Abstract

The use of several simultaneously operating sources in seismic explorations allows one to obtain large amounts of data per unit of time than for classical works with a single source, and also to create such acquisition configuration that would not be feasible for economic reasons in the traditional approach to work with a single source. This technology is known as multisource (simultaneous source) acquisition. The main goal in working with a multisource is deblending. Different methods of separating signals use features of a complex wavefield obtained by the operation of a multisource. In this paper, we propose a method of hyperbolic median filtering using the kinematic properties of reflected waves. The use of this method makes it possible to obtain separated signals as a result of solving the noise suppression problem. The operation of this algorithm is demonstrated by the example of source configuration for marine seismic exploration, which allows virtually increasing the length of the recording streamers and reducing the step between excitation points.
