FIELD: data processing.
SUBSTANCE: invention relates to geophysics and is intended for detecting boundary locations of multiple subsurface layers. Boundaries of subsurface layers in a subterranean region are identified based on measurements associated with multiple different transmitter-receiver spacings of resistivity logging instrument. First pair of subsurface boundary locations is determined based on a first measurement associated with a first transmitter-receiver spacing. Second, different pair of subsurface boundary locations is determined based on a second measurement associated with a second, longer transmitter-receiver spacing. First pair of subsurface boundary locations resides between second pair of subsurface boundary locations in subterranean region.
EFFECT: high accuracy for complex discontinuous structures and speed of obtaining information.
