Abstract: A method for determining interference noise recorded in a first seismic survey of a subsurface generated by a source in a second seismic survey. The method includes receiving seismic data recorded by seismic sensors of the first seismic survey, wherein the seismic data includes seismic waves that originate from the first seismic survey and seismic waves that originate from the second seismic survey; receiving actual relative shooting timing or actual shooting timing of seismic sources of the first and second seismic surveys; applying a processing algorithm to the seismic data to calculate the interference noise, wherein the processing algorithm that takes into consideration the actual relative shooting timing or the actual shooting timing of the seismic sources; and generating a final image of the subsurface based on the recorded seismic data from which the interference noise is subtracted.

Abstract: Computing device, computer instructions and method for processing input seismic data d associated with a surveyed subsurface. The method includes: receiving the input seismic data d recorded in a first domain by seismic receivers that travel in water, the input seismic data d including pressure data and particle motion data; generating a model p in a second domain, which is different from the first domain, to describe the input seismic data d; processing the model p to generate an output seismic dataset with attenuated noise; and generating an image of the surveyed subsurface based on the output seismic dataset.

Abstract: Methods and devices for seismic data processing deblend seismic data gathered using simultaneous source acquisition by applying two different deblending techniques. The second deblending technique is applied to residual data obtained after applying the first deblending technique. At least one of these first and second deblending techniques uses a signal-to-noise map.

Abstract: Methods and systems for processing data acquired using a variable-depth streamer, obtain up-going and down-going wavefields at a predetermined datum, and use them to identify multiples included in the up-going wavefield. An image of a geological formation under the seabed is then generated using the data from which the multiples have been removed, and/or the multiples.

Abstract: System, medium and method for de-blending seismic data. The method for acquiring blended seismic data associated with a subsurface of the earth includes receiving coordinates of a sail line associated with first and second shot point locations; towing first and second source arrays in water along the sail line; shooting the first and second source arrays with a constant delay parameter so that a seismic trace recorded by a seismic sensor has at least a first uncontaminated portion that includes seismic energy generated substantially only by one of the first and second source arrays and a second portion that includes seismic energy generated by both the first and second source arrays; and recording blended seismic data generated by the first and second source arrays with the seismic sensor.

Abstract: A system and method are provided for reducing jitter in collected seismic data. The collected seismic data includes both original seismic data, e.g., original traces, and other seismic data, e.g., interpolated traces. The collected seismic data is filtered to form filtered seismic data, and then the original seismic data is re-inserted into the filtered seismic data. Filtering is repeated on the result based, for example, on one or more filter thresholds that progressively relax constraints on the filtering process, until the filtered data can be combined with the original seismic data with a good fit or a predetermined, e.g., user determined, number of times.
