OBJECT-ORIENTED CORRELATION AS A NEW METHODOLOGICAL APPROACH IN THE PREPARATION OF DATA FOR SEISMIC FACIES ANALYSIS

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

Seismic data contain a large amount of useful information. Previously, it was suggested that basic information for seismic facies analysis is contained in the unstable, weak and chaotic reflections. Modern research confirms these ideas. This allows you to correlate seismic horizons more details, especially phantom horizon and also to perform a detailed correlation of individual objects. The authors called their method the object-oriented correlation.......

SPECIALTY OF SHELF LAYER BS8 SEISMO-GEOLOGICAL SUBSURFACE MODEL BUILDING OF UPPER-SALYM FIELD

(Korochkina N.S. )

Coordination methodology of achimovsky deposits and shelf sediments of the cyclothem BS8 has been studied in Upper Salym field. The job is done based on 3d seismic and geological model complexing with the using sedimentological, core and log interpretation. After that as Achimov seismo-geological model has been built based on seismic dynamic attributes the achimov reflectors have been picked inside the cyclothem BS8 according core and log data. As a result the lensoid seismo-geological model of shelf layer BS8 is obtained. Pinchout lines of shelf sublayers are delimitated.......

THE EFFECTIVE THICKNESS OF THE NEOKOM DEPOSITS PREDICTION USING SEISMIC DATA AND FACIES MODEL

(Ekimenko A.V. )

The paper discusses an example of a forecast of effective thickness based on seismic data and facies models of the reservoir. In the study, the analysis of thickness for wells in the different facies zones was performed. Based on variogram analysis the parameters of the spatial anisotropy were estimated. Regression analysis of well and seismic data and geostatistical interpolation for thickness of sand were done.......

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.......
