Abstract
An apparatus for transmitting and/or receiving energy in a borehole penetrating a subsurface formation includes a tubular assembly having a tubing mandrel and a sleeve at least partially surrounding a circumference of the tubing mandrel, wherein the tubing mandrel includes a cavity and the sleeve defines at least a portion of an opening over the cavity. The apparatus also includes a transducer assembly disposed in the cavity and configured for transmitting and/or receiving the energy, wherein the transducer assembly upon relative movement of the tubing mandrel with respect to the sleeve is displaced radially.
Claims19
An apparatus for transmitting and/or receiving energy in a borehole penetrating a subsurface formation, the apparatus comprising:
- a tubular assembly comprising a tubing mandrel and a sleeve at least partially surrounding a circumference of the tubing mandrel, wherein the tubing mandrel comprises a cavity and the sleeve defines at least a portion of an opening over the cavity;
- and
- a transducer assembly disposed in the cavity and configured for transmitting and/or receiving the energy, wherein the transducer assembly upon relative movement of the tubing mandrel with respect to the sleeve is displaced radially outward such that at least a portion of the transducer assembly extends outside of the sleeve.
A method for transmitting and/or receiving energy in a borehole penetrating a subsurface formation, the method comprising:
- conveying a tubular assembly through the borehole, the tubular assembly comprising a tubing mandrel and a sleeve at least partially surrounding a circumference of the tubing mandrel, wherein the tubing mandrel comprises a cavity and the sleeve defines at least a portion of an opening over the cavity, wherein a transducer assembly is disposed in the cavity and configured for transmitting and/or receiving the energy, and wherein the transducer assembly upon relative movement of the tubing mandrel with respect to the sleeve is displaced radially outward such that at least a portion of the transducer assembly extends outside of the sleeve:
- stopping a conveyance of the sleeve in the borehole at a selected location while the tubing mandrel proceeds downhole;
- said displacing the transducer assembly radially through the opening due to the relative movement of the tubing mandrel with respect to the sleeve;
- and
- transmitting and/or receiving the energy using the displaced transducer assembly.
