Product Description

A scraper is a specialized downhole tool designed to remove unwanted deposits, such as paraffin, wax, scale, and other solids, that can accumulate inside wellbores and pipelines. These deposits can significantly impede the flow of oil and gas, leading to reduced production and increased operational costs.

Types of Scrapers:
Scrapers come in various forms, each tailored to specific applications and deposit types. Common types include:
1.Mechanical Scrapers: These scrapers utilize a mechanical action, often a series of blades or brushes, to physically scrape away the deposits. They are often used for removing heavier, harder deposits.
2.Hydraulic Scrapers: These scrapers rely on the pressure of the drilling fluid to dislodge the deposits. They are typically more suited for softer deposits and are often used in conjunction with other downhole tools.

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.

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.
