Specialized systems used to provide reliable sealing and isolation in the annulus between tubing and casing.
Welltec® Saturn Expander
Stop unwanted gas, oil or water flow due to microannuli or local channeling in the cement behind casing.
Welltec solution benefits
Welltec annular isolation tools simplify complex downhole interventions while enhancing safety, reliability, and operational efficiency.
Combining advanced mechanical design with flexible deployment options, these tools deliver dependable annular isolation across a wide range of well conditions. By densifying cement and sealing micro-annuli, high-pressure containment is achieved with minimal impact on the wellbore’s structure, maintaining production efficiency and safety.
Prevent Gas, Oil, or Water Flow
Stop unwanted fluid flow caused by micro-annuli or local channeling behind casing.
Well Integrity Optimization
Correct unintended annular sections by locally denting the casing and densifying cement to improve long-term wellbore stability.
Sustained Pressure Management
Address sustained casing pressure (SCP) issues efficiently without requiring costly recompletion.
Flow Control
Control unwanted gas or fluid migration between multiple zones to reduce emissions and improve operational safety.
Our annular isolation tools are rigless and wireline-deployable, allowing rapid installation and repeated deployment at any target interval. The Saturn Expander’s expandable cone and hardened knuckle-bent fingers ensure precise sealing across varying annular gaps and gradients.
Patch-capable and repeatable designs allow multiple interventions in the same section, providing flexibility for future operations while minimizing downtime. Beyond sealing, these tools densify cement, protect casing, and enhance well integrity, supporting safer and more sustainable energy production.
Welltec annular isolation tools provide reliable sealing and zonal control, enabling rapid, dependable, and rigless operations while promoting sustainable well management.
