Abstract
A method and an apparatus are disclosed for the measurement of the aridity, temperature, flow rate, total pressure, still pressure, and kinetic pressure of steam at a downhole location within a well through which wet steam is flowing. The apparatus comprises a series of fiber optic sensors that are mounted on sections of a shell assembly. The apparatus is lowered into a well to different downhole locations, and measures the multiple parameters of steam at different locations and heights. The data can be stored on board for subsequent analysis at the surface when the apparatus is retrieved from the well. The apparatus is very reliable, accurate, and of long-life in harsh environments.
