Patent ID: 6907348

Claim:
A method of determining a property of an earth formation using an acoustic logging tool on a bottomhole assembly (BHA) in a borehole in said earth formation, the method comprising: (a) using at least one transmitter in said acoustic logging tool for generating acoustic signals into said formation at a first depth of said BHA; (b) using a plurality of receivers on said logging tool for receiving acoustic signals, said plurality of receivers spaced apart axially from said at least one transmitter; (c) repeating (a) and (b) at least one additions depth of said BHA; (d) sorting said signals at said first depth and said at least one additional depth into at least one of (i) a common receiver gather, (ii) a common offset gather, and, (iii) a common-midpoint gather, giving re-sorted signals; and (e) processing said re-sorted signals to obtain an acoustic image oblique to the borehole axis.
