Abstract:
1. A method for simulating up-going pressure wavefield data, comprising: receiving pressure data from pressure sensors disposed on a first streamer and a second streamer of an over/under streamer pair; receiving velocity data from velocity sensors disposed on the second streamer; creating simulated pressure data that would have been acquired by a simulated single streamer disposed at a depth equal to a vertical distance between the first streamer and the second streamer and that would have been acquired in a calm sea having a flat surface, wherein the simulated pressure data is created based on the pressure data; creating simulated velocity data that would have been acquired by the simulated single streamer based on the pressure data from the pressure sensors disposed on the first streamer and the velocity data from the velocity sensors disposed on the second streamer; and combining the simulated pressure data with the simulated velocity data to estimate the up-going pressure wavefield data.
