FRACTURE EVALUATION THROUGH CASED BOREHOLES |
摘要 |
A method of estimating fractures in an earth formation includes: disposing an acoustic tool in a cased borehole in an earth formation, the acoustic tool including a multipole acoustic transmitter and an acoustic receiver; transmitting an acoustic signal into the borehole; measuring deep shear wave (DSW) signals generated from shear body waves reflected in the formation in a far-field region of the formation around the borehole; and estimating at least a location and an orientation of a fracture in the formation based on the DSW signals. |
