RESOLUTION OF CROSS-WELL TRAVEL-TIME TOMOGRAPHY
The resolution of cross-well travel-time seismic tomography is investigated using synthetic models with different initial velocity patterns and acquisition conditions. Namely, resolution is tested for different positions and spacings of sources and receivers, wavelet frequencies, and starting velocity models (with a single localized velocity anomaly or with periodic (checkerboard) positive and negative anomalies). The modelling results can be used to choose the optimal source-receiver configurations for controlled-source cross-well tomography and to estimate the resolution limit related to the finite wave length.

DETECTION AND CHARACTERISATION OF FRACTURE SYSTEMS FROM P-TO-S SCATTERING: POTENTIALITY CHECKS BY PHYSICAL MODELLING AND SIMULATIONS
Physical modelling is applied to verify seismic responses of fractured reservoirs predicted by gridcharacteristic simulations. The physical model agrees with the numerical solution and confirms that clusters of 100 m long fractures (macrofractures) show up in seismic responses as stable and prominent events: wave fronts of converted (P-to-S) scattering off the fracture ends. Asymmetry of responses (difference between wave patterns acquired left and right of the shot) revealed in the course of physical modelling makes detection of fracture clusters ever more efficient. The results allow outlining further prospects for characterisation of fractured reservoirs from P-to-S scattering.

MULTIFOCUSING AND STANDARD SEISMIC
Multifocing is a relatively new seismic imaging technology that started to be commercially used about ten years ago. Since that time, it has demonstrated high performance in a wide variety of sedimentary basins. Nevertheless experts continue to have reservations about the multifocusing technology that may be caused by several reasons. Particularly, publications on multifocusing fundamentals usually consider complex media models complicating understanding of the technology. Another possible reason is that authors apply ray tracings in depth domain when considering events in multifocusing, while in standard technology they mainly use time domain for these purposes. Furthermore, the notion of t-x curve is disregarded in publications on multifocusing, despite of its importance for understanding of any seismic method. This paper offers analysis of the abovementioned and other peculiarities of the multifocusing elucidation, as well as their comparisons with the standard technology solutions. Despite the paper considers simple 2D models, it touches upon some aspects of reflection seismology fundamentals.

HOMOMORPHIC FILTERING AND BLIND DECONVOLUTION
So long time in an area of filtering researches a big stream is development. It provides to separate a form of observed signals on multiplied or convoled components. In the filtering does not use or use minimum information about separated components nature as well as don’t need full knowledge about processes which its forming. All give a tripled effect. The first, heuristics models can be applied for a signal form presentation. The second, components are determined by such filtration are the bases for a studying of processes which can available these variations of observed signals form. The third, separated components take account on used models are applied to the signals form correction or entrance data for inverse problems solution. In the last case known theoretical solutions or some heuristic design which are basis for studying of processes of recorded signals formation can be used. Thus, developing the direction has great prospects in seismic exploration especially given the increasing complexity of tasks and requirements to improve the accuracy of features prediction of studied medium. One of the most well-known methods, which is based on the homomorphic filtration ideas, is the surface consistent filtering representing the standard procedure of all modern package of seismic data processing.

QUALITY AND QUANTITY OF VIBROSEIS DATA AND SIGNAL-TO-NOISE RATIO
The criteria of field vibroseis data quality are changing at new (fifth) technological level of 3D land seismic characterized with single-source and single-sensor acquisition, wider bandwidth, high density, high productivity, and almost continuous data recording. It has been shown that traditional field procedures such as geophone grouping and vertical stacking are not necessary anymore if the trace density is high enough. Supervisors will change their focus from visual and quantitative estimation of raw correlated data to verification of the field techniques selected by the Client.

NEAR-SURFACE ANOMALIES: REMOVING BY STATIC CORRECTION OR INCLUDING INTO LAYERED MODEL?
Near-surface heterogeneity complicating the time curves of reflections from deep interfaces poses problems to velocity analysis. The conventional static correction (datuming) can simplify the curve shape but the use of such corrected times in a layered velocity-depth model causes additional distortion or even makes the modelling impossible. As an alternative approach, a more precise layered velocity-depth model can be obtained with times reconstructed from depth migration images (redatuming), while static corrections are applied to residual time shifts after inversion.

INTEGRATED GEOPHYSICAL APPROACH FOR TESTING GROUND SLABS
Large in-situ reinforced concrete structures are broadly used in the modern construction practice. The properties of concrete ground slabs are studied with an integrated approach jointly by ultrasonic, sonic, and radar (GPR) testing methods. The approach allows investigating concrete volumes of different sizes in terms of their integrated properties, as well as the state of subgrade at the slab—ground contact. The testing results are interpreted with regard to dispersion (frequency dependence) of velocity and attenuation.

TECHNOGENICALLY CHANGED NEAR-SURFACE ROCKS OF SEMIPALATINSK TEST SITE BASED ON SEISMIC DATA
We consider the near surface seismic structure on the location site of the borehole nuclear explosions. Observations of refracted waves on eight parallel profiles with a length of 6 km and a distance between them of 500 m were used. Velocity structure to a depth of 200–250 m is defined by forward ray tracing. Technologically modified layer of rocks is detected in the area of the explosive holes. Layer has a thickness of 40–80 m and the velocity therein is reduced by 1–2 km/sec as compared to the intact rocks. Layer located under the low velocity zone at a depth of 20–70 m, and its thickness varies in proportion to the weight of the nuclear charge.
