Applications – From Desert to Deep Sea

Our drilling rigs are deployed across the globe in diverse operating environments:

Onshore Oil & Gas Exploration – Conventional and unconventional reservoirs, including tight gas and shale formations. Our rigs have drilled thousands of meters in China’s major oilfields and international projects.

Offshore Platforms – Fixed platform and floating platform drilling and workover equipment. We supply complete offshore drilling packages including BOP handling systems and subsea control integration.

Ultra-Deep Well Drilling – Our ZJ90DB 9,000-meter ultra-deep drilling rigs have been successfully deployed in Northwest China and Kuwait, drilled to maximum depths exceeding 9,270 meters, creating multiple engineering records.

Desert Operations (Middle East & North Africa) – With 28 rigs currently operating in Kuwait alone and ZJ50DB rigs shipped to North Africa, our equipment is battle-tested in high-temperature, sandstorm-prone environments. As of late 2024, overseas orders had grown by 50%, with the Middle East market contributing over 50% of this growth.

Arctic & Low-Temperature Regions – Siberia and other northern regions – our GOST-certified low-temperature truck-mounted rigs are designed for extreme cold reliability.

Geothermal & Water Well Drilling – Specialized lightweight rigs for renewable energy and water resource development.

Frequently Asked Questions (FAQ)

Q1: What certifications do your drilling rigs hold?

A: Our drilling rigs are manufactured in compliance with API 4F, 7K, and 8C standards and carry the API monogram. We also maintain ISO9001, ISO14001, HSE, GOST (Russia), and CE certifications for applicable export markets. Full documentation is available upon request.

Q2: What is your typical delivery lead time?

A: Standard lead time ranges from 6 to 12 months from order confirmation to shipment, depending on the rig model, custom specifications, and current production queue. Rush orders can be accommodated with prior arrangement.

Q3: Do you provide onsite commissioning and training?

A: Yes. Our service engineers travel with each major rig shipment to oversee onsite assembly, commissioning, and initial operation. We also provide comprehensive training programs for client crews, either at our facility in Jingzhou or onsite at your location.

Q4: Can you customize a drilling rig for a specific depth or terrain?

A: Absolutely. We specialize in custom engineering. Our team works from your well plan to determine optimal rig specifications – including depth rating, mast height, substructure configuration, power system, and climate adaptation features (desert cooling, arctic heating, etc.).

Q5: What is your spare parts and after-sales support policy?

A: We maintain a global spare parts inventory and can ship critical components within 48–72 hours for most standard parts. Emergency technical support is available 24/7 via phone and video conferencing. We also offer scheduled maintenance contracts for large fleet operators.

Q6: How does your pricing compare to other major drilling rig manufacturers?

A: We offer competitive pricing due to Sinopec’s integrated supply chain and manufacturing scale. On a like-for-like specification basis, our rigs typically cost 15–25% less than comparable Western-manufactured equipment while maintaining equivalent or superior quality standards.

Q7: Do you manufacture offshore drilling equipment?

A: Yes. We supply drilling and workover packages for fixed platforms and are actively developing floating platform (deepwater) equipment including BOP handling systems and subsea integration.

Q8: Can you provide references or case studies from existing customers?

A: Certainly. We can share non-confidential case studies and reference contacts from satisfied customers in the Middle East, North Africa, Russia, and Southeast Asia. Please contact us directly to discuss your specific interest areas.

Q9: What payment terms do you offer?

A: Standard payment terms are negotiable based on order size and customer credit history. Typically we work with Letter of Credit (L/C), Telegraphic Transfer (T/T) with milestone payments, or other arrangements as mutually agreed.

Q10: How do I request a quotation or technical proposal?

A: Use the contact form below or email our sales team directly. Please provide your target drilling depth, terrain conditions, power preference (diesel/electric), and any specific certification or compliance requirements. We will respond within 48 hours with an initial technical assessment and quotation timeline.
