1 Multi Well Pad Facility Design Driving Efficiency & Process 1

2 Background Lance McKinnon P Eng. 20 Year Professional Engineer - Alberta, British Columbia Experience from Wellhead to Market - Gas Transmission (TransCanada Pipelines and Foothills Pipelines) - Gas Compression and Power Generation (Collicutt Energy Services) - Midstream (Keyera Energy) - Exploration and Production (Taqa North) Extracurricular Chairman of the Board of a Hockey Referee Group for Calgary Area with over 1700 members 2

3 About Taqa Canadian Unit headquartered in Calgary, AB Focus on Conventional O&G Business Highlights - 2P Reserves of >300mm bbl - Average Daily Production of > 75,000 bbl/d 3

4 Multi Well Pad Design - WHY Geological - Montney formations - Multiple pay zones - Technology - Using horizontal fracking methods to access pay zones - Scalability & Standardization - Common template for company - Ease of development with contractors - Efficiency - Cost - Time 4

5 Our Template 2/3/4/5 Well Pads - Wellhead, Wellhead stand, ESD - Individual separators with 200 bbl water tanks - SCADA Tower, PLC, Solar System 5

6 Well Head Design - Standard Well head - Standard wellhead height - Spacing 10m between wellheads 6

7 Well Head Design - Removable platform that bolts on to wellhead - Standard hydraulic ESD and wellhead transmitters - ESD Valve Mounted within 1 meter to isolate well during loss of containment from sand erosion 7

8 Automation and Communication - Standard PLC control system - Solar panels with battery boxes - 40 Mast to Company Network 8

9 Automation and Communication - System can be controlled Remotely - All devices are hard wired to PLC 9

10 Separator Design ANSI, threaded sweet Design - Three Phase separation, - Building for Cold Weather Design - High Level and Low Level Switches - Basket Strainers on condy and Water Legs BBL water tanks with integral methanol tanks 10

11 Separator Design - Proving taps bbl water tank - Water dumps directly to tank - Condy dumps to pipeline - Back pressure valve Mounted low for maintenance 11

12 Separator Design - Vertical separator - Electric level switch's with manual test button - Electric level controllers - Turbine meter for water - Turbine meter for condy 12

13 Chemical Injection - Pipeline Chemical - Wellhead chemical - Single pump for two sources - Chemical tank is integral part of water tank - Tank Level Gauges Inside Building 13

14 Reduce On Site Cycle Time - Entire Well site facility can be pre built - Separators prewired skid package - Pipe rack modular with break flanges 14

15 Reduce On Site Cycle Time - Platforms & Piping prebuilt - Reduced travel time for workers to site - Driving is one of the largest risks faced by our staff 15

16 Project Cost Efficiencies - Bulk purchase of materials - Engineering costs significant reduction - Fabrication to specification reduce/eliminate overtime - Work onsite - assembly, bolt up and pre commissioning - Repairs & Maintenance - One master set of parts applicable to all sites 16

17 Key Components to Design SAFETY A Safe Facility for Our Operations Team - Sand Probe Installed - ESD Mounted Close to Wellhead - Blast Tee s used between Well head and Separator - Keep it simple RELIABILITY A reliable Facility to keep production flowing - Heated and enclosed separator s and Utility buildings - Fully Automated - Facility is completely electronically controlled and can be controlled remotely 17

18 The TAQA Template Our Learnings - ESD Valve is Mounted within 1 meter to isolate well during loss of containment from sand erosion - Wellhead platform is removable to allow for service rig to move in and out quicker - Separators are designed as three phase with condy shipped in gathering line and water is tanked and trucked - rack design to allow for easy operability - Continual learning. Working toward a LEGO set for each well pad 18

19 Closing Thoughts Multi Well Pad Design - Better Risk Mitigation Standard build and operation of facilities - Standardization Plug & Play components - Cost Efficiencies Reduced cost per well - Cycle Time Less time onsite per well - Training Plug and Play personnel - Scalability Increase # of wells per location as required 19
