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

Multi Well Pad Design - WHY

4

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

Our Template – 2/3/4/5 Well Pads

5

- Wellhead, Wellhead stand, ESD

- Individual separators with 200 bbl water tanks

- SCADA Tower, PLC, Solar System

Well Head Design

6

- Standard Well head

- Standard wellhead height

- Spacing 10m between wellheads

Well Head Design

7

- 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

Automation and Communication

8

- Standard PLC control system

- Solar panels with battery boxes

- 40’ Mast to Company Network

Automation and Communication

9

- System can be controlled Remotely

- All devices are hard wired to PLC

Separator Design

10

- 600 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

- 200 BBL water tanks with integral

methanol tanks

Separator Design

11

- Proving taps

- 200 bbl water tank

- Water dumps directly to tank

- Condy dumps to pipeline

- Back pressure valve

Mounted low for maintenance

Separator Design

12

- Vertical separator

- Electric level switch's with

manual test button

- Electric level controllers

- Turbine meter for water

- Turbine meter for condy

Chemical Injection

13

- Pipeline Chemical

- Wellhead chemical

- Single pump for two sources

- Chemical tank is integral part

of water tank

- Tank Level Gauges Inside

Building

Reduce On Site Cycle Time

14

- Entire Well site facility can be pre built

- Separators prewired skid package

- Pipe rack modular with break flanges

Reduce On Site Cycle Time

15

- Platforms & Piping prebuilt

- Reduced travel time for workers to site

- Driving is one of the largest risks faced by our staff

Project Cost Efficiencies

16

- 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

Key Components to Design

17

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

The TAQA Template Our Learnings

18

- 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

Closing Thoughts – Multi Well Pad Design

19

- 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
