Automated Hydraulic Rigs
The HH Series Rigs range from 165,000 lbs (75 metric tons) to 600,000 lbs (272 metric tons) of static hook load capacity,
which translates into a drilling capacity of wells up to 15,000 ft depth, depending on the well design and its casing profile.
This covers over 90% of all oil and gas or geothermal wells drilled on land worldwide.
HH Series are multipurpose drilling rigs available in various configurations, including manual, semiautomatic and automatic, for both drilling and workover operations.
The HH Series Rigs do not have a conventional mast structure, nor drawworks, long wires or travelling equipment; these are replaced by a powerful hydraulic cylinder, which is the main hoisting element of the rig.
It is a self-standing telescopic mast with reduced height and reduced dropped objects.
Compared with rigs of equal power and capability, the HH Series Rigs create a smaller footprint reducing environmental impact, making riggingup a simpler task.
Major rig components are permanently mounted to semi-trailers for fast rig-up or down for transportation between drill sites.
Enhanced Performance.
The HH Series Rigs are designed to achieve high levels of safety and outstanding performance.
They integrate various hydraulic equipment in a drilling process that is largely automated and where all the drilling functions are centrally controlled from the driller’s cabin.
An advanced automation concept allows performance for most of the routine drilling operations, including tripping in and out the drill string and tubulars, with minimal manpower needed on the rig floor.
Therefore only a reduced drilling crew is needed to operate the rig; it is a “hands off” operation, where nobody is exposed to direct contact with rotating tubulars, tongs and wrenches or falling objects.
The length of time of each repetitive activity becomes regular, predictable and sustainable, mostly because it is less affected or conditioned by human behaviour, attention or tiredness of the rig crew.
Tripping in and out is done almost entirely automatically, without depending on manual labour and regardless of weather conditions or time of day or night.
