Technical Paper: Broadband Seismic Methods for Towed-Streamer Acquisition

Abstract

One of the limiting factors in seismic resolution for marine towed-streamer acquisition is the ghost effect due to sources and receivers. The ghost is the reflection from the sea surface that interferes constructively or destructively with the primary reflections reducing the seismic bandwidth at the low end and the high end of the spectrum. Different acquisition and processing solutions were proposed during the years to address the ghost problem. In this paper we review these solutions and we introduce new slant streamertype acquisition with the processing based on prestack single-streamer deghosting.
