claims pending in the application. Claims 1-6, 8-9 and 17-18
have been canceled.
Appellants’ invention is directed to a method for
performing sonic logging while drilling a borehole traversing an
earth formation. Claim 7 is illustrative of the claims on appeal
and recites:
7. A method for performing sonic logging while
drilling a borehole traversing an earth formation, including
drilling the borehole with a drill string having a drill bit at
its lower end and drilling fluid in the borehole surrounding the
drill string, the steps of said method comprising:
a) drilling with a drill collar incorporated into the
drill string;
b) transmitting, from a location on said drill collar,
acoustic energy into the surrounding earth formations;
c) receiving, at a location on said drill collar,
acoustic energy returned from the surrounding earth formations;
d) providing at least one output related to the
received acoustic energy, said at least one output comprising a
plurality of waveforms; and
e) processing said at least one output to determine at
least one characteristic of said earth formations, said
processing comprising summing said plurality of waveforms to
obtain a resultant stacked waveform.
