Processes developed to increase recovery from reservoirs considered depleted by secondary recovery methods of waterflooding or gas injection were termed "tertiary recovery"; but the name was illsuited for recovery from reservoirs which would not respond to secondary recovery methods; this prompted introduction of the term "enhanced oil recovery."  3, record 1, English, - enhanced%20oil%20recovery
