Abstract
As a matter of experience performance of seismic inversions for various geological tasks it is possible to draw a conclusion that the choice between deterministic and geostatistical methods needs to be made, proceeding from the set of geological objects and degree of study of the field. At an initial stage of development of the field it is enough to perform integrated forecast for deterministic inversion allowing to reveal zones of development of reservoirs with improved properties. In case it is necessary to specify a deposits structure during creation of geological model, planning of development drilling, in particular for a difficultly constructed and strongly changing on lateral reservoirs, it is necessary to use a method of geostatistical inversion. Possibilities of more objective forecast of petrophysical parameters of sandy reservoirs are extending, because of use of seismic data inversion in a complex with a structural factor, petrophysical modelling data, on the basis of knowledge of formation and a structure of oil-and-gas complexes of the region.
