Coil Well Service

Essential Coil Well Service ("ECWS") operates the largest coil tubing well service fleet in Canada providing coil services to producers in the Western Canadian Sedimentary Basin. With strategically and conveniently located bases, ECWS effectively provides complete services to areas such as the Horn River, Montney, Cardium, Viking, Oilsands, SAGD, Lower Shaunovan, and Bakken, furthering its commitment to its customers. The new Generation III and IV masted deep coil tubing rigs are well-suited to complete longer, deeper and more complex wells.

Leading the coil industry in safety standards, and equipment innovation, ECWS specializes in safe, efficient, and economical well interventions. ECWS' new generation of advanced coil tubing technology has enabled it to provide coil tubing rigs that are designed for rapid deployment and efficiency – with a strong focus on safety

Director, Essential Coil Well Service

Mr. Nowell began his career with Technicoil in 2001 and transitioned to Essential in 2011.

Deep Coil Tubing

Generation II:

  • Gen II was the first masted coil tubing rig built on a trailer for Essential
  • Improved reel capacity compared to Gen I
  • The built-in mast eliminates the need for a crane, reducing rig up time

 

Generation III:

  • Design is similar to Gen II but the unit is bigger and heavier
  • Bigger reel sizes for an increased reel capacity
  • Built with hydraulic legs that can raise the height of the injector

Generation IV:

  • Impressive reel capacity, carries larger and heavier coil compared to the Gen II and III
  • Patented sliding mast system to increase mast height
  • Walking and pivoting feature designed for pad work, first in the industry
  • Unique injector guide with a rack and pinion positioning system to move the injector

Special Features of the Generation IV Rigs:

Reel
  • Increased reel capacity for larger and heavier coil
  • Reel slide system for weight distribution

 

Mast/Injector
  • Increased mast height to allow for a larger bottom hole assembly and higher wellhead assembly
  • Patented hydraulic mast slide for even weight distribution
  • Injector guide with rack and pinion positioning system

 

Additional Design Features
  • Rig mounted instrumentation and electronic over hydraulic primary controls
  • Integrated hydraulic crab walking system to increase mobility on extremely tight locations and to decrease rig up time on pad well sites
  • Coil tubing injector can be operated in any position while maintaining well center without relocating the rig
  • The reel can move along the trailer; this distributes the weight more evenly between the truck's axis

 

Generation IV Reel Trailer
  • Developed to test the capability of the heavy duty trailer to carry the reel
  • Built with a reel slide system for weight distribution
  • Using a box frame trailer design and high tensile material, the reel can widen and increase the capacity to carry larger coil diameter or longer strings for milling

Conventional Deep:

  • Tractor/trailer coil tubing rigs
  • 10K rated pressure control equipment
  • 4,500m depth capacity utilizing 2" coil tubing
  • 45 ton crane available with all rigs

 

 

Essential also provides coil tubing rigs specific to the shallow and intermediate market.

Single Pumper (600 HP) Triplex Pump

Twin Pumpers (x600 HP) Triplex Pump

Twin 1,000 HP Quintplex Pumps with Matched Engine Packages

 

Chemical Addition Unit

  • 6 tote (7,200 litre) capacity, holds all the coil supporting chemicals for an entire job
  • Chemicals are loaded to the fluid pumper using an injection system, which reduces the chance of spill on location
  • 2 - SPX Waukesha electric driven pumps and 4 - Eagle progressive cavity electric driven pumps
  • Dycor Smart Vue Operating System in a fully enclosed and climate controlled cab
  • Large lab area complete with all necessary equipment for complete fluid analysis
  • E&H coriolis flowmeter systems for accurate chemical additions for coil tubing operations
  • 40 kw generator to supply power for chemical pumps, heating systems, lighting, laboratory, heated chemical hoses, control systems and data acquisition systems

 

 

Coil Support Chemicals


  • Friction Reducer – Reduces pumping fluid friction
  • Gel Sweep –  Lifts cuttings when milling
  • Coil Lube – Metal to metal lubricator
  • Foamers – Carries sand & debris out with less hydrostatic pressure
  • Biocide –  Anti-fouling agent
  • Stress Crack Inhibitor – Reduces risk of embrittlement and stress cracking on metal pipe
  • H2S Scavenger – Treating sour fluids

Nitrogen Pumpers

Tri-drive, body mounted, nitrogen flameless pumping units
  • Glycol, hydraulic, and exhaust vaporization systems
  • Mounted N2 tanks that hold 7,000 scm of useable nitrogen gas
  • Pump rates from 5 scm – 85 scm per minute
  • Pump pressures from 0 – 70 mpa (0 – 10,000 Psi)
  • Pump temperatures from -5 degrees C to 70 degrees C (23 F to 158 F)
