The OSI CHEM SCREEN is a more effective alternative to traditional downhole chemical treating.  Through micro-encapsulation technology all the active components of the most effective liquid chemical treatments, in the petroleum industry are processed in a solid stick form.

The solid chemical stick is placed in a tool that is installed below the pump intake.  When the CHEM SCREEN is installed downhole, activation and dispersion of the chemicals occurs more quickly, more effectively and with greater consistency.


- Reduces paraffin, scale and corrosion failures.

- Treats from the bottom up.
- Refillable tool design.
- Slow, self-release.

- Chemical treatment below the packer.
