Activity came back in 2026. Cash did not. The US rig count is up roughly 8 percent year over year, yet the majors are reporting softer revenue and days sales outstanding near decade highs. The working capital story this year is billing leakage.
Start with the activity side, because it is real. Baker Hughes counted 587 US rotary rigs on July 24, up 45 from a year earlier, with 450 of those targeting oil. The count strung together five straight weekly gains this summer, its best run since early 2025. Our sister desk at rigs.work has a good breakdown of what the weekly count does and does not tell you, and the short version is this: more rigs, but not the pricing power they used to carry.
The price side explains why. EIA's July Short-Term Energy Outlook put Brent at $82 for 2026 and $65 for 2027, with US crude production still climbing to 13.8 million barrels a day this year. More supply, a softer forward curve, and a service sector working harder for the same dollar.
Baker Hughes; up 45 from 542 a year earlier, with 450 rigs targeting oil.
Now the part nobody puts on the slide. SLB ended March with roughly 93 days of sales in receivables, against a ten-year median near 86, and its first-quarter revenue was down 11 percent year over year. Halliburton's North America revenue fell 4 percent in Q1, and its days sales outstanding has averaged about 78 days across the past five years. These are the best-run companies in the industry, carrying two to three months of revenue in other people's pockets. The independents and mid-size pressure pumping, cementing and rental shops run longer, not shorter.
That gap is what we call billing leakage, and it is not exotic. It is lost or late field tickets, invoices that miss the client's cut-off, rate disputes that should have been settled at the wellsite, and standby or demurrage charges that never get billed at all. Manual invoice processing runs $12.88 to $19.83 a ticket, per Ardent Partners, with error rates of 3 to 5 percent on keyed data. Deloitte pegs the average cost of a supplier payment at about $8, with 62 percent of it manual labor. None of that is market risk. All of it is process.
The arithmetic of a slow receivables cycle
Take a $50 million service company sitting at 78 days DSO, in line with the majors. It is carrying about $10.7 million in receivables. Shave 14 days off the cycle and you free roughly $1.9 million of working capital without adding a single job. That is not a forecast; it is division. Your own AR clerk can run it for your books in five minutes, and the answer will be uncomfortable either way.
Near the top of its own ten-year band; the majors finance two to three months of revenue in receivables.
What makes 2026 different from the last down cycle is that the escape hatch is closed. During the 2020 downturn, service companies cut costs and waited for the rebound. The rebound came, and it brought this: EIA sees Brent at $65 in 2027. Nobody in the C-suite is forecasting a pricing cure. Working capital is now the only balance sheet line a service company can move on its own, and the fastest lever inside it is the distance from job complete to invoice ready.
Where the leakage sits, by the numbers
- Field capture: every ticket that leaves the wellsite unsigned or unphotographed is a dispute waiting to happen. Vendors selling digital capture report payment cycles cut in half, from 60-plus days to 30 or less, with near-zero ticket error rates. Take vendor claims with salt; the direction of travel is still the story.
- Rate validation: rate cards that live in email threads guarantee two-day rate disputes. A live rate reference kills most of them before the invoice goes out.
- Billing runs: month-end batching turns a ten-day invoice cycle into a twenty-day one. Daily or weekly runs are the cheapest fix available.
The market desk view is blunt: 2026 revenue will not rescue a sloppy receivables cycle, and 2027 pricing will not either. Companies that treat billing as an operations discipline, not an accounting ritual, will carry the cash that everyone else is financing. If you want to see where your own books leak, the team at OpsFlo runs billing-flow audits for oilfield service companies, and the operations platform itself is built around field capture and fast invoice runs. Our Q2 2026 benchmark file has the latest cycle-time numbers across the sector, and we have written before on how to reduce days to invoice.
Here is the honest close. The industry spent 2025 waiting for activity and got it. It spent the first half of 2026 waiting for pricing and will not get it back. The companies that book a working session on their billing cycle this quarter are the ones carrying next year's cash. The rest will keep financing it for their customers, at their own cost.
