SEISMIC VIBRATOR QUALITY CONTROL

(Belousov A.V. Shneerson M.B. Frolov A.S. Gribov E.N. )

Problems of seismic vibrator quality control during seismic surveying have always been important. At the same time, the possibility of independent control of equipment parameters is critical for objectiveness of QC (i.e., for vibrator matching). In most cases supervisor have to use the data provided by the seismic crew specialists who have built-in hardware quality control systems. Nowadays the most of seismic stations provides the possibility to write the data from vibrators accelerometers into SEGD. The lack of unified and regulated methods to calculate the evaluation of the vibration creates some problems in analyzing reports and leads to the prevalence of expert (subjective) evaluation.......

WINDOW ESTIMATIONS USAGE IN SEISMIC SURVEY QUALITY CONTROL

(Karapetov G.A. Belousov A.V. Frolov A.S. )

Window estimations can be considered as the one of the most useful methods of quality control. At the same time, the correct determination of the size, shape of the windows and the order of calculation can dramatically affect the accuracy and correctness of the final results. This article is devoted to a detailed consideration of the choice of parameters for regulatory and standardization purposes. Key words. Seismic survey, quality control.......

THE RESULTS OF ELECTRIC SURVEY AND ARCHAEOLOGICAL RESEARCH OF THE FOREST MOUND GROUP OF THE GNEZDOVSKY ARCHAEOLOGICAL COMPLEX

(Vlasov D.A. Novikov V.V. Kainov S.Yu. Sergeev K.S. Gorin A.D. )

The paper presents the results of a study of five big mounds of the Gnezdovsky archaeological complex by the method of electro-tomography. It is shown that electro-tomography makes it possible to determine violations of kurgan embankments and structural elements. Archaeological excavations can confirm or disprove the results of geophysical studies or “calibrate” the methodology of work.......

OBJECT-ORIENTED SEISMOGEOLOGICAL ANALYSIS AS A NEW APPROACH TO SEISMIC DATA INTERPRETATION

(Olneva T.V. Ovechkina V.Yu. )

The method of object-oriented approach of seismic data interpretation was formed in the process of finding solutions for increasingly complex problems of oil and gas fields study. Organization of seismogeological monitoring for placement of production and exploration wells on the basis of conceptual models, interactive feedback with drilling data allowed to make sure that even minor variations of the wave field, initially taken for interference, can carry geological information. Object-oriented seismogeological analysis implies not only a detailed correlation, but also a further geological interpretation, reconstruction of the sedimentation environment, search for modern analogues, typification and systematization of seismic images, etc. Ehe article demonstrates an example of object-oriented interpretation on the materials of the Priobskoye field.......
