Coiled Tubing Tools and Bottomhole Assemblies
Advanced coiled tubing tools are necessary for implementing coiled tubing technologies. The CoilTOOLS portfolio of coiled tubing tools for standard bottomhole assemblies includes motor heads, connector checks, valve-disconnect assemblies, knuckle joints, fixed and hydraulic centralizers, fixed and rotary wash tools, nipple locators, gauge carriers, and a complete suite of downhole valves.
PowerCLEAN Wellbore Fill Removal
Improve Safety and Reduce Stuck-in-Hole Incidents with Efficient Cleaning
PowerCLEAN engineered fill removal service cleans previously uncleanable tools at up to 325 degF. The service integrates an optimized jetting nozzle and cleanout fluids with job-planning software and real-time monitoring.
This coiled tubing service can remove produced sand and fines, proppant left behind after fracturing, or excess gravel from gravel-packing operations efficiently and completely. Our service leaves the tools fully open for maximum hydrocarbon production and problem-free tool runs.
Clean deviated and horizontal sections
Significant amounts of fill are often left in highly deviated or horizontal tools sections when you use conventional cleanout nozzles. PowerCLEAN nozzle technology agitates the solids, entrains them in the cleanout fluid, and prevents particles from falling back past the nozzle.
The result is quick and complete solids removal at lower flow rates than conventional nozzles allow. With the PowerCLEAN service, effective cleaning is possible at flow rates as low as 1 bbl/min for 7-in casing and 2 bbl/min for 9 5/8-in casing at any deviation angle.
Increase simulation accuracy
User-friendly PowerCLEAN software lets you optimize equipment, fluids, and job procedures. The optimized job design cuts costs by shortening cleanout time and reducing the fluid volume to be pumped.
CoilFLATE Through-Tubing Inflatable Packer
Reliable Zonal Isolation
Designed for extreme conditions, the CoilFLATE coiled tubing (CT) through-tubing inflatable anchoring packer extends critical zonal isolation capability to previously inaccessible, chemically harsh, and high-temperature environments. The CoilFLATE packer eliminates the need for a workover rig because the packer is run on either coiled tubing or jointed pipe into vertical, deviated or horizontal tools. Remedial operations can be performed without killing the well.
Applications
By deploying the CoilFLATE packer, you can permanently abandon zones or temporarily isolate tools areas for tubing integrity testing, wellhead testing, and general pressure testing in openhole and cased hole wells. The packer's resistance against aggressive chemicals lets you selectively place treatment fluids for acid stimulation, water control, and chemical treatment.
Safety
The CoilFLATE design keeps the packer anchored in place, providing a reliable high-pressure seal at large inflation ratios (2:1 at 5,000 psi, 3:1 at 2,000 psi). It also allows extended assembly exposure at temperatures up to 375 degF under harsh tools conditions and in almost any chemical environment.
Accurate depth control
The CoilFLATE high-pressure, high-temperature (HPHT) system ensures absolute depth control via casing collar log correlation for optimum packer positioning.
Vantage Coiled Tubing Logging Head System
Designed to standardize electric-line coiled tubing (CT) connectivity, the Vantage CT logging head saves you rig-up time through reliability, modular interchangeability, and the unique design of the bayonet CT connector.
Vantage can be used for mono-conductor logging applications as well as with most perforating configurations. The system's modular component concept connects with plug-and-play connections that physically and electrically couple the components. These connections enable rapid interchangeability and reduce nonproductive time. The use of the CT flush OD bayonet connector in combination with the Vantage termination tool enables pretermination of the electrical connection before the CT is stabbed through the injector head chains. Highly reliable, the Vantage system can perform multiple runs in hole without redressing.
The Vantage system is designed for offshore, land, desert, and arctic environments and for oil, gas, and injector wells. It is rated for working pressure of 13,500 psi, maximum temperature of 375 degF, and maximum tensile strength of 40,000 lbm.
Packers, Hangers, Plugs, and Accessories
Packers and plugs are run to hydraulically isolate the sections above and below the packer and to provide a mechanical anchor to prevent the packer from sliding inside the wellbore. In coiled tubing (CT) completion applications, the packer also holds the CT string in place.
Packers are set mechanically, hydraulically, or on wireline. The mechanical-set packer is set by applying either tension or compression on the packer. The hydraulic-set packer is activated by hydraulic pressure. The CoilTOOLS hydraulic set-packers can also be set on wireline.
The CoilTOOLS suite of packers includes the entire range of packers and plugs used in wellbore treatments, selective stimulation, water conformance jobs, tubing integrity testing, CT completions, straddle repair installations, temporary or permanent well abandonment, and more.
Whenever packers or plugs are run, the downhole hydraulic and mechanical situation must be known. The shear pin setting must be high enough to withstand the additional forces resulting from applied differential pressure, yet low enough to allow a safe release of the packer. An equalizing tool or unloader valve may be needed to safely unset the packers.
Discovery MLT Multilateral Reentry System
Controlled, selective entry on coiled tubing for multilateral wells
Discovery MLT multilateral reentry system is cost-effective and operationally simple for maximizing performance of multilateral wells. The system sends a pressure signal to the surface confirming you've accessed the correct lateral.
Adjusting the suborientation, or bend, from surface and the real-time feedback to surface of window identification save a substantial amount of time. This significantly increases the chance of successful reentry on the first attempt. Only one run to the bottom of the lateral is required for confirmation.
Discovery MLT software
Using Discovery MLT software, you can display several essential parameters, such as the tool orientation relative to the lateral window. The application also monitors previous indexes and guides you through indexing cycles for accurate, real-time information downhole.
After the window is profiled, the software memorizes the window orientation and monitors the BHA orientation, facilitating the location of other windows.
You can determine job feasibility with our CoilCADE CT design and evaluation software and monitor and record real-time data with CoilCAT acquisition software.
Compared with accepted techniques using full-scale rigs and benchmark drill pipe, Coiled-Tubing Drilling (CTD) can significantly decrease environmental influence. CTD is mostly a reentry drilling service that enables operators to more competently find hydrocarbon pouches still untapped in the reservoir. Reentry wells reduce the locality at the exterior impacted by drilling, but also reduce the volumes of iron alloy, cement, and drill cuttings conceived in the drilling method with Hydraulic Well Fracturing Process. Coiled-tubing technologies replace the customary rigid, jointed drill pipe with a long, flexible coiled pipe string. This can reduce the cost of drilling, as well as supply a smaller environmental footprint. In particular, less drilling grime is needed, which decreases the use of nonrenewable assets and minimizes the promise for unplanned issues. Coiled tubing furthermore uses slimhole drilling techniques to accomplish very cost-effective drilling and less impact on the natural environment. In supplement, because drilling procedures are not cut off for pipe connections, CTD can use shut" mud circulation methods, which decrease the risk of spills and blowouts.
