Indian Example: Processed Gas Reporting (Arm’s Length Dedicated Contract) in an Index Zone with Alternative Dual Accounting

Detailed Example

The following is based on a sample statement. Statements may vary. Be sure to read carefully and contact royaltyvaluation@onrr.gov if you need further assistance!

The assumptions below are for purposes of this example only. The assumptions provide the basis to show you how to perform the necessary calculations. Your situation may vary from these assumptions. Please contact royaltyvaluation@onrr.gov with specific questions.

Assumptions for this example:

1.  The gas is produced from an Indian lease in the Central Rocky Mountain Index Zone.

2.  The gas is valued as processed gas under ONRR’s regulations.

3.  The gas is transported, processed, and sold under arm’s-length contracts.

4.  The processor retains 15% of the residue gas and NGLs.

5.  No condensate is recovered along the pipeline or in the gas plant. You should check your statement or transportation invoice for condensate. If you have questions on how to value or report condensate, please contact royaltyvaluation@onrr.gov.

6.  The royalty rate is 18%.

7.  The prices per gallon of NGL components shown on the example gas plant statement ("price at the plant") are the component prices downstream of the gas plant less the processor’s transportation and fractionation (T&F) fees. The processor deducted a post-plant NGL transportation fee of $0.05/gallon and an NGL fractionation fee of $0.07/gallon from the downstream price. Here, we provided the T&F fee; you may need to check your contract or other sources for the amount.

  • The transportation portion of the T&F fee for this example is NOT a “transportation factor” under the regulations at 30 CFR §1206.178(a)(5).

This assumption falls under "Scenario 2" in the Processed Gas Reporting: Minimum Value Provision for NGLs example. Please see that example for additional information on calculating the regulatory minimum NGL value.

8. The lease instrument for this example does not allow deductions for transportation or processing costs. Therefore, no allowances will be calculated or taken.

9. The NGL minimum value provision for production in Utah under §1206.174(g)(2)(i)(B) requires the use of posted prices at Conway, Kansas. For this example, we assume the below prices:

ComponentPurity Ethane (C2) Propane (C3)Isobutane (iC4) Normal Butane (nC4) Natural Gasoline (C5+) 
$/gallon 0.24890   0.852831.43603 1.34133 2.17513

10.  The production month is January 2019 (as shown on the example statement).

11.  The Indian index zone price is the January 2019 price for the Central Rocky Mountain index zone found on ONRR.gov.

12.  The lessee has NO ownership in the processing plant.

13.  The volume-weighted-average Btu content, calculated from the statement, is 1226 Btu/Mcf.

Part A: Calculate the Gross Proceeds, PC 03 – Residue Gas 

Royalty is due on residue gas resulting from processing, including disallowed plant fuel.

Note: This example includes the assumption the payor has not unbundled. However, the regulations at 30 CFR §1206.179(e) allow for a reasonable amount of plant fuel royalty free. You may wish to determine the reasonable portion of plant fuel and exclude it from royalty calculations. 

Step 1:

In order to determine the disallowed plant fuel volume in Mcf, you need to calculate a residue Btu factor:

  • The Btu factor is the heating value per volume of the residue gas, calculated by dividing the net residue gas MMBtu (1,922.39 MMBtu) (H) by the volume of the net residue gas Mcf (1,697.81 Mcf) (G)
  • The Btu factor is 1.13228 MMBtu/Mcf
Mathematical representation of Step 1. To determine the PC 03 Btu Factor, divide the net residue gas MMBtu by the net residue gas Mcf. For example, divide 1,922.39 MMBtu by 1,697.81 Mcf for a PC 03 Btu factor of 1.13228 MMBtu/Mcf

Step 2:

Calculate the disallowed plant fuel volume (Mcf):

  • Identify the total MMBtu plant fuel reported on the plant statement

             -  In this example, the plant fuel is called “Contractual Allocated Fuel” and is 326.40 MMBtu (F).

  • Determine the total plant fuel volume (Mcf)

             -  Divide the contractual allocated fuel (326.40 MMBtu) (F) by the Btu factor (1.13228 MMBtu/Mcf)

  • The total disallowed plant fuel volume is 288.27 Mcf
Mathematical representation of Step 2. To determine the PC 03 Plant Fuel Volume (Step 2), divide the contractual allocated fuel MMBtu by Btu factor. For example, divide 326.40 MMBtu by 1.13228 MMBtu/Mcf for a PC 03 Plant Fuel Volume value of 288.27.

Step 3:

Calculate the total residue gas sales volume: 

  • Add the volume of the residue gas sales (1,697.81 Mcf) (G) to the disallowed plant fuel volume from Step 2 (288.27 Mcf)
  • The total residue gas sales volume is 1,986.08 Mcf
Mathematical representation of Step 3. To determine the PC 03 Residue Gas Sales Volume (Step 3), add residue Mcf to disallowed plant fuel Mcf. For example, add 1,697.81 Mcf to 288.27 Mcf, for a PC 03 Mcf of 1,986.08 Mcf.

Step 4:

Calculate the total residue gas sales MMBtu:

  • Add the energy content of the residue gas sales (1,922.39 MMBtu) (H) to the energy content of the disallowed plant fuel, labeled “Contractual Allocated Fuel” (326.40 MMBtu) (F)
  • The total residue gas sales energy content is 2,248.79 MMBtu
Mathematical representation of Step 4. To determine the PC 04 Gas Sales Value (Step 4), add residue MMBtu to disallowed plant fuel MMBtu. For example, add 1,922.39 MMBtu to 326.40 MMBtu, for a PC 03 MMBtu of 2,248.79 MMBtu..

Step 5:

Calculate the residue gas sales value:

  • Multiply the residue gas sales MMBtu determined under Step 4 (2,248.79 MMBtu) by the residue gas price ($3.13905/MMBtu) (J)
  • The residue gas price may not be reduced by any costs of placing the gas into marketable condition as described in §1206.174(h)
  • The total residue gas sales value is $7,059.06
Mathematical representation of Step 5. To determine the PC03 Residue Gas Sales Value (Step 5), multiply residue sales MMBtu by residue gas price. For example, multiply 2,248.79 MMBtu by $3.13905/MMBtu for a PC 03 sales value of $7,059.06.

Step 6:

Calculate the Royalty Value Prior to Allowances (RVPA):

  • Multiply the residue gas sales value calculated under Step 5 ($7,059.06) by the royalty rate (18%)
  • The total RVPA is $1,270.63
Mathematical representation of Step 6. To determine the PC 03 Royalty Value Prior to Allowances (RVPA) (Step 6), multiply the sales value by royalty rate. For example, multiply $7,059.06 by 0.18, for a PC 03 RVPA of $1,270.63.
