Abstract

In sedimentary rocks, zones of excessive fissuring are often superimposed on porous and cavernous reservoir types, creating and complicating traps of non-structural hydrocarbons. Traps of this kind are hard to find and usually not detectable with standard CDP seismic survey methods. Non-standard approaches are needed in the implementation of their successful forecast. For this it is possible to use the properties of both scattered and specular reflected waves, on the basis of which a number of unique techniques have been created. In particular, these include the Prony filtration method, that allows for the frequency-dependent analysis of the wavefield, on the basis of which it is possible to successfully predict oil-and-gas bearing features of any complexity. The article provides an example of application of the Prony filtration method from the practical experience of the authors.
