Mineral Rights & Royalty Calculations Flashcards

A mineral deed conveys '50% of the minerals' under a 200-acre tract. The grantee's mineral acre ownership equals:

Answer: 100 mineral acres

50% × 200 acres = 100 mineral acres owned by the grantee.

When calculating the net revenue interest (NRI) for a working interest owner, which formula is correct?

Answer: NRI = WI × (1 − total burdens)

NRI equals the working interest multiplied by the complement of all royalty/ORRI burdens: NRI = WI × (1 − total burdens).

A lessee has a 100% WI and pays a 1/5 royalty plus a 1/40 ORRI. The lessee's NRI is:

Answer: 0.775

Total burdens = 1/5 + 1/40 = 8/40 + 1/40 = 9/40 = 0.225; NRI = 1.0 × (1 − 0.225) = 0.775.

The 'rule of capture' in oil and gas law means that:

Answer: A landowner owns oil and gas produced from their well regardless of where it migrated from

Under the rule of capture, a producer owns oil and gas brought to the surface even if it migrated from beneath a neighbor's land.

An operator pools a 40-acre tract into a 160-acre unit. The tract royalty is 1/4. The royalty owner's effective royalty based on pooled production is:

Answer: Both A and C are equivalent

A: 1/4 × (40/160) and C: (40/160) × 1/4 are mathematically identical, both representing the tract's proportionate royalty share of unit production.

A landman discovers a lease contains a 'gross proceeds' royalty clause. This generally means:

Answer: Royalties are calculated on the total amount received without deductions

A gross proceeds clause bases royalty on the total sales price received by the lessee, with no deductions for post-production costs.

Under the 'at the well' royalty valuation point, post-production costs such as transportation and compression are generally:

Answer: Deductible from the royalty owner's share

When valuation is 'at the well,' costs to move gas from the wellhead to market are typically deductible from royalty calculations unless the lease says otherwise.
