Low Salinity Oil Recovery – Log-Inject-Log

Abstract: Many laboratory coreflood studies have shown increased oil recovery is achieved by waterflooding using low salinity water, compared with injection of seawater or high salinity produced water. The reasons for this improved oil recovery are thought to be due to effective wettability changes and / or controlled removal of clay constituents. This paper describes a log-inject-log field test, designed to identify whether this phenomenon could be observed within the near well region of a reservoir. The log-inject-log… Show more

“…Figure 1 shows a representative distribution of incremental recovery from selected low salinity experiments and field cases. The sources are listed in Table 3 (Webb et al 2006, Vledder et al 2010, Brady et al 2015, McGuire et al 2005, Jerauld et al 2008, Batias et al 2009, Cissokho et al 2009, Shariatpanahi et al 2011, Yousef et al 2011, Fathi et al 2010, Hadia et al 2011, Skrettlingland et al 2010, Fathi et al 2011, Zhang and Sarma 2012, Zahid et al 2012, Sari et al 2017, Al-Attar et al 2013, Abulla et al 2012, Kulathu et al 2013. The data show that while about one-half of the studies found between 0 and 5% incremental or additional recovery of the original oil in place (OOIP), almost as many studies had 5-15% while a few reached incremental recoveries as high as 25% OOIP in both carbonate and sandstone rocks.…”

“…These review papers discuss a range of topics including proposed mechanisms of LSWF in sandstones and carbonates based on investigations at three different scales: (1) the core-to-reservoir scale, (2) the pore-network scale; (3) and the sub-pore scale (Bartels et al 2019). Table 2 lists publications that have proposed mechanisms for LSWF by categories (Webb et al 2006, Patil et al 2008, Berg et al 2009, Vledder et al 2010, Ashraf et al2010, Chen et al2004, Wideroee et al2010, Emadi et al2013, Mahani et al .2013, Romero et al 2013, Aghaeifar et al 2015, Yang et al 2015, Lager et al 2006, Sorbie et al 2010, RezaeiDoust et al 2011, Brady et al 2012, Fjelde et al 2013, Brady et al 2015, Tang et al 1997, Pu et al 2018, Kumar et al 2010, Fogden et al 2011, Zeinijahromi et al 2015, Hamouda et al 2014, McGuire et al 2005, Alotaibi et al 2010, Alvarado et al 2014, Moeini et al 2014, Ligthelm et al 2009, Lee et al 2010, Sorop et al 2013, Hiorth et al 2010, Pu et al 2010, Pinerez et al 2017, Fredriksen et al 2016, Sandgren et al 2011, Chavez-Miyauchi et al 2017…”

“…Injecting low salinity water (LSW) into petroleum reservoirs has been performed since the 1960s (Shalabi et al, 2014). Studies have claimed LSW injections in secondary and tertiary modes could improve oil retrieval, compared to injections with high salinity water (Aziz et al, 2020;Webb et al, 2003).…”

“…In this work, we injected smart water because of its results in increasing oil recovery according to many labs works and pilot based on the mechanisms that propose and qualify the effectiveness of smart water flooding such as: (i) Multicomponent ion exchange [1], (ii) Double-layer expansion [2], (iii) Reduction in interfacial tension and increased pH [3] (iv) Fines mobilization [4], (v) Mineral dissolution [5] (vi) Organic material desorption from the clay surface [6], (vii) Cation exchange on quartz surface [7] (viii) Desorption of organic materials from quartz surface [8].…”
