Frontiers · Oil & Energy · Producing interest
Revenue is only the beginning.
A simplified royalty-and-production-tax structure. Working interest bears its proportional field costs; the purchase price is for the interest acquired, not the entire field.
Producing working-interest appraisal
Follow realised revenue through royalty burden, taxes, field costs, debt and closure to equity returns.

Closure creates a non-conventional cash-flow pattern. The numerical search found 2 IRRs (-27.0%, 7.9%); use NPV and the cash-flow schedule rather than selecting one rate.
Investor annual cash flow

NPV break-even initial benchmark: $76.76/bbl, holding the selected growth path and other inputs constant. This is a full-investment break-even, not a lifting-cost measure.
Annual producing-interest waterfall
Net revenue is after the royalty burden. Production tax is applied to WI gross revenue, before royalty. Final cash includes closure and full debt principal. There is no residual sale value or automatic shutdown.
