摘要： A method for processing seismic data. The method may include receiving seismic data due to a plurality of seismic sources and applying a first operator to the seismic data to generate a first estimate of seismic data. The method may then include applying a second operator to the first estimate of seismic data to generate residual seismic data due to one or more seismic sources. The method may determine a second estimate of seismic data based on the first estimate and the residual seismic data. The method may then process the second estimate of seismic data due to each seismic source to determine the presence of hydrocarbon deposits in a subterranean area of the earth.

The information handling system may receive seismic information from the DAS data collection system. The seismic information may include seismic traces associated with a plurality of depths in the wellbore. The information handling system may also generate a noise pilot trace by stacking one or more of the seismic traces, and subtract the noise pilot trace from the seismic information received from the DAS data collection system.

摘要： A method for processing microseismic data, comprises: receiving the microseismic data acquired by one or more multicomponent sensors; convolving the microseismic data with an operator that is applied to all of the components of the microseismic data; and applying a multicomponent filter operator to the convolved microseismic data. The microseismic data may result from human activity or be entirely natural. The filtering preserves the polarity of the received data whilst improving the signal-to-noise ratio of the filtered data.

摘要： A sensor assembly has first sensors spaced apart along a first direction, and second sensors oriented in a second direction generally orthogonal to the first direction. Differencing of outputs of the first sensors is performed, and differencing of outputs of the second sensors is performed. A signal output is produced by combining the differenced outputs of the first sensors and the differenced outputs of the second sensors, where the signal output represents a seismic response of a subterranean structure.

摘要： A method is disclosed for attenuating ground roll in seismic data signals. Seismic data signals are obtained from nearby seismic sensors. A difference filter is created that incorporates an estimate of ground roll differential move-out between the seismic sensors. The difference filter is then applied to the seismic data signals to produce a ground roll attenuated seismic data signal. The method can be used with one-pass and multiple-pass filter operations and can be used in connection with pairs of seismic data signals or with groups of seismic data signals from an areal pattern of nearby seismic sensors. The seismic data signals may be appropriately pre-processed and factors in addition to the ground roll differential move-out can be incorporated when creating the difference filter. The inventive method can be implemented in the time domain or in the frequency domain.

摘要： Coherent and incoherent noise in seismic signal data are attenuated by transforming the data using a diversity Radon transform from the first domain to a Radon-transform domain, wherein the transforming step further comprises the steps of:
(a) determining scaler data; (b) multiplying the data by the scaler data to produce scaled data; (c) transforming the scaler data and the scaled data into the Radon transform domain; and (d) dividing the Radon transformed scaled data by the Radon transformed scaler data; and
attenuating the coherent and incoherent noise in data in the Radon transform domain

摘要： The invention is a method to predict surface-wave waveforms (306) and subtract them (307) from seismic data. Prediction is done by estimating a set of surface-consistent components (transfer functions in the frequency domain or impulse responses in time domain) that best represent changes in the waveforms for propagation along the surface from source to receiver (303). The prediction uses a mathematical expression, or model, of the earth's filtering effects, both amplitude and phase, as a function of frequency. The desired surface-consistent components are model parameters, and model optimization is used to solve for the surface-consistent components. The surface-consistent components may include filter transfer functions for each source location, each receiver location, and for propagation (302) through each region (301) of the surface that exhibits lateral variation.
