A process is disclosed for converting polyacrylamide gel into dilute aqueous solutions suitable for use in secondary oil recovery. Polyacrylamide gel is initially converted into a slurry of small gel particles in water from which forms a homogeneous solution concentrate which is then readily diluted to give the final drive fluid without any significant polymer degradation.
