GRAVIMETRIC RESEARCH OF THE EARTH CRUST ON RUSSIAN AND PECHORA PLATES WITH THE VECTOR SYSTEM

(Tarantin M.V. Kostitsyn V.I. Prostolupov G.V. Chadaev M.S. Gershanok V.A. )

In this paper, we present the research of the Earth's crust of the north-eastern part of the East European Platform (Russian and Pechora plates). The results are obtained with the data processing and analysis method for constructing deep gravimetric sections in the Vector system. The prediction examples of the inhomogeneities of the lower crust structure are given, including the Moho discontinuity location.......

THE POSSIBILITY OF SHALLOW WELLS USING TO IMPROVE THE INITIAL SEISMOGRAMS QUALITY IN MICROSEISMIC MONITORING OF HYDRAULIC FRACTURING

(Shulakov D.Yu. Shumilov A.V. Chernyh I.A. Ovchinnikova E.A. )

This article considers the possibility of using shallow boreholes to improve the quality of seismograms during microseismic monitoring of hydrofracturing from the earth's surface. It is shown that installing the sensor in a 10 m deep borehole makes possible to achieve a significant reduction of the level of microseismic noise in the frequency range above 8 Hz. In addition, this significantly reduces the absorption of the high-frequency component of the signal (80-140 Hz) in the near-surface rocks.......

INVERSE ROCK PHYSICS: RESERVOIR CHARACTERIZATION OF THE TYUMEN FORMATION

(Shubin A.V. Ryzhkov V.I. Klyazhnikov D.V. )

We performed deterministic reservoir prediction based on inverse rock physics modeling for two oilfields in the West Siberia, Russia. The target zone is Tyumen formation. It consists of a thinly laminated sand-shale-coal sequences. The idea of the proposed method is to calibrate the rock physics model and then apply it in reverse direction for reservoir properties evaluation. In this case, the input data are elastic attributes, the output will be reservoir properties. We applied Bayesian approach for rock physics inversion. As a result, we transformed seismic scale elastic attributes P-impedance and S-impedance into reservoir parameters: volume of sand, volume of clay, volume of coal and porosity.......

PREDICTION OF NON-STRUCTURED HYDROCARBON TRAPS IN THE TRIASSIC DEPOSITS OF THE CENTRAL PART OF THE ZHETYBAI-UZENSKAYA STEP

(Ryzhkov V.I. Danko D.A. Bars F.M. Osintseva N.A. Matveeva A.N. Nurgaliev K.Zh. Makhmudov R.A. )

The article describes the Triassic deposits geological structure and sedimentation conditions of the central part of the South Mangyshlak Zhetybai-Uzen stage with the aim of predicting of non-structural type traps. As a result of a comprehensive study of 3D seismic data and geophysical well survey data within the study area, it was possible to identify a trap in medium Triassic carbonate organogenic buildup and a trap associated with Upper Triassic turbidite sediments.......
