Production volume in barrels of oil equivalent per day, often written BOE/day, BOED, MBOED, or MMBOED, measures average daily oil and gas production on a common energy-equivalent basis.
A common conversion treats 6,000 cubic feet of natural gas as one barrel of oil equivalent.
Why BOE per day matters
Daily production is one of the clearest measures of operating scale for an upstream producer.
ConocoPhillips reported first-quarter 2026 total company production of 2.309 million BOE per day, while Occidental reported fourth-quarter 2025 global production of 1.481 million BOE per day.
Investors use production volume to assess:
- organic growth;
- acquisition effects;
- field declines;
- capital efficiency;
- guidance execution; and
- revenue sensitivity to commodity prices.
BOE is an energy conversion, not a price conversion
The BOE convention combines oil and gas using relative energy content.
It does not mean one BOE of natural gas has the same market value as one barrel of crude oil.
Occidental's reserve disclosure explicitly notes that BOE equivalence does not necessarily produce price equivalence.
That is why Oil Production Mix matters.
Average daily production can hide mix changes
Two companies can each produce 500,000 BOE/day while having very different economics if one is oil-heavy and the other is gas-heavy.
Production can also shift between:
- crude oil;
- condensate;
- natural gas liquids;
- natural gas; and
- geographic regions.
Gross and net production are different
Investors should confirm whether a company reports production before or after royalty interests, production-sharing adjustments, or other ownership effects.
Acquisitions and divestitures can also make year-over-year growth look very different from same-asset production growth.
Primary-source examples
BOE/day is most useful as the volume leg of upstream economics, alongside commodity mix, realized prices, costs, reserves, and capital spending.
