... imbibition-recovery (IR) trio to investigate the recovery mechanisms in rocks with dual-wettability pore network. First, we evaluate the wetting affinity of five twin core-plugs from the Montney Formation by measuring spontaneous imbibition of reservoir oil and brine, and by measuring equilibrium contact...

... ( King, 2012 ; Cheng, 2012 ). Spontaneous imbibition of fracturing fluid is known as the primary mechanism for fracturing fluid loss and ineffcient water recovery ( Cheng, 2012 ; Bennion et al., 2005 ; Paktinat et al., 2006 ; Shaoul et al., 2011 ; Roychaudhuri et al., 2011 ). Other possible...

... formation water compared to the low salinity of fracturing and IOR fluids was investigated by performing spontaneous imbibition using both low and high salinity brines. It was concluded that in the oil-wet environment of the Bakken, the low salinity injection fluids can enter part of the reservoir because...
