Dual Rotary (DR). Both the Foremost DR 12 and DR 24 feature two rotary drives. The lower drive works independently of the top drive and feeds and rotates the casing. This allows us to advance steel casing through geological formations such as till, sand, gravel, and boulders.When the desired casing depth is obtained, the DR can continue to drill the open hole such as a conventional Top Drive unit. This method eliminates the need to trip out of holes or for tooling changes while going from casing advancement to open hole drilling.
