ABSTRACT:
A method and apparatus for determining the vapor flow only, or the vapor and liquid flows into various formations surrounding a thermal injection well. The apparatus utilizes a downhole tool having bristles on its outer surface for impeding the flow of fluid past the tool and an instrument at the surface for measuring the drag force produced on the tool as it is moved downward and upward through the well. The fluid flows at various depths in the well are calculated from the measured drag forces.
