Applications – Where a Mobile CTU Makes the Most Sense

A truck-mounted coiled tubing unit is not a one-size-fits-all tool—it's purpose-built for operators who move between wells frequently and need speed, not just capacity. Here’s where it truly shines:

Application Scenario	Why a Truck-Mounted CTU Works Best
Multi-well pad rotations	Multiple wells on the same lease—just drive 200 meters, rig up again, start the next job in less than an hour.
Remote or road-limited locations	Narrow tracks, soft ground, low bridges? A single truck passes where a trailer train can't go. NOV's field experience confirms: some locations just can’t handle bigger trailer-mounted units.
Routine well cleanouts and paraffin removal	When the job repeats every few weeks across dozens of wells, mobility equals profitability.
Velocity string installations in mature gas wells	Quick deployment for a job that takes hours, not days—truck arrives, works, and moves on.
Acidizing and nitrogen lift	Self-contained fluid pumping and nitrogen capabilities can be integrated or supplied from support units.
Fishing and light milling	Smaller-diameter milling operations where a full workover rig would be overkill.
Winter / Arctic campaigns	With the cold-weather package, the unit starts reliably and keeps operating in sub-freezing conditions.

Product Type Configurations

Configuration	Best For	Key Advantage
Single-Truck CTU	Operators running routine cleanouts and light workovers on shallow-to-moderate depth wells	Lowest cost, fastest rig-up, easiest transport—just one driver, one fuel bill, one piece to maintain
Split-Type CTU (Two-Truck)	Wells requiring deeper reach (3,000–5,000m+) or heavier pulling forces	Reel truck carries larger tubing capacity; injector/control truck handles BOP and well control—best of both worlds
6×6 or 8×8 Chassis Units	Off-road, muddy, or sandy wellsite access	Extra drive axles prevent bogging down in soft ground conditions where standard 6×4 trucks struggle
Arctic Package Units	Winter campaigns in Canada, Russia, Kazakhstan	Cold-start heaters, insulated hydraulic lines, low-temperature fluids and seals rated to −40°C

OEM Customization Solutions

We get it: your well conditions aren't the same as the operator down the road. That’s why our truck-mounted coiled tubing units start as engineering conversations, not just catalog orders.

What we customize:

• Capacity matching – We'll calculate your required pulling and snubbing force based on your well depth, tubing size, and expected wellhead pressure, then size the unit accordingly—not oversized, not undersized.

• Chassis selection – Specify your preferred truck brand (Sinotruk, Shacman, Mercedes, Kenworth, etc.), axle configuration (6×4, 6×6, 8×8), and engine type. We'll handle the chassis integration.

• Reel capacity optimization – You tell us your target depth in miles or meters, we size the reel to hold enough tubing plus 15% safety margin. No wasted transport weight from an oversized reel you’ll never spool fully.

• PTO and hydraulics tuning – We match pump sizes and flow rates to your preferred operating speeds and expected cycle counts. Custom wet kit layouts available.

• BOP configuration – Specify your brand preference (ours, OEM-provided, or your existing BOPs if they meet the pressure rating). We integrate for seamless well control.

• Climate adaptation – Arctic heaters, desert cooling packages, corrosion-resistant coatings for offshore or H₂S service. Just tell us where you operate.

• Control cabin upgrades – Data acquisition packages that log depth, weight, pump pressure, and tubing fatigue cycles; remote telemetry options for real-time job monitoring from your office.

• Fleet branding and paint matching – Your company colors and logos applied before delivery.

Why Choose SJ Petroleum Machinery?

🛞 Built by a Sinopec Subsidiary, Not a Trading House

When you buy from us, you're buying direct from a manufacturer with Sinopec's weight behind it. We hold the certifications that matter: API Q1, ISO 9001, and HSE management system certified. Our supply chains are Sinopec-grade, and our quality systems are audited annually.

🚚 Decades of Manufacturing Experience, Global Export Track Record

Founded in 1941, SJ has been supplying drilling rigs, workover equipment, and well intervention tools to oilfields across China—and today, to clients in South America, Africa, and the Middle East. When a coiled tubing unit leaves our gate, it's backed by decades of field engineering data from Sinopec's own operations.

🔧 Field-Proven Reliability in Harsh Environments

Our truck-mounted units have operated in the Middle Eastern desert at 50°C, in China's northwestern oilfields through −30°C winters, and on mountain roads that would strand lesser equipment. The arctic kit option is rated to −40°C—if your winter campaign demands cold-weather performance, we've built units that deliver it.

📋 Technical Documentation You Can Actually Use

Every unit ships with complete documentation: hydraulic schematics, wiring diagrams, parts breakdowns, and a maintenance manual written for field technicians, not engineers hiding in an office. Spare parts are cross-referenced with common industry part numbers where possible.

🔄 One-Stop Service Commitment

We don't disappear after delivery. Commissioning support, operator training at your site or ours, and spare parts logistics are all part of the package. If something goes wrong, we have engineers who can talk your team through troubleshooting—or travel to your location if needed.

💰 Competitive Pricing Without Quality Corners

Chinese manufacturing gets a bad reputation from low-end suppliers. We’re not that. Our pricing reflects efficient production and a streamlined supply chain, not shortcuts in materials or workmanship. You get a professionally engineered truck-mounted coiled tubing unit at a price that makes sense for your capital budget.

Frequently Asked Questions (FAQ)

Q1: What's the practical difference between a truck-mounted CTU and a trailer-mounted one?

A: Truck-mounted units integrate the power source (truck engine via PTO), reel, injector, and control cabin onto a single chassis—just one vehicle to drive and park. Trailer-mounted units require a separate towing vehicle and often have a separate power pack trailer. If you’re moving between wells daily and road conditions are decent, a truck-mounted unit saves significant time. If you need maximum tubing capacity for ultradeep wells and have good road access, a trailer-mounted unit might make more sense.

Q2: Can your truck-mounted CTU operate in severe cold?

A: Yes. The arctic kit includes engine block heaters, heated hydraulic fluid reservoirs, insulated hydraulic lines, low-temperature elastomers in seals and hoses, and cab heating for operators. Units with this package have been deployed at −40°C.

Q3: What tubing sizes does the unit handle?

A: Our standard configurations handle 1″ up to 3½″ O.D. coiled tubing. Larger diameters may require design modifications—let our engineering team know your requirements early.

Q4: Do you provide data acquisition and real-time monitoring?

A: Yes, as an upgrade option. We can equip the control cabin with sensors for depth, weight, pump pressure, tubing fatigue cycles, and other key parameters. Data logging and remote telemetry can be added to support real-time job monitoring from your central office.

Q5: How long does it take to rig up a truck-mounted CTU on location?

A: For a standard single-truck unit in favorable conditions: from arrival to first pipe movement, figure 45 to 60 minutes. This assumes the wellhead is accessible and no unexpected obstacles. Split-type two-truck configurations may take slightly longer.

Q6: What's your typical lead time?

A: Standard lead time is 90 to 150 days from order confirmation to shipment, depending on configuration and customization level. Rush orders may be accommodated if our production schedule permits—contact our sales team for current availability.

Q7: Can I supply my own BOPs or use existing well control equipment?

A: Yes, provided your equipment meets the required pressure rating and can be safely integrated with our hydraulic control system. We'll need specifications and certification documentation for compatibility verification.

Q8: Do you offer financing or leasing options for international customers?

A: We primarily sell direct, but we can work with third-party financing partners on a case-by-case basis. Contact our export team to discuss your procurement model.

Q9: How do I get a quote for a custom-configuration truck-mounted coiled tubing unit?

A: Send us your well parameters: maximum depth, tubing diameter you plan to run, expected wellhead pressure, preferred truck chassis, and whether you need single-truck or split-type. Also mention the operating environment (desert, arctic, offshore, etc.) and any target delivery date. We'll respond with a technical proposal and commercial quote within 7–10 business days.
