Importance of wettability to rocks
WitrynaThis importance TE mainly arises from the widespread application of surfactants in foam generation, P wettability alteration, emulsion stability and well stimulation, even though surfactants are CE not always in charge of the large amount of oil production around the globe [16]. ... Based on these mechanisms, rock wettability is altered from ... WitrynaThe importance of increasing the water-film thickness becomes apparent from the following discussion. The more water-saturated rocks (τ w ≥ 0.5μ) compared to the less water-saturated rocks (τ w ≤ 0.2μ), with identical permeabilities, have a lower resistivity index or a lower true resistivity. This agrees with the idea of the dependence ...
