WebBasic screening criteria for foam application for gas mobility improvement or GOR control are as following: • Lithology: surfactant (foamer) selection considers, surfactant adsorption rock surface (low surfactant adsorption is more favorable). • Webrequirements on foam plastics: a Flame Spread Index of less than 25 and a Smoke Developed Index of less than 450. This requirement must be met regardless of meeting other fire test requirements. A foam plastic which meets the more stringent 25/450 requirement is sometimes referred to as a “Class A” foam insulation.
