Alberta Modernized Royalty Framework Post C* Calculator

The Post-C* royalty rate may differ for each product produced from a well. This calculator estimates the gross Post-C* royalty rate for a specific product produced from a well once the well's total revenue, from all hydrocarbon products, equals or exceeds the Drilling and Completion Cost Allowance (C*).

This calculator is for estimation only and is not intended to be a substitute for formal royalty calculations by Alberta Energy. See About Royalties for more information on C* and the Post-C* royalty formulas.


To estimate C*, please see the C* Calculator.


To estimate the Post-C* royalty rate you will need to specify:

  1. The product for which you are seeking a royalty rate
  2. The par price for that product [for par prices see oil and gas].

To estimate gross royalty rates for a well when production may be lower than the maturity threshold you will also need to specify the well's total monthly equivalent production. The total monthly equivalent production is the sum of all commodities produced from the well including oil, raw gas and/or field condensate. For information on conversions required for this calculation please see 'What is the maturity threshold' in the FAQ.
