Innovation & Technology Advantages

Live Well Intervention Without Well Killing

Unlike conventional wireline or threaded tubing, coiled tubing allows the operator to pump fluid or circulate while moving the pipe in and out of the well. The continuous design eliminates connection time, reduces leak paths, and enables live well intervention without killing the well.

High‑Strength, Fatigue‑Resistant Tubing (CT55 – CT110)

Coiled tubing undergoes severe bending fatigue every time it passes over the gooseneck and through the injector. SJ Petro's API 5ST tubing uses specially formulated low‑carbon alloy steel with excellent fatigue resistance properties. Grades are available from CT55 (55,000 psi yield) up to CT110 (110,000 psi yield) and beyond, for deep HP/HT wells.

Precision Tension Control – Prevents Pipe Damage

The drive system of the reel is designed to keep the coiled tubing in tension between gooseneck and the reel while running in or retrieving from the well. Tension sensors integrated into the level‑wind mechanism provide real‑time feedback, preventing over‑spooling or slack that could cause pipe buckling or crushing.

Powered Level‑wind for Even Spooling

Automatic level‑wind mechanism ensures each layer of tubing is laid evenly across the reel drum, preventing cross‑over damage that creates weak points for future fatigue failure.

Arctic‑Rated Engineering

SJ Petro's low‑temperature coiled tubing reels are engineered for continuous operation down to -45°C, with storage capability to -60°C. Includes low‑temperature steel, cold‑hardened hydraulic seals, heated control enclosures, and low‑pour‑point hydraulic fluids.

SOFElink® Intelligent Control Platform

SJ Petro's independently developed control system uses IoT and cloud technology for real‑time curve monitoring, predictive maintenance alerts, fleet tracking, and wireless centralized control. Operators can monitor pressure, depth, tension, and circulation from a single HMI.

API 5ST, 16B & 16ST Compliance – Full Documentation

All SJ Petro coiled tubing reels are designed and manufactured in accordance with API Spec 5ST (coiled tubing), API Spec 16B (coiled tubing, snubbing, and wireline equipment), and API 16ST (well control equipment assembly and operation). Complete certification documentation — material test reports, dimensional inspection records, NDT reports, and certificates of conformance — is included with every shipment. Third‑party inspection by BV, SGS, DNV, or ABS is welcome at any stage of manufacturing.

Coiled Tubing Reel & CTU Applications

Well Intervention (Live Well Operations)

Live well intervention is the primary application for coiled tubing. Coiled tubing can be used in a wide variety of well control applications, requiring a small crew complement as well as mobile systems. Applications include well cleanouts, acidizing, milling operations (particularly in high‑pressure environments), scale and paraffin removal, fishing parted pipe, gas lift valve installation and retrieval, and well control recovery.

Underbalanced Drilling (CTD – Coiled Tubing Drilling)

Coiled tubing drilling (CTD) technology is increasingly used for geosteering and slimhole drilling, allowing continuous circulation for pressure control and thermal management, plus real‑time wireline telemetry.

Completion & Perforation

Coiled tubing is widely used for perforating work strings, well completion operations, logging, and clean‑out prior to installation of production equipment. The continuous design enables rapid mobilization compared to jointed pipe.

CO₂ Injection & Carbon Capture

As part of the energy transition, coiled tubing technology is finding new applications in carbon capture and storage (CCS). 2025 papers included a discussion of a first‑time technology breakthrough of CO₂‑injection pumping using coiled tubing for Project Greensand in Denmark.

Arctic & Remote Land Drilling (Siberia, Canada, Alaska)

In extreme cold and remote areas where conventional workover rigs are impractical, coiled tubing units with Arctic‑rated reels provide fast, cost‑effective well intervention. Low‑temperature engineering is critical for continuous operation at -45°C.

Extended‑Reach & Horizontal Laterals

As horizontal laterals stretch beyond three miles, coiled tubing operators face friction, drag, and buckling that can prevent reliable access to the toe. High‑strength coiled tubing with optimized reel tension control addresses these reach barriers.

Offshore Platform & Subsea Well Intervention

Coiled tubing units are deployed on offshore platforms for live well intervention without killing the well — a critical advantage in high‑cost, high‑risk marine environments. Special marine‑grade finishes and corrosion‑resistant materials are available.

Hydraulic Workover (HWO) Support

When a hydraulic workover unit requires assistance with pumping and circulation while running or pulling pipe, a coiled tubing unit can be integrated as part of the service spread, providing clean‑out and milling capability before or after the HWO operation.

Frequently Asked Questions (FAQ)

Q1: What is the difference between a coiled tubing reel and a conventional tubing handling system?

A: A coiled tubing reel stores a long, continuous steel pipe (coiled tubing) that can be inserted into the wellbore without threaded connections, enabling faster deployment and retrieval compared to conventional tubing. In conventional systems, pipe must be connected and disconnected in stands of 2 or 3 joints, slowing down operations and creating additional leak paths. Because no threaded connections are required, coiled tubing enables much faster well intervention with a smaller crew complement.

Q2: What API standards do your coiled tubing reels comply with?

A: SJ Petro coiled tubing reels are designed and manufactured in compliance with API Spec 5ST (coiled tubing manufacturing and testing), API Spec 16B (2025 edition) (coiled tubing, snubbing, and wireline well intervention equipment), and API 16ST:2009 (coiled tubing well control equipment assembly and operation).

Q3: What is the maximum tubing length per reel?

A: Maximum single reel tubing length is up to 8,000 metres (approx. 26,200 ft) depending on tubing outer diameter, wall thickness, and grade. Common commercial lengths exceed 30,000 ft for certain diameters and grades.

Q4: What tubing steel grades are available?

A: SJ Petro supplies CT steel grades from CT55 (55,000 psi yield) through CT110 (110,000 psi yield), with CT120 also available on request. Higher grades provide greater tensile capacity for deeper wells, longer laterals, and heavier BHA strings. All tubing meets API Spec 5ST chemical and mechanical property requirements and has excellent fatigue resistance.

Q5: Can you supply Arctic‑rated coiled tubing reels for extreme cold environments?

A: Yes. SJ Petro Arctic‑rated coiled tubing reels are engineered for continuous operation at -45°C, with storage capability to -60°C. Includes low‑temperature steel for reel flanges, cold‑hardened hydraulic seals, low‑pour‑point hydraulic fluids, heated control enclosures, and water‑free pneumatics. These units are proven in Sinopec drilling campaigns in Russia.

Q6: What is the typical lead time for a coiled tubing reel or CTU order?

A: Lead time depends on capacity and customization level:

• Standard skid‑mounted CTU (24K reel): 3–4 months

• Truck‑mounted CTU (medium capacity): 6–8 months

• High‑capacity CTU (8,000 m reel): 8–10 months

• Arctic‑rated CTU: 10–12 months (includes material impact testing and certification)

Q7: Do you provide third‑party inspection for coiled tubing reels?

A: Yes. SJ Petro welcomes third‑party inspection by BV, SGS, DNV, ABS, or any certified inspection agency. We provide full access to our manufacturing facility and can arrange witnessed testing at your request. Additional fees for third‑party inspection are quoted separately.

Q8: Can your coiled tubing reel handle both in‑well operations and surface gathering line applications?

A: Yes. Coiled tubing and line pipe reels can be used for surface gathering pipelines in land oilfields and offshore platforms in addition to downhole working tubing, velocity tubing, and completion applications. Coiled line pipe is mainly used in surface gathering pipelines on land oilfields and gathering pipelines on offshore drilling platforms.
