2 OVERVIEW Preamble What Are The Industry s Requirements? FracHOOK TM System Technical Features And Benefits FracHOOK TM System Economical Benefits FracHOOK TM System Main Components FracHOOK TM System - Example Of A Well Configuration FracHOOK TM System - Specifications 2

3 PREAMBLE Efficient oil and gas production from tight formations requires drilling horizontal wells Multi-stage fracturing techniques increase production from low permeability reservoirs Multilateral completion systems with multi-stage fracturing capabilities maximize the economical reserve recovery from tight formations 3

4 What are the industry s requirements? Increased Reservoir Interface Reduced CAPEX Maximize Surface Potential Field Proven Equipment Access To All Laterals Maintain Current Fracturing Techniques Maintain Back-to-Back Frac Schedule Threaded Pipe or Coil Tubing Live Deployment of Frac Diverters Future Re-Frac Capability 10,000 PSI (69 MPa) Pressure Differential Rating 4

5 Technical Features And Benefits: 10,000 PSI (69 MPa) Pressure Differential Laterals can be completed with the Frac-Point TM Open Hole Fracturing System or with cemented liners Multilateral equipment installed during the drilling phase, before any stimulation / treating is done Fracturing of both laterals is done with one mobilization of frac equipment, and without the need for drilling rig on location Full ID access to each lateral, enabling the ability to complete fracturing on the fly or stage fracturing using the frac plug method Comingled or separate production systems available 5

6 Technical Features And Benefits (continued): Coiled or coupled tubing deployed diverter system ensures pressure isolation and positive re-entry access into each lateral Future re-frac capability Hydraulic-Set Open Hole Packers or Reactive Element Packers options available Single-Acting or Multiple-Acting (Re-Closeable) Frac Sleeves options available Frac sleeves with integrated inflow balancing capability ( Equalizer TM FP ) option available, for preventing early water or gas break through 6

7 Economical Benefits Vs. Single Wells: Increased reservoir interface Increased reserve base per well Access to small reserves, otherwise uneconomical to drill Reduced CAPEX Surface location Casing Cementing Wellhead equipment Pipeline 7

8 Economical Benefits Vs. Single Wells: (continued) One rig mobilization to drill the ML well One mobilization of frac equipment for fracturing both laterals, without the need for the drilling rig on location Reduced environmental impact 8

9 FracHOOK TM SYSTEM MAIN COMPONENTS The HOOK TM Hanger System is at the heart of the FracHOOK TM A HOOK TM Hanger System is a device used to provide: Mechanical support at the junction Positive access to all laterals Unlimited access thru multiple junctions Commingled production Selective production Selective isolation capability 9

10 FracHOOK TM SYSTEM - MAIN COMPONENTS The HOOK TM Hanger System is at the heart of the FracHOOK TM SYSTEM is the key word: The HOOK TM Hanger is designed around the WindowMaster TM Casing Exit System Selective access to all laterals and pressure integrity for fracturing operations are obtained using a set of diverters Lateral Re-Entry Diverter (O-Ring Style) Lateral Frac Diverter (Bullet Seals Style) Main Bore Frac Diverter (Bullet Seals Style) Main Bore Diverter Deflector 10
