摘要： Embodiments of the present disclosure generally relate to apparatus and methods for foam generation, and to apparatus and methods for evaluation of foam systems. In an embodiment, a method of analyzing foam properties includes delivering a foaming composition and a gas to a housing at a pressure of 500 psi to 6,000 psi and a temperature of 35° C. to 150° C., the housing containing an unconsolidated porous media. The method further includes flowing the foaming composition and the gas through the housing, and forming a foam by an interaction of the foaming composition, the gas, and the unconsolidated porous media. The method further includes directing the foam from the housing to a visualization chamber, the visualization chamber in fluid communication with the housing, and measuring a foam characteristic via the visualization chamber. The characteristic may include foam half-life, pressure drop through the unconsolidated media, and/or apparent viscosity of the foam.

摘要： Methods and materials for foam production in enhanced oil recovery operations are described herein. More specifically, embodiments of the present disclosure relate to foaming agents, gas mobility control agents for use in porous media, compositions comprising such agents, methods for using such agents, methods for generating foams, and systems for enhanced oil recovery. In an embodiment, a method for recovery of oil from a porous rock formation is provided. The method includes contacting a foaming fluid and a surfactant solution described herein with the porous rock formation, and generating a foam comprising the foaming fluid and the surfactant solution. The method further includes mobilizing oil from the porous rock formation by contacting the porous rock formation with the foam; and collecting at least a portion of the mobilized oil.
