Abstract

Two methods and two steam samplers are disclosed for sampling steam, as at the bottom of a steam injection well for determining the quality of the saturated steam just prior to penetrating the formation. The samplers each comprises an elongated cylindrical vessel with a tube having openings extending longitudinally internally of the vessel for forming an annulus between the vessel and the tube for trapping steam liquid phase while ejecting the steam vapor phase. The tube has a second internally sliding tube for closing the openings and a latch for releasably locking the tubes in closed position for sealing the steam liquid phase in the annulus for recovery at the surface. A method for sampling and a method for forming a sampler, as well as two latch combinations are disclosed.
