Downhole surge tools, method and apparatus
For use with a well having a bore, a casing, and production perforations, a method of well completion comprising the steps of: (A) installing, on the downhole end of production tubing, below a production packer, a tubular nipple, said nipple having an ejectable non-frangible surge plug sealably disposed in the lower end thereof; (B) lowering the assembly of step (A) into the well bore, positioning said surge plug above the perforations; (C) positioning and setting the packer above said assembly; (D) drop bar ejecting said surge plug to provide a substantially instantaneous full opening at the bottom of the tubing, whereby a maximum pressure differential into the well bore is substantially instantaneously created, whereby fluid and particulate matter from the well bore and formation surge inwardly and upwardly through the tubing.
