The present invention relates to air drilling and an apparatus, system and process for air storage for speeding up and making the air drilling process in a wellbore more efficient. The present air storage system is used to divert high pressurized air from the air compressors into an air storage tank for storage during drilling process of adding another piece of pipe to the well. In the present invention, the compressed air can be stored in the air storage system until the connection is made and the driller is ready to resume drilling. This high pressurized, large volume of stored air in the air storage system helps the compressors quickly build up enough air to resume the drilling process thus reducing the amount of drill downtime during the process of making a new pipe connection in a well.
