2 What is the FLATpak tm Why was it developed Advantages of using FLATpak tm What are the components How is FLATpak tm made Original Challenges What are the applications Where is FLATpak tm being Utilized and how New problems/solutions Agenda

3 The FLATpak tm 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 Definition of the System

4 The FLATpak tm 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 Advantages of FLATpak tm Umbilical

5 Carbon Steel Coiled Tubing High Strength 70/80k Grade, various gauges High Tensile Strength Outstanding low cycle fatigue Well understood mechanical and chemical properties External FBE Coatings enable use in mild H2S/CO2 environments for closed hydraulic systems Material Specifications
