Primary Applications & Product Types

Our specialized rigs are not one-size-fits-all. We deliver specific solutions for the following critical market segments:

1. Ultra-Deep & High-Pressure High-Temperature (HPHT)
Designed to reach 9,000+ meters, these heavy-duty drilling rigs feature reinforced mast structures, high-capacity draw works (over 3000hp), and advanced blowout preventer (BOP) handling systems.

2. Offshore & Island Drilling
Our modular offshore drilling rig solutions feature low-center-of-gravity designs that are ideal for Tender Assisted Drilling (TAD) on jack-up platforms. We offer smaller footprint substructures without compromising on vertical lift capacity.

3. Directional & Extended-Reach Drilling
For horizontal wells, our rigs come equipped with optional Top Drive Systems (TDS) and digital torque feedback, allowing the driller to maintain the exact weight-on-bit (WOB) required for challenging directional trajectories.

4. Geothermal or Specialized Shale
These application-specific land rigs feature smaller mobile footprints and quick rig-up capabilities for shorter-radius drilling but maintain high casing running capacity.

OEM Customization Solutions: Built for Your Specific Drilling Program

Because "Specialized" is in our DNA, we understand the need for unique modifications. If a standard catalog rig isn't the perfect fit for your project, our OEM Drilling Rig Solutions team steps in to tailor the equipment to your operational specifics:

• Custom Skid & Substructure: Do you need a specific footprint to fit inside an existing pad or a 40-foot container load? We engineer the skidding, jacking, or lifting system to your exact logistics limitations (e.g., max box size for shipping to remote fields).

• Voltage & Power Architecture: We can calibrate the AC VFD systems to match your local grid (50Hz/60Hz, 690V, 110V), or engineer standalone power generation packages that run on diesel or gas.

• Regulatory Compliance Packages: Need a rig that meets NORSOK for the North Sea or specific ANSI/API classifications for a specific country? We provide the local documentation and material certification required for smooth customs and field approval.

• Specific Automation Integration: We can pre-install your preferred automated pipe handling systems or integrate your customized well logging hardware into the drill floor.

FAQ

Q: What is the lead time for a specialized deep-well drilling rig?
A: For specialized configurations like an Arctic winterized rig or an Ultra-Deep rig, lead times generally range from 6 to 9 months, depending on the complexity of the OEM features and component sourcing required.

Q: Does Sinopec provide class certification for offshore rigs?
A: Yes. We work closely with major classification societies (DNV, ABS, BV, CCS) to certify your specific modular platform skid or jack-up rig design for offshore safety compliance.

Q: How do you handle voltage compatibility for different countries?
A: Our AC VFD systems are highly adaptable. We can design your rig's power infrastructure to match existing local grids or build independent step-up/down transformers into the final spec.

Q: Can these rigs be shipped in standard containers?
A: Absolutely. Our skid-mounted specialized drilling rigs and modular derrick designs are engineered for disassembly. We can ship the total package in standard 40ft containers to virtually any port in the world.

Q: What is your service warranty for these units?
A: We provide a comprehensive 18-month warranty from the date of shipment, covering major components like the draw works, electric motors, and mast structures. Long-term service agreements are also available.
