FAQ – Low Temperature Drilling Rig

Q1: What is the difference between "low temperature drilling rig” and "arctic drilling rig” – are they the same?

A: They are related but not identical. A low temperature drilling rig (as defined by our industry design standard) is typically rated for -45°C operation and -60°C storage. An "arctic drilling rig” may be rated for even lower temperatures (-50°C or -55°C) and often includes additional features like full walkway enclosures, enhanced redundancy in heating systems, and ice‑resistant hull designs for offshore operations. Our ZJ40DB low temperature rigs are fully capable of year‑round operation in the Russian Arctic at -45°C. For regions requiring -50°C or lower, we offer an enhanced Arctic package with additional insulation, increased heating capacity, and specialized low‑temperature steel. Contact us with your specific temperature requirements.

Q2: What is the lowest temperature your low temperature drilling rig can operate at?

A: Our standard low temperature drilling rig is rated for -45°C continuous operation and -60°C storage. We have verified this rating through field deployment in Western Siberia and laboratory testing in our own -70°C low temperature impact facility. For customers requiring operation at -50°C or lower, we offer the Arctic Plus upgrade with enhanced heating capacity and additional insulation.

Q3: How many low temperature drilling rigs has SJ Petro exported to Russia?

A: SJ Petro has exported 11 complete ZJ40DB low temperature drilling rigs to Rosneft, Russia's largest state‑owned oil company, under a single project contract. The first six rigs are currently drilling in the Samara Oblast region. In addition to these, we have also exported low temperature truck‑mounted drilling rigs to Orenburg Drilling Company, ZJ40 truck‑mounted cold‑weather drilling rigs certified for Russia. Our total low temperature equipment exports to Russia span drilling rigs, coiled tubing units, fracturing skids, and other supporting equipment.

Q4: Does the low temperature drilling rig comply with GOST certification for Russian operations?

A: Yes. All SJ Petro low temperature drilling rigs are designed to meet GOST 12.2.141-99 (occupational safety standard for surface drilling equipment) and ПБ 08-624-03 (Russian petroleum industry safety regulations). We provide full documentation packages for local certification, and we have experience securing permits for rigs delivered to the Russian market. Third‑party certification to ABS, DNV, or other international class societies is available at customer request.

Q5: Can the low temperature drilling rig be used for cluster pad drilling in the winter?

A: Yes. The low temperature drilling rig is available with a hydraulic walking system or rail‑mounted system, both fully winterized with heated cylinders, low‑temperature hydraulic fluid, and insulated hoses. When equipped with walking capability, the entire rig can be moved between wellheads on a pad without dismantling – a critical advantage when winter drilling windows are short. Our rail‑mounted configuration is particularly popular for cluster well pads in Russia and Canada, providing reliable year‑round operation.

Q6: What heating systems are used to keep the rig functional at -45°C?

A: The low temperature drilling rig incorporates a multi‑zone heating architecture with redundant circuits:

• Electric block heaters on all engines

• Heat‑traced suction and return lines for hydraulic systems

• Enclosure heaters (electric or steam) for driller cabins, generator rooms, and BOP control units

• Refrigerated air dryers with heat‑traced drains

• Anti‑ice coatings and non‑slip surfaces on walkways and access areas

All heating circuits are thermostatically controlled with backup capacity – if one heater fails, the redundant system maintains temperature until repairs can be made.

Q7: What is the typical delivery lead time for a low temperature drilling rig?

A: 6‑9 months from order confirmation for a standard ZJ30‑LT to ZJ70‑LT low temperature rig. The lead time includes engineering verification, material procurement, fabrication (with low‑temperature welding procedures), assembly, full system testing (including cold‑start validation), and export packing.
