Composite operating income per BOE measures upstream operating income relative to total oil-equivalent production.

It combines realized revenue and the issuer's included operating-expense base into one per-unit profitability measure.

EOG example

EOG reported 2025 composite average operating income of $14.20 per BOE, down from $20.79 in 2024.

Its same table showed composite operating revenue and other of $50.32 per BOE and composite operating expenses of $36.12 per BOE.

Why it matters

A producer can grow BOE volumes while per-unit profitability deteriorates if realized prices fall or unit costs rise.

Operating income per BOE therefore helps investors separate volume growth from unit economics.

Read the exclusions

EOG's per-unit operating-cost table excludes exploration costs, dry-hole costs, impairments, marketing costs, and taxes other than income from the listed total cost components.

That means the per-BOE operating-income presentation should not be treated as a full-cycle corporate breakeven.

Compare it with capital spending, reserve replacement, exploration expense, and financing costs before drawing a conclusion about economic returns.

Where this concept fits

Operating cost and per-unit profitabilityCurrent relationship
Lifting cost frames field-level production expense, GP&T cost captures processing and delivery, and DD&A per BOE allocates capitalized asset costs across production. Composite operating income per BOE then shows the resulting issuer-defined per-unit operating profitability after the included cost base.

Commodity realizations and revenue per BOE
Crude and natural-gas benchmark differentials plus NGL realization relative to WTI show how market and location effects shape pricing, while composite operating revenue per BOE combines those realizations with production mix into one issuer-level revenue measure.

Reserve renewal, development capital, and standardized value
Reserve replacement and finding-and-development cost connect depletion with reserve renewal. Developed and undeveloped reserves show development status, PUD conversion volume and capital cost show execution, and future production and development costs feed the standardized discounted reserve-value calculation.
