“…When designing a survey or assessing a given acquisition geometry, common midpoint‐based attributes such as fold and sampling at different offset as well as azimuth ranges are widely used, as illustrated in Cordsen, Galbraith and Peirce () and Vermeer (). Although they can quickly provide beneficial information on the anticipated data quality from a given acquisition geometry, these attributes inherently disregard the effect of processing.…”

The application of blended acquisition has drawn considerable attention owing to its ability to improve the operational efficiency as well as the data quality and health, safety and environment performance. Furthermore, the acquisition of less data contributes to the business aspect, while the desired data density is still realizable via subsequent data reconstruction. The use of fewer detectors and sources also minimizes operational risks in the field. Therefore, a combined implementation of these technologies potentially enhances the value of a seismic survey further. One way to encourage this is to minimize any imperfection in deblending and data reconstruction during processing. In addition, one may derive survey parameters that enable a further improvement in these processes as introduced in this study. The proposed survey design workflow iteratively performs the following steps to derive the survey parameters responsible for source blending as well as the spatial sampling of detectors and sources. The first step is the application of blending and sampling operators to unblended and well‐sampled data. We then apply closed‐loop deblending and data reconstruction. The residue for a given design from this step is evaluated and subsequently used by genetic algorithms to simultaneously update the survey parameters related to both blending and spatial sampling. The updated parameters are fed into the next iteration until they satisfy the given termination criteria. We also propose a repeated encoding sequence to form a parameter sequence in genetic algorithms, making the size of problem space manageable. The results of the proposed workflow are outlined using blended dispersed source array data incorporating different scenarios that represent acquisition in marine, transition zone and land environments. Clear differences attributed solely to the parameter design are easily recognizable. Additionally, a comparison among different optimization schemes illustrates the ability of genetic algorithms along with a repeated encoding sequence to find better solutions within a computationally affordable time. The optimized parameters yield a notable enhancement in the deblending and data reconstruction quality and consequently provide optimal acquisition scenarios.

“…For surface‐wave analysis and inversion, the use of 3D geometries is not a limitation. Cross‐spread geometry (Vermeer ) is widely used in 3D land seismic surveying and provides a complete sampling of the surface‐wave propagation also in the offset and azimuth and a large statistical redundancy for the surface‐wave analysis (compare Fig. ).…”

While in other domains of applied geophysics the surface‐wave is considered a source of information for near‐surface characterization, in the seismic industry the so‐called ground roll has been traditionally regarded only as coherent noise to be filtered out as soon as possible. This difference of perspective is mainly due to the limitations of conventional land acquisition. The Rayleigh waves, which constitute a large part of the recorded energy, can be acquired properly, analysed and inverted to characterize the near‐surface with a surprisingly high resolution, even in large 3D surveys, with point receiver acquisition. Surface waves can play a new role: they contribute to a better near‐surface characterization for the perturbation correction and can be used for velocity modelling and geological modelling. Their proper identification enables alternative filtering strategies. Surface waves are not coherent noise but a signal that can be lifted from the seismic record and exploited in a variety of well‐established geophysical solutions. In this paper we discuss a workflow for the analysis, inversion and attenuation of surface waves with 3D land data, showing examples from a land 3D survey in Egypt.

“…On the other hand, if the station spacing is greater than the Nyquist sampling interval, the data will not adequately define steeply dipping reflectors or hyperbola diffraction tails. In areas of flat‐lying reflectors, this criterion can be compromised (Vermeer, 2002).…”

Indoor archaeological sites are particularly adapted for ground-penetrating radar (GPR) surveying because the environment is uniform throughout the year.This makes them excellent for the application of meticulous three-dimensional surveys under repeatable conditions. The objective of this work was to test different dense grid strategies and three-dimensional imaging techniques in order to improve detection of subfloor targets. Application of the isosurface rendering technique to pseudo-three-dimensionalvolumesresultedin an efficient methodology to mapthe target inthis particular case. This work shows a case history carried out at the convent of Santo Domingo (Lugo, Spain) where a sarcophagus was found.
