Dehn Oil Company

Dehn Oil Company, doing business as Wilson Oil Company, supplies dyed #2 diesel fuel and other petroleum products to the U.S. Army Corps of Engineers as a small business set-aside prime contractor, with a footprint of 15 federal purchase orders totaling $1.6 million in combined potential value since 2020. The vendor operates 100% as a prime contractor across total small business set-asides and competes exclusively in that category.

Dehn Oil Company is a for-profit corporate entity headquartered in Ramsey, Minnesota. The vendor's capability portfolio centers on bulk off-road diesel fuel supply — particularly dyed #2 diesel — and gasoline delivery to support dredging operations, dewatering equipment, and marine machinery along the upper Mississippi River system. Representative contracts include a $249,120 firm fixed-price purchase order for 60,000 gallons of dyed #2 diesel delivered to the Dredge Goetz Fleet's Fountain City Service Base in May 2022; a $222,891.55 purchase order for 52,500 gallons of dyed off-road diesel in July 2022; a $206,880 purchase order for dyed diesel to support the Goetz Fleet in August 2023; and a $115,200 purchase order for 45,000 gallons of dyed #2 diesel to the Fountain City Service Base in June 2025. More recent work includes an August 2025 contract for $19,878.20 and an April 2026 purchase order for $46,800 to supply 10,000 gallons of dyed #2 diesel for delivery across multiple sites between La Crescent, Minnesota and Guttenberg, Iowa.

Customer concentration is extreme and narrow. The Department of the Army Corps of Engineers accounts for all 15 awards and the entire $1.6 million combined potential value, with eleven of those awards placed by the Corps broadly and four by the St. Paul District specifically. Place of performance concentrates on the upper Mississippi River system, with recurring service bases at Fountain City and La Crosse, Wisconsin, Hastings, Minnesota, and Lock and Dam 2. The vendor holds no seats on government-wide acquisition contracts, IDIQs, or BPAs; all work flows through discrete small business set-aside purchase orders. Award volume has remained modest and sporadic — one award in 2021, three in 2022, four in 2023, three in 2025, and one in 2026 — with no discernible growth trajectory and no subcontract activity. The vendor operates no parent-vehicle relationships and functions exclusively as a direct supplier to a single federal customer through routine spot procurements, making competitive reentry against this vendor in Corps dredging fuel supply the primary decision-relevance signal.
