Mustang Draw Production runs 30 compressors in the condensate window of the Eagle Ford, in Karnes County. Each moves about 1,200 Mcf a day. In September the fleet ran 94%, and the operations meeting priced the deferred gas at $2.60 an Mcf and moved on.
That number left out the most valuable thing in the pipe.
Gas is only half the bill
When a compressor in a liquids-rich area goes down, the condensate that would have dropped out of that gas stops too. At a yield of 60 barrels per million cubic feet, it adds up fast:

The condensate was worth more than the gas. Pricing the downtime as gas alone would have captured $168,480 of a $432,864 month.

Use your own yield
Condensate yield varies across the play, from near zero in the dry gas window to well over 100 bbl/MMcf in the richest areas. It also shifts as wells decline. Use the yield from your own sales statements, not a basin average.
The rule of thumb that stuck
At these numbers, one unit down for one day costs about $8,016. Mustang Draw put that figure on the whiteboard in the field office. It changed how fast the after-hours callouts got made.
