...K. K. Mohanty; W. H. Masino, Jr.; T. D. Ma; L. J. Nash Summary The objective of this work is to identify the role of three-hydrocarbon-phase flow in the displacement of a reservoir oil by light-hydrocarbon-gas mixtures (methane through n -butane). Slim-tube displacements were conducted with several...

...-injection project often involves blending liquefied petroleum gas (LPG) with dry gas (mainly methane) to obtain the desired injectant composition. A common practice in the industry is to use an injectant composition at or above the minimum miscibility enrichment (MME) and maintain a pressure at or above...

...D. M. Boersma; Jacques Hagoort Summary This paper presents a comparative study, based on analysis of phase behavior, compositional reservoir simulations, and slim-tube experiments, of displacement characteristics of nitrogen and methane flooding into a volatile-oil reservoir. Results show...

This limitation of the PREOS results from an improper procedure of determining coefficients a, b , and α for the plus fraction and for hydrocarbon components with critical temperatures less than the system temperature (i.e., methane and nitrogen). This paper presents a practical approach to calculating...
