Title: Method and apparatus for stimulating oil well production

Patent ·
OSTI ID:6105854

A system for cleaning perforations in a well bore where the perforations are located below a packer means on a production tubing. A tool on a string of pipe has packer means for sealing off the cross-section of the production tubing and the pressure in the annulus between the string of pipe and production tubing is reduced. The tool has a bypass passage across the packer means which opens upon the reaching of a predetermined pressure across the packer means and the high volume pressure from the earth formations suddenly flows through the tool and cleaning of the perforations is effected.
