Hyperscatcher
Hyperscatcher- The Hyper Scratcher System is a multi-phase cleaning system that gives oil companies a cost-effective means of well stimulation by cleaning the immediate interface between producing zone and invaded zone without forcing fluid into formation and altering its permeability. It is designed to be applied in three main types of wells: liner completed wells, inner liner completed wells, and solid string completed wells.
The tool itself consists of four major components: the jet alignment, brush configuration, filtering system, and the main body structure. No wash cups are involved in the operation of the tool, which means that fluid is not forced into the formation. The top and bottom collars of the tool act as centralizers and allow the washing fluid to be evenly displaced
The Hyperscratcher is a proven technology which has a 100% successful track record at significantly increasing oil and gas production in over a 145 wells.
The average increases are:
250% on oil wells
90% on gas wells
66% on disposal well efficiency
