Abstract:
Water injection (Waterflooding) has been implemented in the oil industry for a long time to maintain the reservoir pressure and increase the oil recovery from petroleum reservoirs. World energy demand would increase up to 36 % up till 2030 (Dudley 2013) which forces oil and gas industry to increase the recovery factors of oil and gas for all types of the reservoirs to meet the future energy demands. The oil recovery factor from petroleum reservoirs generally ranges from 10 to 35 % (Puntervold 2008). A considerable portion of current world oil production comes from mature fields and the rate of replacement of the produced reserves by new discoveries has been declining steadily over the last few decades (Manrique et al., 2012) Enhanced Oil Recovery methods will play a key role in meeting the energy demand in years to come by producing the recoverable oil resources in know reservoirs. (Stosur 2003)
Advanced water flooding is a collection of new and promising methods of enhanced oil recovery (EOR). Unlike other EOR methods, like surfactant or polymer flooding, the novel methods may improve the recovery without high additional expenses, and help to avoid accompanying logistical and environmental problems. The technology is called Smart Water flooding. The “SmartWater” injection strategy is based on experimental observations that variation of the injected water salinity and of its ion balance may result in large additional recovery (Tang and Morrow 2002;Web et al., 2005; Yildiz et al., 1996; Yusef et al., 2011;Yusef et al.,2011, Austad et al., 2008).
A short review of experimental studies (coreflooding experiments) in literature will be given, presentation of suggested working mechanisms along with some experimental results in KT DTU.
