A method (60) of determining core orientation of a core sample (12) cut from the ground by a drill rig (10) having a drill string and a drill bit (20) coupled to a downhole end of the drill string. Drilling data (Cn, Rn) is continuously acquired while the drill rig (10) is operating to cut and retrieve the core sample (12). The drilling data is a combination of core orientation data Cn and rig operational data Rn, where the rig operational data is constituted by either one or both of: (a) near bit rig data Nn; and, (b) at surface rig data Sn. The drilling data is analyzed for a specific pattern of rig operational data Rn indicative of the core sample being broken from ground by operation of the drill rig (10). On detection of the specific pattern, the orientation of the core sample prior to being broken from the ground is the acquired core orientation data Cn coinciding with that specific pattern of rig operational data Rn.

Abrégé

An overshot (10) comprises a latching mechanism (12) for latching a member such as a spear point (14); and, an actuator (16) which actuates the latching mechanism (12). The latching mechanism (12) has a number of different operational states. One of these is a neutral state in which latching mechanism (12) is able to latch or capture a spear point (14). In the neutral state, latching mechanism (12) is able to open in order to receive spear point (14) and then self- close to latch or retain the spear point (14). Latching mechanism (12) also has a locked state in which it is locked in a closed position by actuator (16) to prevent the release of a latched spear point (14). The third state is the release state where the overshot is locked in an open position by actuator (16) to release a previously latched spear point (14). The actuator (16) operates as a linear to rotary motion converter which converts linear motion of one part of the actuator to a rotary motion of another part of the actuator between a plurality of rotationally spaced positions. The rotational positions determine the state of the latching mechanism.

A latching system has a latch body, a latch carrier and two latch dogs. The latch dogs are retained in the latch carrier by two pins. The latch carrier is located within the latch body. The latch body has slots through which the latch dogs can extend. The pins pass through both latch dogs and through longitudinal slots in the latch carrier. The pins are fixed at their opposite ends to the latch body. When the latch carrier is moved axially the latch dogs move parallel to each other between: a latching position where the latch dogs extend from the latch body and latch carrier and can engage a latching mechanism; and a release position where the latch dogs retract inwardly.
