CHIMERA Eco-Max™

The CHIMERA Eco-Max™ is a comprehensive wellbore clean-up tool designed to improve completion deployment efficiency in cost-driven markets. It integrates a scraper, brush, and high-capacity magnet elements onto a single completion-deployed mandrel, eliminating the need for a separate wellbore clean-up run.

The tool features a single-piece caged scraper element with 360° overlapping blades, ensuring complete casing wall coverage. The scraper's self-cleaning teeth remove cement, perforation burrs, scale, and other potentially damaging debris from the casing. Immediately behind the scraper are rows of brushes that scour corrosion pits and coupling recesses, while also acting as a barrier to prevent debris from passing below the tool and interfering with the completion.

Large bypass channels in the Eco-Max™ allow for unhindered circulation rates, facilitating debris removal. The tool can be rotated and reciprocated, although this may be limited by the completion hardware. Magnets arranged along ribs remove ferrous debris from the wellbore during cleaning, maximizing the exposure area available to trap debris while running out of hole.

The Eco-Max™ can be configured for any casing and tubing combination with matching metallurgy and connections. It is typically run below the lowest packer and made up directly to the tubing string. The tool's mandrel ID is matched to the tubing ID to prevent restrictions, and it is available with any tubing connection for direct integration into the completion string.
