FIELD: physics.
SUBSTANCE: in order to select the point of location and structure of a well, magnetotelluric investigations and seismic investigations while detecting shear waves in order to determine the structure of the subtrappean space are performed first. Further, results of investigating the core material are used to determine the lower edge of the trapp, and results of well investigations and VSP-OVP in a system with results of seismic investigation by shear-wave technique are used to search for hydrocarbon deposits.
EFFECT: high accuracy of surveying geological environments in a sedimentary reservoir covered by a trappean cover.
