Patent ID: 8365839

Claim:
A device for collecting a sampled core from a formation, the device comprising: sampling tube sections adapted to being coupled together to form a sampling tube for containing the sampled core; a nozzle adapted for penetrating the formation and connected to a leading sampling tube section from among the sampling tube sections; a cylinder having a threaded end and a penetrating end opposite the threaded end; fins protruding outward from an external surface of the cylinder, not interfering with a translational movement of the device through the formation, and resisting a rotational movement of the nozzle once inside the formation; and auxiliary conduit sections adapted to being coupled together to form an auxiliary conduit along the sampling tube, the auxiliary conduit adapted for delivery of a fluid, wherein the auxiliary conduit is adapted to deliver the fluid to a borehole created by extraction of the device from the formation substantially simultaneously with the extraction of the device from the formation and creation of the borehole, wherein the auxiliary conduit includes a stopper for substantially preventing entry of soils and sediments into the auxiliary conduit during descent of the device into the formation, wherein the threaded end is adapted to be connected to the leading sampling tube section, and wherein the cylinder is adapted for receiving an O-ring, the O-ring adapted for deforming toward the sampled core, responsive to a compressive force resulting from a tightening of the threaded end to the leading sampling tube section.
