Injection wells used for injection of hydrocarbons which are of pipeline quality and are gases at standard temperature and pressure for the purpose of storage. 4. Any dug hole, drilled hole, bored shaft, improved sinkhole, or subsurface fluid distribution system which is not used for emplacement of fluids underground.
