-
Deviated / Horizontal Well Optimization
Landing the pump at “full true vertical depth” can optimize productivity and recovery
Driving pumps with rod-less systems will reduce the number and cost of interventions and well downtime
-
Specific Applications Include:
• Shallow to deep well depths
• Low to medium pressure wells
• Slant, deviated and horizontal wells
• Natural gas, light oil, heavy oil wells
• Low to medium fluid rate wells
• Permanent production systems and well cleanout intervention
CJS Target Wells Challenged Well Population

Coiled Tubing (“CT”) Based Artificial Lift Deployment Technology
This CT based deployment technology consists of the following main components: • Pump System artificial lift prime
mover (Hydraulic/Electric) • Coiled tubing unit • Hydraulic or electric umbilical • Downhole pump (Reciprocating
pumps/PCP/ESP/Jet Pumps)
• Hydraulic & electric submersible motors
• Auxiliary lines for other services
(DH pressure gauge, chemical injection)

CT Artificial Lift Deployment Technology - ArmorPakTM Umbilical Is ...
• Umbilical coiled tubing (UCT) containing tubes to convey, actuate and receive production from downhole hydraulic & electric pumps
• A system that can include components to inject chemicals and receive downhole pressure and temperature data
• Is used to facilitate “rig-less” deployment of low maintenance artificial lift from conventional, unconventional, vertical, deviated and horizontal wells
• “Live well” deployment with ArmorPak to be available soon
• Used to install permanent production systems (ESP, HSP, HSPCP, JP) and to perform wellbore cleanouts (UCT Jet Pump Cleanouts)
• Conveyed using conventional coiled tubing units
• Patented and patent pending technology

CT Artificial Lift “Jet Pump” Deployment Technology / Well Cleanout Technology – “ArmorVak”
Operation Summary During the well cleanout operation, the jet pump is lowered into the well via the dual CT umbilical using one side of the ArmorPak to inject power fluid and the other side to commingle the power and produced fluids and solids returns to surface. System benefits: • Ideal for ultra low pressure well cleanouts • Permanent / semi permanent pumping operation available • Well servicing via conventional CTU • Operates in vertical, deviated and horizontal inclinations • Facilitates cost effective underbalanced cleanouts • Eliminates cost and requirement for nitrogen and surfactant • Reduced equipment mobilisation and associated cost • Suited for production, frac return and well liner cleanouts • Pioneered in Alberta in CBM & CHOP’s environments • Suited for solids production challenges • Copes with gas production through system • High flow velocities in coil • Process proven with Top Tier oil and gas operators
