  • Patent number: 3957115
    Abstract: A method of incrementally treating a section of an earth formation around a well to improve fluid flow into the well. The method includes the steps of installing a well casing provided with spaced landing nipples, perforating and treating a bottom portion of the formation by suitable standard procedures including employing a packer in the casing above the location of perforation and treating, running a retrievable plug into the well bore, releasably locking the plug at one of the landing nipples above the first location of perforation and treating, running a perforator into the well above the plug and perforating the casing above the plug, treating the formation through the perforations above the plug, and thereafter sequentially treating the formation at selected depths up the hole by engaging the plug with a combination overshot handling tool and perforator to lift the plug upwardly and install the plug at the next landing nipple above the previously perforated and treated zone.
