Research on loss rules of oil and gas in preserved shale cores after open air exposure

Frontiers in Earth Science
There is a large amount of oil and gas loss in traditional conventional core samples. Revealing the rules of oil and gas loss is of great significance for restore the pristine oil content and oil component in the shale.

Evolution of Fractal Pore Structure in Sedimentary Rocks

Earth and Space Science, Volume 9, Issue 6, June 2022., 2022
Abstract Geological processes alter pore spaces over time, and their analysis can shed light on the dynamic fractal structure and fluid flow of rocks over time. This study presents experimental evidence to illustrate that the pore fractal structure evolves with sedimentation, carbonate cementation, clay growth, and dissolution.

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 ...
