GRAVITY OVERRIDE OF STEAM FRONT DISPLACING WATER IN POROUS MEDIA

 

B. PHONGDARA

ABSTRACT: The report describes laboratory results of gravity override of steam diplacing water in horizontal porous media. New formulae describing the slopes of interfaces have been derived for completel, filled and partially filled cases. For the completely filled case, the present approach, which uses a simple, one dimensionaljlow equation, shows a better time-dependence fit than the existing theory. It is identical to the existing theory at later times. For the partially filled case, the present theory shows an excellent fit to experimental results.
