Petroleum Service Co

Petroleum Service Co, a small business based in Wilkes-Barre, Pennsylvania, supplies petroleum-based products, lubricants, corrosion preventives, and related industrial compounds to federal agencies as a prime contractor (99% of recent awards) under total small business set-asides and full-and-open competition. The company operates primarily through two federal vehicle types: a GSA Multiple Award Schedule (MAS) contract with a $500 thousand ceiling through April 2027, and Defense Logistics Agency Blanket Purchase Agreements for direct supply of preservatives, cutting oils, lubricants, and fuel oils to military and civilian customers.

Petroleum Service Co's customer base is heavily concentrated in DLA supply chain work. Defense Logistics Agency Troop Support Construction and Equipment accounts for 93 awards and $1.5 million in combined potential value — by far the dominant customer. The Department of Homeland Security U.S. Coast Guard represents the second-tier customer with 20 awards ($369 thousand), followed by the Department of the Navy Naval Sea Systems Command (9 awards, $135 thousand) and the Department of the Army Communications Electronics Command (51 awards, $58 thousand). These top five customers account for 71% of award count and 82% of combined potential value. GSA Federal Acquisition Service, while representing only one award, carries a $500 thousand MAS contract ceiling that acts as an indefinite vehicle for task orders issued by Navy Installations Command and Coast Guard sectors.

The company's capability portfolio centers on preservative and sealing compounds (107 awards across the NAICS and PSC classification), cutting and lubricating oils (59 awards), and fuel oils (53 awards), with ancillary work in heat-transfer fluids, corrosion preventives for vessel platforms, and aviation smoke oils. Representative work includes a $69 thousand delivery order from Coast Guard Sector Key West for motor oil under the MAS contract (September 2022, completed October 2022); a $37.1 thousand delivery order to U.S. Pacific Fleet Forces for Mobil Delvac 1640 lubricant under the same MAS vehicle (August 2023); a $29.4 thousand total small business set-aside purchase order from Coast Guard for corrosion preventive compound (October 2024); and a $22.2 thousand Navy Installations Command delivery order for aviation paraffin-based smoke oil under MAS for Patuxent River operations (April 2026). Petroleum Service Co holds positions on eleven DLA Blanket Purchase Agreements, the most significant carrying 11 task orders, demonstrating sustained supply-chain integration with defense logistics infrastructure.

Activity has remained flat to slightly declining — five awards in 2022 and 2023, four in 2024 and 2025, one through April 2026 — across a 255-award historical footprint stretching back to 1994. The company carries minimal subcontract exposure; two sub awards appear in the recent portfolio, both 2025-dated: consumable oils supplied to General Dynamics OTS in Wilkes-Barre for M795 ammunition production, and Tectyl 891D supplied to Vigor Marine for USS John S McCain maintenance. Combined potential value across all awards totals $3.1 million, with $2.5 million obligated (81% realization rate), indicating a mature, transactional vendor footprint heavily weighted toward small-dollar, recurring supply orders rather than contract growth.
