Epiroc introduces the DH350 drill rig: a step change in energy drills

The new single-piece substructure is a slingshot-style unit with integrated hydraulics to provide the fewest number of connections ever required for full rig up. The API monogrammed substructure offers a 27-1/2” split master bushing with a maximum table opening of 44”, which easily accommodates large diameter tools and complex bottom hole assemblies.

 

The powerful Epiroc-designed 1,200 HP diesel-hydraulic power unit provides unparalleled distribution of hydraulic power for all drilling functions, while enabling an unprecedented reduction in fuel consumption to easily get through the day. The stand-alone HPU minimizes cycle time between wells by eliminating the necessity of high voltage power from ancillary prime movers and remains an integral component atop the DH350 substructure when walking the rig between wellheads.

The crownless telescopic mast featuring 54” Nylatron sheaves provides 350,000 lb. of pullback, 50,000 lb. of pulldown force through the robust tip-out hydraulic top drive. The twin spur gear powerhead offers variable speed electric over hydraulic control with a maximum 30,000 ft-lb of rotary torque, and the ability to handle single joints of Range III drill collars up to 8” inches in diameter. The top drive delivers substantial improvements to operator safety and offering the highest quality pipe handling when coupled with the integrated iron roughneck and remote operated catwalk.

The optimized load configuration and integrated hydraulics allow crane-free rig up in under 12 hours with as few as six (6) rig loads between drilling locations, allowing operators to minimize cycle time and improve long-term well economics. The minimized load configuration is accomplished through a combination of streamlined skid-mounted components and single-piece assemblies transported via purpose built trailer or integrated subassembly axle groups. DH350 offers multiple premium configurations including hands-free BOP handling, and is currently available for order.

 - “We will continue to drive the paradigm shift in conventional rig design - the DH350, a step change in drilling efficiency.”
