Vapour Tight Tanks

Vapour-Tight Tanks

Vapour tight tanks are intended primarily for the storage of volatile liquids. Vaportight tanks hold and use pressure to force gas vapors to a flare stack. Vaportight tanks also known as (Tornado type tanks, Positive Pressure Systems, and OSY Tanks) are frequently packaged with an integral separator package, flare stack, and all other equipment downstream of the wellhead to form a complete single well battery. Because of this Vaportight tank packages are a mostly used in the temporary production of oil wells.

Benoit rents and sells new and used storage tanks:

Fresh Water Tank Rentals

Fresh water storage is a broad term referring to storage of both potable water for consumption, and non potable water for use in Industrial and agriculture applications.

Frac Water Tank Rentals

Frac Water tanks is referred to as  “Frac Water” because its used to supply fracturing fluids at oil and gas wells.

Emulsion Tank Rentals

Emulsion fluids are primarily produced from wells and require tank storage.

Potable Water Tank Rentals

Potable water or fresh water is for consumption and use in both Industrial and agriculture applications. 

Waste Water Tank Rentals

Waste water is typically a byproduct of work in oil and gas worksites, which require storage and removal.

Tank Customizations

Looking for something customized? No Problem! all of our standard tanks are available with a number of options to suit your specific needs. Options include external insulation, burner systems, catadyne heaters, envirovaults, internal coating, sour service gauge boards and thief hatches.

Logistics, Transportation and Installation of Tanks

We take pride in having the expertise and capabilities to manage all the logistics involved in the installation and decommissioning of any small and large tank farm or temporary setup.

Vapour Tight Tanks

Vapour-tight tanks safely store volatile liquids. They are completely sealed to prevent the escape of harmful vapours and are often used for sour service applications, making them a crucial solution for storing crude oil, chemicals, and wastewater.

Frequently Asked Questions

Can I rent or purchase vapour-tight tanks from Benoit Rentals for temporary or long-term production?
Vapour-tight tanks (commonly called Tornado systems, Positive Pressure systems, or OSY tanks) serve as self-contained, turnkey surface production stations downstream of exploratory or temporary wellheads. Because our 400bbl package integrates fluid storage, a 500,000 BTU fire-tube heating system, automated gas measurement, and emergency shutdown instrumentation onto a heavy structural L-skid, it functions as a complete single-well battery. Operators can flow, heat, meter, and store production fluids immediately while flaring associated gas, avoiding the capital commitment of building permanent battery facilities before well potential is proven.
Yes, we manage all logistics involved in delivering, spotting, and securing your vapour-tight tank on lease. Because these 12-foot-diameter vessels require specialized transportation, Benoit Rentals coordinates provincial wide-load permits, arranges certified pilot escort vehicles, and dispatches dedicated winch or bed trucks directly from our Chauvin hub. Our skilled field drivers don’t just offload equipment at the gate—they winch and spot the skidded unit precisely onto your compacted lease pad, timber blocking, or rig mats, ready for mechanical piping tie-in.
Yes, we specialize in supplying complete, field-ready single-well battery packages downstream of the wellhead. Rather than dealing with multiple vendors for separate pieces of surface iron, you can source your API 620 vapour-tight tank, skid-mounted test separator, and matched flarestack system directly through Benoit Rentals. We supply units complete with vaulted meter runs, back-pressure regulators, fuel scrubbers, and emergency shutdown valves, giving your production team a cohesive, fully integrated temporary battery that saves weeks of facility planning and field assembly.
Every wellsite has unique pressure, fluid chemistry, and temperature profiles, which is why Benoit Rentals provides extensive pre-delivery customization. Before equipment dispatches from our Chauvin facility, our technicians can tailor your vapour-tight tank with specialized options including heavy-duty external urethane insulation, internal Enviroline 2405 chemical-resistant coatings, Catadyne instrument heaters, automated burner management systems, and sour-service Hawkeye gauge boards. We customize the vessel to your exact specifications so it integrates seamlessly into your site’s operational requirements without requiring modifications on lease.
With our main yard located in Chauvin right along the Alberta-Saskatchewan border, Benoit Rentals provides rapid mobilization across Wainwright, Provost, Macklin, Lloydminster, and surrounding basins. When a well test delivers unexpected volatile fluids or an existing battery vessel suffers an unexpected mechanical failure, our round-the-clock dispatch team coordinates immediate transport. We keep pre-inspected, hydrotested vapour-tight tanks and single-well battery packages staged and ready in our yard, ensuring critical containment arrives on your lease quickly to prevent costly production shut-ins.
Benoit Rentals provides comprehensive logistical support for the decommissioning and removal of temporary tank setups. Once your testing phase wraps up or permanent gathering lines are commissioned, our team coordinates the scheduling, equipment teardown, and heavy-haul transport back to our facility. While clients are responsible for having tanks drained and steamed clean of sour fluids and heavy sludge prior to highway travel, our logistics team assists with site demobilization timelines and ensures equipment is safely removed without disrupting ongoing lease activity.
Navigating provincial energy regulations can be demanding, but partnering with Benoit Rentals simplifies lease compliance. We provide full engineering data sheets, ASME pressure relief valve certifications, and volumetric calibration records required to satisfy Alberta Energy Regulator (AER) Directives 055, 060, and 017, as well as Saskatchewan Directives S-10 and PNG017. Our staff works closely with your regulatory and engineering teams, providing the exact documentation necessary to secure operating permits, satisfy environmental audits, and verify accurate casing gas accounting from day one.
Our service commitment continues long after the equipment is spotted on your lease. If your field operators encounter issues with automated burner systems, instrument freeze-offs during severe winter cold snaps, or need calibration assistance on Barton chart recorders, Benoit Rentals dispatches experienced technicians to assist. We maintain an extensive inventory of replacement valves, solenoids, thermocouples, and regulator parts at our Chauvin shop, ensuring rapid field troubleshooting and mechanical repairs that keep your temporary production battery operating safely with zero unbudgeted downtime.
We offer flexible, customer-focused rental structures designed to match dynamic oilfield timelines. Whether you require a vapour-tight tank for an intensive ten-day completions cleanout, a multi-month well evaluation program, or a multi-year battery lease, our terms adapt to your operational milestones. We offer transparent daily, weekly, and monthly rates that eliminate hidden fees. Furthermore, if a temporary testing project transitions into permanent production, we offer rent-to-own agreements where a portion of your rental investment applies toward purchasing the asset outright.
To streamline your procurement and reduce project freight costs, Benoit Rentals can bundle your vapour-tight tank with all necessary auxiliary surface rentals. We supply certified free-standing secondary containment systems with chemical-resistant liners engineered to fit our 400bbl units, interlocking rig mats for structural foundation support, diesel generators for site power, and mobile office trailers for on-site supervisors. Sourcing your complete lease package from one trusted supplier consolidates vendor coordination, simplifies billing, and ensures every piece of equipment works together flawlessly.
