Devices, systems, and methods for retrieving inner tubes following core sampling are disclosed. Exemplary systems include a drill rig having a drilling axis. The drill rig can have a mast having a longitudinal axis and opposed first and second ends, the first end of the mast being configured for positioning proximate a drilling formation. A drill head can be configured to impart rotation to a drill string. The drill head can be configured for movement about and between a first position in which the drilling axis extends through the drill head; and a second position in which drill head is spaced from the drilling axis.

Devices, systems, and methods for retrieving inner tubes

A core tube handling device can be used with exploratory drilling rigs. The device can include a slew arm mounted on the rig's mast and a pivot arm mounted on the slew arm. When the slew arm is adjacent to the mast, clamping devices on the pivot arm can grasp and hold a core tube from the drill string. The slew arm can pivot away from the mast and align the pivot arm with a tray that receives and holds the tubes. The pivot arm can pivot to a position proximate the tray and release the tube. The tray can be rotatable and translatable to facilitate transfer of the tube from the pivot arm to the tray.

Core tube handling device

A wireline system for use during drilling operations. The wireline system has a wireline assembly and a roller assembly. Both the wireline assembly and the roller assembly are positioned within a front portion of a drill rig.

Wireline system and methods of using same

A wireline system for use during drilling operations. The wireline system has a wireline assembly and a roller assembly. Both the wireline assembly and the roller assembly are positioned within a front portion of a drill rig. Described herein, in one aspect, is a wireline system for use on a drill rig. The drill rig can comprise a drilling system, and the drilling system can comprise a mast, a drill string, and a drill head configured to impart rotation to the drill string within a drilling formation.
