摘要： A method for processing seismic data. The method includes receiving the seismic data acquired at one or more receivers due to one or more marine vibroseis sources that emit one or more vibroseis sweeps. The method then applies a receiver motion correction algorithm to the received seismic data to generate receiver motion corrected seismic data. After generating the receiver motion corrected seismic data, the method transforms the receiver motion corrected seismic data into a temporal Fourier domain to generate seismic data as a function of frequency. The method then reconstructs the transformed seismic data as a function of frequency to correct for one or more motions of the one or more marine vibroseis sources. After reconstructing the transformed seismic data, the method transforms the reconstructed seismic data to the time domain. The method then generates a seismic image of a subsurface of the Earth based on the transformed reconstructed seismic data.

摘要： An apparatus includes a streamer cable section and a unit. The streamer cable section includes an associated group of seismic sensors. The unit connects to an end of the streamer cable section and includes a steering device, a controller, a network repeater and a router. The steering device is controllable to position the streamer section; the controller gathers seismic data provided by the associated group of seismic sensors and introduces the seismic data to a telemetry network of a streamer; the network repeater repeats a signal communicated along the telemetry network; and the router is disposed between the controller and the telemetry network.

摘要： A technique includes receiving particle motion data acquired by particle motion sensors while in tow. The particle motion data are indicative of a seismic signal and a torque noise, and the particle motion sensors are oriented to modulate a wavenumber of a first component of the torque noise away from a signal cone that is associated with the seismic signal. The technique includes estimating the first component of the torque noise and based at least in part on the estimated first component, estimating a second component of the torque noise inside the signal cone. The technique includes suppressing the second component of the torque noise based at least in part on the estimated second component.

摘要： A technique for processing seismic data acquired in a seismic survey conducted in the presence of a rough sea includes receiving a first dataset that is derived from data acquired by a first set of seismic sensors generally towed at a first depth in the seismic survey and receiving a second dataset that is derived from data acquired by a second set of seismic sensors generally towed at a second depth that is different than the first depth in the seismic survey. The first dataset is indicative of at least pressure measurements, and the second dataset is indicative of at least crossline particle motion measurements. The technique includes determining crossline particle motion measurements in the presence of a relatively flat sea surface based at least in part on the crossline measurements that are indicated by the second dataset and the pressure measurements that are indicated by the first dataset.

摘要： A method for processing seismic data acquired using a first over/under streamer and a second over/under streamer. In one implementation, the method may include estimating seismic data that would have been acquired by a third over/under streamer disposed at a depth equivalent to a distance separating the first over/under streamer from the second over/under streamer; and applying a dephase and sum algorithm to seismic data acquired by the first over/under streamer and the second over/under streamer and the estimated seismic data.

摘要： A gel-filled seismic streamer containing a hydrophone housing (104), which isolates a hydrophone element (102), from shear waves and mechanical forces but sensitive to pressure waves. In one embodiment, the gel-filled streamers contains a hydrophone housing with an air pocket (107), at each end for isolating a pressure sensitive hydrophone element from mechanical noise generated by cable movement during seismic data acquisition operations. The hydrophone housing further provides a protective case (103), to isolate a pressure-sensitive hydrophone element from shear waves. An inlet (109), formed in the protective hydrophone housing enables pressure waves to be communicated to the pressure sensitive hydrophone element inside of the housing. In one embodiment, the pressure sensitive housing element is a hollow gel-filled cylinder (106), that expands radially outward into a second air gap (108), formed in the housing. A protective case is also provided to isolate the hydrophone housing from shear waves. An alternative hydrophone housing for deployment inside of a streamer is also disclosed which fixably positions hydrophone or seismic hydrophone within the housing using rubber supports.

摘要： The present invention presents a method for determining shallow water flow risk using seismic data. The seismic data can be processed to enhance its stratigraphic resolution by sub-sampling the seismic data to less than a two-millisecond interval. Performing a stratigraphic analysis on the seismic data and evaluating the seismic attributes of the seismic data can be used to select a control location. A pre-stack waveform inversion is applied to seismic data at a selected control location to provide an elastic model, which includes pressure-wave velocity and shear-wave velocity. The shallow water flow risk is then determined using the elastic model by comparing the pressure-wave velocity to the shear-wave velocity. A post-stack inversion can be applied on the seismic data using the elastic model to model a 3D volume to determine the shallow water flow risk across the 3D volume.

摘要： The present ivnention, in certain embodiments, discloses a method for acquiring marine seismic data using a seismic acquisition system where shot points are determined and shot records recorded. A time at which the source vessel will be substantially at a shot point position is predicted and the seismic source is activated at the shot point. The shot is recorded and the next location for recording a shot is determined. If the source vessel has passed the determined next shot point position, the seismic source is activated and a shot is recorded. If the source vessel has not reached the next shot point, a time delay is implemented until the shot point is reached. The method allows for efficient acquisition of seismic data under varying field conditions by resembling a distance based shot point determination method unless a time based acquisition method becomes more appropriate due to field conditions or other operational considerations.
