Use of results of interpretation of scattered waves on the CSP method at the assessment of resources of the field of hydrocarbons with fracture collectors
Results of an assessment of resources of a field with fracture and cavernous type of a collector are given. The technique of complex interpretation of seismic data on the CSP method is described, allowing to receive such important parameters, as the area of distribution of a fracture collector and its thickness....
Quantative characteristics of the CSP method
The quantitative characteristics of the CSP method, which poses to estimate its effectiveness for fracture hydrocarbon reservoirs imaging using scattered seismic waves, are defined and investigated. The most important is the sensitivity coefficient, which shows how small diffractors, compared with the shadowed reflectors, may be to be detecting by ...
Efficiency of the CSP technology using in Caspian region (on the example of the North Akkar oilfield)
For the first time in the fields of the Caspian region was used the CSP technology, which makes it possible to extract the scattered waves from the full wave field. One the basis of scattered waves sections and map analysis had made the forecast of fracture cavernous reservoirs in carbonate Triassic sediments of the North Akkar oilfield. Confirmation of the executed forecast allows to recommend this technology for mapping non conventional fracture-cavernous reservoirs on other fields of the Caspian ...
Principles of geological interpretation of the scattered waves field
The basic principles of geological interpretation of the scattered waves field are represented. One the basis of scattered waves sections and map analysis had made the forecast of fracture cavernous reservoirs. These reservoirs are very perspective object for oil deposits exploration. The researchers are based on original prestack migration method — Common Scattering Point, which makes it possible to get two independent time ...
Identifying diffractors in complex acoustical media by the CSP-RTD method
The CSP (Sommon Scattering Point) method is used to identify diffrac-tors associated with cavernous fractured reservoirs of hydrocarbons. This method shows the highest efficiency in weakly inhomogeneous media. As to strongly inhomogeneous media, this method can be supplemented by the pre-liminary extension of wave field to a certain depth. To this end,...

Geopolitical regionalisation of the Baltic area: the essence and historical dynamics

However, NATO’s enlargement, which has been a source of conflict since the late 1990s, the geopolitical fracture of Ukraine in 2014, marked by Crimea’s integration into Russia, and, since 2002, the special military operation has had negative geopolitical and geo-economic repercussions on the Baltic region and collective Europe as a whole. Initially, in ...
Anagrams in the discourse of baroque ‘tacit theology’: The case of the Königsberg poetic circle of the 17th century
The problem of anagrams is linked to the paradigm secret of baroque poetry. It is shown that the essence of this poetry is a special type of poetic mimesis reflecting the existential and ontological fracture of being, which manifests itself in the lyrical persona of the poetic subject. Anagrams of the names of 17th century Königsberg poets – Simon Dach, Robert Roberthin, and Andreas Adersbach – comprise an ironical baroque reflection of the ...
The fractured reservoir of the Riphean of the Angara folds zone
This article gives an overview of the Low Angara oil-and-gas basin. The prospectively of the upper Riphean sediments of Angara folds is shown. The authors present the results of a forecast of fractured reservoir propagation in the top layer of Riphean sediments in the case of the Ilbokich license area. The article analyses scattered waves and identifies the objects interpreted as frac-tured reservoir propagation areas.
