ABSTRACT:
A method of improving the quality of liquid coming from a well that has a pump and pipe assembly. The method includes identifying a region of the well that is low in contamination and a region of the well that is high in contamination, and modifying the pump and pipe assembly so that suction of the assembly is enhanced in the region that is low in contamination and inhibited in the region that is high in contamination. The method also includes cleaning the well in the region of low contamination. Modifying the pump and pipe assembly includes coupling a suction control device to the pump and pipe assembly, and positioning the suction control device in the region of low contamination, and forming a barrier between the region of low contamination and the region of high contamination by attaching a flow control disk to the pump and pipe assembly.
