Downhole surge tools
Patent
·
OSTI ID:5778678
Downhole surge tools are claimed for efficient well completions wherein natural earth energy is utilized by the exploitation of a maximum pressure differential into a given well bore. The tools of the apparatus function to back surge the well, enhancing reservoir communication, saving time and reducing costs. Tools of the apparatus include a tubular nipple, a surge plug inserted operationally into the nipple, and an optional catcher sub connected thereto. The entire tool assembly is production actuated by dropping a recoverable bar of sufficient weight to overcome that buoyant force which seals the plug within the nipple. The essence of invention resides in the economy of time and material.
