Non-aqueous foam composition for gas lift injection and methods for making and using same

A method comprising the steps of:

• pre-mixing a retention composition with a gasifying amount of a gasifying gas to form a gasified retention composition, where the gas retention composition comprises a hydrocarbon base fluid and viscosifying agent comprising a polymer, or a cross-linkable composition including a gelling agent and a cross-linking agent or mixtures or combinations thereof and where the gasified gas retention composition transitions from a liquid to a foam upon a change in pressure with or without a corresponding change in shear, and
• injecting an effective amount of a gas lift composition into well fluids in a producing oil and/or gas well or an oil and/or gas well being brought on production, where the effective amount is sufficient to reduce a density of the well fluids to a desired value below a value of the well fluids in the absence of the gas lift composition and increase well fluids production, where the gas lift composition includes a lift gas and the gasified retention composition, and where the gasifying gas and the lift gas are the same or different.

The method of claim 27, wherein the inert gas is selected from the group consisting of helium, neon, argon, xenon, krypton, or mixture or combinations thereof.
