Shot-based deghosting for variable sea surface and receiver depth

Jan-Willem Vrolijk, Gerrit Blacquière

Research output: Chapter in Book/Conference proceedings/Edited volumeConference contributionScientificpeer-review


Uncertainties in the water velocity, receiver location and sea surface state introduce noise and ringing after deghosting. Therefore, a shot-based deghosting method is discussed that includes a constraint to reduce this effect of inaccuracies in the ghost model. First, we show results for a flat cable with an accurate ghost model. After that, the deghosting method is applied to a shot with a slanted cable. Finally, an inaccurate ghost model is applied to a shot, that is modelled with a variable sea surface.
