Mineral Valuation & Appraisal Flashcards

Which approach to mineral valuation is required by the SEC for publicly reported oil and gas reserve values (standardized measure)?

Answer: PV10 using current 12-month average first-day-of-month prices

SEC rules require the standardized measure to use a 12-month unweighted average of first-day-of-month prices discounted at 10% (PV10).

A royalty interest owner receives a check based on the 'proceeds' from sale. Which deduction is most commonly disputed in royalty audits?

Answer: Post-production costs such as compression and transportation deducted from gross proceeds

Post-production cost deductions (gathering, compression, transportation, marketing) are the most frequently disputed items in royalty audits because their permissibility depends on lease language.

What does the term 'gross acreage' versus 'net acreage' mean in the context of mineral valuation?

Answer: Gross acreage is total acres; net acreage adjusts for the fractional working interest owned

Net acreage equals gross acreage multiplied by the fractional working interest, representing the economic equivalent of 100% owned acreage.

Which scenario would most likely cause an appraiser to apply a 'thin market discount' to a mineral property value?

Answer: The property is a small undivided mineral interest with few potential purchasers

Small undivided interests or remote properties attract fewer potential buyers, creating a thin market that impairs liquidity and justifies a marketability discount.

In oil and gas appraisal, what is the significance of the 'b-factor' (hyperbolic exponent) in production decline analysis?

Answer: It measures the rate at which the decline rate itself changes over time

The b-factor in hyperbolic decline (0 < b < 1) quantifies how rapidly the instantaneous decline rate decreases over time, affecting long-term reserve estimates.

Which type of mineral transaction typically commands the highest price per barrel of equivalent reserves on a $/BOE basis?

Answer: Proved developed producing (PDP) acquisitions in core operating areas

PDP reserves in established producing areas command the highest $/BOE because they carry the least risk — production is already flowing with known costs and rates.

When a mineral appraiser 'rolls back' comparable sales to the effective date of appraisal, what adjustment is being made?

Answer: Adjusting for commodity price changes between the sale date and appraisal date

Rolling back adjusts comparable sale prices to account for commodity price differences between when the sale occurred and the effective date of the appraisal, improving comparability.
