Hydrophobically associating polymers for enhanced oil recovery, part a: a review on the effects of some key reservoir conditions.

摘要: Abstract Research advancement in polymer flooding for Enhanced Oil Recovery (EOR) has been growing over the last decade. This growth can be tied to increased funding towards development of superior polymers such as hydrophobically associating when oil prices were high and increasing concern that “easy oil” exploited with focus now on “difficult extract” oil. The use EOR was discussed along its limitations. In this context, improved rheological properties cannot only linked molecular structures arising from different synthesis methods. Equally, external parameters similar conditions reservoirs affect these polymers. As such, review placed critical emphasis architecture route observed properties. addition, influence some key oilfield temperature, salinity, pH, reservoir heterogeneity behavior reviewed. respect, various findings garnered understanding correlation between critically For polymers, an (and hence method) is crucial successful design. However, must theoretically preferred application requirements (based parameters).
