1. **Double-Engine Compound Power System**
Mature double-engine compound power system with two imported CAT engines paired with Allison transmissions. Provides redundant power — if one engine needs maintenance, you can keep operating on the other. Delivers the horsepower needed for the heaviest workover and drilling operations.
2. **14×8 Heavy-Duty Chassis**
Purpose-built 14×8 workover rig chassis — the largest in our lineup. Designed to handle the extreme weight of the tall mast, high-capacity drawworks, and dual-engine power system, with excellent weight distribution for on-the-road mobility.
3. **Parallelogram Folding Substructure**
Parallelogram-type folding substructure with stable construction and easy installation. Rig up quickly on location while providing a solid working platform for heavy-duty operations.
4. **1,800 kN Maximum Hook Load**
Industry-leading 1,800 kN maximum static hook load for a truck-mounted workover rig. Handles the heaviest pulling loads on ultra-deep wells.
5. **Dual-Purpose Heavy-Duty Rig**
When configured with substructure and supporting accessories, this rig can handle both heavy workover operations and deeper drilling/completion work — maximizing your equipment utilization on major projects.
Applications
The 750HP workover rig is engineered for ultra-deep well operations and the heaviest intervention work. It's the most powerful mobile workover rig in our lineup — built for the toughest jobs on major onshore oil fields.
- Primary use: ultra-deep well workover, heavy fishing operations, and major completion work on deep producers.
- Suitable for both heavy workover operations and deeper drilling/completion work when configured with substructure.
- Deployed by large service companies on the biggest onshore oil fields across the Middle East, Russia, and Central Asia.
The Pinnacle of Mobile Workover Rigs
When you reach this horsepower class, you're approaching the limits of what a truck-mounted rig can do. Beyond this point, you're looking at skid-mounted drilling rigs that require weeks to rig up and move.
The 750HP workover rig gives you drilling-rig-level pulling power — 1,800 kN of hook load — while retaining the mobility and fast rig-up times that make workover rigs so cost-effective. The double-engine compound power system means you have redundancy: if one engine needs service, you can keep working on the other.
This is the rig you deploy when the alternative is bringing in a full drilling rig for a workover job — which would cost several times more in mobilization and rig-up time. For large service companies with deep well operations in their area, the 750HP rig is a competitive advantage.
Choosing the Right Workover Rig Size
For ultra-deep wells (6,000m+) or operations involving extremely heavy fishing, milling, and completion work, the 750HP unit delivers the maximum power in our mobile workover lineup.
If your wells are shallower and operations are less demanding, the 650HP Workover Rig offers a more cost-effective solution. For even deeper drilling work beyond what a mobile rig can handle, you'll need to move up to our skid-mounted drilling rigs.
FAQs
Q: What makes this rig's power system unique?
A: It uses a mature double-engine compound power system with two CAT engines and Allison transmissions — providing redundant power and the high horsepower needed for ultra-deep well operations.
Q: What's the maximum hook load?
A: The maximum static hook load is 1,800 kN — the highest in our mobile workover rig lineup.
Q: What chassis is used?
A: This rig is built on a 14×8 heavy-duty workover rig chassis — the largest chassis we use for mobile workover rigs.
Q: What's the difference between this and smaller rigs?
A: The 750HP class represents the upper limit of mobile workover rigs. It offers drilling-rig-level pulling power with workover-rig-level mobility — ideal for ultra-deep well operations.
