Overview
The PETROCO Swellable Packer is a high-performance zonal-isolation system that uses advanced self-healing elastomers. When exposed to wellbore fluids such as hydrocarbons, water, or gas, the elastomer gradually swells and expands to seal the annulus. This provides a simple, safe, and reliable barrier without the need for mechanical setting tools.

Applications
    •    Open-hole or cased-hole zonal isolation
    •    Production-tubing packer backup and liner-hanger backup
    •    Cement-assurance operations
    •    Stimulation placement and selective acidizing
    •    Intelligent well and smart-completion systems
    •    Water-shutoff, gas-shutoff, and sand-control support
    •    Multi-zone completions, compartmentalization, and open-hole straddle designs
    •    Integrity repair and inflow control in damaged or irregular wellbores

Features & Benefits
    •    Self-healing elastomer: Automatically swells upon exposure to target wellbore fluids to create a long-lasting, robust seal.
    •    High-pressure performance: Bonded-to-pipe design allows rotation and reciprocation during run-in while supporting differential pressures  up to 15,000 psi.
    •    Customizable sizing: Element length and OD can be tailored to match specific well designs and completion requirements.
    •    Slip-On option: A quick-install version ideal for wells where a bonded swellable packer is not practical; offers high flexibility and reliable  sealing even in challenging conditions.
    •    No special tools required: Can be installed easily by rig personnel without specialized running equipment or expert crews.
    •    Ideal for irregular geometry: Provides an effective isolation solution in wells with irregular borehole shapes and can replace or  complement cementing and perforation in certain applications.
    •    Long-term integrity: Maintains annular sealing over extended periods, even under harsh downhole environments​​​​​​​

​Slip-on Swellable Packer
Slip-on is a pre-assembled high-performance swellable packer especially designed for high differential pressure applications where a bonded swell packer (old type of swell packer) is not viable for logistic reasons.
It easily slips on pipe and provides on-site installation in a very short time.
Its reduced overall length allows for increased installation flexibility throughout the well trajectory and optimal
zonal isolation.
The slip-on innovative sealing concept allows for stacking multiple units in series for increased differential pressure holding capability up to 15,000 psi. slip-on swells in all well fluids containing aqueous and
hydrocarbon fluids, especially swells in wet and dry gas.​​​​​​​

​PETROCO is the only company that has obtaining the functional test approval according to the API 19OH (Zero Bubble) standard from the NISOC.
