The DR24 drills and cases simultaneously — the defining advantage of the dual-rotary system. For difficult formations, large-diameter wells, and deep geothermal, it is the rig that others cannot match.
DR24 standard configuration. Exact specs vary by year and build options.
Why the DR24 commands a premium — and earns it back on every difficult job.
The DR24's lower casing drive rotates and advances casing as the top head drills ahead. The bore is protected from collapse at every inch of depth.
Gravel, cobbles, loose alluvium — formations where a conventional rotary would collapse the bore are routine for the DR24.
Casing jaw sets from 6" to 24" standard. No other truck-mounted rig in its class handles 24" casing as efficiently.
Drilling and casing in one pass eliminates the second mobilisation for casing installation — saving days on larger-diameter wells.
A well-equipped DR24 comes with hammers from 6" to QL120 (12"), multiple jaws and clamps per size, discharge swivels, and drill rod in multiple diameters.
The dual-rotary market is thinner than single-rotary — which keeps values high. A low-hours DR24 is a generational asset.
High-volume supply wells in unstable geology — where conventional rotary cannot maintain the bore.
Large-diameter geothermal bores for utility and district heating — where 16–24" casing is standard.
Large-bore monitoring wells, remediation installations, and aquifer testing.
Deep high-capacity irrigation wells in challenging alluvial and cobble formations.
Large-diameter dewatering wells at open-cut mines — fast completion and large casing ID for high pumping rates.
Development projects in Africa, Asia, and the Middle East — where large-community water supply wells need the dual-rotary system.
