Experimental Study on Microscale Simulation of Oil Accumulation in Sandstone Reservoir

Frontiers in Physics, 2022
It is generally believed that conventional hydrocarbon accumulates in sandstone traps after migrating at a certain distance. Unconventional hydrocarbon only migrates at a short distance before accumulation or being imbibed in the tiny pores of shale and ...

Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

Advanced Materials, EarlyView.
Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Geochemical effects of intra-layer hydrocarbon micro-migration in shale layers: a case study of the No. 5 shale layer of the No. Ⅲ sand group in the upper submember of the third member of the Paleogene Hetaoyuan Formation in the deep sag area of Biyang Sag, Nanxiang Basin

Shiyou shiyan dizhi
Hydrocarbon micro-migration within source rock layers is an important pathway for shale oil enrichment, and the resulting geochemical effects provide strong evidence for its occurrence.
