Abstract

Klokov, A., Irkabaev, D., Ogiesoba, O., Skachek, K. and Munasypov, N., 2014. Diffraction analysis for the Sortym Formation using vertical seismic profiling data. Journal of Seismic Exploration, 23: 463-480. Seismic diffraction analysis may be a strong supplement for interpretation workflows. It allows characterization of small geologic features, which may not be detectable by conventional attribute analysis. Diffractions can play a significant role in fracture detection and characterization. In this work, we extract seismic diffractions from vertical seismic profiling (VSP) data acquired within the Sortym Formation in West Siberia. Seismic images of scattering objects were constructed for three components of the wavefield. We interpret the multicomponent diffraction images, comparing them with instantaneous frequency and instantaneous amplitude derived from conventional migrated data. The diffraction analysis allowed us to refine composition of the strata, to detect fracture clusters, and to predict the cluster orientation.
