摘要： The resonant frequency of an example transducer can be adjusted by changing the effective mass of a backing mass using a tuning module. The tuning module includes a electrical source, a switch, and an electromagnetic coil connected in series as an electrical circuit. The electromagnetic coil is mechanically attached to the backing mass, and is disposed within a reservoir of a magneto-rheological fluid enclosed within a casing. When the switch is closed, the electrical source applies a voltage and current to the electromagnetic coil, and induces a localized magnetic field within the magneto-rheological fluid. In response to this localized magnetic field, the magneto-rheological fluid increases in viscosity, assumes properties comparable to a viscoelastic solid, and become affixed to the electromagnetic coil. As the electromagnetic coil is mechanically attached to the backing mass, the solidified magneto-rheological fluid increases the effective mass of the backing mass. As a result, the resonant frequency of the transducer is altered.

摘要： Methods and systems for monitoring material loss in a downhole environment arising from corrosion and/or erosion include placing a downhole sensor in a borehole. The resistance of the downhole sensor is measured using a four-probe resistance technique in which a power source is provided at two electrodes of the downhole sensor and voltage is measured at two voltage taps. A rise in voltage over time indicates loss of conductive material on the downhole sensor. The conductive material on the downhole sensor may be formed to provide discrete voltage increases for improving reliability of material loss and/or rate of material loss resistance measurements.
