Patent number: 10996360Abstract: According to one embodiment, there is provided a method of correcting recorded seismic data where each receiver clock is potentially inaccurate. Since the seismic wave field is not random, and contains coherent events that are recorded by all receivers in a local area, it is possible to estimate the differences in the time reference by comparing the recordings of different receivers in a local area. With no external time reference, time signal, or pilot trace, an entire seismic data itself can be used to determine how each receiver's clock is drifting from true time.Type: GrantFiled: December 5, 2016Date of Patent: May 4, 2021Assignee: BP CORPORATION NORTH AMERICA, INC.Inventor: John Theodore Etgen
