The purpose of this study was to report on the effectiveness of the Hyperscratcher tool in improving production or injection by cleaning out boreholes that have reported problems with scale, paraffin, or asphaltene build-up.

The Hyperscratcher tool was initially designed and used in California in the 1980s for workovers; as yet it has not been widely used in Wyoming.

Test results show use of the Hyperscratcher Tool significantly improved production in 7 of the 8 wells tested with production improvement varying from 20% to 120%.
