Abstract
Systems and methods for cement evaluation by determining a shear velocity of a shear wave () propagating within a medium () located between a formation () and a casing () in a borehole () are presented. The method can include positioning an ultrasonic transducer array () in the borehole inside the casing. The method can also include in a pushing mode, generating a shear wave in the medium with the ultrasonic transducer array inside the casing. The method can also include in an interrogation mode, measuring a shear velocity of the shear wave in the medium with the ultrasonic transducer array. The shear velocity may be used to determine whether the medium is solid or liquid.
