Investigation of pore-scale mixed wettability

Kumar, Munish; Fogden, Andrew; Senden, Timothy; Knackstedt, Mark


The efficiency of secondary and tertiary-recovery processes can be improved by properly taking into account the reservoir's true wettability state. Most reservoirs are assumed to be mixed-wet, based on core-scale indices such as Amott-Harvey and USBM. Oil/brine/mineral contact-angle measurements on smooth substrates offer some molecular-scale input and estimates for network modeling. However, direct experimental techniques to characterize wettability and validate the mixed-wet model at the pore...[Show more]
