Advanced Coiled Tubing Tools

Enhance wellbore conductivity and optimize production

Drive production with advanced tools and increase your coiled tubing capabilities

For more than 25 years, operators have turned to the engineers and scientists at Baker Hughes to solve major production problems with innovative coiled tubing (CT) technologies. The Baker Hughes CT services team has pioneered a number of specialized applications and proprietary tools for CT such as:

  • Closed-loop cleanout systems
  • Industry-leading scale removal techniques and tools
  • Sand cleanout services that extend to laterals in deviated wells
  • Targeted acid placement
  • First truly effective means for re-entering multilateral wells

Most applications are aimed at increasing production, whether by removing sand, scale deposits and debris from the wellbore, or by stimulating the formation by acidizing. Baker Hughes leverages technical expertise to anticipate industry needs, often developing solutions for specific customer requirements.

For ultralow reservoir pressure wells, our Sand-Vac™ and Well-Vac™ systems provide specialized options for removing solids and retrieving fluids.

The Baker Hughes Sand-Vac and Well-Vac systems use concentric CT (CCT) combined with a proprietary downhole switchable jet pump to remove solids and liquids from ultra-low-pressure wellbores that are not treatable with standard circulating methods. These cleanout systems isolate the fluids from the reservoir and allow continuous returns without the use of nitrogen. This is particularly advantageous for cleanout operations that require significant amounts of nitrogen or have issues related to supply, logistics, or platform deck space.

Used in extended-length producing intervals, these systems handle crossflow or thief-zone challenges that hamper conventional circulation cleanouts. The tools also incorporate optional built-in pressure and temperature memory gauges to collect accurate downhole data.

The Baker Hughes Roto-Jet™ rotary jetting system is a highly effective alternative to conventional milling to disintegrate and remove scale in a single run.

The Baker Hughes Roto-Jet jetting tool economically removes downhole deposits that can impede well productivity. This unique, rotary jetting technology introduces destructive stress cycling to the deposit by accurately controlling the rotational speed of the jetting nozzle.

With each pass of the jet stream, surface cracks are briefly pressurized to induce local tensile stress in the scale. This stress cycling occurs several times each second and causes brittle scale to shatter into small particles that are easily transported to surface.

The result is single-pass cleaning from surface to total depth. Even the hardest scales, such as silicates and barium sulfate composites, can be removed with Roto-Jet technology.

The patented Baker Hughes Tornado™ well cleanout process cleans sand beds from deviated and horizontal wells at efficiencies approaching 100%.

The Tornado CT cleanout system is the most powerful, flexible, and effective CT wellbore cleanout method available. It is ideal for removing a variety of solids from any wellbore geometry and trajectory. The patented system allows flexibility in running accompanying bottomhole assemblies such as standard wash nozzles, motors, mills, and rotary jetting tools. You get an optimized cleanout, even with compacted or loosely consolidated fill such as formation fines, pebbles, and proppants.

A suite of proprietary, custom-designed downhole tools complement field-proven operating methods to maximize the Tornado system’s capabilities. These tools provide full forward-facing washing capability while penetrating fill material, and can be switched to high-rate uphole sweeping during the engineered wiper-trip procedure.

Our patented StimTunnel™ targeted acid placement service increases the reservoir drainage area, leading to improved production in carbonate reservoirs.

The StimTunnel™ targeted acid placement service stimulates selected zones in carbonate reservoirs by creating large, connecting tunnels from an openhole main bore. This targeted stimulation method delivers improved, longer-lasting production gains with fewer production impairments.

The combined effect of high-pressure jetting and chemical rock dissolution in acid generates a drilling effect that enables the StimTunnel tool to construct secondary tunnels away from the main bore. New tunnel trajectory and orientation can be downloaded from an optional memory inclinometer gauge incorporated in the tool string.

The Baker Hughes Lateral-Entry Guidance (LEGS™) system allows reliable selective reentry in multilateral wells for conventional CT stimulation and cleanout treatments.

The LEGS system easily and reliably locates and enters all branches of a multilateral well to remove fill or stimulate the entire well in a single run. A specially designed rotating wand searches for junctions in a 360° sweeping motion and then enters any series of multilateral branches.

The system notifies the operator of its progress with a simple pressure signal that indicates when a lateral junction has been successfully located and the coiled tubing progresses into the well.

Unlike other types of multilateral entry devices, this system uses a proprietary methodology that does not require complex electrical controls or steering systems, and it is more effective than simplistic bent subs runs on indexing tools.

DuraLink™ spoolable coiled tubing connector

The DuraLink spoolable connector enables longer, larger diameter coiled tubing to be mobilized where previously limited by crane or road capacities. It provides a highly reliable tube-to-tube connection that is superior to butt-welded connections.


Sand-Vac and Well-Vac Cleanout Systems

Sand-Vac and Well-Vac cleanout systems provide options for removing solids and retrieving fluids in ultralow-reservoir-pressure wells.

EasyReach Extended-Reach Coiled Tubing Service

The EasyReach™ extended-reach coiled tubing service delivers an optimal solution for servicing long horizontal wells—offering predictable, repeatable, and reliable performance in extended laterals.
