Last updated September 2026
The short answer
In oilfield services, days sales of inventory typically runs 100–200+ days — above the cross-industry band of 61–90 days. Project cycles swing DSI; under 100 is excellent.
Formula
DSI = (Average Inventory ÷ Cost of Goods Sold) × 365 Oilfield services against the cross-industry band
| Industry | Typical DSI | What good looks like |
|---|---|---|
| All industrial distribution | 61–90 days | Under 60 days is strong for wholesale distribution |
| Oilfield Services | 100–200+ days | Project cycles swing DSI; under 100 is excellent |
Lower is better on this metric. Every other industry benchmarked for DSI is in the full benchmark table.
