Mechanisms of Spontaneous Imbibition and Wettability …
The basic performance of a novel high-efficiency spontaneous imbibition agent (SXJ-2) was investigated in this study. The mechanisms of spontaneous imbibition and wettability reversal of an oil-wet sandstone surface (OSS) by SXJ-2 were studied by infrared (IR) analysis, scanning electron microscopy (SEM), zeta potential determination, …

Mechanism of formation of wiggly compaction bands in porous sandstone
1 Introduction. Compaction bands (CBs) in porous sandstone have received increasing attention recently [Eichhubl et al., 2010; Fossen et al., 2011; Cecinato and Gajo, 2014].They are characterized by volume loss, some microfracturing, very little grain crushing, and lack of macroscopic shear offset across their plane [Sternlof et al., …
