Abstract
A coring apparatus is provided, which apparatus, in one exemplary embodiment, includes a rotatable member coupled to a drill bit configured to drill a core from a formation, a substantially non-rotatable member in the rotatable member configured to receive the core from the formation, and a sensor configured to provide signals relating to rotation between the rotatable member and the substantially non-rotatable member during drilling of the core from the formation, and a circuit configured to process the signals from the sensor to estimate rotation between the rotatable member and the non-rotatable member.
Claims18
An apparatus for obtaining a core from a formation, comprising:
- an outer rotatable member coupled to a drill bit configured to drill the core from the formation;
- an inner member in the outer member configured to receive the core therein;
- and
- a sensor configured to provide signals for measuring rotation of the inner member when the rotating member is rotating to drill the core from the formation
A method of obtaining a core from a formation, comprising:
- rotating an outer member with a coring bit attached thereto to obtain the core from the formation;
- receiving the core in a substantially non-rotatable member disposed in the rotating outer member;
- and
- determining rotation of the substantially non-rotatable member using a sensor during rotation of the outer rotating member.
