Iterative separation of blended marine data: Discussion on the coherence-pass filter

n conventional marine acquisition surveys the time intervals between the firing of successive sources are large enough to avoid interference in time. To obtain an efficient survey, the spatial source sampling is therefore often (too) large. How- ever, much attention has been drawn recently to blended ac- quisition designs, where sources are shot...

Separation of blended data by iterative estimation and subtraction of interference noise

Conventional data acquisition practice dictates the existence of sufficient time intervals between the firing of successive sources in the field. However, much attention has been drawn recently to the possibility of shooting in an overlapping fash- ion. Numerous publications have addressed the issue from dif- ferent scopes (denoising,...

Separation of blended impulsive sources using an iterative estimation-subtraction algorithm

Traditional data acquisition practice dictates the existence of sufficient time intervals between the firing of sequential impulsive sources in the field. However, much attention has been drawn recently to the possibility of shooting in an overlapping fashion. Numerous publications have addressed the issue from different scopes (de-noising,...

An r-based overview of the WRW concept

The WRW model serves the geoscientists’ community as a global language dedicated to deliver a better insight into the seismic reflection experiment. In today’s numerical modeling, wave equation-based techniques such as implemented in the WRW model are used more and more, while it becomes clear that ray tracing methods do not have the required...
