    "A production logging technique that uses a tool with an inflatable packer or diverter to temporarily block the annulus and force all wellbore fluid to pass through a central measurement section. This action increases the fluid velocity and improves the response of sensors like spinners, especially in low-flow-rate wells or large-diameter casings where fluid movement is slow. The tool's measurements are then corrected for the reduced flow area to reflect actual downhole conditions.",
    "Describing a production logging tool design that channels wellbore fluids through a smaller, restricted path where sensors are located. This method increases the local fluid velocity and improves the response of sensors like spinners, especially in low-flow-rate wells or large-diameter casings. The tool's measurements must then be corrected for the concentrating effect to reflect the actual flow rate across the full wellbore diameter."
