  • Apparatus and method for dewatering low pressure gradient gas wells
    Publication number: 20070187111
    Abstract: Disclosed is an apparatus and method for removing extraneous water from a natural gas well using a miniaturized jet pump assembly and a concentric coiled tubing string. The miniaturized jet pump assembly is attached to a concentric coiled tubing string at the surface and then run into the well as a single unit. Alternatively, the concentric coiled tubing string may be assembled in the well. Once downhole, the jet pump assembly is activated to remove extraneous water from the well thereby facilitating the production of natural gas. Should the functional portion of the jet pump assembly corrode or wear out, that portion may be uninstalled and replaced without removing the jet pump assembly and concentric coiled tubing string from the well.
