This paper presents the results of laboratory flow experiments concerning the revaporization recovery of retrograde condensate by dry gas injection. The purposes of the work were to demonstrate that the flowing fluid is vapor in equilibrium with the condensate, to investigate the effect of wettability on the revaporization of retrograde liquid, and to provide an indication of the amount of dry gas necessary to recover the heavy components from a sour condensate fluid. Four flow tests were performed in 10.6 ft-long sand packs at 100$F and 1,500 psi. Comparison of the effluent fluid analyses from all test runs with known equilibrium data shows that the flowing fluid was equilibrium vapor and that the mixing zone between equilibrium vapor and dry injection gas was short. The data indicate that complete recovery of retrograde liquid is possible if it is contacted by a sufficient quantity of dry gas. The amount required depends on reservoir temperature and pressure and also on the composition of the condensate. (14 refs.)
