The    Full    Wave    Sonic    tool    contains    a    single transmitter     and     dual     receiver     to     record formation   travel   times.   The   full   wave   form   data is    also    recorded    simultaneously,    along    with near      and      far      travel      times,      borehole- compensated     delta     time,     calculated     sonic porosity,    receiver    gains,    near/far    amplitudes and   natural   gamma.   The   sonic   or   acoustic   log uses     the     basic     principle     of     sound     waves traveling   through   a   media.   The   Century   sonic system    uses    a    single    transmitter    and    dual receiver   system   for   recording   the   travel   times of    the    formation.       The    receivers    are    spaced      approximately     3     and     5     feet,          from     the transmitter.
