Modeling Foamy Oil Flow in Porous Media
Certain heavy oils which foam under severe depressurization give rise to increased recovery factor and an increased rate of production under solution gas drive. These oils not only stabilize foam, but also stabilize dispersion of gas bubbles at lower volume ratios. The way this phenomenon is related to the chemistry of the oil and its viscosity is presently not understood. We present here a mat...

Certain heavy oils which foam under severe depressurization give rise to increased production and an increased rate of production under solution gas drive. The phenomenon seems to be related to the chemistry of these oils which not only stabilize foam but also stabilize dispersion of gas bubbles at lower volume ratios. We present here a mathematical model of this phenomenon which depends only o...
متن کاملA Mixture Model for Foamy Oil Flow in Porous Media
The processes of nucleation, bubble growth and finally the creation of connected gas during the pressure draw-down in an oil reservoir are discussed. From these mechanisms, possible descriptions of foamy oil production appear. One of these mechanisms is the creation of bubbles, small compared to pore sizes, which move with the oil phase and which push the oil out of the reservoir. If this mecha...
متن کاملFoamy oil ow in porous media
This model is motivated by the need to explain anomalous features associated with production from reservoirs of so-called foamy oils. These oils are described by some of their properties of response to pressure declines; it is noted that they nucleate dispersed gas bubbles and display obvious foaminess in well head samples produced by solution gas drive in which oil and gas is produced by the d...
