Product Types We Offer for Low-Temperature Environments

We are not a one-product company. Our low-temperature portfolio covers complete drilling and well-service ecosystems:

1. Low Temperature Land Drilling Rigs (AC-DC / AC-VFD) – Diesel-electric or grid-powered for Siberia, Western Canada, and Alaska.

2. Low Temperature Track-Mounted & Wheel-Rail Drilling Rigs – Optimized for cluster drilling in continuous permafrost.

3. Low Temperature Truck-Mounted Drilling & Workover Rigs – Fast mobilization for remote well-servicing and workovers.

4. Low Temperature Modular Skid Rigs – Helicopter-transportable modules for inaccessible arctic locations.

5. Low Temperature Coiled Tubing Units – For sub-zero well intervention, nitrogen lifting, and sand cleanout.

6. Low Temperature Wellhead & BOP Control Systems – Hydraulic and electric systems with low-temp-rated seals and heating jackets.

7. Low Temperature Solids Control Systems – Tank-integrated heating and insulation packages for mud recycling at -45°C.

Application Fields

🌨️ Arctic & Sub-Arctic Land Drilling

Targeting the Siberian basins (West Siberia, East Siberia), Timan-Pechora, Northern Canada (Mackenzie Delta, Northern Alberta), and Alaska’s North Slope. Our low-temperature drilling solutions are actively operating in the Russian Arctic Circle and have been successfully delivered to Rosneft’s ZJ40DB low-temperature rig projects.

🧊 Offshore Arctic Platforms

Our offshore-rated low-temperature drilling packages meet the dual demands of ice-strengthened platform operations and extreme cold winterization. Capable of working in conjunction with ice-resistant jack-up platforms and bottom-supported structures.

🏔️ High-Altitude & High-Latitude Mountain Drilling

Cold-weather performance is not just about latitude — it is about altitude. Our equipment supports operations in the Kunlun Mountains, Andes, and Himalayan foothills, where temperatures drop below -35°C regardless of the season.

🧪 Permafrost Coring & Geothermal Exploration

Specialized lightweight low-temperature rigs for permafrost coring, gas hydrate research wells, and deep geothermal exploration in cold climates.

Why Choose SJ PETROLEUM MACHINERY Co., Ltd.?

🏢 Backed by Sinopec — The Strength You Can Trust

As a wholly-owned subsidiary of Sinopec Oilfield Equipment Corporation, we operate with the technical depth, financial stability, and global supply chain reach of one of the world’s largest energy companies.

✅ Proven Export Track Record to Harsh Environment Markets

Our equipment has been successfully exported to Russia, Kazakhstan, the Middle East, and South America under some of the most punishing field conditions. We have delivered 11 sets of low-temperature drilling rigs to Russia and been recognized as a preferred low-temperature drilling rig supplier in that market.

🧪 National-Level Testing Means No Guesswork

Our national-level low-temperature impact testing lab is not a marketing phrase — it is the real facility where every critical load path is validated before the rig ships to your site. We know what our steel does at -45°C because we have tested it.

🔧 End-to-End Integrated Service

We do not just sell hardware. We provide:

• Pre-sale engineering consultation and well planning support

• On-site installation supervision and commissioning

• Training for local crews (cold-weather operation and emergency procedures)

• Long-term spare parts supply and technical hotline support

🌏 Global Brand Recognition

Our products carry respected brand names — SJPETRO, KINGDREAM, SJS — that are recognized across key oil-producing regions. We have active business relationships with Saudi Aramco, Kuwait Oil Company, PDO Oman, and Rosneft.

Frequently Asked Questions (FAQ)

Q1: What is the lowest ambient temperature your low-temperature drilling equipment can handle for continuous operation?

A: Our standard low-temperature drilling rigs are designed for continuous operation down to -45°C. Storage capability extends to -60°C without damage. We have also delivered customized projects capable of intermittent operation down to -50°C in the Russian Arctic. Contact our engineering team for site-specific thermal modeling.

Q2: Do your low temperature drilling rigs meet GOST certification requirements for Russian and Eurasian markets?

A: Yes. All our low-temperature equipment intended for the Russian market is designed and manufactured to meet GOST 12.2.141-99, GOST 16293-89, and PB 08-624-03 safety requirements. Our products have cleared Russian customs and field acceptance multiple times.

Q3: What is your typical lead time for a complete low-temperature drilling rig?

A: Standard lead time for a complete land drilling rig is approximately 8-10 months from order confirmation to FOB port shipment, depending on the rig size and customization requirements. We maintain a dedicated green channel for low-temperature component sourcing to ensure timely delivery for seasonal drilling windows.

Q4: How do you ensure the reliability of electronic and control systems in extreme cold?

A: All control cabins and electronic enclosures are equipped with thermostatically controlled electric heating systems and low-temperature-rated internal components. Critical sensor suites are point-heated. We use industrial-grade electronics rated for -40°C operation with de-rating margins for -45°C field conditions.

Q5: Do you offer modular low-temperature drilling rigs that can be transported by helicopter?

A: Yes. Our helicopter-portable low-temperature rigs break down into sling-loadable modules that can be moved by medium-lift helicopters (e.g., Mi-17 class) for true remote-area access. The module design includes all necessary heating interfaces, so you can reassemble, connect utilities, and start drilling quickly.

Q6: Can you customize low-temperature solutions for a specific field condition that is not covered by your standard specifications?

A: Absolutely. Our engineering team specializes in site-adapted designs. We will conduct a detailed review of your temperature profiles, logistics constraints, power availability, and well program, then propose a custom engineering package tailored to your specific needs.

Q7: What after-sales support do you provide for international buyers?

A: We provide a standard 12-month warranty from commissioning. On-site technical representatives are available for the initial rig-up and commissioning. We maintain an international spare parts inventory and operate a 24/7 technical support hotline. For key markets, we have local field service presence.
