Background

Policy Announcement Dec 1999 to align royalty framework with Industry and market developments.

Key Changes: Distinct royalty treatment for recovered Ethane (Field

Ethane) Royalty recognition of NGL components (In-Stream

Components or ISC) in residue gasSub-Committees (Industry/Gov’t) established

between Jan 2000 – July 2001 to define business rules.


6

Key Outcomes

Field Ethane will be assessed at C2 R% and C2 Net Reference Price ($/gj) that will be different from the Gas R% and Gas Net Reference Price.

Royalty rates for Propane and Butanes will change from the flat rate of 30%. Subject to an expected maximum rate of 30% and minimum rate of 15%, the following formula will be used:

R% = 15SP + 40(PP-SP) PP

SP is the select price for the product PP is the Propane par price for the Propane royalty rate and the Butanes

par price for the Butanes royalty rate.


7

Key Outcomes…..Cont’d

No change to royalty trigger points. Gas royalty will be assessed on the basis of In-

Stream Components (ISC). This will be achieved by assessing royalty on product GAS using facility averages (rate and price) that are based on the ISC compositions of the royalty trigger volumes.

Gas royalty for CAP clients will be based on facility average rates but valuation continues to be based on CAP, where monthly CAP estimate is Client CGF x GRP.


8

Key Outcomes…..Cont’d

Each ISC product will have its own distinct royalty rate, reference price and adjusted IATD which will be used in the facility average royalty rate and price calculations.

Department of Energy (DOE) will invoice royalty on product GAS using the SAF/OAF and volumetric details from the Registry.

Implementation coinciding with the Registry – Production Month 2002-10.

11

FARR% & FAP for Gas

Facility level royalty rate and valuation price for Gas.

Used to assess royalty trigger Gas quantities at charge facility.

Uses the ISC compositions (excluding inerts) of royalty trigger quantities at the charge facility to calculate that facility’s weighted average royalty rate and valuation price (see example illustration).

ISC compositions are reported to the Registry by meter station operators, common stream operators and some facility operators (see Registry ISC Reporting Table slide).


12

FARR% & FAP for Gas…..Cont’d

The royalty rates for the individual ISC products will be the same as the royalty rates for the extracted products (e.g. C2-IC R% = C2 R%).

The vintage for the individual ISC products will be the same as the old/new vintage for the extracted products.

The reference prices for the individual ISC products will differ from the reference prices of Gas and the extracted products (exception C2 Ref Price=C2-IC Ref Price).


13

Low Productivity Allowance Adjustment No change to low productivity well allowance

eligibility. Low productivity allowance adjustment continues to

apply to eligible Gas and Ethane production. For eligible Gas and Ethane production, the Crown

royalty rate is calculated as:R% = RC – (RM – 5) x (16.9 – ADP)2

16.92

ADP is the average daily production of gas for the well event for the production month (103m3).

RC is the Old/New FARR if production is Gas and the Ethane Old/New royalty rate if production is Ethane.

RM is the Old/New royalty rate for Methane ISC


14

Registry ISC Reporting

ISC volume and energy information are reported in the Registry, as a further breakdown of the Gas volume and energy.

ISC factors are reported on Registry RGA submissions.

Submissions to the Registry can be online entry or batch file entry, along with other volumetric submissions.

Not all volumetric activities in the Registry require ISC reporting (see Registry ISC Reporting Table slide).


15

Registry ISC Reporting…..Cont’d

ISC volume and energy must be reported to 3 decimal places for desired precision.

Where ISC reporting is required, aggregate ISC volume and energy must equal corresponding Gas volume and energy (within a tolerance of 0.100 103m3 and 1.000 gj) or both ISC and Gas volumetric submissions will be rejected.

ISC heat value (gj/103m3) must be within the specified heat value range for each ISC product (see ISC Heat Range Table slide).

27

Raw Gas Sale and ISC Factor Reporting on RGA

Raw Gas Sales are identified on Registry RGA submissions.

Raw Gas Sales that are subsequently processed or used as lease fuel are assessed royalty at RARR%, rather than FARR%.

All other Raw Gas Sales will be assessed at FARR %. RARR% is based on the ISC factors (excluding

inerts) identified by the seller on the RGA, rather than the ISC composition of the facility.

Old/New RARR% = (ISC Product Factor on RGA x ISC Product Old/New R%) / ISC Product Factor on RGA (see example illustration).


28

Raw Gas Deliveries To Injection

Crown royalty for raw gas delivered to injection (reported in Registry at a Battery or Gathering System as a disposition to an Injection Facility) is assessed at the FARR% of the Injection Facility and the FAP of the Reproducing Facility.

33

ISC Balancing and FARR%/FAP Using ISC Default

Effective December 2004 calendar month, the ISC receipts at meter stations reported by meter station operators or common stream operators (CSO), must equal the meter station disposition activities reported by pipeline operators. Meter station receipts impact the FARR% and FAP calculations.

For ISC imbalances that existed prior to this change, the DOE continues to perform ISC Balancing and uses the ISC default in calculating the FARR%/FAP calculations.


34

ISC Balancing and FARR%/FAP Using ISC Default…..Cont’d If there is a discrepancy in meter station receipts for

an ISC product, the C5+-IC R% and C5+-IC Net Ref Price will be used for that product in the FARR% and FAP calculations. (see example illustration)

The meter station operator or CSO who submitted the meter station receipts will receive a discrepancy notice from DOE. Notice is generated on day 35 following month of production. (see sample report)

Royalty clients will be notified in Default Report and in supporting reports of FARR%/FAP calculations where ISC default values have been used. (see sample report)


35

FARR%, RARR%, FAP Illustration

See Excel attachment


36

FARR% Calculation for GasOld FARR% =

(ISC Product Energy x ISC Product Old R%) / ISC Product Energy

New FARR% = (ISC Product Energy x ISC Product New R%) /

ISC Product Energy

ISC product energy refers to ISC dispositions at the charge facility that are royalty triggers. If charge facility is an injection facility, ISC product energy refers to ISC receipts rather than dispositions.

Energy from inerts are not included in FARR% calculation.


37

RARR% Calculation for raw gas sales

Old RARR% = (ISC Product Factor on RGA x ISC Product Old R%) / ISC Product Factor on RGA

New RARR% =

(ISC Product Factor on RGA x ISC Product New R%) / ISC Product Factor on RGA

ISC factors of inerts are not included in RARR% calculation.


38

FAP Calculation for Gas

FAP = Facility Reference Price – Facility Gas

Transportation Adjustment Facility Reference Price =

Σ (ISC Product Energy x ISC Product Ref Price) / Σ ISC Product Energy

Facility Gas Transportation Adjustment = [Royalty Trigger Factor – 1] x Facility Adjusted IATD

Royalty Trigger Factor = Σ (ISC Product Energy x Meter Station Factor) /

Σ ISC Product Energy


39

FAP Calculation for Gas…..Cont’d Facility Adjusted IATD =

Σ (ISC Product Energy x Adjusted IATD of ISC) / Σ ISC Product Energy

ISC product energy refers to ISC dispositions at the charge facility that are royalty triggers. If charge facility is an injection facility, ISC product energy refers to ISC receipts rather than dispositions.

ISC product energy in FARR% and FAP calculation is the same.

If the delivery/receipt location of the ISC product energy is not an included pipeline meter station, the meter station factor for the product energy will be 1.00.
