摘要： A system and method for attenuating noise in seismic data representative of a subsurface region of interest including receiving a seismic dataset representative of seismic signal or seismic noise and a seismic dataset representative of seismic signal and noise, transforming them into a domain were they have sparse or compressible representation, comparing the sets of coefficients to identify desirable coefficients in the set of coefficients representing the signal and noise dataset, selecting the desirable coefficients to produce an improved set of coefficients, and inverse transforming the improved set of coefficients to produce a modified seismic dataset. The modified seismic dataset may be noise-attenuated seismic data or may be a noise model that is subtracted from the original data to produce noise-attenuated data.

摘要： Systems and methods for estimating reservoir productivity as a function of position in a subsurface volume of interest are disclosed. Exemplary implementations may: obtain an initial depth uncertainty model; obtain training depth uncertainty parameter values from the non-transient storage medium; obtain corresponding training depth uncertainty values; generate a trained depth uncertainty model by training the initial depth uncertainty model using the training depth uncertainty parameter values and the corresponding training depth uncertainty values; and store the trained depth uncertainty model.

摘要： A system and method for determining a 4D difference from 4D seismic data including receiving a baseline seismic dataset and a monitor seismic dataset; identifying a 4D signal present in the monitor seismic dataset to create a 4D monitor dataset and a signal in the baseline seismic dataset which matches the monitor seismic dataset to create a baseline matching signal dataset; differencing the baseline matching signal dataset and the baseline seismic dataset to create a 4D baseline dataset; and differencing the 4D baseline dataset and the 4D monitor dataset to create a 4D difference dataset. In an embodiment, a multi-scale, multi-directional transform is used to identify the 4D signal present in the monitor seismic dataset and the signal in the baseline seismic dataset which matches the monitor seismic dataset.

摘要： A system and method for processing a prestack seismic dataset with at least one smoothly varying (redundant) axis including transposing the prestack seismic dataset, slicing the prestack seismic dataset into depth or time slices with at least one redundant axis, processing the slices, and transposing the slices to create a processed seismic dataset. The redundant axis may be representative of offset, angle, azimuth, or time between time-lapse surveys. The processing may include filtering the slices to attenuate coherent or incoherent noise.

摘要： Geophysical data representing at least first and second overlapping geophysical spaces may be aggregated. A first set of geophysical data representing the first geophysical space and a second set of geophysical data representing the second geophysical space may be obtained. The second set of geophysical data may be separate and discrete from the first set of geophysical data. The first set of geophysical data may be transformed from a first parametric domain to a third parametric domain, while the second set of geophysical data may be transformed from a second parametric domain to the third parametric domain. The first set of geophysical data may be fused with the second set of geophysical data in the third parametric domain to create a fused set of geophysical data. The fused set of geophysical data may be transformed from the third parametric domain to a fourth parametric domain.
