The present invention is directed to an aerosol foam composition comprising roflumilast, an emulsifier blend containing cetearyl alcohol, dicetyl phosphate, and ceteareth-10 phosphate and a hydrocarbon propellant. The aerosol foam composition is preferably an oil in water emulsion. The propellant is a mixture of liquefied hydrocarbon gases preferably a propane / isobutane / butane blend. The hydrocarbon propellant results in an aerosol foam which is stable, has consistent physical properties, excellent aesthetics, and no discernable degradation after long term or accelerated storage conditions.

This invention relates to the field of carbon storage and utilization technology, specifically disclosing a method for increasing carbon dioxide storage capacity using an aerosolized foaming agent. The invention employs an aerosolized foaming agent, which not only utilizes formation water for in-situ foaming to increase carbon storage space but also achieves dynamic stability after foam collapse. In-situ foaming is achieved around the wellbore through alternating injection of a pre-placed aerosolized foaming agent slug and a post-placed CO2 slug. By setting a real-time injection pressure feedback mechanism to dynamically adjust the injection method, early carbon dioxide breakthrough and loss are reduced, significantly improving storage efficiency and effectively enhancing the carbon dioxide storage effect.
