A contactless orientation system coupled with an inner core tube to one or more record carriers on or associated with a core sample held in the core tube having a longitudinal core axis and a core face accessible from an end of the inner core tube. An instrument guide is coupled to the end of the core tube from which the core face is accessible with an axis of the guide parallel to the core axis. Correlation information is generated between a rotational orientation of a known point P on the instrument guide about the guide axis and core orientation data known to the contactless orientation system. The instrument acts as the record carrier or generates the record carrier provided with the correlation information enabling orientation of the core sample to its in-situ orientation when released from the core tube.

A geologic core inspection table includes at least two legs, each including an extending portion for increasing the effective length of each leg, the extending portion at least partially concentrically disposed within or about the leg from which it extends; and a tabletop disposed above and coupled to the legs. The tabletop includes a top surface for receiving a core sample tray. At least one leg may be extended to a different height than at least one other leg.

A horizontal or deviated core sample is received from a wellbore. A presence of geologic indicators within the horizontal or deviated core sample is determined. The horizontal or deviated core sample is rotated to a position based on the presence and orientation of the geologic indicators. A top of the horizontal or deviated core sample is marked after the core has been rotated.

A software application for use on a mobile phone or other computerized hardware system for collecting geological core samples and assigning these samples to boxes is disclosed. The mobile application can include a scanner such as a bar code scanner for reading identifying data from boxes storing cores, and also provides the ability to print barcodes for identifying boxes of cores at a printer.

A geological core inspection system that includes a table to support core samples for inspection, a robotic geological core inspection system including a core sample sensing system to acquire sample inspection data (including an imaging sensor and a core sample position sensor), a core sample interaction system (including a dispensing system and a scoring system), and a robotic positioning system, and a control and communications system to provide for remote control of the core sample sensing system. The system further including a remote geological core inspection system to receive and communicate remote commands specifying requested operations of the robotic geological core inspection system (the control and communications system adapted to control operation of the core sample sensing system in response to the remote commands to perform the requested operations) and receive and present core data.

The long-reach drilling machine is for exploration drilling and core sample collecting and comprises a drill string comprising a variable number of hollow drill rods, a drill bit installed at a first end of the drill string, a ground-resting drill base for installation outside a borehole, a mast attached to the drill base, a drill head installed on and movable along the mast and to which a second end of the drill string is connected, the drill head rotating the drill string, a core tube movable within the drill string between a first position at the drill string first end for receiving a core sample and a second position at the drill string second end, an borehole core tube displacer capable of displacing the core tube between its first and second positions, and an external core tube displacer, distinct from the borehole core tube displacer, comprising a frame that is fixed relative to the drill string, a tube prehension device mounted to the frame and capable of traction on the core tube, and an actuator mounted to the frame and selectively actionable to activate the tube prehension device for allowing the core tube to be displaced relative to the frame beyond its second position.

Herein disclosed are apparatuses and methods related to coreflood testing apparatuses and methods for determining key physical properties of core specimens. More particularly, disclosed herein are coreflood inlet end-piece designs, coreflood testing systems and coreflood testing methods to enable simultaneous testing to obtain necessary data for determination for determining key physical properties of core specimens, which include the relative permeability and the capillary pressure, as well as, optionally the wettability of the core sample.

An interchangeable dismountable hinged box for storing core samples is provided that is particularly used in the field of the collection of mineral materials, deriving from geological exploration activities, for subsequent analysis. The interchangeable dismountable hinged box has modular walls that can be fitted interchangeably with a base allowing for the hinging of these walls between a parallel position and a position perpendicular to the base. The box has at least one storage compartment for core samples defined between two modular transversal walls and two modular longitudinal walls, and may contain additional storage compartments, obtained by interlocking interchangeable partitions with modular walls. The box is adaptable for meeting the need for storing core samples of varying diameters.
