Abstract
A core barrel capacity gauge for use on a core barrel assembly having a barrel for receiving a core sample. The core barrel capacity gauge includes a core sample marker located within the barrel such that the core sample marker rests against the top of the drilled core sample and a marker location sensor. The marker location sensor is arranged to detect the location of the core sample marker within the barrel.
Claims20
A core barrel capacity gauge for use on a core barrel assembly having a barrel for receiving a core sample, the core barrel capacity gauge comprising:
- a core sample marker located within the barrel such that the core sample marker is adjacent a drilled core sample, the core sample marker including a signal generator that transmits a signal indicative of a position of the core sample marker relative to the barrel, and
- a marker location sensor including a receiver to receive the signal from the core sample marker.
A core barrel capacity gauge for use on a core barrel assembly having a barrel for receiving a core sample, the core barrel capacity gauge comprising:
- a core sample marker located within the barrel such that the core sample marker rests against a top of a drilled core sample, and
- a marker location sensor arranged to detect a position of the core sample marker within the barrel,
- wherein the core sample marker includes a magnetic field sensor and the barrel includes a plurality of magnets along the length thereof, such that when the core sample marker passes one of said magnets, the magnetic field sensor detects the presence of that marker and generates said signal to be received by the marker location sensor.
A core barrel capacity gauge for use on a core barrel assembly having a barrel for receiving a core sample, the core barrel capacity gauge comprising:
- a core sample marker in the barrel and adapted to rests against a top of a drilled core sample, the core sample marker including a signal generator that transmits a signal indicative of a position of the core sample marker relative to the barrel, and
- a marker location sensor including a receiver to receive the signal transmitted from the core sample marker.
A core barrel capacity gauge for use on a core barrel assembly having a barrel for receiving a core sample, the core barrel capacity gauge comprising:
- a core sample marker in the barrel and adapted to rest against a top of a drilled core sample, and
- a marker location sensor arranged to detect a position of the core sample marker within the barrel,
- wherein the position sensor includes a magnetic sensor and the position markers include magnets arranged at predetermined locations along a length of the barrel.
A method for detecting a position of a core sample within a core barrel assembly comprising:
- receiving at least one core sample in a barrel of the assembly;
- positioning a core sample marker in the barrel and on the at least one core sample in the barrel;
- the core sample marker in the barrel detecting a position of the core sample marker relative to the barrel;
- and
- using the detected position of the core sample marker relative to the barrel to determine a condition of the at least one core sample.
A core barrel capacity gauge for use on a core barrel assembly having a barrel for receiving a core sample, the core barrel capacity gauge comprising:
- a core sample marker in the barrel and adjacent a drilled core sample;
- markers arranged at intervals along a length of the barrel;
- a signal generator included with the core sample marker that transmits a signal as the core sample marker moves past each of the markers, wherein the signal indicates that the core sample marker is aligned with one of the markers and
- a marker location sensor including a receiver to receive the signal from the core sample marker.
