Applications

Our double-well drilling rig is proven in demanding environments worldwide:

• Offshore Jack-up & Semi-submersible Platforms – dual-well layout for batch drilling and simultaneous operations (SIMOPS).

• Onshore Multi-well Pad Drilling – shale gas, tight gas, coalbed methane, and conventional oil fields.

• Cluster Drilling in Mature Fields – maximize recovery from limited surface area.

• Platform Infill Drilling – drill infill wells without interrupting production from existing wells.

• Arctic and Remote Locations – reduce logistics and support costs with fewer rig moves.

For offshore jacket applications, single-conductor double-well technology has achieved 66.6% efficiency improvement and 40.3% shorter drilling cycles. For land pads, multi-well rigs reduce footprint and increase drilling density without sacrificing performance.

Frequently Asked Questions (FAQ)

Q1: What is the difference between a dual-well drilling rig and a conventional single-well rig?
A dual-well drilling rig has two independent drilling centers on a single rig structure. It can drill two wells sequentially without moving the rig (batch drilling) or perform parallel operations (e.g., drilling one well while running casing on the second). A conventional single-well rig can only drill one well at a time and must be moved between well locations.

Q2: Is the dual-well drilling rig suitable for offshore platforms?
Yes. Our double-well rig is specifically designed for offshore jack-up and fixed platforms. Dual-well layouts reduce platform space requirements and allow simultaneous drilling and completion operations, significantly reducing total project time.

Q3: How much cost savings can I expect?
Field applications of dual-well technology have achieved 30% cost reduction per well for offshore single-conductor double-well drilling and up to 66.6% efficiency improvement. Savings come from reduced rig move time, shared infrastructure, and parallel operations.

Q4: Do you offer customized specifications?
Absolutely. We provide customized drilling rig solutions including:

• Different well center spacing

• Higher hook load for deeper wells

• Special material grades for H2S service

• AC-VFD vs. DC drive systems

• Climate-specific features (arctic, desert, tropical)

Q5: What certifications do your rigs carry?
Our dual-well drilling rigs are designed and manufactured in compliance with API 4F, 7K, 8C, and ISO 9001. Safety systems meet international offshore and onshore standards.

Q6: Can you provide installation and training?
Yes. We offer full commissioning, onsite installation supervision, and comprehensive training for your crew—both onsite and at our facilities in China.

Q7: What is your typical lead time for a dual-well drilling rig?
Lead time depends on specifications, typically 8–12 months from order to delivery for a complete rig package. Custom engineered components may extend lead time. We recommend contacting our sales team for a project-specific schedule.

Q8: Do you sell spare parts and provide technical support outside China?
Yes. We maintain a global spare parts inventory and work with local agents in major oil-producing regions. Our technical support team is available 24/7 for remote troubleshooting and onsite service.
