Abstract:
1. A method of logging an earth formation comprising: (a) conveying a logging tool into a borehole in the earth formation and rotating the tool therein; (b) acquiring a plurality of measurements of a parameter of interest of the earth formation during rotation of the tool, wherein said plurality of measurements are acquired with a plurality of sensors; (c) determining a time separation value from said plurality of measurements associated with separate sensors for a feature of the earth formation; (d) determining an incremental depth for the feature of the earth formation from the time separation value and an offset distance between said plurality of sensors to obtain the feature of the earth formation in incremental depth; (e) determining a geometry attribute of the subsurface feature of the earth formation in incremental depth relative to the borehole; and (f) displaying the feature of the earth formation.
