摘要： To perform an electromagnetic (EM) surveying of a subterranean structure, a signal generator produces a signal having an analog continuous waveform without steps in the waveform. Producing the signal is in response to an indication specifying a characteristic of the signal. An antenna is responsive to the signal having the analog continuous waveform to emit an EM field to produce the EM surveying of the subterranean structure.

摘要： A seismic survey system includes a winch having a winch cable coupleable to a source array towable between two deflected lead-ins, a positioning system for determining a current position of the source array and a controller for adjusting the winch to modify the current position of the source array to a desired crossline position. The winches may be attached to the deflected lead-ins or mounted on a tow vessel. The winches exert lateral forces on the source array, derived from the deflected lead-ins, to control the inline position of the source array. A method includes positioning a seismic source array in tow behind a vessel comprises determining a current position of the source array and adjusting a lateral force applied to the source array to move the source array to a desired crossline position. Optionally, by adjusting the gun cable winch, the inline position may be controlled.

The method includes receiving an unmigrated set of spatial wavelets, wherein the unmigrated set of spatial wavelets include unmigrated spatial wavelets in the time domain. The method includes receiving a first migrated set of spatial wavelets, wherein the first migrated set of spatial wavelets includes migrated spatial wavelets in the depth domain. Each spatial wavelet comprises information about spatial location, orientation, amplitude, wavelet, acquisition configuration, and coherency. Each spatial wavelet in the unmigrated set of spatial wavelets is linked to a spatial wavelet in the first migrated set of spatial wavelets. The method includes selecting spatial wavelets from the first migrated set of spatial wavelets that are within or slightly outside the VOI; selecting a target set of spatial wavelets, the target set of spatial wavelets including spatial wavelets from the unmigrated set of spatial wavelets that are linked to the selected spatial wavelets from the first migrated set of spatial wavelets; migrating the target set of spatial wavelets using one or more of a new velocity model to create a second migrated set of spatial wavelets; and synthesizing the second migrated set of spatial wavelets into a new seismic volume and synthesizing the second migrated set of spatial wavelets into one or more new seismic gathers.

摘要： A method of processing seismic data that includes including first and second modes of seismic energy where the second mode has been generated by partial mode conversion of the first mode at a boundary face of a layer of the seabed includes the step of cross-correlating a trace acquired at a receiver and including events corresponding to the first mode with a trace acquired at the same receiver and including events corresponding to the second mode. An event in the cross-correlated data that corresponds to partial mode conversion is identified, and the amplitude of this event is normalized, for example relative to the amplitude of the peak in the cross-correlogram at zero time delay. Information about the effects of the static shift produced by the layer and/or about vector infidelity can be arrived from normalized cross-correlograms for receivers in a receiver array.
