Broadband technologies of marine seismic survey: alternatives comparison

(Ampilov Iu.P. )

The article describes the main competitive technologies to obtain seismic record in a wide range of frequencies for shelf studies. These modifications of seismic exploration currently hold about half of the world market, while on the Russian shelf, they almost do not apply. The author analyzes the advantages and disadvantages of each method. It is concluded that multisensory technology application is preferable as compared with another solutions.......

New technologies for offshore acoustic profiling

(Tokarev M.Iu. Gainanov V.G. )

The new observation and data processing technologies for offshore acoustic profiling are proposed, which ensure essential reducing of the ghost reflection from water surface impact on the deep reflections, resolution and the noise immunity of survey improving, availability of the recorded data for estimation of sediments acoustic properties.......

Optimization of the processing flow of two-component 3 D seismic data, obtained in the shallow part of the Pechora sea

(Gorbachev S.V. Nurmukhamedov T.V. Nikulnikov A.Iu. )

The article describes the main features of the processing of OBC data obtained in the shallow part of the Pechora Sea. Seismic wave held is characterized as a complex picture with the presence of a large number of interferences of different nature. It is shown that the use of standard graph did not lead to a qualitative result. Adaptation of graph allowed to get additional benefits of the proposed sequence of procedures compared to standard processing.......
