FIELD: oil and gas production.
SUBSTANCE: seismic exploration operations, well geophysical researches and core lab researches are carried out. According to core lab researches and well geophysical researches data there revealed are interrelations of formation filtration reservoir characteristics and reference logs. Formation structures are revealed by summarised data of seismic exploration operations and well geophysical researches. Formation filtration reservoir characteristics and relative position of parts comprising the formation are defined on the basis of widespread reference logs in interwell space of unexamined formation areas and obtained interdependence of formation filtration reservoir characteristics and reference logs. Note that in the course of well geophysical researches additionally there performed is at least one type of logging. Note that additional logging is done in any well. Formation filtration reservoir characteristics and relative position of formation parts are defined by means of confirmed Fourier analysis of changing of all obtained reference logs in interwell space.
EFFECT: improvement of determination accuracy of formation filtration reservoir characteristics and relative position of parts comprising the formation.
