NAICS 213112 – Support Activities for Oil and Gas Operations encompasses specialized services that enable the exploration, drilling, production, and maintenance of oil and gas infrastructure, including well site preparation, pipeline inspection, leak detection, fluid handling, and environmental compliance support. These services are critical to ensuring operational efficiency, safety, and regulatory adherence across upstream energy activities. While primarily associated with commercial energy markets, this NAICS code has emerged as a niche but vital component of federal contracting, particularly where DoD installations and remote military facilities rely on on-site fuel storage, transportation, or emergency response capabilities. Contractors in this space often provide technical expertise in hazardous material handling, pressure testing, and remote monitoring systems, aligning with federal standards for environmental stewardship and infrastructure resilience. Top contractors in this sector include LEAK DETECTION SERVICE INC, a specialized small business known for its precision leak detection and pipeline integrity services. The competitive landscape is dominated by niche vendors with niche technical certifications rather than large primes, reflecting the highly specialized nature of the work and the need for field-deployable, rapid-response capabilities. The Department of Defense is the primary federal buyer, procuring these services to support fuel logistics at remote bases, military ranges, and expeditionary operations where fuel infrastructure requires continuous monitoring and maintenance. Demand is driven by mission-critical energy security initiatives and compliance with environmental regulations on federal lands. The market is characterized by low contractor density and high technical barriers to entry, creating concentrated opportunities for firms with proven expertise in hazardous environment operations, ANSI/API standards, and DoD-specific environmental protocols. Contractors with ISO certifications and experience in military logistics environments are best positioned to compete in this specialized segment.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 213112 work as a small business.

$47.0M
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
