ABSTRACT:
Continuity of subsurface formations or beds in the earth between existing wells is investigated. Seismic energy is sent from a seismic source in one of the wells at various selected fixed depths. A number of sensing geophones deployed at selected fixed depths in one or more adjacent wells detect the seismic energy as data. A frequency domain decomposition process is performed on the data in order to determine if any of the formations located between the wells function as waveguides for seismic energy within the frequencies of interest. Those formations exhibiting waveguide properties are indicated as continuous between the wells.
