Dependable Wellsite Power Engineered for Remote Leases and Sour Gas Applications
At Benoit Rentals, we supply brand new, shop-reconditioned, and certified field-run Arrow C-Series single-cylinder gas engines for oil and gas production across Alberta and Saskatchewan. Renowned for their heavy cast flywheels, slow-speed reliability, and massive low-end torque, Arrow engines are the industry standard for driving pump jacks, progressive cavity pump (PCP) drives, water transfer pumps, and hydraulic power skids on off-grid leases.
Whether you need a temporary rental engine during an exploratory well test or are upgrading a permanent multi-well battery, Benoit Rentals provides turnkey, field-ready engine packages. Every unit is mounted on a heavy structural steel skid, complete with industrial clutches, matched drive sheaves, fuel regulators, and safety shut-off systems.
Built for Harsh Conditions: Sour Gas (H2S) & Raw Casing Fuel Optimization
One of the greatest operational advantages of an Arrow engine is its ability to run directly on produced wellhead gas. However, raw casing gas in east-central Alberta and western Saskatchewan frequently carries corrosive moisture, heavy condensates, and elevated levels of Hydrogen Sulfide (H2S). Burning untreated sour gas in a standard engine rapidly causes valve pitting, cylinder corrosion, and acidic crankcase oil breakdown.
Benoit Rentals solves this challenge by engineering sour-gas trim packages specifically tailored for sour service applications:
• H2S-Tolerant Engine Metallurgy: Equipped with hardened Stellite valves, premium alloy valve seats, corrosion-resistant fuel lines, and sour-service carburetors designed to withstand continuous H2S exposure.
• Integrated Fuel Scrubbers & Liquid Pots: Every package features a dedicated fuel gas scrubber and coalescing filter to knock out entrained water and heavy hydrocarbon liquids before gas reaches the carburetor.
• Positive Crankcase Ventilation: Specialized crankcase breathers and oil management systems prevent sour blow-by gases from condensing into sulfurous acid in the oil sump.
• Zero Grid Dependency: Eliminate the massive capital cost of running three-phase utility power to remote leases or the endless expense of trucking in commercial propane—safely monetize your available casing gas to power your production.
Available Arrow Engine Models
• Arrow C46 Engine: Compact, continuous-duty power (~10–15 HP). Ideal for shallow pumping units, small stroke rod pumps, chemical injection skids, and fluid transfer.
• Arrow C66 Engine: The workhorse of the prairie patch (~15–20 HP). Engineered for medium-depth beam pump jacks, rod pumps, and light compressor drives.
• Arrow C96 Engine: Maximum heavy-duty torque (~20–30 HP). Designed for deep-set rod pumping units, heavy crude lifting, and continuous high-load applications.
Frequently Asked Questions
Can I rent or purchase new, reconditioned, and field-run Arrow engines from Benoit Rentals?
Benoit Rentals offers complete flexibility with brand new, fully shop-reconditioned, and certified field-run Arrow C-Series engines available for both rent and outright purchase. If you need temporary mechanical drive power during an extended well evaluation or pump jack workover, our rental agreements keep capital expenditures low. For established production wells across Alberta and Saskatchewan, purchasing a brand new or completely rebuilt Arrow C46, C66, or C96 engine provides a durable, cost-effective power source backed by our mechanical warranty and parts support.
Can Benoit Rentals configure Arrow C-Series engines to run reliably on sour lease gas (H2S)?
Yes, we specialize in outfitting and trimming Arrow engines specifically to handle sour lease casing gas with elevated H2S concentrations. To protect the engine from corrosive sulfide attack and premature mechanical failure, our shop configures units with sour-gas carburetors, hardened Stellite valves and seats, stainless steel fuel piping, and specialized crankcase ventilation. We also pair engines with fuel gas scrubbers to strip moisture and heavy condensates, allowing operators to burn available wellhead gas safely without having to truck in expensive commercial propane.
How do I determine whether an Arrow C46, C66, or C96 engine is right for my pump jack or pumping unit?
Selecting the proper Arrow engine depends on your downhole pump depth, rod string weight, stroke length, and pump jack gear reducer rating. Our technical team works directly with your production engineers to analyze your pumping unit dynamics. Typically, the C46 handles smaller shallow pumping units and low-horsepower fluid transfer pumps, the C66 is ideal for mid-depth beam pumps and progressive cavity pumps (PCPs), and the heavy-duty C96 delivers the continuous slow-speed torque required for deep, heavy-load rod pumping wells.
Does Benoit Rentals supply complete skidded engine packages with clutches, sheaves, and fuel gas scrubbers?
Rather than sourcing fragmented drive components from multiple vendors, Benoit Rentals supplies fully integrated, turn-key Arrow engine packages ready for immediate field installation. Our packages arrive mounted on heavy-duty structural steel oilfield skids and come equipped with heavy industrial clutches (Twin Disc or Rockford style), matched drive sheaves, belt guards, and fuel gas regulators. We also incorporate fuel scrubbers, exhaust silencers, and safety kill switches, ensuring your crew can rig in and belt up to the pump jack gearbox in hours.
What reconditioning and testing process does Benoit Rentals perform before dispatching an engine?
Every reconditioned Arrow engine leaving our Chauvin mechanical facility undergoes an exhaustive rebuild and quality-assurance process. Our experienced heavy-duty mechanics completely disassemble the engine to inspect crankshaft tolerances, install new cylinder sleeves, pistons, rings, and rod bearings, and recut valve seats to factory specifications. Each rebuilt unit is then shop-mounted, fluid-tested, and test-run under load to verify oil pressure, ignition timing, and governor stability, ensuring you receive an engine that performs with brand-new reliability on your lease.
Can Benoit Rentals deliver, spot, and align the engine directly on our lease?
Benoit Rentals coordinates dedicated transport and field spotting directly from our central Chauvin operating yard to lease sites across Alberta and Saskatchewan. Our transport fleet includes winch-equipped picker and bed trucks capable of loading, hauling, and offloading heavy engine skids safely onto your lease pad or pump jack sub-base. Our experienced drivers assist with spotting the engine skid in square alignment with your pumping unit sheaves, significantly simplifying belt tensioning and final mechanical tie-in for your field maintenance crew.
Does Benoit Rentals stock replacement parts and provide field service or rebuilds for existing customer engines?
We understand that unexpected engine downtime halts oil production and inflates operating costs. Benoit Rentals maintains a substantial inventory of genuine Arrow replacement parts at our Chauvin shop, including carburetors, magneto ignitions, valves, gasket sets, oil pumps, and clutch plates. In addition to supplying replacement parts, our mobile service mechanics can be dispatched to your lease to diagnose ignition issues, rebuild top ends, or pull and swap worn engines, ensuring your pumping units stay running smoothly year-round.
What fuel supply conditioning or scrubbers does Benoit Rentals provide to protect engines from liquid carryover and high H2S?
Raw casing gas straight from the wellbore often contains high moisture, foaming liquids, and corrosive H2S that can foul spark plugs, dilute crankcase oil, and ruin engine valves. To prevent fuel-related shutdowns, Benoit Rentals packages its Arrow engines with dedicated fuel gas scrubbers, coalescing filter pots, and secondary pressure regulators. These conditioning units effectively knock out entrained liquids and heavy hydrocarbon condensates, delivering clean, dry, and pressure-regulated gas to the carburetor even during sudden wellhead liquid surges.
What are Benoit Rentals' rental terms for temporary pumping operations versus long-term production?
Oilfield development schedules often evolve unpredictably, which is why Benoit Rentals offers fully adaptable rental terms without locking operators into rigid long-term commitments. Whether you need an engine to power a temporary beam pump during a 30-day well test or require multiple units for a seasonal production campaign, we provide competitive daily, weekly, and monthly rates. If an exploratory well proves commercially viable, we also offer rent-to-own programs that credit a portion of rental payments toward permanent ownership.
How do Benoit Rentals' Arrow engine packages handle extreme winter cold and remote off-grid conditions?
Arrow slow-speed, heavy-flywheel engines are legendary across Western Canada for their ability to operate independently of the electrical grid in brutal minus-40-degree winters. Benoit Rentals equips its rental and sales packages with heavy-duty cold-weather features, including 120V engine block heaters, synthetic low-temperature crankcase oils, and dependable 12-volt electric starter or air/gas starter systems. Combined with the massive kinetic inertia of their counterbalanced flywheels, our Arrow engines power through heavy cyclic rod pump loads without stalling during severe prairie blizzards.
