Because of its salt sensitivity polyacrylamide solutions, selected for polymer flooding for economic reasons have to be prepared in fresh water, and the highly saline reservoirs have to be preconditioned. The authors discuss two methods of preconditioning: a preflush with fresh water and use of a comparatively small slug of a less salt sensitive polymer. Results of laboratory work leading to the improved preconditioning concept with polymer are described. Case histories of two projects with both preconditioning processes are presented and discussed in detail.
