Abstract: Various implementations described herein are directed to a method of performing a land seismic survey operation. The method may include receiving a first information from a central recording system by a computer system on a seismic truck. The first information describes time and locations of seismic shots being performed in the seismic survey operation. The method may include using a set of rules and the first information to determine a start time for a seismic shot at a next shot location. The method may also include transmitting a second information that describes the next shot location and the start time to the central recording system.

Abstract: Processing measurements to create “reflectivity” data at a datum for a target using Joint Point-Spread Functions. The “reflectivity” data can be an image or an extended image. The methods can create single reflectivity data from measurements from multiple experiments, or multiple processed datasets via different processing routes from measurements from a single experiment, or measurements from a single experiment with multiple simultaneous sources.

Abstract: Disclosed herein are implementations of various technologies for a method for seismic data processing. The method may receive seismic data for a region of interest. The seismic data may be acquired in a seismic survey. The method may determine an exclusion criterion. The exclusion criterion may provide rules for selecting shot points in the acquired seismic data. The method may determine sparse seismic data using statistical sampling based on the exclusion criterion and the acquired seismic data. The method may determine simulated seismic data based on the earth model and shot points corresponding to the sparse seismic data. The method may determine an objective function that represents a mismatch between the sparse seismic data and the simulated seismic data. The method may update the earth model using the objective function.

Abstract: A technique includes spatially filtering a signal that is derived from a seismic acquisition. The filtering is associated with a filter length, and the filtering includes varying the filter length with frequency. The filtering may be used in connection with adaptive noise attenuation, which is applied to decomposed subbands. Furthermore, the filtering may be applied during the reconstruction of the signal from the subbands.
