Intermediate Depth Drill

Description

The U.S. Intermediate Depth Drill (IDD) is the next generation of the Danish Hans-Tausen Drill and Danish Deep Drill, with the capability of producing 2-meter long cores. The IDD is sufficiently portable for coring at a wide variety of sites, and capable of retrieving 98 mm diameter core from the surface down to 1600 meters depth in two field seasons.

In addition to the drill itself, the IDD system includes the following ancillary items:

  • Core Processing System: core barrel puller, trays, vacuum, saw, and tables
  • Centrifuge to recover the drill fluid from the chips created by drilling the core
  • Drill fluid handling system
  • Vacuums to clean the drill cable and the core
  • Pilot hole system
  • A 4.9 m (16 ft) x 19.5 m (64 ft) x 2.8 m (9 ft) un-insulated Weatherport for housing the drilling and core processing operations

The IDD is designed and constructed to be transportable by Twin Otter or Bell 212 (or similar) helicopter. For field projects lasting more than one season, most equipment is left onsite to "winter-over". To drill to 1500 meters depth in two field seasons, a 10 person field-team for 24-hour per day drilling and core handling operations is required.
