High strength foamed well cement compositions and methods of cementing subterranean zones penetrated by well bores are provided. The foamed well cement compositions are basically comprised of a hydraulic cement, hydrophilic fibers, water sufficient to form a pumpable slurry, a mixture of foaming and foam stabilizing surfactants and sufficient gas to foam the slurry.

High strength foamed well cement compositions and methods

The present invention provides improved foamed well cement compositions and methods. The foamed cement compositions have improved properties and are basically comprised of hydraulic cement, amorphous silica surface treated with a mixture of organosilane coupling agents, sufficient water to form a slurry, sufficient gas to foam the slurry and a mixture of foaming and foam stabilizing surfactants present in an amount sufficient to facilitate the formation of the foam and stabilize the foamed composition.
