Scraper Tool

Downhole scale & debris removal tool

Download Spec Sheet

The Oilenco scraper tool is a fully adjustable downhole scale and debris removal tool that can be set to any specific diameter and precisely adjusted to suit downhole conditions.

The scraper tool has a unique ‘anti-jamming’ feature that allows the cutting teeth to ‘relax’ during upward motion.

The tools are nominally sized to suit standard tubing sizes and are supplied with a set of cutting teeth to cover the entire tubing range plus any common restrictions.

The tool offers an effective and efficient method of scale removal, effortlessly removing small amounts of material with each pass. Not only is this method more efficient, it also prolongs the sharpness of the cutting teeth.

PRODUCT FEATURES

  • Anti-jamming feature
  • Size adjustable
  • 360° scraper coverage
  • Sampling cup can be attached to capture samples of scale

HOW IT WORKS

The scraper tool should be set to a diameter marginally bigger than the last known drift diameter. The tool is then run into the well and worked through any tight spots in the affected tubing area.

Once clear, the tool is returned to the surface, and the diameter slightly increased by rotating the adjustment ring. The tool is redeployed and again worked through any tight spots in the tubing. This process is repeated until the scale has been completely removed.
