In this phase of processing, the minimum-phase component should be removed to yield a seismic section made up of symmetric wavelets. The symmetric wavelet is better suited for …

Jun 11, 2025 · Phase rotation is a critical step in seismic data interpretation, enabling the accurate identification of subsurface structures and reservoirs. Advanced phase rotation techniques …

Oct 1, 2014 · We will look at how to manipulate the phase of a seismic trace by manipulating the phase of its Fourier transform and will use that idea to generate the well-known instantaneous …

In summary, 90 degree phase rotation technology can effectively improve the recognition ability of seismic attributes to thin sand body. For the prediction to thin reservoir, making 90 degree …

Nov 29, 2024 · This article is a practical guide to leveraging common seismic attributes for enhanced geological interpretation, more specifically, how to make the best out of paraphase …

Recognizing seismic phase as a primary attribute in seismic processing workflows, we apply circular statistics, a robust data-driven approach for correcting phase distortions in prestack …

The program estimates the phase rotation angle by comparing bandpass filtered impedance logs with the shaped seismic data assuming that well ties are reasonably good.

We discuss the recently introduced phase decomposition analysis, which entails amplitude variation with time as a function of the seismic reflection phase.

Phase rotation refers to rotation of the complex-trace vector. Phase rotation for a specified phase angle is done as follows: A rotation of 90° (π /2 radians) transforms the complex trace, as …

Seismic data can be indicators of many factors such as amplitude, continuity, phase, and polarity of the reflections coming from the subsurface. This article reviews how the last two are used in …
