Clay minerals damage quantification in sandstone rocks using core flooding and NMR

open access: yesJournal of Petroleum Exploration and Production Technology, 2018
Sandstone oil reservoirs consist of different clay minerals such as kaolinite, illite, and chlorite. These clay minerals highly affect the formation damage during enhanced oil recovery (EOR) and well stimulation operations in these reservoirs.
