Epiroc releases game-changing drill rig

Epiroc has introduced the DH350 oil and gas rig, which the company expects will deliver advanced performance for customers who want the best in an oil and gas machine.

The Epiroc DH350 is a 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 certified substructure offers a 27.5-inch split master bushing with a maximum table opening of 44 inches, which easily accommodates large diameter tools and complex bottom hole assemblies.

The rig is a powerful 1200 HP diesel-hydraulic power unit and provides unparalleled distraction of hydraulic power for all drilling functions, with reduced fuel consumption to get through the day.

The stand-alone HPU minimises 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.

In addition, the rig features a 54-inch Nylatron sheaves which 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 eight 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,” Epiroc outlined.

Epiroc has optimised load configuration and integrated hydraulics, allowing crane-free rig up in under 12 hours with as few as six rig loafs between drilling locations. As a result, operators minimise cycle time and improve longterm well economics.

Product manager for peephole oil and gas rigs Cole Carpenter said the DH350 combined the mobility of carrier drive rigs with the power density of conventional skidded systems to produce one of the most agile and capable drilling rigs in the market.

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