Abstract
A system, apparatus and method for determining an acoustic property of a fluid in a wellbore is disclosed. A faceplate is placed in the wellbore with a stepped surface of the faceplate in contact with the fluid. The stepped surface includes a non-stepped face and a stepped face. A first portion of an acoustic pulse passes from the faceplate into the fluid via the non-stepped face and a second portion of the acoustic pulse passes from the faceplate into the fluid via the stepped face. A first reflected acoustic pulse related to the first portion of the acoustic pulse is received. A second reflected acoustic pulse related to the second portion of the acoustic pulse is received. A measurement of the first reflected acoustic pulse and a measurement of the second reflected pulse are used to determine the acoustic property of the fluid in the wellbore.
