How the numbers are calculated

Every figure uses the same math Vendor Callout prints on a monthly vendor report, so a number from this page holds up when someone checks it line by line.

Down unit-hours

units × hours in the month × (1 − runtime %)

Hours in the month are 672, 696, 720 or 744, not a 730-hour average.

Deferred production value

down hours × (BOE/d per unit ÷ 24) × price per BOE

Gross value before LOE, taxes and royalties: revenue the month didn’t book. Usually the largest number on the page by far.

Rental paid on idle units

down hours × (monthly rental ÷ hours in the month)

The rent you paid on iron that wasn’t compressing.

Credit owed under the runtime guarantee

allowed hours = (100% − guarantee) × hours in the month × units
credit = max(0, down hours − allowed hours) × hourly rental

Contracts credit each unit separately, month by month. This page uses a fleet average, so if a few chronic units carry most of your downtime, the real credit is higher than shown.

Frequently asked questions

Yes, and it is the headline. Every result shows the barrels of oil equivalent that stayed in the ground instead of crossing the sales meter this month, and what they were worth, next to the rental and the credit. In Vendor Callout, every callout carries its own deferred-production figure from that unit’s production rate, so you watch it accrue on the dashboard and see it on the monthly report.

A compressor that is down leaves the oil and gas in the reservoir; they are produced later, so the revenue comes late rather than never. Late revenue is worth less, and some volumes can be lost for good (gas flared or vented in an upset, or production a declining well never makes up), but most of it is deferred. Many operators still call it lost production; the arithmetic is the same.

The credit is capped by the rental: at most, it returns the rent for the hours beyond what the contract allows. Deferred production is the oil and gas the unit should have moved to the sales meter. In the default example, one unit down for an hour defers about $547 of production against about $6 of rental. The credit pays for the documentation; the runtime pays for everything else.

Use your best estimate, then check it. Without a timestamp on every callout, vendor arrival and return to service, runtime is a guess, and so are the deferred production and the credit.

Yes. Convert at 6 Mcf per BOE, or enter Mcf/d per unit with a price per Mcf. The math is the same. Vendor Callout itself tracks wet-gas fleets in Mcf/d and condensate yield.

Use the fleet average: total production that moves through compression divided by the number of units. For a sharper number, run the calculator once per route or field and add the results.

It is what one percentage point of fleet runtime is worth per month in production and rental combined. It is the clearest way to size a goal: moving from 92% to 95% is worth three of those points every month.

Rarely. Credits are paid on documented downtime that is presented to the vendor. If it isn’t documented, it’s a free outage.
