Hydraulic Drilling Rigs

Everything about the HH Series is designed for speed, safety and efficiency. You can tell just by looking it is not a conventional rig.
From it selferecting telescopic mast made from a single powerful hydraulic cylinder to the built-in integrated hydraulic top drive, HH rigs are designed to optimize your drilling plan from top to bottom. Automated systems, centralized control and few rig floor workers combine for a safer and more efficient drilling operation, better performance and reduced costs. The HH Series drilling processes are largely automated and centrally operated from the climate controlled driller’s cabin. Stuck pipe becomes less of an issue with features that allow automatic drilling even with preset WOBs and ROPs or top drive back reaming.
One noticeable characteristic is the rig’s self-erecting telescopic mast composed of a single hydraulic cylinder that, although shorter than most conventional rigs, is capable of handling single stands of range 3 drill pipe. Perhaps the most noteworthy feature is the rig’s vertical pipe rack delivery system. The top drive is fully integrated with the vertical pipe rack through an automated pipe handler that rotates within the system. The top drive is equipped with a torque wrench for making up drill strings and has a horizontal displacement capability for moving pipe between the center hole and mouse hole. The pipe rack consists of a number of mobile bins with the pipe handler installed on a vertical rotating tower in the middle. Clamps grab the drill pipe from the bins and transfer them to the mouse hole according to your preset trip plan.

The semicircular pipe rack is assembled around the rig floor and contributes to quick rig-up and rig-down. And, in addition to a smaller crew on the rig floor during drilling operations, the pipe racks can be transported fully loaded with pipe reducing pipe handing procedures. Safety on the rig floor is also enhanced by the hydraulic power tongs stored in the fixed section of the mast.

The power tongs are completely operational from the driller’s cabin drilling console and connections can be made up or broken down without any manual intervention. With smaller crews and remote controlled operations, accidents on an HH Series drill site are dramatically reduced.

Compared with rigs of equal power and capability, the HH Series creates a smaller footprint reducing environmental impact and making rigging-up a simpler task. Major rig components are permanently mounted to semi-trailers for fast rig-up or down for transportation between drill sites. The HH Series answers many demands of the E&P industry; increased productivity, fewer accidents and a reduced impact on the environment. By automating tasks on the floor and mobilizing components for efficiency, the HH Series’ unique design is the shape of things to come.
