  • Well development tool and method for use thereof
    Patent number: 6868904
    Abstract: A well development tool quickly develops a well created for underground water testing using a hollow tubular member that has a check valve on an end and a washer that has a diameter that is at least equal to the inside diameter of a well casing within the well. The well development tool is reciprocated up and down so that the washer pushes and pulls on the underground water and the tool captures the water that is originally at the well casing site and allows outlying water to percolate to the well casing.
