagish dataset. Essential components of this workflow are extended interbed multiple prediction (XIMP), simultaneous matching between the field dataset and predicted multiple models, and improved quantitative well-constrained quality control (QC) of the final results. The XIMP and the adaptive subtraction framework allow the application of the multiple attenuation workflow before imaging, avoiding the crosstalk between primaries and internal multiples during the migration process. Noticeable improvements can be seen over the Cretaceous and Jurassic zones on pre-stack gathers, seismic stacked sections, and well ties.
