CREATION OF THE STRUCTURAL AND FACIES MODEL BASED ON SEISMIC DATA FOR MODELING OF THE PANNONIAN BASIN

(Olneva T.V. Dulich I. Bogichevich G. Rodionov A.E. )

In the period from 2014 to 2015 were carried out on large-scale the regional synthesis of geological and geophysical data within the Pannonian basin. Structural basis for the regional basin model was created by integrated interpretation of seismic and well data. Hard data were represented 3 251 wells (554 taken as reference); 81 582 km 2D seismic and 15 697 km2 3D seismic. The obtained results of wwells orks marked a new phase in regional geological synthesis and represent rich material for the further understanding of the geological structure of the region.......

SEISMIC-GEOLOGICAL MONITORING: GOALS, CHALLENGES, SOLUTIONS

(Ovechkina V.Yu. Karanov V.V. Rafikov R.R. )

Gazpromneft has set an ambitious goal - to increase oil production. This issue cannot be addressed without drilling of the zones whose reserves quality becomes progressively worse thus increasing geological and investment risks. To raise drilling profitability and effectively involve new zones and formations into development innovative scientific methods are required that allow making operative decision regarding drilling as new geological and production information becomes available. Over recent years seismic-geological monitoring of production drilling is widely used for the development of Gazpromneft major oil fields. What the main tasks of this stage are? What the specificity of work with seismic data is and what to expect basing on the physical limitations of the method? These are some of the topics the authors are addressing in this article by the example of one of the oil fields in Western Siberia.......

THE EXPERIENCE OF CONSIDERING THE GAS CAP INFLUENCE IN STRUCTURAL INTERPRETATION IN CONDITIONS OF LIMITED INPUT DATA

(Butorin A.V. Vasiliev M.A. )

One of the factors of uncertainty in the estimation of structure is the influence of massive gas deposits in the upper part of the section, which affects the dynamic parameters of the field, and on its kinematics, i.e. two-way-time. In the absence of a detailed velocity model, considering the influence of gas-saturated interval, estimation of this factor is difficult and can lead to errors in determining the structure of the target horizons. The article describes the approach of compensation of the gas deposit influence on two-way-time in a limited amount of input data.......

CREATION OF SEISMOGEOLOGICAL MODELS ACCORDING TO 2D SEISMIC EXPLORATION AND WELLS DATA (ON THE EXAMPLE OF AN AREA OF THE PREDPATOMSKY DEFLECTION OF EASTERN SIBERIA)

(Abrosimova O.O. Yanevits E.A. )

This paper is dedicated to a problem of seismogeological modelling of complex sedimentary deposits according to 2D seismic data. Possibilities of interpretation by the attribute analysis and the algorithms realised in Hampson Russell software are showed on an example of carbonate depositions of Eastern Siberia.......

LOCALIZATION OF THE NOT IVOLVED IN DEVELOPMENT PLAYS BY LOG AND SEISMIC DATA ANALISYS

(Ekimenko A.V. Glushenkov D.A. )

Authors performed the joint analysis of seismic and well logging data for automated mapping of the lower Cretaceous productive layers in the Vyngapurovskoe field. Automatic searching aim intervals were implemented. The most promising for drilling part of the field was mapped base on seismic data analysis.......
