Hydraulic Work Over (HWO)

Balance Point Control offer a wide range of Hydraulic Workover services for the European Market. From our establishments in Emmen (NL) and Aberdeen (UK) we closely coordinate our operations both onshore and offshore. Our HWO units are designed according the highest standards and incorporate the latest technology and safety systems. Many years of experience, continuous focus on quality, flexibility and tailor-made solutions contribute greatly to the success of our operations.

Hydraulic Workover is a versatile, cost saving and safe technique for repair- and remedial work on all types of wells.

HWO Units

Why HWO?

Hydraulic Workover is a well intervention technique which can be used to install or remove tubular in- or out of dead wells. "Dead" well means that the well has zero surface pressure and has a heavy fluid or mud in the wellbore, or is not capable of sustaining natural flow.

A HWO unit can cover the same working envelope as a workover rig but has advantages over conventional rigs or hoists for certain applications, such as:
 
  • •  Small and flexible footprint
  • •  Small environmental impact
  • •  It is quickly and easily mobilized to offshore platforms
  • •  It is quickly and easily mobilized to remote land wells
  • •  Costs efficient
  • •  Perfect control over the workstring (tubular) 
  • •  Custom Rig-up configuration / Modular approach
 
 
 
 
Hydraulic CylindersHydraulic Power
 
The HWO unit (Hydraulic Workover Unit) utilizes hydraulic cylinders to lift the tubular in- or out of the well. The use of hydraulic cylinders allows perfect control over tubular movements and eliminates the use of a large mast construction which is present on conventional drilling rigs.
 
 
Hydraulic cylinders can generate large pull and push forces and give the HWO unit a small footprint and layout. These properties are especially beneficial for offshore operations where space is limited and where weather conditions can be harsh. In general is the running speed of a HWO unit lower than that of conventional workover rig.
