What Is Primary and Secondary Containment? CrossEnergy's Oilfield Site Services Explained
- 14 hours ago

Oilfield operations across Colorado and Wyoming run on a foundation of safety practices that most outsiders never see. Among the most critical of these practices are primary and secondary containment systems. Done well, they protect workers, the environment, and the long-term viability of the operation. Done poorly, they create the kind of incidents that make regulatory news and shut down production. CrossEnergy has built a dedicated containment division to deliver this work at the standard the industry actually requires.
This article explains what primary and secondary containment actually mean, why they matter so much in oilfield operations, and how the CrossEnergy team delivers containment services across Greeley, Northern Colorado, Weld County, and Wyoming locations including Casper, Cheyenne, Laramie, and Wheatland.
What Primary Containment Means
Primary containment refers to the vessels, tanks, piping, and equipment that hold the fluids being produced, processed, or stored in an oilfield operation. The primary containment system is the first line of defense between the produced fluids and the surrounding environment. Crude oil tanks. Produced water tanks. Process piping. Wellhead equipment. Separators. All of these are part of the primary containment system.
Effective primary containment requires equipment that is properly specified for the service conditions, properly installed, properly inspected, and properly maintained. Material selection matters because some produced fluids are corrosive. Pressure ratings matter because some systems operate well above atmospheric pressure. Connection integrity matters because most leaks begin at fittings and flanges rather than through tank walls.
What Secondary Containment Means
Secondary containment is the system that catches and contains any release from the primary system. Berms around tank batteries. Liners under containment areas. Drainage and collection systems that capture spilled fluids before they reach soil or groundwater. The secondary containment system is the safety net that ensures a primary containment failure does not become an environmental incident.
Federal and state regulations specify minimum requirements for secondary containment capacity, typically requiring that it can hold the full volume of the largest tank plus a safety margin for precipitation. The materials, construction, and inspection of secondary containment systems are subject to regulatory oversight, and operators who cut corners face significant exposure when something goes wrong.
Why This Matters So Much in Modern Oilfield Operations
Oilfield operations face higher scrutiny today than they have at any point in the industry's history. Regulatory expectations have tightened. Community expectations have risen. Insurance carriers require documented compliance. Lenders and investors evaluate environmental risk as part of capital allocation decisions. In this environment, containment is not just an operational detail. It is a foundational element of running a serious, professional oilfield operation.
Operators who invest in strong primary and secondary containment systems protect themselves on every front. They reduce the risk of regulatory action. They reduce insurance exposure. They build credibility with regulators, communities, and investors. They run safer operations for their crews. They preserve the long-term viability of their leases and assets. The investment pays back in dozens of small ways every year, and in one or two big ways when an incident is prevented that would otherwise have caused major damage.
The CrossEnergy Containment Division
CrossEnergy has built a dedicated containment division that focuses specifically on primary and secondary containment work for oilfield operators across Colorado and Wyoming. The division is led by Derek Coron, who brings deep operational experience and a disciplined approach to containment system design, installation, and maintenance. The team handles the full scope of containment work, from initial site assessment through installation and ongoing service.
What the Containment Division Delivers
Tank battery secondary containment design, installation, and rehabilitation.
Containment liner installation, including welded HDPE liner systems for demanding service conditions.
Berm construction and grading for compliant containment capacity.
Containment inspection, repair, and ongoing maintenance contracts.
Coordination with regulatory inspections and documentation support.
Integration of containment work with broader site services across the same operator's facilities.
Hydrovac Excavation and Site Preparation
Beyond containment specifically, CrossEnergy provides hydrovac excavation services that support a wide range of oilfield site work. Hydrovac uses pressurized water and vacuum to excavate around buried utilities, lines, and equipment without the risk of mechanical damage that comes with traditional excavation. For oilfield sites with multiple buried systems running between facilities, hydrovac is often the only safe way to do site preparation work.
The CrossEnergy hydrovac team handles excavation for new equipment installations, repair work on existing systems, utility location, and site preparation for new construction. The equipment is modern, well-maintained, and operated by experienced crews who understand the specific demands of oilfield work.
Flowback and Wellhead Services
CrossEnergy also provides flowback and wellhead support services that operators across Colorado and Wyoming rely on during critical phases of well operations. The team understands the demanding conditions and safety requirements that come with flowback work, and brings the discipline and equipment needed to deliver consistent results.
Mobile Burner Operators and CDL Drivers
Specialized field roles like mobile burner operators and CDL drivers round out the CrossEnergy service offering. These specialized capabilities allow CrossEnergy to support operators across a broader range of needs than a single-service contractor could deliver. From a Greeley headquarters and Wyoming operational presence, the team mobilizes to sites across the region with the equipment and trained personnel each project requires.
The Experience and Safety Foundation
CrossEnergy brings two hundred plus years of combined team experience to every project, with a track record of three hundred to four hundred plus successfully completed projects across the region. The company maintains active safety partnerships and proper licensing for the work it performs, which gives operators confidence that every job will be delivered to industry standards.
For oilfield operators, this combination of experience, safety culture, and integrated service capability is genuinely rare. Most contractors specialize narrowly. CrossEnergy has built the depth to handle multiple aspects of oilfield site services from a single operational base, which simplifies project logistics and improves accountability for the operator.
Smart Tools Supporting the Field
Modern oilfield site services require modern operational tools. CrossEnergy uses AI-assisted scheduling, digital site documentation, and integrated project management software that helps the team coordinate work across multiple concurrent projects without losing field-level accountability. The technology supports the team. The work itself remains in the hands of trained operators, drivers, and field crews who deliver the service operators actually need.
