Well Intervention
& Coiled Tubing

Reliability to the Core, Tailored to Your Needs

Stewart & Stevenson has manufactured well intervention equipment since 1989, and we were also an early leader in manufacturing coiled tubing units (CTU). With continued technological advancements, today’s CTUs feature the highest pull-to-weight injector heads, steel tubing reels, and control cabins where operators can easily and efficiently direct all well site operations.

Well Intervention

Well intervention systems can be tailored to your specific needs and geographic locale and are completed with nitrogen units and high-pressure fluid pumping units. Applications include workover, cleanouts, jetting/lifting, acid spotting, fishing, frac through coil, drilling, and logging. Products can be certified for areas that require Zone 2, ATEX, NORSOK, and CE compliance.

Coiled Tubing Units

We offer land, offshore, trailerized and masted CTUs, injector heads, and reels and reel trailers. Both land and offshore units are configured in standard trailer, truck, skid-mounted, or masted versions and can be tailored to meet your specific project needs.
