New methods for interpreting seismic waves in stratified media
Abstract
In order to ensure the most complete exploitation of petroleum deposits it is essential to develop new methods for the study of faults and the steep slopes of salt domes. The author describes a method for achieving this goal. This involves interpretation of reflections directly from fault zones: direct waves from the boundaries of fault zones and doubly reflected waves (those forming first by reflection from a subvertical boundary and then from the subhorizontal boundaries adjacent to them). It is shown that the formation of such duplex waves does not require that the entire subvertical boundary be continuously reflecting; it is only required that its individual elements in the neighborhood of the contacts with the subhorizontal boundaries have reflecting properties. The discrimination and interpretation of such waves is possible in virtually the entire range of studied depths for seismic prospecting and petroleum exploration and also in deep seismic soundings. Each of these possibilities is illustrated in examples.
