Carbonate stractures forecast by stratum acoustic inversion in Leno-Tungusskay oil and gas province

(Kondratiev I.K. Bondarenko M.T. Tarasenko E.M. Kissin Yu.M. Kucherya M.S. )

It is demonstrated the possibility of identifying reefogenous buildings on seismoacoustic sections obtained by means of stratum acoustic inversion. This article shows the high efficiency of stratum acoustic inversion in case of processing low quality seismic data and use the logs data of two drilled wells transferred through 300 km of regional seismic profiles.......

Petrophysical models of terrigenous collectors on the Nepsky arch

(Baryshev L.A. Vashenko V.A. )

In article petrophysical models of terrigenous collectors constructed according to geophysical well logging in the territory of the Nepsky arch are considered. Dependences of capacitor characteristics of reservoir on a saline factor are established. On the basis petrophysical models physical justification for allocation of the perspective electric and seismic anomalies connected with oil and gas deposits is given.......

Seismic facies analysis range of possibilities for the study of landslide

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

Creation of library of seismic patterns representing geological processes and phenomena is a challenging and actual task. Thanks to recent researches and, in the first place, the interpretation approaches based on seismic stratigraphy and seismic facies analyses we are able to do this. The authors are planning a series of papers devoted to different geological processes and phenomena.......

Deformation characteristics of Quaternary clay soils on the results of engineering-geological and ultrasonic research

(Pioro E.V. Oshkin A.N. Vladov M.L. Nikolaeva S.K. )

The article is devoted to the search of correlations between the indices of deformation properties of clay soils, obtained under static loading and ultrasonic scanning. Research were conducted on natural Quaternary and artificial (made from pastes), clayey soils. The study of the deformation properties was carried out using a oedometer test, uniaxial compression and laboratory ultrasonic. According to the results of the tests obtained by equation correlation of the Young’s modulus of with initial compression module and relative modulus of deformation (according to the results of uniaxial tests) module and oedometer modulus (compression tests), described by exponential laws for both model and natural Quaternary soils.......
