ABSTRACT: This technical note presents three scales of drilling infrastructure for comparison. These three methods include: (1) a small hand-drill designed for retrieving cores down to ca. 5 m depth, (2) the medium-scale UNIS Permafrost Drill Rig (down to ca. 50 m depth), and (3) an industrial drill rig designed for coring to depths of greater than 1 km. All methods vary with respect to maximum drill depth, operational cost, and ease of transport throughout the landscape.

RÉSUMÉ: Cet article compare trois méthodes de forage de tailles différentes. Ces trois méthodes correspondent à: (1) une petite foreuse portative conçue pour récupérer des carottes allant jusqu'à 5 m de profondeur, (2) une foreuse de taille moyenne UNIS Permafrost Drill Rig (jusqu'à environ 50 m de profondeur) et (3) une grosse foreuse industrielle conçue pour forer à des profondeurs de plus km. Les méthodes de forage varient en fonction de la profondeur maximale des forages, des coûts d'exploitation, ainsi que de la facilité de leur transport sur le terrain.
