Mineral Rights & Royalty Calculations Flashcards

Under a 640-acre pooled unit, a tract of 80 acres is included. If the unit well produces $100,000 net revenue per month, what is the tract's proportionate share before royalty?

Answer: $12,500

80/640 = 1/8 tract participation; $100,000 × 1/8 = $12,500.

A lease grants a 1/8 royalty. The lessor later conveys a 1/32 NPRI to a third party. What royalty does the lessor now effectively retain?

Answer: 3/32

Lessor's royalty remains 1/8 (4/32), but 1/32 is burdened to the NPRI, so lessor nets 4/32 − 1/32 = 3/32.

Which of the following best describes the 'market value' royalty calculation method?

Answer: Royalty is based on the prevailing market price at the wellhead regardless of contract price

Under the market value method, royalty is calculated using the market price at the point of valuation, not necessarily the price the lessee actually received.

A 'Pugh clause' in an oil and gas lease primarily serves to:

Answer: Release acreage outside a pooled unit from the lease at end of primary term

A Pugh clause (or 'freestone rider') releases non-pooled acreage — and in a vertical Pugh clause, non-producing depths — from the lease when pooling holds only part of the tract.

Royalty interest is classified as which type of property interest?

Answer: Real property

Royalty interests are real property interests running with the land, not personal property.

An operator sells gas at the wellhead for $2.50/Mcf. The same gas has a market value of $3.00/Mcf at the wellhead. Under a 'market value' royalty clause with a 1/4 royalty, the royalty owner receives:

Answer: $0.75/Mcf

Market value clause uses $3.00/Mcf; $3.00 × 1/4 = $0.75/Mcf.

A 'shut-in royalty' clause allows an operator to keep a lease alive when:

Answer: The well is capable of production but is shut in due to lack of market

Shut-in royalty clauses allow the lessee to maintain the lease by paying a fixed shut-in payment when a gas well is capable of production but lacks a market or pipeline connection.
