Snubbing services
Precision Well Service Snubbing Services has a fleet of 12 truck mounted hydraulic rig assist snubbing units, 7 self-contained, free-standing snubbing units, rod snubbing services as well as freeze/hot tap service. Precision Well Service Snubbing Services is optimally positioned throughout the Western Canada Sedimentary Basin in locations close to both customers and support centers. The use of snubbing units allows operators in this area to enhance production and maximize the recoverable reserves from formations which are historically fluid-sensitive. Snubbing also works well in both over-pressured and under-pressured formations as well as low-permeability reservoirs.
Snubbing is ideal for underbalanced drilling programs and by facilitating string movement under pressure, ensures that an entire drilling operation can be conducted in a continuous, pressure-controlled environment to reduce the potential for formation damage. Other advantages of using Precision Well Service Snubbing Services and underbalanced drilling operations include:
- Boosting production by maintaining hydrostatic pressure below formation pressure
- Reducing chances of formation damage by eliminating use of "kill" fluids
- Protecting the environment by minimizing the chemicals in drill fluids and reducing wellsite flaring by re-circulating gas
- Preventing fluids and cuttings from invading the formation and causing damage
- Reducing the need for expensive reservoir stimulation treatments
- Allowing for formation evaluation operations during drilling
In addition to underbalanced drilling, snubbing is ideal for completions and workovers in fluid sensitive formations. Other applications include:
- Low-pressure gas wells that may not recover from overbalanced kill fluids
- High-volume, deep gas workovers where formation sandstone clays are susceptible to swelling
- Areas with high costs for purchase and disposal of kill fluids
A fully equipped snubbing unit can usually be quickly dispatched to a customer. Experienced snubbing operators plan the most efficient and safest approach to the often complex work with shallow and deep gas reservoirs in harsh terrain and conditions.
Precision Well Service Snubbing Services operates a fleet of rig assist snubbing units which work in conjunction with a service rig on the well site to lift the snubbing unit into place.
Precision Well Service Snubbing Services also markets stand-alone snubbing units that do not require a rig on site and improve efficiency and safety with an automated pipe-handling system. A cost-effective rig up procedure as well as minimal crew and vehicle needs and a small footprint on the wellsite are among the advantages of a stand alone snubbing unit.
