ABSTRACT:
A system for producing oil and/or gas from an underground formation comprising a first array of wells dispersed above the formation; a second array of wells dispersed above the formation; wherein the first array of wells comprises a mechanism to inject a miscible enhanced oil recovery formulation into the formation while the second array of wells comprises a mechanism to produce oil and/or gas from the formation for a first time period; and wherein the second array of wells comprises a mechanism to inject a remediation agent into the formation while the first array of wells comprises a mechanism to produce the miscible enhanced oil recovery formulation from the formation for a second time period.
