Reprocessing of reflection seismic data from the Skåne area, southern Sweden

Abstract: Seismic reflection surveying is a powerful method to explore the structures of the Earth’s crust and describe it is layers. It is also used extensively in the oil industry. Offshore seismic profiles were acquired in southern Sweden (Skane area) for petroleum exploration purposes, but no productive fields were discovered in that area. The seismic reflection data were collected and processed in the 1970s. The purpose of this thesis is to reprocess some of the seismic profiles from the 1970s with new processing programs to improve the results and compare it with the previous results. Offshore lines 208, 206, 212 have been selected in this project because they cross each other and are close to a borehole with sonic data. The borehole lies close to lines 208 and 212 as seen from the Skane area map. Also this report can be used to introduce the reader to fundamentals of seismic data processing. The processing was done using Claritas software by applying standard processing steps to produce migrated stacked sections for every line as a final product.
