SPATIALLY FILTERING FORMATION AND CHANNEL ECHO SIGNALS

摘要

A method and apparatus for spatially filtering a signal set to enhance interface echoes representing a borehole (111) configuration. The spatial filtering technique provides information regarding th e various interfaces (123, 125, 127) formed between materials in the borehole environment, as well as thicknesses of the various mat erials present in the borehole. Further, the presence of channels (129) formed during the cementing procedure are detected.
