摘要： In accordance with the present invention, there is provided a method of determining whether a particular high fidelity vibratory seismic survey phase encoding is likely to be a good one based on an analysis of the eigenvalue structure (i.e., eigenvalues, eigenvalue separation, condition number, and model resolution matrix) of a matrix formed from the Fourier transforms of the sweep signals. Preferably, a singular value decomposition will be used to calculate the eigenvalues. Using this same approach, the condition number and eigenvalues of matrices that are associated with multiple proposed designs can be compared with each other to determine which is likely to be yield the best seismic data. This approach is preferably used either as a component of the advanced planning for a survey or in the field during pre-survey testing. The use of the instant approach to determine an optimal phase encoding scheme is also taught.

摘要： A method and apparatus for minimizing interference between seismic systems. The method may generally include: (a) actuating a plurality of first sources associated with a first seismic system to generate a first plurality of phase-encoded vibratory signals; (b) actuating a plurality of second sources associated with a second seismic system to generate a second plurality of phase-encoded vibratory signals that are at least partially frequency separated from the first plurality of phase-encoded vibratory signals generated in (a); and (c) detecting the first and second plurality of phase-encoded vibratory signals utilizing a first receiver positioned at a location remote from the first and second sources.

摘要： The invention relates to a process for two separate seismic crews to work in proximity to one another that would otherwise require expensive time sharing where one crew is a conventional seismic acquisition system and the other is a phase encoded seismic acquisition system. Typically, each recording system would receive seismic energy from the other that neither data set would be very useful. The invention primarily envisions some collaboration between the crews where each adjusts its sweeps to comprise a different time duration so that the energy the other crew's sources are distinguishable in the data set and easily eliminated therefrom. Distinctions may be further enhanced when the two crews use construct their sweeps so that each crew has a distinctly different start frequency and a distinctly different end frequency.
