ABSTRACT:
A process for cyclically operating injection and withdrawal wells penetrating contaminated zones. A high flowrate portion of the cycle time preferably does not exceed a transient response period for in-situ formation fluids to achieve a quasi-steady state conditions. A low flowrate portion of the cycle time limits fluid flowrate which allows in-situ formation fluids to at least partially return to the zone affected by the high flowrate portion of the cycle. The cyclic operation produces improved remediation when compared to continuous operation of wells at similar operating conditions.
