Abstract Shale rocks are one of the world's most important unconventional gas resources today, thanks to technical advancements. Fluid adsorption in tight like shale is critical for designing fracturing and treatment fluids. However, fluids not fully understood, quantifying it remains difficult. In addition, complicated pore structure makes characterisation challenging. Wettability can be used ...

The imbibition has an important influence on the water injection development of ultra-low-permeability reservoirs. In this paper, nuclear magnetic resonance (NMR) high-temperature and high-pressure displacement system was used to simulate formation temperature pressure spontaneous single porosity medium dual (containing fractures), experiments at different rates were carried out. NMR T2 spectru...

Abstract The spontaneous imbibition (SI) process in shale oil reservoirs is not only influenced by capillary force, but also the osmotic pressure between fracturing fluid and formation water nanopores media. In this study, experimental methods are used to investigate mechanisms of osmosis SI, taking into account presence initial reservoirs. To effect osmosis, SI experiments were performed on fi...

Enhancement of salinity tolerance during seed germination is very important for direct seeding in rice. In this study, the salt-tolerant japonica landrace Jiucaiqing was used to determine the regulators that are involved in seed imbibition under salt stress. Briefly, the comparative proteomic analysis was conducted between dry (0 h) and imbibed (24 h) seeds with 150 mM NaCl. Under salt stress, ...

Crude oil-water interfacial tension in petroleum reservoir is reduced or increased due to surfactant injection retention, respectively. Changes the crucially attribute a governing capillary pressure and hence an oil displacement spontaneous imbibition process. The current study attempts elucidate influence of such changes on by replacing concentration consecutively with two approaches: sequenti...
