ABSTRACT:
An apparatus and method are disclosed for determining the steam quality of a steam-water mixture prior to passage of the mixture from a steam injection well into steam-floodable formations located adjacent the well. The apparatus which may be lowered down into a steam injection well comprises a radiation emitting source located a selected distance away from a radiation detecting source. The steam-water mixture passes between the emitter and the detector. In operation an increase in the water content of the mixture causes attenuation of the radiation received by the detector. The decrease in the radiation received by the detector decreases the output signal of the detector. Corresponding signal changes as the steam quality of the mixture varies may be studied to determine the existing downhole steam quality at a particular location in the well.
