ABSTRACT:
Apparatus and methods for simulation of steam flooding oil recovery operations are disclosed. The steam flooding apparatus comprises an elongated chamber to which sand is supplied. The mass, permeability and porosity of the sand is measured. The sand is then flushed and is filled with oil to the degree desired. A steam generator, which is designed so as to eliminate diphasic steam/water conditions while permitting accurate measurement of the quality of the steam and of the mass injected, supplies steam to the chamber. The quality of the steam is carefully recorded, and the pressure within the chamber and the temperature is recorded as a function of time. Steam overflood conditions and the effect of various coinjectants can also be evaluated using the apparatus and techniques according to the invention.
