Definition of the SystemDefinition of the System
The FLATpaktm Umbilical is a uniquely designed multiple
conduit bundle that …
� Was originally designed for CONVEYING Hydraulic Subsurface
Pumps
� Provides a hydraulic circuit for POWERING these pumps
� Provides a PRODUCTION CONDUIT for producing the well
� Installed by conventional Coiled Tubing Units
� Utilizes complete Canadian Class 1+2 “safe operating” practices
� Used for deployment of Subsurface Hydraulic Pumps, Electric
Submersible Pump, gas lift & other Artificial Lift systems
Advantages of FLATpakAdvantages of FLATpaktmtm UmbilicalUmbilical
The FLATpaktm Umbilical…
� Utilizes conventional Coiled Tubing for conduit(s)
� Replaces Jointed Production Tubing and rods
� Eliminates “Conventional Rig” for installation
� Combines multiple services into one.
� Field-proven “connectors” available for terminations
� Variable components offer design and function flexibility
� Successful applications with a variety of components

3-Line HSP Service Pump for CBM wells Alberta-total 100+ wells same FLATpak
◦ 1-Line provides Production Conduit for produced water to surface from pump discharge
◦ 2-Lines provide closed-loop hydraulic circuit
◦ Use of this system reduces fluids and additional pressure placed on reservoir during operation for cleanout
◦ Results in a non-invasive treatment
◦ Ideal means to test HSP
◦ Cost effective/no CAPEX
◦ (2) CTUs currently in service

Recent Issues & OpportunityRecent Issues & Opportunity
•Gas migration / explosive decompression
entering downhole “encapsulation end”
•Depth limitations related to potential damage to
encapsulation by CT Injector Head Gripper Blocs
Recent Issues & OpportunityRecent Issues & Opportunity
SOLUTION…Gas Migration / Explosive Decompression
•Addition of “underlayer” of
Polyethylene Polymer from
Innotek “G-19”
•Preliminary trials prove
advantageous by improving
adhesion of tube to encapsulation

Recent Issues & OpportunityRecent Issues & Opportunity
SOLUTION… Depth limitations related to potential damage to encapsulation by CT Injector Head
•Increased surface area results in decreased “skate”
hydraulic pressure•Newly designed “drive arch” system results in
increased surface area and decreased “skate”pressure resulting in ability to “run deeper” with out
potential damage to encapsulation
FLATpakFLATpak’’s Benefitss Benefits
Superior Design• Minimizes formation damage due to live well intervention• Provides mechanical and corrosion protection and insulation from extreme
temperatures• Easily repaired in the field• Optional selections of tubing or wire proven they can be spooled• Least cost manufacturing via rectangular shape matrix
Versatility• Facilitates permanent ALS installation and temporary service intervention• Configuration can be easily altered for specific applications• Is conveyed with any conventional CT unit
Efficiency• Permits intervention consolidation (ie: Coiled tubing unit replaces service rigs,
capillary rigs & cable spool rigs)• Facilitates swift and efficient operations in a CT environment with minimal
surface disturbance
Safety• Offers multiple points of well control
