SEISMOSTRATIGRAPHIC APPROACH FOR RESTORING THE CONTINUITY OF GEOLOGICAL EVENTS

(Olneva T.V. )

The article is devoted to study of geological events in the geological history of the long-lived suture zones of the base. Traditional approaches seismostratigraphic and seismic facies analysis allow us to identify the most informative intervals and their associated geological features. In the process of interpretation was established that the contact of blocks in the base manifests itself in different time intervals through the presence of paleochannels, alluvial fans, landslides. Transport of the mass was carried out with preservation of the s-n direction. Within the study area are several small oil and gas fields.......

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.......
