A processed seismic record that contains traces that have been added together from different records to reduce noise and improve overall data quality. The number of traces that have been added together during stacking is called the fold.

Sep 17, 2014 · Stacking compresses the data volume in the offset direction and yields the plane of stacked section (the frontal face of the prism). Migration then moves dipping events to their true subsurface positions and collapses diffractions, and thus increases lateral resolution.

Apr 24, 2018 · Seismic inversion, most of the time used in oil and gas industry, is the process used to reconstruct earth properties. It combines seismic and well data to predict rock properties (lithology, fluid content, porosity) across a survey. These rock properties can be used to identify hydrocarbon and reservoir.

Correlating seismic with well log data • Drilling a well provides “ground truth” to a seismic interpretation • Borehole provides velocities for depth migration

Stacking combines a collection of noisy seismic gathers, such as NMO‐corrected CMP gathers or migrated gathers, into a single less noisy seismic section. Existing techniques stack each gather independently, and in the process, ignore the tremendous structure of seismic signals.

Stacking plays an important role in improving signal-to-noise ratio and imaging quality of seismic data. However, for low-fold-coverage seismic profiles, the result of conventional stacking is not always satisfactory.

5 days ago · The diverse spectrum of signals that emerge from the seismic data typically only appear in gravimeter data. However, unlike gravimeter measurements, our global seismic stack provides a much broader spatial and continuous temporal resolution, offering enhanced insights into the sources of these signals.

5 days ago · The present study deals with improving the seismic data quality to better interpret the subsurface structure of the Heba Oil Field using post-stack seismic data processing. Potential hydrocarbon accumulations have been discovered in the study area as deep as the Cretaceous Bahariya reservoirs. The seismic data used for these discoveries was processed mainly for this shallow section. The main ...

This letter presents a modified Capon beamforming algorithm, called Capon stacking, to improve the vertical (temporal or depth) resolution of seismic stacked images.

Pre-stack seismic data retain the amplitude variation with offset (AVO) characteristics, providing more geophysical information reflecting lateral reservoir variations, thus facilitating the identification of oil and gas reservoirs. However, due to the band-limited nature of seismic data, the precision of forward modeling, and the accuracy of algorithms, traditional pre-stack approaches suffer ...
