In-field quality control at new technological level of land seismic

(Cherepovskiy A.V. )

The modern criteria and wide possibilities of in-field quality control of 3D land seismic data have been described. The approaches to in-field QC are changing at new technological level of 3D land seismic characterized with single-source and singlesensor acquisition, high density, high productivity, and (almost) continuous data recording. It has been shown that in-field QC in mega-crews should inevitably transform from visual and quantitative estimation of raw data to verification of the specifications and field techniques selected by the Client. And the quality of seismic surveys should be estimated on the final results of data processing and interpretation.......

Estimation of seismic effect drilling-and-blasting operations for buildings

(Verkholantsev A.V. Shulakov D.Yu. )

The article describes the results of analysis of seismic effect measured for single explosions in mines and open pits. It is shown the main factors that influence on seismic effect magnitude are not only distance and explosive mass but also triggering direction, system of initiation and rock properties near the surface. It means that formula to estimate seismically safe distances established by regulatory documents is suitable only for initial rough calculation. Reliable determination of amplitude-to-distance dependence is possible only after in-situ measurements taking into account both blast parameters and soil conditions. The resulting value of seismically safe distance can differ significantly (in times) from that calculated with statutory formula.......

Seismic-acoustic emission of producing formation in detection and extraction technology

(Shumilov A.V. Dryagin V.V. Ivanov D.B. Nigmatullin D.F. )

The results of studies of seismic acoustic emission occurring in the oil-saturated porous geological environment with acoustic impact force in the well. It is show that the dynamic nonlinear process in the reservoir activated when the external elastic impact on deposit and as a consequence alter the energy state of the environment, which is reflected in the change of the acoustic emission. The parameters of the seismic acoustic emissions uniquely associated with the character of the productive formation saturation and permeability.......
