  • Method for determining a steam dryness factor
    Patent number: 8645069
    Abstract: A simple, applicable in the field, and extra-equipment free method is provided for determining steam dryness directly in a thermal recovery of high-viscosity oil. A non-condensable gas is added into a saturated steam being injected into a well. The presence of non-condensable gas changes partial steam pressure. Correspondingly the steam condensation temperature also changes. The borehole temperature or pressure measurements can be used to evaluate the steam dryness.

  • METHOD FOR DETERMINING A STEAM DRYNESS FACTOR
    Publication number: 20090248306
    Abstract: The present invention provides an easy, field applicable, and extra-equipment method for determining steam dryness directly under thermal high-viscosity oil stimulation. The technical effect is achieved by adding the gas non-condensed in a well under flooding to the saturated steam pumpdown. The non-condensed gas occurrence of the mixture will vary partial steam pressure. In doing so, the steam condensation temperature will vary too. The borehole temperature or pressure measurements can be used to evaluate the steam dryness.
