With concerns about water scarcity in arid regions, innovative solutions are
imperative to meet the increasing water demand for Enhanced Oil Recovery (EOR)
processes. This article presents a study on the preparation of superhydrophobic
sand for water-saving and storage, with a focus on potential applications in EOR.
The results of the research indicate that the maximum water contact angle after
sand hydrophobization was 158°. The water storage capacity of the sand was
assessed by growing plants in soil layered with superhydrophobic sand. When
superhydrophobic sand was used both above and below the soil, the soil remained
moist for more than 10 days. In contrast, without the use of superhydrophobic
sand, soil moisture lasted for only 3 days. This research demonstrates the potential
of superhydrophobic sand in prolonging soil moisture, making it a valuable asset
for water-saving applications in EOR and arid regions.
