Study on the Wettability and Spontaneous Imbibition Characteristics of Lacustrine Shale

Geofluids, Volume 2022, Issue 1, 2022., 2022
Wettability plays a significant role in the exploration and development of shale oil. The wettability affects the oil enrichment and restricts the selection of fracturing fluids. Shale is composed of complex minerals and organic matter. The pores composed of inorganic minerals have water wettability, while the pores composed of organic matter show the ...
