  • Patent number: 5291947
    Abstract: A tubing conveyed straddle packer system includes two inflatable packers interconnected with each other and spaced apart to provide for isolating a wellbore space for communicating pressure fluids between a formation zone of interest and the surface through the tubing string. An electrical cable extends within the tubing string and is operable to provide control signals to electrically controlled valves for inflation and deflation of the packers and for conveying fluids between the formation zone of interest and the tubing string and between the tubing string and the wellbore above and below the straddle packer system. A logging tool is interposed in the tubing string for precisely locating the straddle packer system in the well.
