How the numbers are calculated

Straight arithmetic from what your units move, so anyone in the room can check it.

Deferred volume

units × production per unit per day × days × (1 − runtime)

Oil in barrels, gas in Mcf or rolled-up BOE.

Condensate carried by gas

condensate (bbl) = deferred gas (Mcf) ÷ 1,000 × yield (bbl/MMcf)

Zero for dry gas.

Value

oil × oil price, or gas × gas price + condensate × condensate price

Gross value before LOE, taxes and royalties.

BOE and annualizing

BOE = oil + condensate + gas ÷ 6 · per year = per day × 365

The 6:1 energy-equivalent standard.

Frequently asked questions

Multiply what a unit moves per day by the days it was down. For a fleet: units × production per unit per day × days in the month × (1 − runtime). This page does that for oil, for gas with condensate, or for BOE.

Whatever your field reports in. Gas-lift and oil-weighted fleets usually think in barrels of oil per day. Gas gathering and wellhead compression think in Mcf per day with a condensate yield. BOE is useful when you report everything rolled together.

Barrels of condensate recovered per million cubic feet of gas sold. Sales accounting has it: condensate sold divided by gas sold, in MMcf. When gas does not move, the condensate it would have carried does not move either.

Because a compressor that is down does not destroy the oil and gas; it leaves them in the reservoir, and they are produced later. What downtime takes is time: the revenue arrives months or years late, and a barrel sold later is worth less than one sold today. Some of it can be lost for good: gas flared or vented during an upset, production a declining well never makes up, or volumes still in the ground when a lease or the field’s life ends. Many operators still call all of it lost production; the arithmetic is the same.

This page uses 6 Mcf per barrel of oil equivalent, the industry energy-based standard. Use the Gas to BOE Converter to try other ratios.
