4.4.2.2 EFFECT OF GAS WETTABILITY ON THE UNIDIRECTION SELF-
ADSORPTION OF CORES
The results of unidirection experiments of core columns with different gas
wettabilities in oil and water are as displayed in Fig. 4.24. From Fig. 4.24,it
can be seen that as the gas wettability of cores increases, curves of
