What is Micro CT?
The Baker Hughes Micro CT Service leverages a modular, lightweight design and smaller footprint to provide an effective, efficient alternative to conventional coiled tubing (CT) units for offshore applications — especially on platforms where available deck space is at a premium or crane capacity is limited.
How it works.
The Micro CT service package incorporates specifically designed modular Baker Hughes CT equipment that meets DNV Lifting standards, Zone II specifications, Class 1 Division II specifications in Gulf of Mexico, and API Pressure Control standards.
Baker Hughes engineers have redesigned a standard CT unit into smaller and lighter modules. The unit breaks down into small components that are easily and quickly rigged up to reduce downtime and increase efficiency. The unit runs 5/8-in., 3/4-in., and 1-in. work strings with a 17,000-lbf pull injector head capacity. It can also be customized to run larger coiled tubing, injector heads, and reels if necessary.
Don’t compromise.
The Micro CT service provides a safe, more cost-effective solution to service even marginal wells, both offshore and onshore. It eliminates the need for self-erecting cranes and larger support/supply vessels costs. And the Micro CT components are easy to transport and rig up because of its lightweight, modular construction, thus also reducing logistics and support personnel requirements.
Add in industry-leading, proprietary CIRCA modeling software that will engineer confidence into your CT operation and well-trained, experienced Baker Hughes crews, the Micro CT service enables conventional CT work to be accomplished utilizing a smaller CT size and optimizing the operations while minimizing risk, with flawless execution.
Choose the Baker Hughes Micro CT service and get all of the efficiency of a traditional coiled tubing application without compromise… or unnecessary costs.
Micro CT Coiled Tubing Service
Reduce expenses by minimizing NPT and boosting workover efficiency
The Baker Hughes Micro CT service incorporates all the benefits and capabilities of a conventional offshore coiled tubing (CT) unit, in a compact, lightweight, small-footprint system. This new service permits offshore interventions on wells where it was previously economically unfeasible due to low production, the lack of available workover vessels, and/or deck-space/lifting-capacity limitations. The Micro CT service provides operators with a ?exible, cost-effective intervention solution for offshore wells.
By eliminating the need for an onsite support vessel to deploy coiled tubing, the Micro CT service offers significantly more service opportunities for wells that are either shut in or awaiting service. This allows operators to transform idle assets into cash-?ow contributors quickly and efficiently.
Applications
Offshore and onshore locations with lifting, space, or weight limitations, and restricted access
– Perforating, stimulation, cementing, and gas lifting
– Milling and cleanout operations
– Logging operations
– Mechanical intervention
Cleanouts
Stimulation treatments
Fluid lifts with nitrogen
Fishing operations
Scale removal
Hydrate removal
Asphaltene removal
Other remedial and intervention procedures
The Micro CT equipment can be deployed at any offshore wellsite without the additional logistical challenges typically experienced with CT operations supported by supply vessels and barges. The intervention and remediation work can be performed as often as required without the operator having to depend on the availability of expensive workover barges, rigs, or self-erecting cranes. This will save on both nonproductive time (NPT) and workover time, resulting in significant cost savings for the operator. Similarly, the Micro CT unit can be deployed in land locations where available roads might limit a conventional coiled tubing unit’s ability to gain access in a safe manner.
Proprietary Baker Hughes friction reducers significantly improve the pumping capabilities of smaller strings by minimizing the ?uid friction in restrictions through the ?ow path down hole. As part of the inherent Baker Hughes pre-job analysis, proprietary CIRCA modeling software accurately predicts solid removal scenarios for cleanout purposes, and also provides a detailed mechanical stress analysis to visualize the string performance in the well.
