摘要： A well casing is insonified with a first acoustic wave in a first mode that may be any mode of a set including: extensional mode, thickness mode, flexural mode. A first echo is received at a first acoustic transducer for receiving, a first signal is produced and a first measurement is extracted from the first signal. The casing is then insonified with a second acoustic wave in a second mode that may be any mode of the set of modes but is distinct from the first mode. A second echo is received at a selected second acoustic transducer for receiving and a second signal is produced. A second measurement is extracted from the second signal. The zone behind the casing of the well is evaluated from a combination of the first measurement and the second measurement.

摘要： A method for estimating an impedance of a material behind a casing wall in a borehole, the method comprises exciting (602) the casing wall with an acoustic pulse, and measuring (603) an experimental acoustic waveform (W) reflected from the casing wall. The method further comprises initializing (600) an impedance parameter (Zin), computing (601) an inverse casing response (Rcas−1) as function of the impedance parameter, and deconvoluting (604) the experimental acoustic waveform with the inverse casing response to obtain a transducer (T). An iterative loop (605, 606, 607) is performed, comprising the computing of an inverse casing response and the deconvoluting of the experimental acoustic waveform by varying (607) the impedance parameter until the transducer response becomes compact (605, 606) in the time domain. The estimated impedance (Zcem) is obtained (606) from the impedance parameter when the transducer response is compact.

摘要： A method to obtain gain-corrected measurements. A measurement tool having one or more arrays is provided, wherein the arrays include two co-located triaxial transmitters and two co-located triaxial receivers. Measurements are obtained using the transmitters and the receivers. Impedance matrices are formed from the obtained measurements and the impedance matrices are combined to provide gain-corrected measurements. The apparatus may alternatively be a while-drilling logging tool having one or more arrays, wherein each array comprises a transmitter, a receiver, and a buck, and wherein the signal received by the receiver is subtracted from the signal received by the buck or vice versa. A slotted shield may be incorporated into either embodiment of the tool. The slots may form one or more island elements. A material is disposed in the slots. The islands and shield body have complementary tapered sides that confine the islands within the shield body.

摘要： A surface seismic survey is generated or obtained from Earth's surface and is based on time in which acoustic waves are reflected to Earth's surface. One or more tools measure density and sonic velocity of a subsurface formation. An estimate of acoustic impedance is obtained from the density and the sonic velocity to generate a synthetic seismic survey. The synthetic seismic survey and the surface seismic survey are compared and/or correlated. The acoustic impedance can be iteratively estimated until the synthetic seismic survey matches the surface seismic survey. Matching the surface seismic survey with the synthetic seismic survey may ensure that the surface seismic survey may be calibrated in actual depth.
