Importance of wettability to rocks
Witryna9 gru 2015 · The data showed that carbonate and clastic rocks behaved differently over a wide range of flow mechanisms and water saturations, proving that mineralogy plays a crucial role in the fluid displacement. Witryna19 paź 2024 · This task is of practical importance, because this comparative assessment makes it possible to predict a change in the wettability during phase transformations in carbonate rocks. The object for studying the specific features of the wettability of the intrapore space is a carbonate rock directly from an oil field.

Witryna20 mar 2024 · This work presents the development and standardization of a quick, easy, and low-cost wettability measurement method using the adherence tendency of rock particles in the oil or aqueous phase. The most important aspect of this study was establishing the optimum particle size for sustained floatation and balancing the … 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 ...
