A buried hydrophone may be configured to identify real-time changes in pipeline acoustics and vibrations during a flood event. Monitoring vibrations may allow predicting the likelihood of pipeline exposure and suspension.

Computing device, computer software and methods for generating sweep signals corresponding to plural sources that generate seismic waves. The method includes selecting a nominal sweep signal (S0); applying a perturbation (P) to the nominal sweep signal (S0); and calculating the sweep signals (Sn) by varying the perturbation (P), each sweep signal corresponding to a seismic source.

A method for aligning a vehicle at a charging station may include determining the distance between each sensor of the plurality of sensors and a target surface of the charging station. The method may further include aligning the vehicle at the charging station using the determined distance data, and charging the electric vehicle at the charging station. The method may further include using the determined distances to align the side of the vehicle substantially parallel to the target surface.

A method of measuring a flow line deposit comprising: providing a pipe comprising the flow line deposit; measuring unattenuated photon counts across the pipe; and analyzing the measured unattenuated photon counts to determine the thickness of the flow line deposit and associated systems.

A computing system and method for mitigating, in a first seismic survey, cross-talk generated by a second seismic survey. The method includes performing the first seismic survey with a first survey seismic source driven by a first survey pilot sweep, performing the second seismic survey with a second survey seismic source, simultaneously with the first seismic survey, recording with first survey seismic sensors (i) first survey seismic signals that originate from the first survey seismic source and (ii) second survey seismic signals that originate from the second survey seismic source, selecting another first survey pilot sweep, which has less cross-correlation noise with the second survey seismic signals than the first survey pilot sweep, and continuing the first seismic survey with the another first survey pilot sweep.

A seismic modeling system may include a seismic model data storage device, and a processor cooperating with the seismic model data storage device to transform a seismic model spatial domain data set associated with a given region into a seismic frequency domain data set, where the given region includes a suspect region, transform a seismic model spatial domain data subset associated with the suspect region into a seismic frequency domain data subset, and perform inpainting of the seismic frequency domain data subset based upon the seismic frequency domain data set. The processor may further convert the inpainted seismic frequency domain data subset into an inpainted spatial domain data subset, and substitute the inpainted spatial domain data subset for the seismic model spatial domain data subset associated with the suspect region in the seismic model spatial domain data set associated with the given region.

Methods of analyzing and optimizing a seismic survey design are described. Specifically, the sampling quality is analyzed as opposed to the overall quality of the whole survey. This allows for analysis of the impact of the offsets, obstacles, and other aspects of the survey on the sampling quality, which will improve the ability to compress the resulting data and minimize acquisition footprints.

A seismic data acquisition system is configured to collect seismic data. The system includes a marine source array configured to be attached to a fixed structure floating at the water surface and including vibratory source elements; and a controller configured to control the vibratory source elements so that a beam formed by the source array is steerable.
