Improvement of seismic image in interpretation stage for the purposes of seismic facies analysis

This review relates to an improvement of seismic image in interpretation stage for the purposes of seismic facies analysis. The paper presents in detail the theoretical aspects of vertical and horizontal resolution of seismic data. The authors analyse two technological approaches. The first approach is related to application of feasible wavefield post-processing tools. The paper contains an overview of efficiency of frequency-dependent attribute use, in particular, frequency decomposition of wavefield. The second approach is about an “additional graphical processing” of images, data visualization, and their feasible transformation using tools for direct processing of static images. To illustrate certain provisions and conclusions, the authors concentrate on sedimentary objects, such as paleochannels; the studies of them face limitations caused by resolution of the seismic method. The paper also presents the case study of integrated seismic data interpretation for the Tyumen paleo riverbed system investigations by the example of one field in the Khanty-Mansi Autonomous Okrug. Integration of the approaches of amplitude interpretation of seismic data allows identifying and mapping a network of paleo riverbeds within the study area as well as parametrization of the object with further prediction of riverbed deposit thickness
