Setting New Performance Standards
Xtreme Drilling and Coil Services offers some of the deepest-reach coiled tubing service units in the world. We continue to expand our XSR coiled tubing service fleet in response to the rapid growth of drilling activity in North American resource plays, customizing units for operations in deeper shale formations. We deployed the first of our new extended-reach units in early 2012 to the Eagle Ford Shale in South Texas. There, Xtreme has already begun setting new industry benchmarks for reach with larger-diameter coiled tubing.
Xtreme also has two coiled tubing service units deployed on a deep horizontal re-entry drilling project in the Middle East, where they have cut the operator’s drilling time in half and increased production six-fold.

Extended Reach for North American Resource Plays
The push for increasingly longer laterals continues in North American resource plays. Whether it’s for contractual leaseholds or to meet production targets, the end result is the same: the requirement for a service-based solution. Xtreme’s fleet has been designed specifically to provide coiled tubing services in the long-lateral wells being drilled in today’s unconventional shale plays. They provide superior reach for projects involving re-entry, coiled tubing cleanouts, fracturing, wellbore extensions, production logging, perforating, stimulations and other well servicing work.
These mast-style coiled tubing service units feature:
- 200,000 lb AC electric injectors
- Capable of transporting up to 23,500 feet of 2-5/8” coiled tubing
- Dual 1,000 HP quintaplex fluid pump/mixing units
- Mobile auxiliary support trailer/parts storage
- Data acquisition and fatigue modeling software
- 5,000-15,000 PSI well control equipment
In addition, all our XSR units are equipped with our proprietary electronic programmable logic controller (PLC) systems, including our X-Mill™ real-time milling software. This technology optimizes multiple parameters, allowing for smoother application of weight on bit while regulating the maximum differential pressure drop across the motor.
Improving Production
Key Well Parameters
- Formation: Eagle Ford
- Completion: 5.5" 23ppf to Surface
- Well Head Pressure: 2,200 psi
- TVD: 10,140 ft; PBTD: 18,040 ft
- Lateral Length: 7,440 ft
Challenge
- Removal of 8 flow-through plugs previously left in hole at depths unreachable by 2" coiled tubing
Results
- 8 plugs successfully milled out; PBTD reached
- 2,240 ft further reach in the lateral than 2"
- Post production doubled and surface flowing pressure increased by 40%
Reaching Further
* 2" and 2.375" are simulated reach results. 2.625" are actual results from job.
Key Well Parameters
- Formation: Eagle Ford
- Completion: 5.5” 23ppf to Surface
- Well Head Pressure: 2,500 psi
- TVD: 10,200 ft; PBTD: 19,834 ft
- Lateral: 9,100 ft
- Friction Factor: 0.27
Challenge
- Lateral length > 9,100 ft
- No GeoSteer in lateral
- PBTD could not be reached with traditional coiled tubing
Results
- PBTD reached successfully
- Utilization of 3.5” motor allowed for an increase in annular velocity and hole cleaning abilities
- Successfully milled out 36 plugs while significantly reducing motor stalls and traditional plug mill times
