Polymer EOR is a very promising technology in order to produce more oil from viscous oil reservoirs. Despite a long history of field implementation, some new findings are still emerging. In an environment of relatively low oil prices, a holistic approach has been developed in order to optimize the value of polymer projects. The objective is to achieve a better assessment of the incremental stakes, together with a better design of the polymer facilities from the injection to the final processing at the production. On top of classical polymer viscosity and propagation parameters acquisition, polymer oil relative permeabilities are measured and compared to water oil relative permeabilities. The impact of degradation is assessed, and included in the choice of the concentration. Injection facilities are tested and enhanced to minimize their foot print, limit mechanical degradation, and facilitate monitoring . New models of drag reduction and mechanical degradation are set for piping design. Water treatment process when polymer is back produced is optimized, not to jeopardize injectivity when PWRI is implemented. Through this approach, dedicated tools including laboratory set-ups and protocols, pilot scale facilities, and advanced modeling options have been developed for the benefit of any of our polymer projects.
