The   Acoustic    Televiewer    takes    an    oriented    "picture"    of    the borehole    using    high-resolution    sound    waves.    This    acoustic picture   is   displayed   in   both   amplitude   and   travel   time.   This information   is   used   to   detect   bedding   planes,   fractures,   and other   hole   anomalies   without   the   need   to   have   clear   fluid   filling the    boreholes.    The    televiewer    digitizes    256    measurements around   the   borehole   at   each   high-resolution   sample   interval (.005    meters/.02    feet).    This    data    is    oriented    to    North    and displayed   real-time   while   logging   using   the   Visual   Compu-Log software.   Analysis   includes   color   adjustment,   fracture   dip   and strike   determination,   and   classification   of   anomaly.   It   allows information   to   be   displayed   on   the   graphical   screen,   plot,   and in   report   format.      Optionally,   the   tool   can   be   equipped   with   a natural gamma sensor.
