Labrador Shelf Significant Discoveries

Methods for Transportation

Gas gathering and transmission via pipeline. Volume reduction (liquefaction (LNG) or

compression (CNG)) followed by marine transportation.

Conversion to other products by changing from methane molecule (GTL) followed by marine transportation; and

Conversion to other energy forms such as electric power and transmission via subsea cable.

9

Production Volume verses Distance to Market

Pipeline LNG Carriers Production Volume CNG Carriers Distance to Market

10

Process Facilities

CNG is the most viable method of transporting gas from Labrador

The processing and conditioning will depend on CNG requirements ( most likely they will have the same as pipelines)

Requirements will depend on the flow rate, composition, temperature, and pressure of the produced gas and the components/impurities

11

Main Processing Considerations

Remove water vapor to avoid the hydrate formation and corrosion

Removal of solidsRemoval of gas condensate No H2S or CO2

Heating Required

12

Options Considered

Floating production storage offloading (FPSO) with CNG tankers;

Caisson / Island - CNG tanker; and Concrete gravity based structure (GBS)

- CNG shuttle tanker

13

Option 1: FPSO-CNG

Wells Drilled from separate MODU

14

Option 2: Caisson/Island-CNG

Erosion Protection

15

Option 3: GBS-CNG

16

Economic Analysis Assumptions

Field Size Base Case: 2.3 TCF (Bjarni North field) High: 5.0 TCF Low: 1.5 TCF

Price Base Case of $US 4.30 / MCF High: $US 5.45 / MCF Low: $US 3.20 / MCF.

Economic sensitivities Royalties: 5% & 10%, CAPEX: high and low models

Exploration risk assumed to be zero Operational down time assumed to be the same for all three

assessed options (100 days/year)

17

Economic Analysis - Results

FPSO – CNG gave most favorable economic based on: CashflowNPV discounted at 10% & 15% ATROR

GBS-CNG produced marginally more attractive economics vs. Caisson/Island-CNG

18

Economic Analysis - Findings

Only FPSO-CNG is feasible with gas prices of $US 5.00 / MCF or less

Other options require 4.0 TCF or higher and / or the significant higher gas prices

19

Economic Analysis - Sensitivities

1. Development costs (most sensitive)

2. Pricing

3. Reserve Size

Results

21

Economic Analysis - Royalty

Royalty of 5% and 10% had modest sensitivity impact

However, base reserve and price, 5% and 10% royalty result in marginal to sub-marginal economics

Given political sensitivity with foregoing royalty revenue, other revenue methods must be considered

22

Other Revenue Sources

[Randy any ideas??]Confirm higher reserves (exploration)Higher Prices likely

Benchmarking

24

Fiscal System Benchmarking

Benchmarked with the following countries:Netherlands IrelandNorwayTrinidadAlaskaCanada – Nova Scotia

25

Benchmarking Recommendations(1)

Pricing tied to NE US price and linkage to price of competitor fuels

No domestic market obligation or export restrictions (i.e. lack of infrastructure, small dispersed population - no local market)

Consider State involvement for direct marketing of its share

26

Benchmarking Recommendations(2)

Local content quota, with focus on Labrador people, in the issuance for future exploration licenses and SDL’s.

Province must be innovative and flexible in making new gas legislation to promote exploration.

Gas fiscal terms and tax incentives need to balance restricted operating environment with accrued economic value

27

Significant Discovery License (SDL)

Issued by CNOPBSDL have no prescribed date for expireNo economic trigger for operator to

move forward when market conditions allow

No requirements for company to periodically revisit economics if pricing environment changes

28

SDL - Recommendation

Requirements should be designed to place onus on operators to revisit the economics on a bi-annual basis

The trigger could be when the gas price exceeds a specific threshold

29

Justification for NE US Market

Reserve SizeProximity to NE USUS gas pricing (vs Europe pricing)Low local domestic consumption

31

Local Benefits

The people of Labrador should be the ones who benefit most

Best opportunities in marine transportation Particular emphasis should be on training in

marine sector Other opportunities at the offshore

facility and onshore support

Association Members of Labrador Métis Nation. Other residences of Labrador who are members of

collective bargaining agencies Other residences of the Province of Newfoundland

Diversity

In addition to First Nations people, commitment to provide fair and equal opportunities should be given to: WomenPeople with disabilities Other visible minorities

QHSE – System Integration

“Us and Them” Gap Demonstrative actions (physical behaviour) Communications (face to face meetings, focus

groups, personal written notices, a vehicle for “bottom up” communications as well as “top down)

Consistent reactions to all incidents Regular follow-up and closeout Safety training and drills

46

Environment Impact - Exploration

Reported effects in mammals Reported effects in fishSeismic guns deployment (determine

environmental effects, horizontal Vs downward)

Other means of exploration and data acquisition are less harmful to environment (electrical surveys, gravity, magnetic, satellite, etc.)

47

Environment Impact - Drilling

Drilling fluids Impacts water column and seafloor

differentlyReduce light penetrationDecrease in sea lifebiological changes in fish larvaeTechnology and advances in drilling fluids

can reduce impact

48

Environment Impact - Drilling

Drilling Cuttings Impact is proportional to solids dischargeThe fate of the drilling cuttings piles

depends on thickness, ocean condition, conditions of discharge and fluids retention on cuttings

Estimate1-2 years for initiation of recovery after discharge has stopped

Limits for discharge imposed by law

49

Environment Impact - Production

Most significant contaminant is the produced water Produced water is composed of dispersed oil and

dissolved organic compounds, metals, including aromatic compounds, organic acids, phenols, inorganic compounds, and also of chemicals added in the production/separation line.

Its chemical composition varies over a wide range and depends on attributes of the reservoir’s geology.

The produced water and any other discharge are closely monitored to minimize adverse effects

50

Environment Impact – De-comissioning

Disposal in deep waters can impact sea life

May be considered for an artificial reef Removal and dismantling of the

installation is an option

51

Environment Impact – Spills

Operator company must submit contingency plans for environmental emergencies to CNOPB

CNOPB liaisons with environmental advisory agencies

CNOPB helps to design and implement the process through which the public may participate in the review

52

Conclusion (1)

4.3 TCF of gas, potential of 19 TCF FPSO – CNG option most favorableBase reserve and price, 5% and 10%

royalty result in marginal to sub-marginal economics

Given political sensitivity with foregoing royalty revenue, other revenue methods must be considered

53

Conclusion (2)

Exploration to confirm reserves required Gas Clause RequiredMarket – NE USLocal Benefits Agreements required,

other local initiatives that could be taken
