The potential prize of enhancing recovery rates with pulsed injection is enormous. A 1 percent improvement in recovery equates to 2 billion barrels of additional reserves worldwide; a 5% increase in recovery—a conservative increase thought to be achievable—would yield an additional 300 to 600 billion barrels. The application of pulsed injection can result in increased ultimate oil recovery from a field of between 5 and 10 percent depending on reservoir conditions. Can be used in conjunction with ASP to increase effectiveness Using Pulsed Injection to Extend the Life of Oil Fields
