摘要： A technique includes determining at least one parameter to regulate actuation of a seismic source based on a frequency-based maximum deliverable output for the source. The technique includes using at least one sensor to acquire a measurement of an output of the source in response to the source being regulated using the at least one parameter and processing data representative of the measurement in a processor-based machine to selectively update the frequency-based maximum deliverable output and the at least one parameter based at least in part on the measurement.

摘要： A seismic sensor device includes an elongated housing for placement at least partially into an earth surface. A plurality of particle motion sensors are contained in the elongated housing to measure translational data in a first direction, where plural pairs of the particle motion sensors are spaced apart along a second, different direction along a longitudinal axis of the elongated housing. A communication interface communicates the measured translational data to a computer system configured to compute a gradient based on respective differences of the measured translational data of the corresponding plural pairs of the particle motion sensors, and compute one or more of rotation data and divergence data using the gradient.

摘要： Methods and systems for marine survey acquisition are disclosed. In one embodiment, a method is provided that may deploy a marine seismic spread that includes a first seismic source, a second seismic source and a streamer with a receiver. The second source may be disposed at a distance from the first seismic source in an inline direction. The distance may be selected to produce one or more pairs of shot points during a seismic survey. The shot points within a pair may be disposed within a range that is used to calculate a pressure source gradient between the shot points within the pair. The method may shoot the first seismic source and the second seismic source substantially simultaneously. The method may record seismic data associated with shooting the first seismic source and the second seismic source. The method may calculate the pressure source gradient for respective pairs of shot points.
