Coiled Tubing Services

Field operations that circulate fluids through coiled tubing to remove sand, proppant, scale, and fill from the wellbore. Used to restore production flow paths and prepare wells for further intervention.

Coiled tubing conveyance of a mud motor and mill to drill out composite or dissolvable frac plugs after a plug-and-perf completion. Restores full bore for production and is a primary application in unconventional shale wells.

Pumping of treatment fluids, acid, gels, and nitrogen through the coiled tubing string for unloading, displacement, and gas lift kickoff. Nitrogen pumping is common for lifting fluid columns to initiate flow on depleted or low-pressure wells.

Circulating jobs that remove sand, scale, proppant, and fill from the wellbore by pumping fluid or nitrogen through the coil. Includes CT cleanout of horizontal laterals to restore flow.

Conveyance of downhole motors and mills on coiled tubing to remove scale, cement, frac plugs, and bridge plugs. Frac plug drillout in multistage completions is a primary application in unconventional plays.

Injection of nitrogen through coiled tubing to lighten the fluid column and unload a well, used to initiate or restore production after stimulation or workover.

Retrieval of stuck tools, debris, or parted strings using coiled-tubing-conveyed fishing assemblies. Performed under pressure to avoid killing the well and minimize formation damage.

Spotting and circulating acid or other treating fluids through coiled tubing to dissolve scale or near-wellbore damage and improve injectivity, often with precise depth placement along the interval.

Running fishing tools or mills on a bottom hole assembly to recover lost equipment, cut obstructions, or mill packers and bridge plugs within the casing.

Use of coiled tubing to push logging, perforating, or stimulation tools into highly deviated and horizontal wells where gravity-deployed wireline cannot reach total depth. Enables real-time measurement when fitted with an internal conductor line.

Coiled tubing with an internal electrical cable that enables real-time downhole measurement, depth correlation, and powered tools such as logging and perforating during intervention.

Cold-weather and logistically isolated coiled tubing operations, including North Slope and northern Alberta locations. Requires winterized equipment, heated enclosures, and self-contained crew support for sustained operation in extreme conditions.

Provision and operation of the surface pressure-control stack, including stripper, blowout preventer, and injector head, that allows intervention on live wells. Ensures barrier integrity throughout deployment per API RP 16ST.

Heavy-duty CT strings and units rated for greater depths and longer horizontal reach, used to access deep wells and extended laterals where conventional CT cannot reach total depth.

Use of coiled tubing to convey or isolate during fracturing and to set or activate completion components, enabling staged stimulation without a separate workover rig.
