Pseudorandom sweeps for simultaneous sourcing and low-frequency generation

  title={Pseudorandom sweeps for simultaneous sourcing and low-frequency generation},
  author={John J. Sallas and John Gibson and Peter Maxwell and Forest Lin},
Over the past decade, there has been rather vigorous activity in developing simultaneous sourcing and slip-sweep techniques for vibroseis acquisition. Such methods include HFVS and C-HFVS (Krohn et al., 2010), ISS (Howe et al., 2008), DSSS (Bouska, 2010), and HPVA and V1 (Meunier and Bianchi, 2002). These methods provide improved vibrator productivity and create a means of cost-effectively improving source density and thus spatial sampling. Egan et al. (2010) have discussed the link between… 

Surface and downhole recording of pseudorandom vibroseis sweeps

The use of pseudorandom sweeps has received periodic attention over the last 45 years. Previous testing has indicated that hydraulic vibrators may struggle to transmit such sweeps due to their rapid

The use of pseudorandom sweeps for vibroseis surveys

Pseudorandom vibroseis sweeps have long been suggested as an alternative to standard linear sweeps due to their potential for having superior orthogonality, a lower likelihood for infrastructure

Establishing The Limits Of Vibrator Performance - Experiments With Pseudorandom Sweeps

Tests showed that vibrators can struggle to emit pseudorandom sweeps, particularly if they contain segments of the same polarity, sudden changes in instantaneous frequency, or small amplitude/high-frequency fluctuations.

Method of designing pseudorandom sweeps suitable for ISS acquisition

There is a weak cross-correlation between the pseudorandom sweeps generated, and, based on this property, two different types of aliased datasets for ISS acquisition are simulated, showing that while both kinds of acquisition methods partially suppress noise from adjacent shots, the latter shows a better suppression effect.

Methods of Minimizing and Suppressing the Correlation Noise of Simultaneously Operating Sources in a Vibroseismic Survey

Abstract—A seismologiсal survey with several simultaneous sources provides more data per time unit than a conventional one with a single source, and presents an opportunity to improve the seismic

Field testing of multiple simultaneous vibrator sources controlled by filtered m-sequences

Summary Theoretical analyses and numerical simulations predict that shifted m-sequences form quasi-orthogonal signals that are suitable pilots for driving multiple simultaneous land vibrators. Field

Combined focal and coherency-based deblending strategy

This work proposes using the output of a coherencybased deblending algorithm to provide a starting model for a sparsity-based deb lending algorithm that uses the focal transform as its main engine and shows that this strategy can be beneficial when the deblended solution does not have a sufficiently sparse representation in the transform domain.
