Indian Example: Initial Reporting for Processed Gas in Non-Index Zone (Major Portion) Areas

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!

Product Code 03 – Residue Gas

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

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 fee. You may wish to determine the reasonable portion of plant fuel and exclude it from royalty calculations.

Step 1:

In order to determine the 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 residue Btu factor is 1.13228 MMBtu/Mcf

Gas should be reported at 14.73 psi. See the Oil and Gas Indian Payor Handbook Section 2.4.3 for more information.

To calculate a residue Btu factor, divide the net residue gas MMBtu (1,922.39 MMBtu) by the volume of the net residue gas Mcf (1,697.81 Mcf). The residue Btu factor is 1.13228 MMBtu/Mcf.

Step 2:

Calculate the plant fuel volume (Mcf):

  • Identify the total 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 plant fuel volume is 288.27 Mcf
To calculate the plant fuel volume (Mcf), divide the contractual allocated fuel (326.40 MMBtu) by the Btu factor (1.13228 MMBtu/Mcf). The total plant fuel volume is 288.27 Mcf.

Step 3:

Calculate the total residue gas sales volume:

  • Add the volume of the residue gas sales (1,697.81 Mcf) (G) to the plant fuel volume from Step 2 (288.27 Mcf)
  • The total residue gas sales volume is 1,986.08 Mcf
To calculate the total residue gas sales volume, add the volume of the residue gas sales (1,697.81 Mcf) to the plant fuel volume from Step 2 (288.27 Mcf). The total residue gas sales volume is 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 plant fuel, here the “Contractual Allocated Fuel” (326.40 MMBtu) (F)
  • The total residue gas sales energy content is 2,248.79 MMBtu

Gas is measured by volume (cubic feet) and by its energy content (MMBtu). The energy content (MMBtu) is not a measurement of volume.

To calculate the total residue gas sales MMBtu, add the energy content of the residue gas sales (1,922.39 MMBtu) to the energy content of the plant fuel (326.40 MMBtu). The total residue gas sales energy content is 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 unit price ($3.13905/MMBtu) (J)
  • The residue gas price may not be reduced by any costs of placing the gas into marketable condition under §1206.174(h)
  • The total residue gas sales value is $7,059.06
To calculate the residue gas sales value, multiply the residue gas sales MMBtu (2,248.79 MMBtu) by the residue unit price ($3.13905/MMBtu). The total residue gas sales value is $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
To calculate the Royalty Value Prior to Allowances (RVPA), multiply the residue gas sales value ($7,059.06) by the royalty rate (18%). The total RVPA is $1,270.63.
