The objective of this paper is to assess features of broadband processing of 3D seismic data, acquired with variable depth streamer in «hard» bottom conditions within Barents Sea shelf. The evaluation of processing sequence for maximum signal preservation with a minimum artefacts introduction is shown. The main attention is paid to such procedures as linear noise attenuation, multiple suppression using MWD and SRME technics, receiver side deghosting. Based on the proposed processing sequence, the reprocessing results of retrospective 2D seismic data with significant quality improvement of the final sections are presented.......

The features of the mechanical and acoustic caliper data, the main approaches to their preprocessing in the «Sonata» program are described. A method has been created for correcting measurement results for eccentricity of the device. Determining the position of the center of the device is carried out by minimizing the functional using the Lagrange multipliers method. The methods of noise reduction in the acoustic caliper data are considered. For the program «Sonata» developed a method of noise suppression, based on the method of principal components.......

A strong effect of sediments compaction was identified in the poor consolidated gas bearing reservoir in Turonian formation (West Siberia region, Russian Federation). New depth depended technique of elastic properties analysis (feasibility study), lithologyand formation properties prediction in case of low consolidated formation was suggested.......

In this article some interpretative problems of classical Laterolog 3 (LL3) tool have been considered. These problems are mainly related with the focusing, the location of the remote electrodes, the Delaware and Groningen effects and the tool’s asymmetry. Possible constructive solutions of the problems are presented. The material is illustrated with the results of numerical experiments and borehole surveys. The borehole surveys were carried out with the LL3 tool and the high resolution various investigation depth MAGIS-5BK tool.......
