1. A method for treating a well, comprising:
hydraulically isolating an interval in a first well having a plurality of axially spaced apart intervals along the first well, each axially spaced apart interval having been fracture treated;
inducing a tube wave in the first well in the isolated interval;
detecting reflections in the first well from the induced tube wave;
determining hydraulic boundary condition and hydraulic conductivity of a fracture connected to the first well in the isolated interval using the detected reflections; and
performing a refracture treatment in the isolated interval when the hydraulic boundary condition and the hydraulic conductivity are within a predetermined range, wherein the performing a refracture treatment is performed while the isolated interval remains isolated.
