Abstract
A sonde and an apparatus for the deployment thereof against a well casing is described, the sonde comprising a resilient C-shaped member and at least one sensor.
Claims13
A sonde comprising a resilient C-shaped member and at least one sensor mounted thereto for deployment into a well, the member having an annular configuration with a single gap that defines two ends facing each other, the member being compressible, or having been compressed, to bring its ends closer together, wherein the sonde is for installation in or installed in a pipe and wherein the C-shaped member is clampable or clamped against the inner wall of the pipe.
A sonde comprising an expandable and/or resilient C-shaped member and at least one sensor mounted thereto for deployment into a well, the member having an annular configuration with a single gap that defines two ends facing each other, the member being compressible, or having been compressed, to bring its ends closer together, wherein a sensor is located at one of the ends.
An apparatus for deploying a sensor against a well casing, said apparatus comprising:
- a sonde, adapted to be lowered into a well, the sonde comprising a split annular member and at least one sensor mounted thereto for deployment into the well, the annular member being resilient and radially movable between a contracted and an expanded position;
- and
- a tool for releasably retaining the annular member in the contracted position so as to allow positioning of the sonde inside the well and subsequent deployment.
A method for deploying a sensor against a well casing, said method comprising:
- lowering a sonde into a well, the sonde comprising a split annular member and at least one sensor mounted thereto for deployment into the well, the annular member being resilient and radially movable between a contracted and an expanded position;
- and
- releasably retaining the annular member in the contracted position so as to allow positioning of the sonde inside the well and subsequent deployment.
