Popis: Most of the thermal recovery methods in the world have been applied to reservoirs of highly viscous crude oil with the purpose of increasing oil production by reducing its viscosity. The injection of water is generally used for the recovery of light and intermediate weight oil and continuous steamflooding for medium to heavy crude oil. During steam injection there are several mechanisms that ensure effective recovery of oil. In this article are discussed especially those related to the distillation of the lighter components of crude oil. Continuous steamflooding is technically different from waterflooding, not only for the obvious differences in the physical conditions of the fluid being injected, but also for the recovery of microscopic mechanisms involved. In fact, the main difference lies in the effect produced by condensation of water vapor, that when changing phase drags with it the most volatile components of crude generating a small front of miscibility with the original oil. When distillation of the lighter components of crude oil occurs, the main objective of the distillation process is not viscosity reduction, but the reduction of residual oil saturation at lower levels than that obtained with the injection of water. In this article a detailed description of the process is made and the experiments made at laboratory to identify the existence of this mechanism are transmitted
