Abstract
A method and apparatus for measuring both the quality and flow rate of steam injected into a hydrocarbon formation in a thermal recovery process. The method measures both the quantity of water and the flow rate of the steam. Both measurements can be made at any location in the borehole to determine the quality and quantity of steam injected into a particular formation. The apparatus utilizes a propeller motor/generator combination to determine the vapor flow rate; the drag produced by a network of bristles extending across the borehole determines the vapor flow rate and the quantity of liquid present.
