First, a little math refresher about ratios or fractions:

To figure out how fast you’ve been driving in your Chevy Volt, measure how many miles you’ve driven and divide those miles by the number of hours you’ve been driving. For example, if you drove 70 miles in 2 hours, that’s 70 miles divided by 2 hours, or 35 miles per hour. That is the average, of course, because at any point you could have been going 120 mph or 5 mph.

We bring you this math lesson because today’s essay quantifies dollars generated from the sale of frac services in 2017 for the hydraulic horsepower each frac company owned. Think of it as dollars per horsepower (for 2017).

Some companies are fairly straightforward because they are public, which means they might report both their total frac revenues and the frac horsepower (HHP) in their fleet at year’s end. Keane, for example, is expected to report $1.6B in total revenues for 2017, and they had about 1.2M HHP at year’s end for $1370/HHP.

ProPetro is also straightforward: $0.9B frac revenues and 0.7M frac HHP, or $1230/HHP.

Some of the big companies, however, are frustratingly opaque. Halliburton, for example. We think they might have $5.5B US frac revenues in 2017 and 3.3M HHP in the fleet, or $1650/HHP, but we really don’t know. This is an estimate based on research and research and research.

Small companies can be opaque as well. What is the incentive of a privately held frac company to tell a market research firm what their sales are and what their fleet looks like?

Dealing with both transparent and opaque, we’ve created a chart plotting several of the frac service companies’ estimated dollars per HHP for 2017:
